If you have a lot of heat, then you can do what power plants do: use the heat to generate steam, and use the steam to spin a turbine. The turbine can drive a generator, which produces electricity. This setup is very common, but it requires a fair amount of equipment and space, but it can also be very compact.
The BioLite Camp Stove is a complete off-grid cooking and powering station powered by wood! Which means that while you’re using the stove to warm yourself, cook food, or simply for a fire, the thermo-electric generator converts the heat from the fire into usable electricity.
The BioLite CampStove generates usable electricity (2 watts) for charging almost all devices, LED lights, mobile phones, and other personal devices.
Burning only wood, the CampStove creates a smokeless campfire that can cook meals and boil water in minutes. Setup is easy, fuel is free, and flames are hyper efficient with performance on par with white gas stoves.
1. Heat – Core technology captures waste heat from the fire through a heat probe attached to the orange powerpack.
2. Electricity – Heat is converted into usable electricity via a thermoelectric generator. This powers a fan and sends surplus electricity to a USB charging port.
3. Air – The internal fan forces air back into the burn chamber dramatically improving combustion and creating a cleaner, more efficient burn.
