Husk Power Systems is a for-profit (which I read as economically sustainable) company using rice husks, a form of agricultural waste, to power rural India.
You can see their company website Here
, and their PopTech presentation Here
There are several reasons I really like this project:
1. It's economically sustainable. They make a profit by powering rural India. This means they have possibility for lots of growth.
2: They hire locally, in India, creating jobs and adding to the economy
3: It is a sustainable power source, using something grown all the time and that would otherwise go to waste.
This seems like it has a big advantage over things like solar power for the developing world, since it can be totally made locally and it doesn't seem to require fancy technologies. I wonder though how it works. Do they burn the rice husks? That would be harmful for the environment if so. I can't find anywhere where they say how it works, though. Can any of you find anything?
