Generate Electricity using Heat

Thermal Electricity Generator, Generate Electric Current using a Candle. Here is a simple mini project to generate electricity without any mechanical parts i.e. Dynamo, Gear, Turbine etc. Heat is directly converted in to DC current with more efficient and few parts. Picture of our Thermal power generator Output power will depend on how much temperature difference […]
