Thermosolar By Creaspin

An autonomous solar cogeneration power station


Sun, Salt and Sound
Sun is captured, through self-orienting reflectors, and concentrated on the head of a tank which contains the salt.
Salt is our thermal battery. Like an ice cube that stores cold for your glass, our solution stores heat in the transition from solid to liquid salt.
Sound is used as the thermodynamic cycle. It transforms this heat (hot source) into electricity on demand. The secondary (cold sink) of the thermoacoustic engine is used as a source of co-generation heat, resulting in an advantageous overall efficiency.
Due to technological simplicity, although patent pending, we can reach 50 years of electricity supply without waste.
