Analysis for Cleanliness

You cannot control that which you do not measure.

In more and more industries, the exact knowledge of particle contamination is gaining in importance. Contamination of materials in dimensions of a few micrometers was mainly of concern for the pharmaceutical and semiconductor industries. However, not only manufacturers of circuit board components, but also traditional car parts suppliers face new demands on particle recognition and contamination source identification.

Cleanliness for the automotive parts manufacturers has become a huge topic in today’s ever challenging continuous improvement world. The need to define, measure and control the levels of particulate contamination on product is the new norm for suppliers and automotive OEM’s.

Cleanliness directly relates to product warranties, reliability, performance and safety issues. It has long been known that a dirty product gives us poor quality and low life expectancy. The dirtier the transmission from new, the less time it will last.

It is crucial now to identify particles and their source so that effective elimination can be achieved. Residual contamination consists of particles that persist on the component’s surface after the final step in manufacturing. Such contaminants are introduced via parts from suppliers or arise during processing. After vehicle assembly, the contaminant particles can cause severe damage, loss of function or reduce the lifetime of the product.

Cleanliness is defined as the contamination level of a component surface. Common measures to quantify the cleanliness are mass of the contaminants as well as number, size of the dirt particles. In general, the customer will specify contamination limits. The supplier then has to maintain these levels and document them regularly by means of contamination analysis.

The analysis of the contamination has to be proven to not affect the result and to be effective in evaluating all the contamination present. Methods of extraction and evaluation are specified in the international standard ISO 16232. Particular attention must be paid to the extraction method to ensure no contributing factors are introduced to the evaluation. There are different methods of counting the resulting extracted particles but by far the most accurate, repeatable and cost effective is automated microscope analysis. The microscope with software can scan the filter membrane; sort the particles by size class and even determine basic material composition (metal, non-metal, fiber). Once the data is gathered a custom report can be generated based on the customer requirements.

Activated Carbon Odor Combatant


Activated Carbon Odor Combatant

There are many stinky things in the world today. From the bathroom to the kitchen there are things in everyday life that can cause a nose to curl. However, activated carbon can quickly eliminate odors in the home, office, or commercial building. While many products simply mask odors or cover them up, activated carbon can absorb the odor and eliminate it once and for all. There are many ways that activated carbon can be used within a building to remove odor. Whether the smell is a permanent or occasional odor, activated carbon can be used to eliminate it.

Air Filtration Systems

An air filtration system can be placed on the air supply to any building to help eliminate the odors in the building. If there is a central heat and air system in the building the air filtration system can be used in the circulation process. A free standing air purification system can also be used in bathrooms that are used by numerous employees. These systems are much more effective than other means of removing odors.

Odor Blocking Masks

For those who work or play in environments that are not appealing to their noses there are activated charcoal masks that can be worn. These masks work to block the smells from reaching the nose. As the smell passes through the mask it is sucked up against the carbon and held there, eliminating the smell. These masks are perfect for those who work with garbage, waste, or cleaning products.

Flatulence Elimination pads and Inserts

Flatulence is a problem for many people today. Because of a fast paced environment and fast food restraints many people experience this condition. Luckily, there are now flatulence pads that can be used to eliminate the odor that accompanies flatulence. These pads can be placed in a chair for those in an office. However, there are also flatulence pads that can be placed inside the undergarment to eliminate odors.

Odor Eliminators for Pets

Activated charcoal can also be used to eliminate the odor that accompanies pet ownership. There are many smells that can come from litter boxes, accidents on the floor, and messes made in the yard. However, activated carbon can be made in the form of a powder. This powder can be sprinkled into the litter box, on the carpet, or in the yard outside. For use on the carpet in can be sprinkled on and then vacuumed up However, in other places it can be left to continue working. It is perfectly safe to use around pets and will not cause any harm if they ingest it.

There are many uses fro activated carbon today. It is an excellent odor eliminator. While these are many of the uses for eliminating odors there are many more. Anywhere there is a smell or odor; activated carbon can be used to eliminate it. This product is a green option for cleaning, absorbing, and eliminating odor. Activated carbon also has many other uses including purification, detoxification and moisture absorption.

Water Efficiency – The Resource Matrix Part 2 of 4 – Water’s Role in Global Warming

Last week, we introduced you to the Resource Matrix, which is everywhere, it is all around us. It is the world that has been pulled over your eyes to blind you from the truth.

We showed you how economics leads to people maximizing their benefits in “win-lose” propositions: you want diamonds and gold for nothing and they want to give you useless junk for a king’s ransom. And how we’ve been hypnotized in believing what they want is also what we want.

