Re: David Brin's latest novel, and a TED talk
You could become a rich man if you came up with a cheap/efficient way to crack water into hydrogen and oxygen.
Exactly, the currently catalytic cracking method is extremely ineffecient and very costly to produce a pittance of fuel. Yet similar "news" outlets to the ones RAMA is posting from where banging on about cheap, clean fuel cells within a few years.
Solar is already demonstrably getting cheaper. It's also no mystery...it CAN provide the power needed if harnessed.
You cannot go against nature
Because when you do
Go against nature
It's part of nature too
