Horizon fuel cell
Fuel cells to charge small electronics continue to develop as a way to have a portable power source. Horizon Fuel Cell is now selling the MiniPak which can supply anything which needs up to two watts of power, such as a smart phone or digital music player. One of the cartridges, which hold hydrogen, is the equivalent of about ten AA batteries. The company is trying to bring down the cost of the cartridges, which it says can be recycled. It also includes a USB flashlight.
