Flexible Solar Cells: SolarRolls by Bruton

Brunton Solaris 52: A Solar Charger

Brunton makes a range of flexible solar cells they call SolarRolls. These weather-proof solar cells can be rolled up quite tightly, and attached to a backpack. Seen here is a 14W model — it produces DC power even during low light conditions. SolarRolls come with a range of plugs, including a standard car lighter socket. […]

New 3D Solar Cells Created

Recently, we featured some intriguing spherical solar cells from Japan. But now there’s an announcement that unique 3D solar cells have been created using nanotubes. The 3D solar cells capture photons from sunlight using an array of miniature “tower” structures that resemble high-rise buildings in a city street grid. The tower structures, which are about […]

New Biofuel Cells: Electricity From Hydrogen and Thin Air

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 […]
