Meaghan's Minute: Battery Harnesses Heat Waste

Today on Meaghan's Minute, brought to you by Memory Protection Devices, researchers at Stanford University and the Massachusetts Institute of Technology have found a new alternative for low-temperature waste-heat conversion into electricity -- that is, in cases where temperature differences are less than 100 degrees Celsius.

The new system is based on the principle known as the thermogalvanic effect, which states that the voltage of a rechargeable battery is dependent on temperature, and aims at harvesting heat at temperatures below 100 degrees Celsius, which accounts for a major part of potentially harvestable waste heat.
