Students at Rensselear Polytech are designing a solar-powered pasteurizer that can be used by village farmers in Peru. The sun heats water to boiling, and the hot water is used in a HTST (high temperature short time) pasteurization system. This will allow village farmers to obtain certification to sell their dairy products at market.
Solar power helping to improve the lives of the world’s poorest. It doesn’t get better than that.
