Even if we do not cause it, we should react upon it, and change the way we live and use energy.

Tesla? Suppressed knowledge? A secret space program?

Oh no. I am a professor. I'm not brainwashed.

the video was good but what is the point when there is unlimited free energy now? I guess the point is to make sure we keep using the forms of energy which make the energy cartels, oil companies,and governments cash flow continue. sorry, that is what has to end. pull your head out of your ass, open your eyes and know that free energy exists.

HI Have watched "Sustainable Energy - Without the Hot Air with David MacKay" and now have a clearer idea and most of my questions answered. This short film could be clearer, but I understand the nature of it, simplifying the concepts to make them instantly understandable... Getting there.
