Especially when it’s hot, we need some cooling. Therefore we are developing a refrigerator that uses the power of the sun to convert heat to coldness without the use of electricity.


How it works: The solar refrigerator works similarly to a conventional refrigerator and transports heat via a circuit from the inside out. Normally, this cycle is driven by an electric pump, but we use heat to power this cycle.
We derive the heat from – you guessed it – the PhotonGrill.
