Simple solution that save lives
The main problem when people stay in high altitude is less oxygen and cold weather. That's what happen in Baneara when you stay 1800ft above sea level.
People in Baneara, Samosir used to make a heater out of traditional wood stove. Because at night the temperature will drop to 10 degree C.
North Sumatera is second highest on fire wood usage as a medium to cook just below NTT. This is the main problem, because they don't understand how dangerous the smoke out of fire wood.
In order to save one of the village in North Sumatera, which is Baneara. I build RocketStove, where they can still use fire wood as a burning material but 70% lesser smoke and 30% wood efficiency.
