Is it possible to use earth or soil energy to power small homemade appliances? This research project gives an answer, although the battery endurance test is still in progress.
A soilurinebattery will not solve the world energy problems. But research into ‘Soil Power’ applications are very interesting because of the simple design and the easy to get, cheap components. I made two ultra-low power test devices as load . The basic battery consists of 4 soilurine cells. Enough to power kinetic devices for hopefully a long and moving life.
