The first commercially available fuel cell device charger is here! (Well, technically it’s only “here” if you’re reading this in Japan, but that should soon change). Toshiba’s Dynario charger packs fuel cell technology into a portable package that can provide instant power to a dead mobile phone or other gadget, completely off the grid.
I’ve been testing a device that just been introduced called the PowerGorilla. It’s a portable power pack that acts an emergency back-up charger for your laptop computer other other electronic gadgets. The battery inside the PowerGorilla is a lithium-ion and weighs just 631 grams (1.4 pounds). The charger will give you an extra 2-5 hours… [Continue Reading]
Most cell phones don’t even come close to being green — their chargers are energy inefficient, they contain hazardous chemicals, and they not are designed for upgrading or easy recycling. Recently though, some the big players in the field like Nokia and Sony Ericsson are making moves towards green design. As far as assessing which… [Continue Reading]
We’ve seen prototypes for solar-powered cell phones, but now a Chinese company claims to have developed the world’s first commercially available solar-powered cellphone. The company says a scale-like solar panel on the top side of the phone can also be recharged by light from artificial sources. It can provide 40 minutes of talk-time after sitting… [Continue Reading]
Science Daily reports that British scientists have developed a “biofuel cell” that generates electricity from air spike with small amounts of hydrogen. These cells are an inexpensive, renewable alternative to “fuel cells” that have been closely associated with the “hydrogen economy”. At a recent meeting of the American Chemical Society, Fraser Armstrong, described how his… [Continue Reading]
Here is a model race car that runs on hydrogen produced by a small solar cell. The car uses a real fuel cell and its own on-board hydrogen storage system. To create free hydrogen fuel, you just add water to the stations tank. Fueling is animated by a special blue light display. The car will… [Continue Reading]
A Kyoto-based company, Kyosemi, has created a spherical solar cell design. The “Sphelar” is a matrix of tiny, spherical-shaped solar cells, about 1mm in diameter. The spheres are designed to absorb sunlight at any angle, and therefore do not require motorization for tracking the sun. Because of their geometry, Sphelar cells even optimize the use… [Continue Reading]
