Tom Spears wrote an opinion piece for today's edition of the Ottawa Citizen on the subject. I'm inclined to accept all but Theme 4 re: the Space Station at this point, personally... (Oops! Can someone move this to the real-universe tech section, please?)
Whats so nice about this thread is the conflict with the autos.canada.com advert about going green with hybrids, such naivitey.
And I see the thread still hasn't been moved to Science and Technology yet; I'd have done it myself, but don't see the means of doing so at hand. Probably a case of "Plain Sight Syndrome" again...
