Economic Sustainability: Reforming Production

April 8th, 2010

In our current industrial economy people are paying for the fair cost of goods.  RIGHT!?

What if that’s not the case.  What if what we’re really paying is a falsified notion of the cost?  A number that doesn’t reflect the real price of production.  Let me explain:

When a commodity is priced for the market, let’s say a cow, both the cost of production and the value of the product are taken into consideration.  To price a cow we would look at its production: $100 for cultivation of hay, $5 on medicine, $200 in labor for the ranch hands, and $45 dollars on butchering.  So in this case a cow, which (priced by the pound) costs about $350.  That seems reasonable.

But it isn’t.  This fails to consider that factory farm conditions form giant cesspools of fecal material that release enormous amounts of toxic gas, and render the land in their vicinity unusable.  That the over farming of cattle is depleting the nutrient rich topsoil little by little until it will be rendered unusable to grow anything.  That the overuse of antibiotics are developing resistant strains of bacteria that increase medical expenses for cows and humans alike.  These costs are ludicrous! The thing is, we just haven’t had to pay them yet.  These effects don’t really become a problem until they reach a critical mass, at which point it will be too late to deal with them effectively.

Organic grass-fed cows, or cows that are raised in the manner to which they are adapted by nature (as oppose to corn fed, antibiotic laden factory cows), have much healthier lives, are healthier to eat, and taste better.  The problem for consumers is that the meat is prohibitively expensive.  The grass fed cows are mostly raised in a sustainable way; one that supports the ecosystem, and encourages health and biodiversity.  The cost of the organic grass fed beef, while higher represents the true cost of production.  The other beef saves you a few dollars at the cost of the future of our nation.

A parallel can be drawn to most other good and commodities.  Some are sustainable, and reflect the true cost of production, like organic grass-fed beef.  Others save you a few pennies, and fail to inform their true cost is decay to the very ecosystem, or social system upon which you depend

Nobel prize winner Paul Krugman recently wrote an article about the changes that need to be made.  It was published in the NY Times:

Wolf in Sheep’s Clothing: When Green Tech isn’t Green

February 18th, 2010

Published by EU Infrastructure.

Everyone knows that finding a renewable source of energy is crucial to wean the world off fossil fuels and cut carbon emissions, but what are we willing to sacrifice for clean energy?

In Brazil, the government has given the green light for the construction of a massive hydroelectric dam that will be able to generate enough energy for over 23 million homes. However, its creation will see the flooding of huge portions of the Amazon basin, displacing indigenous tribes and putting 500 sq km of rain-forest underwater. The creation of the Belo Monte Dam is expected to begin in 2015 and is rumored to cost around $17 billion. Set to be situated on the Xingu River, a tributary of the Amazon in the northern state of Para it has been abandoned several times, noticeably in the early 90s due to its controversial nature and widespread global protests.

Lasers Take Science One Step Toward Unlimited Clean Energy

February 8th, 2010

Radical technological advances, cold fusion being an example, seem to belong in Star Trek episodes rather than credible scientific discussion.  Last month one of these “far out” technologies, specifically the availability of unlimited energy, received an unexpected step towards plausibility from the scientists in Lawrence Livermore Labs.

The scientists, headed by Siegfried H. Glenzer and L. Jeffrey Atherton, are using 192 high powered lasers to focus large amounts of energy on a very small particle.  The goal is to achieve “ignition,” or to heat the small elemental speck to millions of degrees Fahrenheit nearly instantly, creating a small scale reaction of our own sun.  Once perfected, this reaction could yield a virtually limitless supply of clean energy.

“We’re confident of our ability to start seeking ignition this summer,” Atherton said in an interview. “And we’re optimistic that at some point soon we’ll achieve it.”

A recent article published by SFGate.com states:  “To achieve that thermonuclear reaction, the scientists will attempt to use the lasers’ immensely powerful beams to reach temperatures of more than 200 million degrees Fahrenheit and pressures millions of times greater than Earth’s atmosphere – conditions found only in the interior of the sun and stars…

“If those experiments succeed, the hydrogen isotopes would be crushed instantly and explode inward until they fuse and yield vastly more energy than the laser beams had pumped into them.”

One small step for lasers… one giant leap for Clean Tech.