But the scales have been falling from our eyes, we’re beginning to see the truth, and the power has been shifting away from the “I want your goodies for nothing” crowd:

  • Do-gooders have increased our awareness and worked to change deals from “win-lose” to “win-win”
  • There is no “free lunch:” finite energy resources will run out; actions have consequences, and the consequences of our actions are already visible, rather scary, and quite irreversible; and that the “I want your goodies for nothing” crowd hasn’t been telling the truth

We now realize we’re all in this together: we have greater awareness of our actions and the desire to change, and have ways to change.

Hallelujah and Praise the Collective!

Today, we introduce the resource called water, its parallels with fossil fuels, and its role in global warming.

None of this is to dismiss or diminish the contribution of fossil fuels in global warming. Hey, just like the Special Olympics, if you participate, you get a medal. We just think that gold-medal winner Fossil Fuels has stolen the spotlight, letting silver-medalist Water Use keep us hypnotized in believing that water is a free lunch, and that nature will clear up polluted waters while getting away with breaking the rules.

Water, water, everywhere,
not a drop to drink.

According to our friends at How Stuff Works, who I wrote about sarcastically for their oxymoronic clean coal article in discussing how true public relations stuff really works, gives us this data:

  • 98% of the planet’s water is in the oceans. It’s salt water – we can’t drink it or irrigate our crops with it.
  • 2% is usable. Of that 2%:
    • 80% is locked up in polar ice caps and glaciers
    • 18% is underground in aquifers and wells
    • 1.8% is in lakes and rivers
    • 0.2% is elsewhere: either floating in the air as clouds and water vapor, locked up in plants and animals (and your body), and in foods and beverages.

Okay, so 20% of the usable water (only 0.4% of all water on Earth) is accessible, right?

Well . . . no. Many of the aquifers, wells, lakes, and rivers have been sucked dry like a once-juicy fly carcass in a spider’s web. (The 18% and 1.8% you see above is like the money in the Social Security Fund: there actually is nothing there.)

And many of those water sources that do still have a drop to drink are worse than the ocean’s salt water. Drink salt water and you’ll need to yawn into a bucket. Drink this water and you’ll kick the bucket.

And I know you aren’t asking this burning question:

“So . . . global warming to release fresh water from ice caps and glaciers is a good thing, no?”

Percentage this, percentage that.
Talk my language, will you?

I know I’m pulling the disgusting old government trick: drowning you in an ocean of water statistics.

So let’s make it plain and simple:

You bring in $10,000 a month. You’re also living high on the hog and doing your personal best to outshine every bling-bling Hip Hopster Musical Artist in materially conspicuous consumption:

  • $9800 goes to the McMansion mortgage and gold-plated Rolls Royce lease
  • $160.00 goes to investments in clothing and accessories
  • $0.40 has been lost in the sofa cushions
  • $39.60 a month is for everything else: food, phone and electric bills, income taxes, and all the other non-essentials: Don’t spend it all in one place!

Aquifers and wells and lakes and rivers:
Dry or polluted, oh my!

Fred Pearce, author of When the Rivers Run Dry, helps us quickly understand it:

We can all save water in the home. But as laudable as it is to take a shower rather than a bath and turn off the faucet while brushing our teeth, we shouldn’t get hold of the idea that regular domestic water use is what is really emptying the world’s rivers. Manufacturing goods … consumes a certain amount, but that’s not the real story either. It is only when we add in the water needed to grow what we eat and drink that the numbers really begin to soar. (emphasis mine.) (Fred Pearce, When the Rivers Run Dry, Boston: Beacon Press, 2006. p 3)

Here are a few numbers he gives:

  • to grow a pound of rice: 250 to 650 gallons of water
  • to grow a pound of wheat: 130 gallons
  • to produce a quart of milk: 500 to 1000 gallons
  • to produce a pound of cheese: 650 gallons
  • to produce a 1/4 pound of burger: 3000 gallons

He kindly puts water use into perspective in annual terms:

  • 1 ton (265 gallons) for drinking
  • 50 to 100 tons (13,250 to 26,500 gallons) around the house
  • 1500 to 2000 tons (397,500 to 530,000 gallons) for food and clothing

How Many Gallons to Produce One Pound of Beef?
Lies, damned lies, and statistics

US Beef industry’s Cattlemen’s Association: 441 gallons
Fred Pearce: 12,000 gallons
Water Footprint Network: 1854 gallons (calculations: 15500 litres of water per kg; 4079 gallons per kg; 1854 gallons per pound)

In an industrial beef production system, it takes an average three years before the animal is slaughtered to produce about 200 kg of boneless beef.

The animal consumes nearly 1300 kg of grains (wheat, oats, barley, corn, dry peas, soybean meal and other small grains), 7200 kg of roughages (pasture, dry hay, silage and other roughages), 24 cubic meter of water for drinking and 7 cubic meter of water for servicing.

This means that to produce one kilogram of boneless beef, we use about 6.5 kg of grain, 36 kg of roughages, and 155 litres of water (only for drinking and servicing).

Producing the volume of feed requires about 15300 litres of water on average.

