In Malawi, villagers, NGOs and Carbon Trading businesses have revolutionized how people manage their dwindling forest resources by using a new technology in an ancient way. The Mbaula Chititezo Stove (which means saving the environment) reduces household wood consumption by up to seventy percent, allowing forests to regenerate and helping households limit their exposure to dangerous smoke. Supported by the German GIZ and Hestien Innovations. Contact Them: hestian.com

Maybe we (Biochar community in Australia) can collaborate with the Malawi Stove team, for further improvements.
Sounds like a great idea!
