New Cookstove Attachment Uses Loudspeaker Parts to Turn Waste Heat Into Power
by Rob Goodier, 03/30/11 as published in Inhabitat
This innovative new cookstove attachment solves two problems for off-grid homes: It turns the stove into a power generator and it improves kitchen air quality at the same. The attachment is a thermoacoustic generator based on a technology that NASA has tested for propelling space probes, but built with cheap parts, including an off-the-shelf loudspeaker.
The makeshift attachment uses waste heat from the stove to make a soundwave inside a resonator, which it then runs through a loudspeaker working in reverse to convert the sound into electricity. It’s a prototype now, but the goal is to make a model that generates 10W and costs about $25.
The stove is designed to work with most biomass-burning cookstoves, and part of the electricity that it generates powers an internal fan that blows smoke back over the flames to consume most of the pollutants.
Thanks for this its timely, wonderful lets join forces and save the worlds future is in our hands.
How best can we get this technology demonstrated to our communities in an energy poverty sate.
Do i need to pay for this, who do i pay .
Thanks once again.

Dear Richard,
The story contains a link to a larger story with some contact info. Unfortunately, it seems the technology is still being developed and is not yet ready for commercial deployment.