—————————————–

Where does all that water come from?
From virtually everywhere

If it comes from imported goods (Thai rice or Egyptian cotton), the water comes from those countries.

When the water is collected from rivers or pumped from underground, as it is in much of the world, it’s:

  • increasingly expensive
  • increasingly likely to deprive someone of water (nothing to drink)
  • increasingly likely to empty rivers and underground water reserves

And when the rivers are running low, as they are more frequently, there is less water to grow anything at all.

The water used in growing and producing goods around the world is known as “virtual water” and the trade of these goods is known as “virtual water transfers.”

And who’s the biggest water exporting Mouseketeer of them all? The United States.

When you drink coffee from Central America, you are influencing the hydrology of the region, virtually taking a share of the Costa Rican rains. The same is true within a national and regional boundaries. The Colorado River is drained so Californians can eat their Big Macs and have friends over for a Sunday afternoon barbecue.

In the same way that your use of fossil fuel is measured as a “carbon footprint,” your water use, actual and through virtual water transfer, is measured as a “water footprint.”

How big is my water footprint?
I’ll show you mine if you show me yours

Arjen Y. Hoekstra, professor at the University of Twente, the Netherlands, introduced the water-footprint concept in 2002. It “shows water use related to consumption within a nation, while the traditional indicator shows water use in relation to production within a nation.” (Hoekstra and Chapagain, Globalization of Water, Malden: Blackwell Publishing, 2008, p. 3)

With Hoekstra and Chapagain’s water footprint calculator (waterfootprint.org), you select your country, input food, domestic water use, and industrial goods consumption, press a button, and you get your:

  • total water footprint for the year
  • bar charts for the three components
  • bar charts for individual food categories

For example, you’re in the US, eat only 1 pound of cereal a week (.4545 kg) and have a low-fat, low-sugar diet, use a low-flow showerhead, use a no-flush eco-toilet, and never run the tap while brushing your teeth. Two extremes:

  • You’re the hippiest of the hip: making $10,000 a year: Your water footprint: 245 cubic meters (65,170 gallons)
  • You’re the hippiest of the Yuppies: making $120,000: Your water footprint: 2979 cubic meters (792,414 gallons). Difference due to your income’s effect on industrial production.

Three notes on the calculations, because Professor Hoekstra is European and lives in the social welfare country that started birthing hippies in Amsterdam decades before they showed up in the US at Woodstock:

  1. You input kilograms for food:
    • 1 kilogram = 2.2 pounds = 35.2 ounces
    • 1 ounce = 0.028 kilograms. 1 pound = 0.454545 kilograms
  2. Your water footprint is in cubic meters per year:
    • 1 cubic meter = 35.3 cubic feet = 266 gallons
  3. The higher your income, the greater your water footprint, even if you don’t personally consume anything: you’re a capitalist pig supporting the Establishment Regime, I guess

So how is Cinnamon’s capitalist water footprint? Answer: 650 cubic meters (172,900 gallons)

I showed you mine. Now you show me yours:

Get the naked truth: Calculate your waterfootprint now:

Water’s running out:
I get the fossil fuel analogy so far.
And what about climate change?

We return to Fred Pearce’s book to find an example, of which he has oceans:

China’s Yellow River: The fifth longest in the world, it begins high in the mountains of eastern Tibet and journeys more than 3000 miles. Almost half a billion people depend on it for drinking and crop irrigation, and it’s made China the world’s largest wheat producer and second largest corn producer. Yet more than half of the lakes it feeds have disappeared over the last 20 years, and a third of pastures have turned to desert. This desertification generates huge dust storms that choke lungs in Beijing, close schools in Koreas, dust cars in Japan, and rain dust on mountains across the Pacific and Western Canada.

State irrigation projects along the Yellow River soak up the majority of its water – the total official allocations are greater than the actual flow.

The resulting drought could be an early warning sign of global warming.

Much of the declines in moisture reaching rivers is in line with prediction of climate researchers. So how does this global warming happen?

Higher air temperatures from desertification increase evaporation from oceans and intensify the water cycle. This increases atmospheric water vapor – 8 to 10% more than today. This increases global rainfall, but the rain is being redistributed: middle latitudes (read: the US) are becoming drier. Higher temperatures increase evaporation on land, meaning soil dries out faster, meaning less rainfall is reaching rivers.

The higher temperatures melt glaciers and snowpacks. At first, this leads to unpredecented floods. After the glaciers disappear, meltwaters that feed rivers disappear. The combined decreasing rainfall and increasing evaporation will lower moisture by 40% in the southern and western states.

The Sierra Nevada snowpack could diminish by 70 to 80 percent over the next 50 years. And some of the world’s most productive agricultural regions could dry up.

Global climate is becoming more extreme: the dry areas become drier, and the wet areas become wetter. And more areas are becoming dry deserts. Loss of habitat and agricultural lands. It’s a vicious cycle.