A Grammy for Green Tech: The Clean Tech Open

February 4th, 2010

Did you watch the Grammy Awards this week?  I did.  It got me thinking: they should have awards like this for every profession, especially green tech!  One web search later, I found they exist! The award ceremony is called the Clean Tech Open, and it was most recently held in San Fransisco, featuring the latest green thinkers from every section of the US.  Recently Popular Mechanics did a feature article of a few prize winners:

Green Building Award: BottleStone

“…a combination of clay, cement, and old glass that looks uncannily like real granite, but takes much less energy to produce…”

Transportation Award: ElectraDrive

“…ElectraDrive aims to make electric conversion more accessible to the masses with its one-size-fits-all conversion kit. The kit’s designed to turn just about any car into an EV, whether it’s a sleek convertible or a hulking truck—you just take your car’s gas drivetrain out and put the company’s ElectraMount module in…”

Energy Efficiency Award: Viridis Earth

“…Viridis Earth manufactures $350 retrofit devices that can make your old a/c unit an energy-efficient wunderkind. One device cuts an air conditioner’s energy consumption by 20 to 30 percent, a reduction so substantial that the retrofit typically pays for itself in less than a year…”

Renewables Award: Focal Point Energy

“Lots of companies that use hot water or steam for manufacturing rely on gas or electricity to generate their heat. But it’s much more efficient to gather sunlight and use it to heat the water directly…  “To collect the heat, we use a reflective membrane made out of a Mylar-like material,” says Howard Harrenstien… The reflector focuses incoming sunlight into a concentrated beam, which can then be aimed at water-filled containers to make the contents boil.”

Green Building Award runner-up: Solar Red

“…By devising a system that can be put up by the same guys who nail on your roof tiles (no professional solar installer required), Solar Red has succeeded in cutting the cost of home solar by 25 to 50 percent…”

Energy From Thin Air

October 7th, 2009

In our pursuit of green, clean energy it seems that we are going back to basics. Over five thousand years ago sailors used wind for travel and millers harnessed it to crush grain into flour.

Wind power is growing exponentially in this country.  Over the last five years wind power has quadrupled making the U.S. the leading producer of wind energy with 25,176 plants.  Over the next five years 40,000 more turbines will be installed many of which will be replacing older with more efficient models.

Even in the face of a global economic crisis, wind companies are hopeful and intend to replace 45% of the outdated models by 2015.  Wind companies are aiming to produce 20% of our nation’s energy by 2030 all of which will be nearly pollutant free.  Although they are clearly planning long term they still bring gale force power to today’s world.  Their growth in 2008 channeled some 17.7 billion dollars into the economy and in the first quarter of 2009 alone prevented 52 million tons of carbon dioxide from ever reaching the atmosphere.  Wind power and its applications will certainly blow you over.

Iceland is a Hot Spot for Clean Energy

October 7th, 2009

iceland-geothermal-to-thaw-frozen-economy_1How much potential does geothermal energy, a cheap and renewable energy source, have to meet America’s clean energy needs?

According to NPR.org, geothermal energy could bring clean power hundreds of millions of homes and factories worldwide.

Oil sources are lessening and are growing increasingly more expensive. The people are pushing for greener alternatives.  With all this brouhaha about going green a few scientists peeped up about going “red”.  Their “red” solution is harnessing red hot magma for geothermal energy.  Geothermal energy is renewable and its factories produce almost zero greenhouse gas emissions and scientists in Iceland have successfully harnessed the power mother nature herself. Iceland sits on top of the schism of the Eurasian and North American tectonic plates along what is known as the Mid-Atlantic ridge.  This ridge feeds some thirty volcanoes magma as the two plates rip apart. Icelandic scientist use the old adage, “where there is smoke there is fire,” with respect to how they harness this awesome, primal energy source.  Surface volcanoes are like beacons indicating a “hot spot” or source of magma for the volcano.  Geologists then carefully drill deep wells over these hot spots.  Water and steam are launched forth, although not instantaneously, from the wells like man-made geysers.  The steam is then stripped of impurities and pumped into turbines that power generators that create electricity.  The hot water can be guided through pipes into radiators to heat homes and businesses.

95 percent of the homes in Iceland are already heated with geothermal energy, which is 5 times less expensive than oil heat.  Where might we see geothermal energy used in the US? Perhaps in Northern California, which has the world’s largest hot spots with their natural geysers. Beyond that, there are not enough hot spots in America to power the entire country as Iceland does.  Hippies need not break out their protest poster boards just yet although scientists at MIT estimate that geothermal energy could power up to 10 percent of the country.

