Point Source Power’s cheap, rugged fuel cells can provide electricity where none exists.
In some parts of the developing world, people may live in homes without electricity or toilets or running water but yet they own cell phones. To charge those phones, they may have to walk for miles to reach a town charging station—and possibly even have to leave their phones overnight. Now a startup company spun off technology developed at Lawrence Berkeley National Laboratory (Berkeley Lab) has created a simple, inexpensive way to provide electricity to the 2.5 billion people in the world who don’t get it reliably.
Point Source Power’s innovative device is based on a solid oxide fuel cell that is powered by burning charcoal, wood or other types of biomass—even cow dung—the types of fuel that many in the developing world use for cooking. The fuel cell sits in the fire and is attached to circuitry in a handle that is charged as the fuel cell heats up to temperatures of 700 to 800 degrees Celsius. The handle, which contains an LED bulb, can then be detached and used for lighting or to charge a phone. (more…)
