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

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.

The Key to a Battery-Powered House

August 4th, 2009

house-battery-470-0709Imagine a life where you would never have to deal with PG&E ever again. Sounds good, right? Soon it can actually become reality.

Without a way to store their power, no number of solar panels will free a home from the electrical grid. Until now. Researchers at Utah-based Ceramatec have developed a new battery that can be scaled up to store 20 kilowatt-hours—enough to power an average home for most of a day.

An easy sell for solar users, but it could also allow the grid to stockpile energy during less expensive off-peak hours. The new battery runs on sodium-sulfur—a composition that typically operates at greater than 600 F.

“Sodium-sulfur is more energetic than lead-acid, so if you can somehow get it to a lower temperature, it would be valuable for residential use,” Ralph Brodd, an independent energy conversion consultant, says. Ceramatec’s new battery runs at less than 200 F.

Ceramatec says that batteries will be ready for market testing in 2011, and will sell for about $2000.

The Revolutionary Trashcan

July 28th, 2009

trashxHave you ever been too lazy to take out the trash so you just squish it down? Not wanting to go outside, you go to great lengths to squeeze the pizza box, milk carton and moldy leftovers all into that brimming under-the-sink waste receptacle.

Well, the city of Philadelphia has found a way to beat the system – as well as saving money and helping the environment.  The cheesesteak haven has replaced 700 public trash containers downtown with 500 high-tech compactors called BigBelly’s, which use solar power to condense trash, cutting collection trips by 75%.

Facing a $1.4 billion, five-year budget deficit, the city estimates it will save $875,000 a year with the compactors, bought with state grant money.

The BigBelly is powered by light, but it does not need direct light, said Richard Kennelly, VP of Marketing for BigBelly Solar, which is based in Needham, Mass. When trash gets to the top of the bin, it breaks an electronic beam that triggers a motor that pushes it down. As trash gets more densely packed, the machine senses the resistance and changes a light on the front of the bin from green to yellow.

The cans also have a wireless monitoring system that notifies the city when they’re full. In addition, the city is introducing curbside recycling containers next to many of the compactors.

Milan Greenlights Construction of World’s Largest Solar Rooftop

July 28th, 2009

1789_fiera-milanoMilan, a city renowned as one of the world’s capitals of design and fashion, recently announced a blueprint for the planet’s largest solar rooftop solar array intended for its Milano Fiera trade fair facility.

Due for completion next year, the massive photovoltaic system will cover 2.9 million square feet and carry a peak capacity of 18 megawatts – enough to power a small city.

With the World Expo 2015 on the way, Milan is kicking its architectural endeavors up into high gear with a number of new major developments and revitalization projects. The city has already enlisted high profile designers to create the facility such as Zaha Hadid, Norman Foster, Arata Isozaki, and Daniel Libeskind.

While no definite start date has been set for construction of the solar array, bids have already been submitted, and the array is anticipated to be completed by the end of 2010.

A Groundbreaking Flight Around the World

July 28th, 2009

solarimpulse2Swiss adventurer Bertrand Piccard better check the weather report before liftoff if he wants his latest quest to be a success. The explorer is constructing a solar-powered plane to fly around the world in an effort to support sustainable development and demonstrate what renewable energy can achieve.

Solar Impulse [the plane] will promote the idea of a new aviation era using cleaner planes powered by the almost infinite energy of the Sun rather than the dirty, finite reserves of fossil fuels,” says Bertrand Piccard.

“Although in its present design the craft will never be able to carry many passengers we believe that Solar Impulse can spark awareness about the technologies that can make sustainable development possible.”

Piccard hopes to start his round-the-world journey in 2010, barring no setbacks. The single-pilot Solar Impulse will be flown by three pilots flying in shifts: Bertrand Piccard, President and initiator of the project; Brian Jones, responsible for the sustainable development program; and André Borschberg from Switzerland, the Solar Impulse Chief Executive Officer.

The round the world trip will take place in five stages, each of which will last three to five days. It will fly from west to east and between 10° and 30° north of the Equator to take advantage of the prevailing winds and sunlight.

The Surprising Benefits of Seaweed

July 13th, 2009

algae-fuelAlgae. It’s the gooey, yucky stuff that makes you jump as if a shark is about to attack when it innocently brushes against your foot while you play about in the ocean. But recently, Italian scientists have proven these simple, autotrophic organisms can be turned into a resource.

Italy recently announced a 200 million euro eco-friendly project to harvest the prolific seaweed that lines Venice’s canals and transform it into emissions-free energy. The idea is to set up a power plant fueled by algae, the first facility of its kind in Italy. The plant, to be built in collaboration with renewable energy services company Enalg, will be operative in two years and produce 40 megawatts of electricity, equivalent to half of the energy required by the entire city center of Venice.

“Venice could represent the beginning of a global revolution of energy and renewable resources. Our goals are to achieve the energetic self-sufficiency for the seaport and to reduce CO2 emissions, including those one produced by the docked ships”, says the president of the seaport of Venice Authority, Paolo Costa.

Urine: Fuel of the Future?

July 8th, 2009

urine-1
The Royal Society of Chemistry reports that US researchers have developed an efficient way of producing hydrogen from urine – a feat that could not only fuel the cars of the future, but could also help clean up municipal wastewater.

Using hydrogen to power cars has become an increasingly attractive transportation fuel, as the only emission produced is water – but a major stumbling block is the lack of a cheap, renewable source of the fuel. Gerardine Botte of Ohio University may now have found the answer, using an electrolytic approach to produce hydrogen from urine – the most abundant waste on Earth – at a fraction of the cost of producing hydrogen from water.
