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…”

Samsung Invests CAN $7B in Ontario Wind and Solar

January 24th, 2010

From Renewable Energy World

This week, a consortium led by Samsung C&T Corporation and the Korea Electric Power Corporation (KEPCO) announced that it plans to invest CAN $7 billion to generate 2,500 megawatts of wind and solar power in Ontario, Canada.

According to the terms of the green energy investment agreement, Samsung C&T and KEPCO will establish and operate a series of wind and solar power clusters over the next 20 years. The clusters, which will be built in several locations throughout the province, will eventually include wind turbines that will generate up to 2,000 MW as well as solar power facilities that will generate up to 500 MW.

The entire project will have a combined power-generating capacity of 2.5 GW by 2016, producing energy equivalent to four per cent of Ontario`s total electricity consumption.

Europe Shows the Way to Energy-Efficient Design

January 12th, 2010

From the Matter Network:

After the EU signed Kyoto, requiring it to reduce carbon emissions 8% below 1990 levels by 2012, many products and design changed there, diverging from US standards. Cars, for example, became smaller, lighter; and more fuel efficient. Even US automakers not known for efficiency make 62 MPG cars for Europe. Germany and Spain introduced Feed-in Tariffs that paid homeowners to make solar power on their roofs.But most interestingly, for Americans now considering energy efficient retrofits with a new “Cash for Caulkers” program being considered, a whole new industry was created by the need to supply new energy efficient building innovations.

Malawian High School Drop-Out Electrifies Village

October 11th, 2009

Picture this. You’re a 14-year-old boy from Africa and you’ve just got kicked out of school because you couldn’t pay $80 in school fees. What do you do?

Considering you don’t have a lot of money to spend, and your country severely lacks natural resources, you don’t have a lot of options. But here’s just a guess: you most likely won’t end up inventing a windmill that powers your entire village.

But that’s exactly what William Kamkwamba did.

After getting booted from the classroom, Kamkwamba headed straight for the library, where a book with photographs of windmills caught his eye.

“I thought, this thing exists in this book, it means someone else managed to build this machine,” he said.

Armed with the book, the then-14-year-old taught himself to build windmills. He scoured through junkyards for items, including bicycle parts, plastic pipes, tractor fans and car batteries. For the tower, he collected wood from blue-gum trees.

“Everyone laughed at me when I told them I was building a windmill. They thought I was crazy,” he said. “Then I started telling them I was just playing with the parts. That sounded more normal.”

That was 2002. Now, he has five windmills, the tallest standing 37 feet.

The windmills generate electricity and pump water in his hometown, north of the capital, Lilongwe. Neighbors regularly trek across the dusty footpaths to his house to charge their cellphones. Others stop by to listen to Malawian reggae music blaring from a radio.

This just goes to show that as long you have perseverance and passion, truly anything is possible.

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.

The Army Goes Green, Say What?

August 4th, 2009

070622-f-0782r-004Isn’t it great when you selfishly do something and it turns out to be good for everybody? The U.S. Army can now add itself to that list.

When the Army announced they were going to build a 500 megawatt solar thermal plant in the California desert, it was hard to believe they were just trying to help the environment. And with good reason.  As altruistic as the Army is, it usually isn’t well known for its philanthropy. But if it helps the planet, I won’t stop them from building it.

As it turns out, sustainable energy is safer, suggests Dr. Kevin Geiss, the program director for the project. The Army hired private developers, Clark Enterprises and a Spanish company called Acciona, that will build this massive solar plant at Ft. Irwin, California.

Right now, like many military bases, most of its energy comes from diesel generators—with long, vulnerable lines back to the fuel source. Screw the green movement, solar just makes sense.

The solar plant at Ft. Irwin will require at least 1.5 billion dollars total, and should be ready to crank electrons by 2022. A hefty price, yes, but there is the potential to earn much of it back. Located conveniently right next to high capacity transmission lines, the army can then sell most of the excess energy to southern California; and since Ft. Irwin only needs 35 megawatts at its peak, that leaves 465 to shed.

So what could be next on the irony scale? The CEO of GM driving to work in a Prius?

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.
