I am a research scientist at the Florida Solar Energy Center where I have been working since 1988. I research concepts for use in buildlng very low energy homes, as well as machines and technologies that make that magic possible. I live in a 'Zero Energy' home myself (, drive a solar-charged plug-in hybrid car and 'walk the talk'. It's not just trendy; it's the future!
