No more wasted heat: Pyroelectric nanogenerator

In Batteries, Science, technology on June 13, 2012 at 11:09 am

Pyroelectric nanogenerator: heat causes charges to separate in tiny zinc oxide wires. Electrons go in one direction, holes go in the other, and a current flows. From ACS Nano paper by Ya Yang et al.

Researchers at Georgia Tech published a paper in Nano Letters that describes how tiny wires made of zinc oxide generated electricity from heat. Unlike many other devices, this one does not require a gradient of heat — just heat.

Today’s technology generates a huge amount of waste heat. Devices like this could help us reclaim that wasted energy.

This hasn’t quite hit the news, so I don’t have a good link to an article yet. Here’s the original paper: Pyroelectric Nanogenerators for Harvesting Thermoelectric Energy
