I find it incredible how one many seems to be driving such a change in the future of our planet. Considering people have apparently been putting time and money in to this for decades, why are we not seeing more attempts like this? Is it because it's not considered lucrative enough for the capitalist market? Or is Elon just a very good at convincing us (me) he's breaking new ground?
