ORNL energy harvester turns heat waste into electricity, converts hot machines into cool customers
16th May 2011
The converter employs up to one thousand tiny cantilevers attached to a one square inch surface (e.g. a computer chip) to produce between one and ten milliwatts of electricity — admittedly a very small amount of energy. However, it’s creators are quick to point out that a slew of these converters could generate enough power to perform small tasks in the heat-generating device — things like sensing when a server room gets too hot for comfort.
This is pretty cool.
