Powerful, Lightweight

Microengines for UAVs





2h+ flight times and payloads

unrivaled by batteries and fuel cells







The Reebeez microengine has a specific energy 8x better than

lithium polymer batteries at a third of the cost.



  • Due to weight limitations of engines, small UAVs rely on lithium polymer batteries
  • As a result, small drones can rarely fly for more than 18 minutes
  • Reebeez microengine is a hybrid design of thermoelectrics (TEG) and thermophotovoltaics (TPV)
  • Uses state-of-the-art SiGe and skutterudite thermoelectric generators
  • Runs on butane to achieve a specific energy > 1.5 kWh/kg
  • With the Reebeez engine, a 400g drone can fly for over 2 hours
