I’m writing to share this recently broadcasted TEDx talk on how we can save two million lives a year by changing people’s cooking appliances. The BioLite HomeStove is a new technology that generates electricity from the heat of the flame. This enables the stove to power an internal fan, which cuts smoke by 95% and generates surplus electricity to charge mobile phones and home lighting. Drawing on cultural anthropology and user-centered design, the team has developed and will distribute the stove in a manner that is consistent with local cultural, religious, and culinary practices.
