Rifken at ECB The model he lays out mirrors the thinking in Musk's principles but explains from a physics standpoint vice unreasonable economic standpoint why petrol sucks (really sucks) and will never get better. Also it seems we are about to have tech that goes beyond green. If you watch this second NYT interview somewhere around the middle of the short video Nassim starts talking about the energy implications. One thing I like about his approach besides him possibly being up for the Nobel prize against all odds (pretty astounding finding with deriving mass and recognizing the implications) is that he talks about having to go outside of the orthodoxy in science education because evidently as we see with medicine its predictably money and power compromised. Kind of speaks to the issue of us still having a 18th century power system. In terms of gravity tech that's been in the background now for at least a decade. You can see in in recent science fiction like Daniel Suarez' "Influx."