Human Waste is Underrated

September 18th, 2009
Learn from Elmo, and turn you human waste into renewable energy.
Learn from Elmo, and turn your human waste into renewable energy.

What do you do with your human waste? Well, if you’re no fun you probably just flush it down the toilet, re-enacting what you think is “normal” from what you’ve learned from the rest of society. But now, Frank Sinton, a tech entrepreneur and founder of PMC BioTec, says it’s time to break this silly social norm, stick it to the man, and save some money.

America spends $5 billion a year dealing with sludge. Biosolids producers pay hundreds of dollars a ton to remove it, quickly filling landfills or other means of disposal, Sinton said on Sept. 15 at the AlwaysOn Going Green Conference in Sausalito, California. The scope of the globe’s sludge problem is mindboggling. Every year, cattle feedlots produce more than 150 million tons of animal waste; the U.S. and Europe together generate 40 million tons of sludge from sewage treatment; and food production waste weighs in at a staggering billion tons per year.

So what is Sinton going to do about it? He and PMC have invented a $2 million machine similar to a giant port-a-potty that takes in sludge, mixes it with bacteria, or renders the organic matter into methane gas, an energy source that can offset the high power requirements of many biosolid treatment facilities.

Farmer Invents Solar-Powered Lawn Mower

September 18th, 2009

091309r2aPeople are amazing these days. Last December, a 70-year old Indian woman gave birth to her first child. And now, just this past week, although not as physically impressive, a 70-year man from Colorado invented a line of solar-powered lawn equipment. So much for moving to that lakefront property in northern Florida.

Tom Lopez, the man behind the invention, lives on 120-acre Lone Hawk Farm just west of Hygiene, CO. With that much land to cover, it makes perfect sense to create a solar-powered lawn mower. And the best part? It wasn’t even that difficult to make.

“That’s the thing about this stuff — it’s not rocket science,” said Lopez, a 1962 University of Colorado-Boulder graduate with a degree in aerospace engineering. “It just uses standard technology.”

Lopez has built several mowers and tractors by himself, and is working with another company on mass-production. That’s good timing, because after being featured in a national magazine, Lopez is getting calls from all over the country.

“One local (customer), and the rest are nationwide,” Lopez said. “I’ve even got one in Alaska.

One Colorado farmer’s invention could go a long way to decreasing pollution all over the world.

Raise Your Hand If You Like Clean Water

August 11th, 2009

watcleaner-435x3001Oil spills, soda cans, and food wrappers constantly pollute our waters. So much so, that it makes me wonder if all those “No Dumping” signs have surreptitiously been changed to “Water: Your New Landfill.”

So how can we combat the growing problem of contaminated oceans, rivers and lakes? With robots, of course. Thanks to a new invention from Chinese industrial designer, Ye Yao, comes the WatCleaner, a device designed to automatically clean water.

The WatCleaner has detectors on the bottom that monitor water for pollution, everything from basic garbage to oil, and clean the water. Absorbent socks on the top of the WatCleaner absorb oil and cleanse it. Additionally, garbage is taken in and directed to a disintegrator- clean water is then sprayed through the top of the WatCleaner and returned to the water system.

And for those of you animal rights activists, don’t worry, the WatCleaner also detects fish in order to clean the water in their area.

Beyond just cleaning the water of contaminants, the WatCleaner is also set up to transmit water condition information to land based controllers and ask for help if it encounters conditions too polluted to handle alone.

The WatCleaner won an “Excellent Works” designation in the 2007 Japan Design Foundation International Design Competition.

A Trip to Oregon Gives Iraq New Priorities

August 11th, 2009

green1Iraq may have obligations that are more pressing than green building — but that has not stopped 19 of the country’s academics from touring Oregon for two weeks of seminars on the subject.

“There is a great interest in bringing sustainable concepts into our daily lives,” said Dalshad Ismael, director of engineering projects at the Kurdish Ministry of Higher Education, during a session on buildings of the future at a Portland community center this week.

“People may not understand it as such,” he added, “but they know we must protect what resources we have.”

Several participants said that the concept of sustainability is not new to Iraq, but years of warfare have meant that it is rarely put into practice.

The meetings could lead to what the visiting academics hope will be their country’s first major sustainability effort.

The trip was funded by the Michael Scott Mater Foundation, with assistance from Oregon State University, the University of Oregon and Portland State University as well as support from the United States Department of State. The 19 professors, lecturers and deans come mainly from schools of engineering in Iraq.
