Study Describes Wind Power Dependence on Atmospheric Stability

Posted by Ovidiu Sandru in Wind Power on January 19, 2012

Scientists from LLNL, University of Colorado at Boulder and the NREL have recently assessed the performance figures of a wind turbine producing energy on the East Coast, and found how power depends on atmospheric stability. “The dependence of power on stability is clear, regardless of whether time periods are segregated by three-dimensional turbulence, turbulence intensity [...]

EU Planning on Building An European Renewable Energy "Supergrid"

Posted by Ovidiu Sandru in Energy news on January 5, 2010

The first electricity grid dedicated to renewable power becomes a political reality this month, because nine European countries draw up plans to link their clean energy projects around the North Sea.

Japan Plans to Deploy Space-Based Solar Power Station

Posted by Ovidiu Sandru in Solar Power on November 10, 2009

JAXA, the Japan Aerospace Exploration Agency, wants to compete with the United States’ PG&E project for collecting solar power from outer space and beam it on Earth through clusters of lasers and microwaves.

Remarkable Lifetime Results for EV Batteries

Posted by Cristi in Energy Storage on June 10, 2009

Scientists from Southern California Edison (SCE) have developed an tested for two and a half years a lithium-ion battery sub-pack with very encouraging results. The battery tested survived 180,000miles with no significant deterioration.

Samsung Says Water Powered Cell Phone Ready by 2010

Posted by Ovidiu Sandru in Green Electronics on April 17, 2008

Water powered cell phones are yet another cool invention from Samsung. After they did break many European and American markets, they plan to knock out those solar power fanatics, by using water as a power source. Yes, you heard right.

Hydrogen Cheaper Than Gasoline: Thanks To Nanoparticles

Posted by Ovidiu Sandru in Hydrogen Power on February 29, 2008

QuantumSphere Inc. says it has perfected the manufacture of highly reactive catalytic nanoparticle coatings that could up the efficiency of electrolysis, the technique that generates hydrogen from water. Moreover, the coatings could also eliminate the need for expensive metals like platinum in hydrogen fuel cells. The coatings can be used to retrofit existing electrolysers to [...]

Moth Eyes Inspiration For New Generation Solar Cells

Posted by Ovidiu Sandru in New Inventions, Solar Power on February 26, 2008

Most moth eyes are made up of adjacent hexagonal sectors. Each sector is filled with thousands of orderly rows of miniscule bumps, or nipple-like protrusions. Though formed so perfectly they appear almost manufactured, each protrusion measures less than 300 nanometers, or 300 billionths of a meter – a size that renders them invisible to all [...]

Bluenergy: Wind and Solar Power in One Piece

Posted by Ovidiu Sandru in Solar Power, Wind Power on February 26, 2008

The BSWT is a vertical wind turbine based on sailing engineering. The wind rotor is rotated by two spiral-formed vanes. For best performance, these vanes are covered in solar cells, so that sun and wind produce electricity as one element. The BSWT installation costs relatively little, produces no noise or significant shadowing, can be easily [...]

A Soda Can Powered Solar Garage Heater

Posted by Ovidiu Sandru in Solar Power on February 24, 2008

I found out the ingenuity of some people exceeds “common sense” and their inventions are really helpful to humanity. Not on large scale, but for those tech-guys who do nothing but sit all day long in their garages and invent crazy things nobody would have imagined. Most of these inventions stay there, in the respective [...]

Nano Fibers Will Power Your iPod

Posted by Ovidiu Sandru in Green Electronics, New Inventions on February 17, 2008

Have your ever seen those self-powered mechanical watches, those who charge themselves from your hand’s movement? They have one half of a heavier metal disc spinning around an axis. That movement rotates some wheels, who finally rotate the watch spring. However, that is not our article’s subject. Our article talks about some newer discovery: some [...]

The Solar Table That Powers Your Laptop!

Posted by Ovidiu Sandru in New Inventions, Solar Power on February 12, 2008

Sudia Design Labs, located in New York, has created a table that you can put out in the sun. What for? To charge it, of course! It has a big solar panel on top of it, is made 90% from recyclable materials and weights 20kg. You can charge your laptop, small appliances, etc. Its 64 [...]

UltraBattery – the image for future electric power

Posted by Ovidiu Sandru in Energy Storage on February 11, 2008

Don’t you know? I didn’t either. But the idea is not at all complicated. It’s a lead acid battery combined with a supercapacitor. A supercapacitor is simply a capacitor that can achieve greater states of charge and can output a greater quantity of energy in a shorter time. Power=Energy/Time. The shorter the time, the greater [...]

Nano Flakes: more power from the Sun

Posted by Ovidiu Sandru in Solar Power on February 10, 2008

Dr. Martin Aagesen, a researcher at the University of Copenhagen and director of SunFlake Inc. is currently developing a technology called “Nano Flakes”. Nano Flakes are semiconductors with a perfect crystalline structure, and they can absorb about 30% of the solar energy applied to them. “I discovered a perfect crystalline structure. That is a very [...]

Do you agree to genetically mutate trees for ethanol production?

Posted by Ovidiu Sandru in Ethanol on February 10, 2008

Here we go again. A few weeks ago I wrote an article about some scientists inventing a way to modify the DNA of a bacteria to produce hydrogen. Ok, I didn’t fully agree with that – considering that bacteria is an extremely small microorganism, and you don’t know what ecological disaster it might produce when [...]

Solar Islands Bring Electricity From Desert and Sea

Posted by Ovidiu Sandru in Solar Power on February 6, 2008

CSEM, the Swiss Center for Electronics and Microtechnology, has signed a contract with the government of the Emirate of Ras Al-Khaimah (RAK) in the United Arab Emirates (UAE), to develop a prototype of a “Solar Island”. The aim of the project is to validate a concept for the large-scale transformation of solar energy into hydrogen [...]
