Chromasun Gets $3 Million for Solar Air Conditioners : Greentech Media

"Chromasun has raised $3 million to try to bring its solar air conditioning system to market.
The company, founded in 2008 by Ausra co-founder Peter Le Lievre, has created a rooftop system that collects heat from the sun with reflectors and transfers it into a fluid, similar to the process that large-scale solar thermal systems in the desert use. But instead of using the heat to make steam and turn a turbine, the heat is pumped into a double-effect chiller that, through a series of phase-change reactions and heat exchanges, results in cold air. So it's heat from the sun cooling rooms more efficiently than traditional air conditioners can. Go figure."
