Mag-Wind New Wind Turbine [Video]

[Ed. note - video removed by owner]

Jay Leno’s all about the green tech, I mean, his garage is running on wind and solar, and it powers approximately two-thirds of the place.  So recently, he just put up this video demonstrating a new technology for rooftop wind applications.  The Mag-Wind turbine is made by Enviro Energies and both Jay Leno and Ed Begley Jr. have their own versions on order.  Naturally, Leno was excited to point out that his turbine will be bigger than Begley’s, but in addition to that, you’ll get an idea from the video how interesting the technology actually is.  It’s built using magnetic levitation technology that reduces friction, noise, vibration, and energy loss.  Some other interesting aspects of the Mag-Wind System include:

Inventor Creates Net-Zero Energy Island

North Dumpling Island

Dean Kamen is a well-known entrepreneur and inventor of various technologies, including the Segway, Project Slingshot, and a hybrid electrical car with a Stirling engine.  He’s also trying to establish an independent, net-zero energy island off the coast of Connecticut.  The three-acre private island is called North Dumpling, and if granted his wishes, it would have its own constitution, flag, and national anthem.  Kamen’s attempts at secession haven’t been successful yet, but that’s no surprise given the South wasn’t able to do it either.  He has found success installing LEDs and saving energy, though.

Vatican Gets Serious with Solar

Solarpaulvihall

Maybe Samsø started a trend in becoming a net exporter of renewable energy because it appears that the Vatican is thinking about doing something similar.  The curvaceous roof of Paul VI Audience Hall, a building that's located right by the famous St. Peter's Basilica, has been topped with 2,400 photovoltaic panels to source energy for lighting, heat, and air conditioning.

Thoughts on Al Gore's Five-Part Plan to Repower America

Five-Part Plan to Repower America - Al Gore

I’ve always been kind of irked by the fact that President Reagan, after having the White House’s leaky roof fixed, never replaced the solar hot water panels installed by President Carter.  But it’s hard to judge him because I was barely crawling at the time — I have no idea what was going on in the collective conscious of that generation.  I mean, Al Gore mentions in Sunday’s Op-Ed in the NY Times that President Nixon established Project Independence 35 years ago with a goal to, in seven years time, develop the potential to meet our country’s energy needs without having to rely on any foreign energy sources.  Yet, that never happened and Reagan’s act, the way I see it, symbolically shut the door on the possibility of American energy self-reliance.  At least for the time being.

Solyndra’s Totally Tubular Solar Cells

Solyndra

Solyndra just released new details of their proprietary solar technology printed with a copper, indium, gallium, and selenium (CIGS) mixture on glass tubes.  Solyndra also announced over $1.2 billion in orders and a successful installation using the cylindrical solar tubes on the roof of their corporate headquarters.  With the glass tube design and easy installation, the company expects to provide commercial customers with higher electricity output per rooftop and significantly reduced installation costs.

Air Breeze Off-Grid Wind Turbine Improves Upon Popular Air-X

Air Breeze by Southwest Windpower

If you’ve heard of the popular Skystream 3.7 by Southwest Windpower, then you’re probably familiar with their smaller wind turbine called Air-X.  Air-X was introduced in ~2001 and flew off shelves, selling over 100,000 units.  Building on the success of Air-X, Southwest Windpower recently released Air Breeze, its next iteration of the successful small wind generator.  I first noticed an ad for Air Breeze in Natural Home Magazine last September and have since seen news of it popping up everywhere.  Air Breeze was engineered to be quieter, more efficient, and more effective at lower wind speeds …
