A container-sized generator that converts waste heat into energy

By Zoe Corbyn

What if hot air could become electricity? That is the goal of clean technology startup company, Alphabet Energy, based in California. It has a new so-called thermoelectric material which it says can turn waste heat – such as that from car exhausts and industry – into usable electric power more cheaply and efficiently than ever before, saving both money and the environment. “It is the first really low-cost efficient thermoelectric material for waste heat recovery,” says CEO and founder Matthew Scullin.
