Yeah, that's impossible. (or a lie)
Where does the O2 come from...is it "free"?
Comments from Freepers on this thread were informative for me. The quick dismissals not so much.
We're going to see "climate neutral" goals here as soon as the Dems take over the administration. Any technology that undercuts their march is beneficial, even though it appears that some of these efforts are part of their scheme and therefore a scam. That's probably going too far. Flying, too, was once impossible and unbelievably stupid to try. But I'd say any invention that thwarts their entire effort would really be a game changer.
