Lasers Take Science One Step Toward Unlimited Clean Energy

February 8th, 2010 No comments »

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 1 comment »

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…”

From Cleantech Blog

The U.S. wind industry broke all previous records by installing 9,922 MW installed last year. This expanded the nation’s wind fleet by 39% and bring total wind power generating capacity in the U.S to over 35,000 MW. The five-year average annual growth rate for the industry is also 39%. U.S. wind projects today generate enough to power the equivalent of 9.7 million homes, protecting consumers from fuel price volatility and strengthening our energy security.

Samsung Invests CAN $7B in Ontario Wind and Solar

January 24th, 2010 1 comment »

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.

Obama Pursuing Climate and Clean Energy Targets: Year 1

January 12th, 2010 No comments »

6820_NpAdvHoverPresident-Elect Barack Obama’s transition, the Center for American Progress proposed a 10-point clean-energy agenda for the president and Congress that would speed the economic transformation to a clean energy economy.

A review of these items today finds that all were adopted or are working their way through the process. This is a startling achievement amidst the worst economy in 70 years, two wars, and an opposition party disinterested in cooperation. President Obama did much of what he promised, and he can do more in 2010 by cajoling Congress to do its part.

Europe Shows the Way to Energy-Efficient Design

January 12th, 2010 No comments »

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. Energy efficient glass.

GreenBeat: Al Gore says Smart Grid part of ‘the single largest solution’ to climate change

November 23rd, 2009 No comments »

al-goreNobel Prize winner and former vice president Al Gore gave a wide-ranging, passionate talk at VentureBeat’s GreenBeat 2009 conference yesterday in San Mateo about combating global warming. We already liveblogged Gore’s talk, but for folks who don’t want to read the blow-by-blow description, here’s a summary.

Perhaps the most significant point: That energy efficiency is “the single largest solution to the climate crisis,” and the Smart Grid will “play a crucial role” in achieving that efficiency.

Kyoto Protocol: An Anti-Climate-Tic Ending

October 19th, 2009 No comments »

titlephotoAs 2012 draws closer and closer, so too does the end of the prestigious Kyoto protocol.

The Kyoto protocol is a global initiative aimed at stabilization of greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic interference with the climate system.  Which as most would agree is a great thing.

Although according to NPR, drafting a new agreement in the near future seems unlikely.  The reason for this is strong opposition from the United States Congress.  Although President Clinton signed the original pact, the U.S. refused to ratify the original agreement and is slowing the creation of a new draft because the original pact did not require any action from developing countries like China, which is the world’s largest greenhouse gas emitter.

Both the Bush and the Obama administration felt that this was a fatal flaw in the protocol. There has been little progress but not for lack of effort.  In an interview between NPR and European Commission Vice President, Margot Wallstrom, she said that it has been very difficult negotiating a treaty that the U.S would agree to and that all parties involved would rather be on track to a solution.

Hopefully these issues will be worked through in December when world leaders meet in Copenhagen to discuss next steps.

The Fashionable Way to Fight the Flu

October 11th, 2009 No comments »

Imagine a world way off in the future, where all you had to do to avoid swine flu was wear a special suit, completely indistinguishable from your typical business attire.  What year do you think that would be available? 2050? 2100? 2500?

How about this week.

A Japanese company, Haruyama Trading Co., has developed a suit that it claims protects the wearer from the deadly H1N1 strain of influenza.

The suit is coated with the chemical titanium dioxide, which reacts to light to break down and kill the virus when it comes into contact with it, according to company spokesperson Junko Hirohata. The chemical is a common ingredient in toothpaste and cosmetics.

The company has produced 50,000 of the suits and will start selling them on Thursday, for about 365 GBP. The company said it spent a year developing the suit, which retains its properties even after being washed numerous times.

Japan has been gripped by swine flu fear since the global outbreak began a year ago, with the World Health Organization confirming more than 340,000 cases worldwide and around 4,100 deaths.

And you thought there wouldn’t be a stylish way to thwart swine flu.

Malawian High School Drop-Out Electrifies Village

October 11th, 2009 1 comment »

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.
