To echo Aimless' answer, it's to drive an integrated fan that increases stove efficiency--both the amount of heat generated and a more complete combustion. So, a hotter, cleaner stove than a passive design offers for folks off the grid. Think turbo!

I'm no EE so don't know whether the design could be advanced to the point where you can shunt off excess electricity to charge a storage battery. Conceptually, I could envision it but it would be a side benefit, not the system's main intent.

Cheers,

Rick
