Micro Fuel Cells Made of Glass — Power for Your iPad?

Engineers at Yale University have developed a new breed of micro fuel cell that could serve as a long-lasting, low-cost, and eco-friendly power source for portable electronic devices, such as tablet computers, smart phones, and remote sensors. The researchers describe the novel device in a paper published online in the journal Small.

An alternative to a battery, a fuel cell is an electrochemical device that combines hydrogen and oxygen to produce energy, giving off only water and heat as byproducts. But the materials and methods commonly used for making micro fuel cells are fragile, inefficient, and expensive. (more…)

Recycling Waste Heat into Energy: Researchers Take a Step Toward More Efficient Conversion

ANN ARBOR, Mich.— The right material wrapped around your car’s exhaust system could one day scavenge heat that would otherwise be wasted, turning it into energy to warm the cabin or recharge the battery.

Engineers and physicists at the University of Michigan have taken a step toward improving the efficiency of a promising candidate for this burgeoning power source. (more…)
