Lust for power: Engineers develop non-toxic material that generates electricity through hot and cold

Thanks to the discovery of a new material, a cooking pan could generate enough electricity to charge a cellphone in just a few hours. The team found that a combination of the chemical elements calcium, cobalt and terbium can create an efficient, inexpensive and bio-friendly material that can generate electricity through a thermoelectric process involving heat and cold air.
