it uses the same or less energy than a light-bulb!
that's just awesome. heck I can even forgive the fact that the speaker couldn't speak English very well! it's just that cool
(note: it's not that he couldn't speak English that bothers me, its the fact that he couldn't speak fluent English and yet chose to give a professional presentation with it. IMHO it would be better if he spoke in his native language and had someone who was fluent in English translate for him. but enough of that, THIS IS BAMF)
