Recorded February 2013If there's one thing that can't be said of Elon Musk, it's that he doesn't try his best. Few entrepreneurs succeed in just one of the many difficult fields that he's tackled, but it's almost unprecedented to see a single person attack on so many fronts at the same time, and with the goal of making the world better, not just making money (he could have made more in easier industries, I'm sure). Armchair coaches might say that his approach is not the best one, or that his priorities should be revised, but few of them actually try, and that's part of the reason why the world has so many problems. We need more people to try to make their visions of a better world come true!
Indirect fusionOne interesting prediction by Musk: Solar power will beat everything else, including natural gas, and he believes that it will represent a plurality (ie. more than any other source) of power generation within about 18 years. This would mean that the exponential curve of solar power generation will get quite steep in the later part of that period, but that's not unheard of in history.
If you want more, there's another recent presentation that Musk gave at the University of Oxford: Tesla CEO Elon Musk Speaks on the Future of Energy and Transportation.
