Envirofit's Super Efficient Biomass Stove
Envirofit, a US nonprofit has created an innovative cooking stove for use in developing countries. Traditional cooking stoves burn all kinds of biomass including wood, crop waste and animal dung. The problem being that they spew out lots and lots of nasty smoke. Added to the fact that these things are used indoors and it turns into a huge problem. 1.5 million people a year (mainly women and children) die in indoor pollution related deaths.
Envirofit's new stove eliminates up to 80% of harmful emissions, and speeds up cooking time by as much as 40%. They also come in 3 different models, from basic to “family and festival” style.