So what can you do?
Navigating through the Resource Matrix

As Fred Pearce points out, your drinking and bathing account for 0.05% of your total water consumption. Your food and clothing weigh in at 95.00%, although I find his 12,000 gallons needed to produce a pound of burger rather wild.

As Professor Arjen Y. Joekstra shows with his Water Footprint Calculator, your consumption of meats accounts for a lot, as does your guilt by association of being in an industrialized country.

The obvious solution: eat fewer e-coli burgers from your neighborhood Salt and Fat Slop Bucket restaurant.

The wiser solution: like your choices in energy use, become more aware of the resources needed to produce anything and the consequences. Such as luxurious cotton grown in the Egyptian desert.

Next article in the water efficiency series:
How an illiterate, lice-infested, foul-mouthed
peasant on some other side of the globe affects you

We continue going with the flow of water, when we show the parallel between the current hot Oil Wars and in the future cold Water Wars.

And all of this is for one purpose:

To help you see the Resource Matrix, everywhere, all around you.

Tips For Driving Green

Are you trying to make changes in your lifestyle that will help to preserve some of the natural resources being used everyday? There are many things that individuals can do to make a difference. However, one of the biggest concerns is the problems caused by all the vehicles being driven today. Everyone knows that vehicles put out gas emissions that add to the amount of air pollution already causing problems for humanity. But what can you do?

Very few people can do without some sort of vehicle in today’s society. It would be almost impossible to get from one location to another without driving most of the time. Still, it’s important to do all you can to reduce the amount of pollution being emitted into the air. Since buying a hybrid is not an option that everyone can take advantage of, here are a few tips for driving green that will help reduce pollution caused by vehicles.

• Proper Maintenance – One of the best things that you can do to make sure you’re driving green is to keep the maintenance up on your vehicle. Keep it tuned up, air filters changed and make sure the tires are inflated properly.

• Carpool When Possible – It may not always be possible to carpool but do so whenever you can. This will make more of a difference than you might think.

• Plan Your Trips: If you plan your trips in advance you can cut down on your driving time. You can plan the shortest route that will accomplish everything you need to get done. Stop by the store on your way home from work instead of going home first and leaving again. Anything that reduces your driving time will help.

• Walk More – When you’re visiting a neighbor, going to the local park or anywhere that is near your home, try walking whenever it’s practical to do so.

• Cut Down on the AC – Only use the air conditioning whenever it’s absolutely necessary. You can roll down the windows other times to let a breeze blow through.

• Drive Smart – Driving smart includes avoiding sudden stops and starts and driving the speed limit. Speeding uses more gasoline and produces more pollution than necessary.

These are all simple and easy things that everyone can do to help the environment. If every driver were to make these changes it would make a huge difference in the amount of pollution created each day.

Water Efficiency – Water Used in Generating US Electricity


Water Efficiency – Water Used in Generating US Electricity

In my four-article series on water use (The Resource Matrix), I took you on a journey to reveal the layers of The Resource Matrix in order to help you understand how water will be a highly contested commodity tomorrow, possibly as much as oil is fought over today.

You learned about your water footprint and a website where you can calculate it, virtual water and virtual water transfers, whereby choices here affect water availability elsewhere, to the point of some people not having enough water to drink in order to produce inexpensive dyed cotton, along with insane choices such as growing crops in the desert.

You learned that on average it takes 1854 to 3000 gallons to produce one pound of beef.

Yep, it’s it’s been a great journey through the sidetrip city of the Resource Matrix.

Today, we’ve found the on-ramp to the Green Lighting Interstate and are driving to take a look at water use in generating electricity.

For a simple reason. It takes a lot of water to produce electricity.

How much? 5% of all US water? 10%? Can’t be as high as 25%?

Electricity and water?

I thought the issue was fossil fuels and greenhouse gases

The U.S. Geological Survey (USGS) estimated water use in the United States in 2000.

Their grand total: 408 billion gallons per day withdrawn for all uses.

The number 1 spot, weighing in at 48%, was thermoelectric power.

Irrigation earned the runner-up prize at 34%.

The 195 billion gallons need to come from somewhere, and actions have consequences. Environmental ones, as in 40 million fish in the Great Lakes killed each year due to being trapped against water intake devices. That’s a lot of Friday night fish dinners.

How much water is used in generating electricity?

Large fossil fuel and nuclear plants require incredible quantities of water for cooling and ongoing maintenance.

Water for thermoelectric power is used in generating electricity with steam-driven turbine generators. It uses 48% of all water in the US.

According to the Pace Energy and Climate Center, the amount of water used for power plant cooling varies by each specific power plant’s electricity generating technology and size. Nuclear reactors require the most water for cooling, and baseload fossil fuel power plants come in second.

The Salem Nuclear Generating Station alone takes 3 billion gallons a day from the Delaware Bay, according to the Pace Energy and Climate Center.

