Previous news were saying that the Obama administration doesn’t have any plans of installing solar panels on the White House. Not even a month has passed, and a representative of the White House in Washington, DC says solar panels will be installed on the White House in order to impulse Americans to adopt green energy.
Tony Danger Coiro, a student at Purdue University, has recently created a zero-emission electric motorcycle that is powered by solar energy. The motorcycle, which initially cost about $50, is a transformed version of an old 1978 Suzuki.
A group of researchers at the Sandia National Laboratories found a new way to predict and prepare for fluctuations in electricity generation due to changes in weather – cold, heat, clouds and airborne dust.
Light behaves differently in macro- and nano- scale environments, and this could be a starting point for those researchers who want to improve the solar cells’ efficiency. It was a starting point for some Stanford engineers, who found out that light ricocheting inside an ultra-thin polymer film solar cell behaves differently than if the film wasn’t so thin. The difference is enormous.
Three South Florida schools (Deerfield Beach Middle School, Mandarin Lakes K-8 Academy in Homestead and SunCoast Community High School in Riviera Beach) have received solar panels from FPL Group Foundation. This way the schools will start saving money and teaching students about renewable energy.
I’ve been hearing at least two versions of how we should construct an orbital power station, that would harness the Sun’s power and transmit it through lasers or microwaves to Earth. Those concepts, along with classic solar and wind power fade when compared to this one.
The US military’s DARPA has signed an $89 million deal with Boeing for the development of a solar powered, unmanned aircraft that could stay aloft for more than five years. Of course, the aircraft would be used in espionage purposes, but the concept is also a testing ground for civilian purposes.
Solar cells currently used are mostly bulky and made from silicon and other non-recyclable materials, hence they’re not as green as they should be. Mimicking nature might be a solution to this problem. More exactly, North Carolina State University researchers have prototyped a water-based solar cell, mimicking the functioning of a leaf, to produce electricity.
Verve Energy in collaboration with BP Solar are planning to build Australia’s largest ever grid-connected solar power plant. The photovoltaic power plant is expected to generate about 10MW of clean energy and according to the two companies, it will be built in Geraldton, Western Australia.
University of Florida researchers have invented spray-on polymers that can reflect or transmit any color, and can be applied to glass or plastics as well. “That’s what this newest paper is about, but we’ve also developed polymer coatings for all the other colors of the spectrum,” said John Reynolds, a scientist at the University of Florida who led a team that developed the clear-to-black polymers.
At the beginning of this month, the European division of Sanyo has officially released its new enhanced HIT solar panel. Dubbed HIT-N235SE10, the new 235 watt solar panel has an energy-efficiency of 21.1%, improving the performance in limited space installations and offering more power generation per square meter.
Doug Natelson and graduate student Dan Ward, from Rice University, have discovered how to make a light-harvesting antenna from two gold tips separated by a gap only a few nanometers wide. As light source they used a laser, whose rays, once trapped in the gold tips, get concentrated into a tiny space, increasing the light intensity in the gap by a thousand times.
Windrex, an expert cooperation in the fields of alternative energy will unveil its new wind-solar hybrid street lighting at the Renewable Energy Expo 2010 in Seoul, Korea.
The UK environmental group Carbon Trust and Cambridge University’s Cavendish Laboratory have jointly formed a new company called Eight19 concentrating on the development of new organic photovoltaic (PV) technology that could make the installation of solar cells cheaper and easier.
A recent study, conducted by the Rochester Institute of Technology, reveals that the total energy needed to make organic solar cells is less than the one needed to make inorganic solar cells.
