Harnessing waste heat to produce electricity
By Darren Quick
21:13 November 19, 2009 PST
That heat emanating from your computer as you sit reading this article amounts to nothing more than wasted energy. And your computer is not alone. More than half of the energy consumed worldwide is wasted, most of it in the form of excess heat. But new research at the Massachusetts Institute of Technology (MIT) indicates it might be possible to harvest much of the wasted heat produced by everything from computer processors to car engines and electric powerplants, and convert it into usable electricity. This kind of waste-energy harvesting might lead to mobile phones with double the talk time, laptop computers that can operate twice as long before needing to be plugged in to mains power, or energy plants that produce more electricity for a given amount of fuel.

The solar-powered school on stilts
By Jeff Salton
01:19 November 19, 2009 PST
It's almost as good as going to school in a treehouse. The recently opened Elleray Preparatory School in the Lake District National Park has three class pods standing on stilts connected by a center platform made from recycled materials, such as plastic milk bottles and wood shavings. Nestled amongst the trees, the complex is built to have a low environmental impact and therefore makes excellent use of solar power, rainwater collection, and has an energy-efficient heat pump.

Citroen C-ZERO - no local emissions, no fuel consumption, no engine noise
By Jeff Salton
19:41 November 15, 2009 PST
After building more than 5,500 electric vehicles, Citroen is calling on its experience in the field to deliver a “triple zero” car - zero fuel consumption, zero CO2 emission at the tailpipe and zero engine noise. The C-ZERO (what else could they call it) is a full electric city car powered by a permanent magnet synchronous motor delivering 47kW or 64bhp EEC from 3,000 to 6,000rpm. Citroen says the automatic vehicle will have a top speed of 130kph (80mph), acceleration from 0-100kph (0-62mph) in 15 seconds and 60-90kph (37-56mph) in six seconds. Between charges, the vehicles is expected to achieve a range of around 130km (80 miles). Read More
New solar storage solution could be the key to home-brewed electricity
By Darren Quick
22:28 November 4, 2009 PST
Reports of new developments in the area of solar power are an almost daily event here at Gizmag. The main focus of research seems to be on improving the efficiency of solar cells, but others are working at developing an inexpensive method of locally storing the energy generated by solar systems. Because society relies on a continuous energy supply and solar energy is diurnal, storage systems are integral to what some see as an inevitable move towards the era of “personalized solar energy”, in which the focus of electricity production shifts from huge central generating stations to individuals in their own homes and communities.

By Paul Ridden
17:50 November 3, 2009 PST
Plans for the installation of wind farms the world over are being delayed or abandoned due to objections from the aviation community or air defense interests. The problem is that when it comes to low flying aircraft or wind turbines, conventional radar has a bit of an identity crisis - not being able to tell the difference. Recent tests in the UK of "stealth" turbine technology could provide a solution. Read More

4x, 8x, huh? How much power do Lithium batteries actually have?
21:36 October 18, 2009 PDT
These days, if you go looking for batteries you're likely to find a range of products with some fairly bold claims on their packaging. Standard AA alkaline batteries are the least expensive and have been around for decades, but now there's a bunch of other choices for single use batteries that are marketed as better choices for "digital" devices than the "copper top" or store branded staples we've used for years. Among the newest of these is Energizer's Advanced Lithium and Ultimate Lithium single use batteries. Read More
Is there something in the hair? The tale of a solar cell made with human hair
By Paul Ridden
11:37 October 15, 2009 PDT
Debate is good. Debate is healthy. Debate is currently raging after an article recently appeared on the UK's Daily Mail website announcing a revolutionary solar cell that's made using human hair. A group of teenage students from Nepal claim to have replaced expensive doped silicon used in conventional solar panels with cheap and readily available human hair to produce a cell capable of generating 9V (18W) of electricity. Curiosity got the better of Gizmag's Paul Ridden, who contacted one of the team to find out more. Read More

Trashing existing fuel sources could cut global emissions by 80%
By Darren Quick
01:03 September 30, 2009 PDT
If there’s one thing there seems to be an endless supply of, it's garbage. The idea of turning the trash that currently ends up in landfill into a fuel to combat the growing energy crisis and tackle carbon emissions isn’t new. Companies like Waste2tricity in the UK are already looking to convert waste from business and industry into clean electricity. Now scientists in Singapore and Switzerland have added credence to the idea, saying that replacing gasoline with biofuel derived from processed waste biomass could cut global emissions by 80%.

Color matters: GreenSun Energy colored solar technology
By Paul Ridden
17:22 September 24, 2009 PDT
One of the most common ways to turn the sun's energy into electricity is by persuading silicon to give up some of its electrons. But it's also quite expensive, so any innovation that helps reduce the cost of solar cell production is welcome. Researchers in Israel have come up with a cell that uses only 20% of the silicon in a standard cell yet yields similar amounts of electricity. It does this by diffusing any light that falls on its surface and sends it off to photovoltaic collector strips on each of its sides. And it doesn't even need bright sunlight to operate. Read More

Plan to turn rooftops, walls and windows into cheap solar cells
By Jeff Salton
19:23 August 25, 2009 PDT
Cheaper solar cells – roughly one-tenth the cost of current day prices – could be available within three to five years thanks to a manufacturing procedure that uses nanoparticle ‘inks’ to print them like newspaper or to spray-paint them onto the sides of buildings or rooftops. Even windows could become solar cells thanks to the semi-transparent inks. 'Painting' solar cells on buildings has been an idea in the making for some time – Gizmag investigated the possibilities of 'solar paint' in 2008. Read More