Nationally:

  • Steam electric generating plants across the nation draw in more than 200 billion gallons per day.
  • Nuclear and fossil fuel power plants drink over 185 billion gallons of water per day.
  • Geothermal power plants add another 2 billion or so gallons a day.
  • Most renewable energy technologies require little or no water for cooling.

These numbers are starting to sound like the same ones the U.S. Treasury and Federal Reserve Bank use.

Imagine watching your favorite science program where astronomers explain that the universe is 78 billion light-years wide (78 billion units of 5,878,630,000,000 miles). There is absolutely nothing in our experience to help us wrap our mind around it.

How much is 3 billion gallons per day?

The Delaware Bay feeds Salem Nuclear Generating Station 3 billion gallons a day.

Imagine this rectangle: a football field with end zones (360 feet long x 160 feet wide). Then add to it walls on each side of the rectangle to create a container to hold the 3 billion gallons you pour into it.

How high do you need to make those walls to contain 3 billion gallons? 6915 feet high. Or 1.3 miles.

Maybe 6915 feet high is still hard to imagine. So how deep do you cover the field in order to feed the Salem plant every minute? Answer: 5 feet deep. Every minute.

48% of all water use: We’re Number One!

How much is 195 billion gallons per day?

Using the USGS figure for 2000, thermoelectric power nationwide used 195 billion gallons a day, or 48% of all water used in the US. My guess is the water use has grown since then.

How high are the walls on our football field now? 449,475 feet or 85 miles high. We’re back to US Treasury and astronomy numbers again.

So, let’s get a higher-level view to help us.

Lake Erie holds 116 cubic miles of water.

Nationally, thermoelectric power uses 195 billion gallons a day – or 64.2 cubic miles a year.

We drain Lake Erie every 22 months.

But the water used is returned to its source.

So what’s the issue about water use?

Power generation returns 98% of the water back to its source (bay, lake, river, ocean).

It’s the environmental consequences.

The Pace Energy and Climate Center explains it neatly:

Withdrawal of large volumes of surface water for either power plant cooling or hydropower generation can kill fish, larvae and other organisms trapped against intake structures (impinged), or swept up (entrained) in the flow through the different sections of a power plant.

Examples include:

  • The Salem Nuclear Generating Station is responsible for an annual 11 percent reduction in weakfish and 31 percent reduction in bay anchovy.
  • At the Indian Point 2 and 3 reactors on the Hudson River, the number of fish impinged totaled over 1.5 million fish in 1987.
  • The 90 power plants using once-through-cooling on the Great Lakes kill in excess of 40 million fish per year due to impingement. (Once-through cooling needs a continual flow of new water, and uses 30 to 50 times that of a closed cycle system. Closed cycles cool down water from steam then reuse it.)

The diversion of water out of the river removes water for healthy in-stream ecosystems:

  • Stretches below dams are often completely de-watered.
  • Fluctuations in water flow from peaking operations create a “tidal effect,” disrupting the downstream riparian community that supports its unique ecosystem.
  • A dam’s impoundment slows water flows, which hinders natural downstream migration of many fish species.
  • By slowing river flows, dams also allow silt to collect on river and reservoir bottoms and bury fish spawning habitat. Silt trapped above dams accumulates heavy metals and other pollutants. Disrupting the natural flow of sediments in rivers also leads to erosion of riverbeds downstream of the dam and increases risks of floods.
  • The impoundment of water by hydropower facilities fundamentally reshapes the physical habitat from a riverine to an artificial pond community.
  • This often eliminates native populations of fish and other wildlife.
  • Dams also impede the upstream and downstream movement of fish and other wildlife, and prevent the flow of plants and nutrients. This impact is most significant on migratory fish, which are born in the river and must migrate downstream early in life to the ocean and then migrate upstream again to lay their eggs (or “spawn”).
  • As mentioned above, withdrawal of water into turbines can also impinge or entrain significant numbers of fish.

The cleanest kilowatt is the one never used:

Back to those compact fluorescent lamps and LEDs

PowerScorecard.org explains the solution:

By re-directing electricity dollars to support environmentally benign energy resources, consumers are empowered, in states that offer supply choice, to influence the existing generating resources that are deployed to meet demand.

They can also support the construction of new and cleaner electricity resources that will be built to meet overall growth in demand in the future. By supporting these power options, consumers can minimize many water use and consumption impacts. Still, directing your dollars to cleaner power products in no way helps remediate damages that already have occurred. Consumers can stop the construction of new hydropower facilities or alter conditions of siting and operation, but they cannot undo previous environmental degradation that occurred at existing hydropower facilities.

In short, reduce your use of electricity.

Real Threat is Hazardous Waste


Real Threat is Hazardous Waste

For those staying in urban and suburban areas, we enjoy the regular collection of waste and recyclable materials. However, what most of us are not aware is the waste that is brought to dumps is actually many times more toxic than it was 30 years ago.

