Tiny Hybrid Device Harvests Both Solar and Thermal Energy

Posted on December 13, 2010 by Benny Hollywood| Comments Off on Tiny Hybrid Device Harvests Both Solar and Thermal Energy

Image via Fujitsu Constantly fascinating is the area of harvesting energy from our own bodies to power devices. A steady stream of concepts from designers and prototypes from labs keeps us entertained, though few are really viable Fujitsu hopes that its latest breakthrough in harvesting energy from both light and heat could be the next big thing for microenergy harvesting via wearable technology. Without the need for electrical wiring or battery replacements, the company hopes it could be part of commercial products by 2015. … Read the full story on TreeHugger

China to Hit 500 GW of Renewable Power by 2020

Posted on December 6, 2010 by Benny Hollywood| Comments Off on China to Hit 500 GW of Renewable Power by 2020

Photo: 林 慕尧 / Chris Lim , Wikimedia, CC Energy hawks — hell, all of us, really — have no doubt gotten a little tired of hearing about how much investment China is dumping into clean energy compared to the United States. Yes, we are severely lagging in the renewable sector, and yes, China is poised to eat our lunch in solar and wind — China has just set a new goal to get 500 GW of renewable power on the grid by 2020. No, we’re nowhere near that number — and we certainly won’t be if we continue on our current trajectory. But there’s still a lot to learn from Ch… Read the full story on TreeHugger

We Could Have 10 MW Wind Turbines by 2011 and 15 MW Turbines by 2020

Posted on December 6, 2010 by Benny Hollywood| Comments Off on We Could Have 10 MW Wind Turbines by 2011 and 15 MW Turbines by 2020

Photo: Enercon E-126 , currently the biggest wind turbine Winds of Change Wind turbines have been getting bigger and more powerful for a while. It wasn’t that long ago that 1.5-megawatt turbines were considered impressive, but now we have the Enercon E-126 (pictured above and below), currently the biggest wind turbine and able to generate 7 megawatts. But even that isn’t even close to reaching the physical limits of what we can build; The Norwegian company Sway will build a 533-feet, 10-megawatt giant by 2011 (follow… Read the full story on TreeHugger

Eight Reasons Distributed Power Generation Is Superior To Central Power Station Expansion

Posted on December 2, 2010 by Benny Hollywood| Comments Off on Eight Reasons Distributed Power Generation Is Superior To Central Power Station Expansion

Four Seasons Hotel Philadelphia installed three Capstone C65 ICHP MicroTurbines® – a form of distributed power generation. Image credit: Capstone Turbine Now that I have succeeded in disturbing a number of engineers and environmentalists, while admitting the difficulty of even defining distributed power (see What Is Distributed Power Generation? for details), it is time to lay out what makes distributed power generation (DP) superior to expanding central power ge… Read the full story on TreeHugger

Honeywell Windtronics Turbine Is Giant Generator

Posted on November 30, 2010 by Benny Hollywood| Comments Off on Honeywell Windtronics Turbine Is Giant Generator

Image credit Lloyd Alter It was hard to find anyone to speak to at Greenbuild about the odd looking Honeywell Windtronics turbine; it was a busy booth. But I got to see it again at the Cottage Life Show in Toronto and it is actually very interesting; instead of the usual design where the blades turn a shaft which is connected to a generator, here the whole thing is a generator, with magnets at the tips of the blade whizzing past stator coils in the ring on the perimeter. … Read the full story on TreeHugger

Steven Chu: China Giving U.S. a Clean Technology "Sputnik Moment"

Posted on November 30, 2010 by Benny Hollywood| Comments Off on Steven Chu: China Giving U.S. a Clean Technology "Sputnik Moment"

Photos: Wikipedia, Public domain. Investing Now for a Better Future In a speech at the National Press Club, U.S. Energy Secretary Steven Chu made the case for more R&D in the U.S., especially in the energy sector (“the 2010 federal budget is $3.6 trillion, of which 0.14 percent went for research and development related to energy”). Dr. Chu explains why this is essential for both economic development and to meet environmental challenges, and he compares China’s progress in clean technologies and energy to the wake up call that was the launch of the Sputnik satellite by the Soviet Union….

Spectrolab is Starting Mass-Production of 39.2% Efficient Concentrating Solar Cell

Posted on November 24, 2010 by Benny Hollywood| Comments Off on Spectrolab is Starting Mass-Production of 39.2% Efficient Concentrating Solar Cell

Image: Spectrolab Evolutionary, Not Revolutionary Spectrolab , a subsidiary of Boeing, has announced that it is starting mass-production of a very efficient concentrating solar cell, the C3MJ+ (the datasheet above is for the C3MJ, the “plus” version is a newer, slightly more efficient model). With an efficiency at converting sunlight into electricity of 39.2%, this cell would be the most efficient on the market. “Last year we set a new world record for efficiency with a test cell that peaked at 41.6 percent.

iSuppli Forecasts 15.8GW of Solar PV in 2010, 19.3GW in 2011

Posted on November 16, 2010 by Benny Hollywood| Comments Off on iSuppli Forecasts 15.8GW of Solar PV in 2010, 19.3GW in 2011

Photo: Flickr , CC Solid Solar Growth Market reserach firm iSuppli’s latest forecast for the solar power industry is out, and the predictions for total installed capacity in 2010 and 2011 are pretty positive. The forecast for 2010 was increased from 14.2 gigawatts (GW) to 15.8 GW, in good part thanks to stronger than expected demand in Germany. If accurate, this would represent 118.7% growth from 7.2GW in 2009! But sadly, 2011 won’t see another 100%+ increase; the forecast for that year is of 19.3 GW, down a bit from the pre… Read the full story on TreeHugger
