Teenager invented a new refrigeration process which doesn't use Freon. It uses Peltier chips. GM gave up on it years ago. We can remember the old and keep samples in museums and we must move ahead. New ways usually replace the old given enough time. See _http://www.sltrib.com/utah/ci_2841984#cool_ (http://www.sltrib.com/utah/ci_2841984#cool) Geoff, K6TFZ