Hazardous Home Wastes

It is surprising just how toxic our world has become in just a few years. Synthetic chemicals didn’t even exist in any significant numbers before the turn of the 20th century. In the past, home furnishings were made of natural materials, such as carpets, pillows, curtains, bath items and towels. The things that are in the most and close contact with us each day, especially those made before 1980, were made of sustainable and renewable resources.

However, this is no longer true today. Every time when we replace our furnishing, we are trashing away materials that could contain chemicals, such as batteries and electronics. These home wastes are part of the hazardous waste brought to dumps each day.

Hazardous Waste In Overwhelmed landfills

In many countries, the problem of hazardous waste is compounded by the crisis of overwhelmed landfills. The danger from this waste getting loose in the environment is even more serious and precarious than ever. Increased danger of containment systems being breached is very real.

As pressure on forest and agricultural lands mounts, erosion due to major storm events could unleash these toxins into the ecosystems that is already fragile and damaged. Hazardous waste is becoming an acute problem beyond management in many countries.

Paint That is Environmentally Friendly, Should I Really Buy Into It?

Over the past few years, more and more people have become quite aware of the need to take care of the environment and take responsibility for our part in saving the planet from ecological disaster brought on by the inventions and waste products created by man. As a natural result of the many developments, inventions, and innovations made by man, the environment has slowly been degraded to the point that it has become a real point of concern for everyone living on the planet. The toxic byproducts of the manufacture of most of the inventions of man have slowly choked and poisoned the environment, slowly producing adverse conditions that would take years to undo, if at all. Other than the production of fuels and modern lubricants, another source of chemical pollutants that are not only toxic to the environment but also directly to humans as well, are the various paints being made in manufacturing plants. These paints have pigments that are laced with lead, and this lead is a heavy metal that is highly toxic.

Thankfully, some paint manufacturers have taken the problem to heart and devised new compounds that are lead free and contain no other toxic chemicals, in effect, environmentally friendly paint. This is probably one of the best developments in the field of synthetic materials, since having environmentally safe paint is beneficial not only to the environment long term, but also directly and immediately upon humans, since this paint does not exude the strong toxic fumes that people have come to associate with freshly applied paint. Environmentally friendly paint is in many ways better then the traditional paint of old, not only in the fact that it will not poison the environment, and the residents of the house using it eventually, but also because of the fact that formulation of the environmentally safe paint actually allows it to dry quite faster than traditional paints. What’s more is that the colors found available in environmentally friendly paint are as varied as the ones you find in traditional paint, so finding the paint color that you like in non-toxic form should be quite easy now.

In case you are wondering just how environmentally safe paint is beneficial to you, here are just a few pointers:

Not a health hazard

There are millions of people with both diagnosed and undiagnosed chemical allergies that are easily triggered by numerous stimuli, and one of the most popular irritants are the traditional paints and their strong, noxious fumes. Environmentally friendly paint exudes little, if at all, chemical fumes when they are applied and while they are drying, making it ultimately ideal for the home and for places where people tend to stay indoors for a long period of time.

Safe for the environment

Like the name suggests, environmentally safe paint is just that, safe for the environment. Production of this type of paint did not in any way contribute to the contamination of groundwater and landfills, and does not have any substance in it that will deplete the ozone layer even faster. This is the entire reason for making this type of paint. Rest easy knowing that as you use environmentally friendly paint, you are in no way damaging the environment

Cost-efficient and effective

Environmentally friendly paints are known to perform rather well in coverage, scrubability, and in hiding the flaws that came out during previous coats of paint. People who have used environmentally safe paints say that the paint itself has enough body to allow more areas to be covered with the same amount of paint that would normally only cover a smaller surface area. This translates into significant savings by not having to buy more paint than is necessary.

Water-based paint

Being water based means it can be easier to clean, since it will not retain and absorb dirt and other stains, much like what traditional paint tends to do. A lot of discoloration in old paints is primarily because of dust and dirt actually seeping into the paint, causing it to grow darker and uneven in color.

Recycle, Reuse and Reduce

Does you family recycle aluminum cans? Do they do it to get a little extra cash or because it is the responsible thing to do? How much do they, and you, know about what happens to the can after the soda is gone? Here is a quick true and false quiz on recycling. It will only take 2 or 3 minutes to find out what you know and what you need to know about the importance of families recycling.

Circle the answer for each of the 6 questions. Now test the other members of the family.

1. In the time it takes you to read this question, 50,000 12-ounce aluminum cans are made.

                  True or False

2. When you recycle one aluminum can you save enough energy to equal a half gallon of gasoline?

                  True or False

3. There is no limit to the amount of times aluminum can be recycled.

                  True or False

4. We use over 80,000,000,000 (billion!) cans a year.

                  True or False

5. At one time, aluminum was more valuable than gold.

                  True or False

6. More aluminum goes into beverage cans than any other product.

                  True or False

Surprise! All of the answers are true.

Did you know that for every $10 spent buying things $1 or 10% goes for packaging that is thrown away. Packaging, and that includes aluminum cans, represents 65% of household trash. Wow. What a waste of money and resources. We can do better than that.

Our family is making a special effort to Recycle, Reuse and Reduce. Will you join us in helping to protecting our earth and natural resources? Maybe your family could put up a special box to save aluminum cans for the recycling center.

Water Efficiency – Water Used in Generating US Electricity

In my four-article series on water use (The Resource Matrix), I took you on a journey to reveal the layers of The Resource Matrix in order to help you understand how water will be a highly contested commodity tomorrow, possibly as much as oil is fought over today.

You learned about your water footprint and a website where you can calculate it, virtual water and virtual water transfers, whereby choices here affect water availability elsewhere, to the point of some people not having enough water to drink in order to produce inexpensive dyed cotton, along with insane choices such as growing crops in the desert.

You learned that on average it takes 1854 to 3000 gallons to produce one pound of beef.

Yep, it’s it’s been a great journey through the sidetrip city of the Resource Matrix.

Today, we’ve found the on-ramp to the Green Lighting Interstate and are driving to take a look at water use in generating electricity.

For a simple reason. It takes a lot of water to produce electricity.

How much? 5% of all US water? 10%? Can’t be as high as 25%?

Electricity and water?

I thought the issue was fossil fuels and greenhouse gases

The U.S. Geological Survey (USGS) estimated water use in the United States in 2000.

Their grand total: 408 billion gallons per day withdrawn for all uses.

The number 1 spot, weighing in at 48%, was thermoelectric power.

Irrigation earned the runner-up prize at 34%.

The 195 billion gallons need to come from somewhere, and actions have consequences. Environmental ones, as in 40 million fish in the Great Lakes killed each year due to being trapped against water intake devices. That’s a lot of Friday night fish dinners.

How much water is used in generating electricity?

Large fossil fuel and nuclear plants require incredible quantities of water for cooling and ongoing maintenance.

Water for thermoelectric power is used in generating electricity with steam-driven turbine generators. It uses 48% of all water in the US.

According to the Pace Energy and Climate Center, the amount of water used for power plant cooling varies by each specific power plant’s electricity generating technology and size. Nuclear reactors require the most water for cooling, and baseload fossil fuel power plants come in second.

The Salem Nuclear Generating Station alone takes 3 billion gallons a day from the Delaware Bay, according to the Pace Energy and Climate Center.

Nationally:

  • Steam electric generating plants across the nation draw in more than 200 billion gallons per day.
  • Nuclear and fossil fuel power plants drink over 185 billion gallons of water per day.
  • Geothermal power plants add another 2 billion or so gallons a day.
  • Most renewable energy technologies require little or no water for cooling.

These numbers are starting to sound like the same ones the U.S. Treasury and Federal Reserve Bank use.

Imagine watching your favorite science program where astronomers explain that the universe is 78 billion light-years wide (78 billion units of 5,878,630,000,000 miles). There is absolutely nothing in our experience to help us wrap our mind around it.

How much is 3 billion gallons per day?

The Delaware Bay feeds Salem Nuclear Generating Station 3 billion gallons a day.

Imagine this rectangle: a football field with end zones (360 feet long x 160 feet wide). Then add to it walls on each side of the rectangle to create a container to hold the 3 billion gallons you pour into it.

How high do you need to make those walls to contain 3 billion gallons? 6915 feet high. Or 1.3 miles.

Maybe 6915 feet high is still hard to imagine. So how deep do you cover the field in order to feed the Salem plant every minute? Answer: 5 feet deep. Every minute.

48% of all water use: We’re Number One!

How much is 195 billion gallons per day?

Using the USGS figure for 2000, thermoelectric power nationwide used 195 billion gallons a day, or 48% of all water used in the US. My guess is the water use has grown since then.

How high are the walls on our football field now? 449,475 feet or 85 miles high. We’re back to US Treasury and astronomy numbers again.

So, let’s get a higher-level view to help us.

Lake Erie holds 116 cubic miles of water.

Nationally, thermoelectric power uses 195 billion gallons a day – or 64.2 cubic miles a year.

We drain Lake Erie every 22 months.

But the water used is returned to its source.

So what’s the issue about water use?

Power generation returns 98% of the water back to its source (bay, lake, river, ocean).

It’s the environmental consequences.

The Pace Energy and Climate Center explains it neatly:

Withdrawal of large volumes of surface water for either power plant cooling or hydropower generation can kill fish, larvae and other organisms trapped against intake structures (impinged), or swept up (entrained) in the flow through the different sections of a power plant.

Examples include:

  • The Salem Nuclear Generating Station is responsible for an annual 11 percent reduction in weakfish and 31 percent reduction in bay anchovy.
  • At the Indian Point 2 and 3 reactors on the Hudson River, the number of fish impinged totaled over 1.5 million fish in 1987.
  • The 90 power plants using once-through-cooling on the Great Lakes kill in excess of 40 million fish per year due to impingement. (Once-through cooling needs a continual flow of new water, and uses 30 to 50 times that of a closed cycle system. Closed cycles cool down water from steam then reuse it.)

The diversion of water out of the river removes water for healthy in-stream ecosystems:

  • Stretches below dams are often completely de-watered.
  • Fluctuations in water flow from peaking operations create a “tidal effect,” disrupting the downstream riparian community that supports its unique ecosystem.
  • A dam’s impoundment slows water flows, which hinders natural downstream migration of many fish species.
  • By slowing river flows, dams also allow silt to collect on river and reservoir bottoms and bury fish spawning habitat. Silt trapped above dams accumulates heavy metals and other pollutants. Disrupting the natural flow of sediments in rivers also leads to erosion of riverbeds downstream of the dam and increases risks of floods.
  • The impoundment of water by hydropower facilities fundamentally reshapes the physical habitat from a riverine to an artificial pond community.
  • This often eliminates native populations of fish and other wildlife.
  • Dams also impede the upstream and downstream movement of fish and other wildlife, and prevent the flow of plants and nutrients. This impact is most significant on migratory fish, which are born in the river and must migrate downstream early in life to the ocean and then migrate upstream again to lay their eggs (or “spawn”).
  • As mentioned above, withdrawal of water into turbines can also impinge or entrain significant numbers of fish.

The cleanest kilowatt is the one never used:

Back to those compact fluorescent lamps and LEDs

PowerScorecard.org explains the solution:

By re-directing electricity dollars to support environmentally benign energy resources, consumers are empowered, in states that offer supply choice, to influence the existing generating resources that are deployed to meet demand.

They can also support the construction of new and cleaner electricity resources that will be built to meet overall growth in demand in the future. By supporting these power options, consumers can minimize many water use and consumption impacts. Still, directing your dollars to cleaner power products in no way helps remediate damages that already have occurred. Consumers can stop the construction of new hydropower facilities or alter conditions of siting and operation, but they cannot undo previous environmental degradation that occurred at existing hydropower facilities.

In short, reduce your use of electricity.

Are Tsunami’s Caused by Global Warming ?


Are Tsunami’s Caused by Global Warming ?

Throughout the history of our planet it has endured a constantly changing climate. It endured an ice age and has also experienced long periods of heat. But over the last two hundred years, give or take, the temperature of our planet has been steadily increasing. This change in the climate on earth is known as global warming, and global warming is the direct result of the industrial revolution.

Because of the industrial revolution, people are constantly burning fossil fuels such as oil and coal. But by burning these fuels dangerous greenhouse gases like carbon dioxide (CO2) are then released into the earth’s atmosphere. These gases block heat rising from the earth from being able to escape into space. The same basic function that glass panels on greenhouses have, hence the name. Our burning of fossil fuels causes more than three quarters of all carbon dioxide emissions. Power plants and other stationary sources contribute more than half of that amount.

Along with increasing CO2 emissions, deforestation is on the increase as well. This is disastrous, because trees recycle CO2 and release oxygen back into the atmosphere. Because of the rise in deforestation levels the fossil fuels we burn are seriously jeopardizing our planet. We know that global warming is the cause of glaciers getting smaller and for the rise in sea levels. Plants and animals show clear and undeniable signs that they are affected in many different ways. Earth is experiencing longer seasons which results in rivers and lakes freezing later than usual and melting sooner. Without a doubt, global warming causes many changes and affects our planet in many ways but can it also cause a tsunami?

Nobody will ever forget the utter destruction, grief and loss left behind after the huge tsunami that hit parts of Asia on December 26th, 2004. Hundreds of thousands of people were killed, injured and traumatized. The areas it hit were left completely destroyed.

Generally speaking a tsunami is made up of a series of waves. More often than not the first one is the mildest. Prior to the arrival of the first wave, the shoreline recedes dramatically and often leaves the ocean floor exposed. They mostly occur where the water is shallow but they can also occur around coastal areas. In deep water a tsunami appears as a big wave and nothing more. In shallow water this is not the case. The wave can reach as high as one hundred metres, although, in all honesty, this is not at all common.

We know that tsunami’s can be caused by an earthquake, but this is not the only cause. They can also be caused through volcanic eruptions and landslides. Another cause is if a large amount of water is somehow displaced, such as when meteors happen to fall into large bodies of water. Tsunami’s are caused by events that can be, and are, affected by global warming, however global warming itself does not directly trigger the formation of a tsunami. Basically, it is an indirect cause.

One thing is certain, global warming is not a myth as some suggest. The planet is displaying clear signs that we dare not ignore.
