Tom Edison felt that "Genius is 1 percent inspiration and 99 percent perspiration".
There's plenty of inspiration in this world to go around, but the boys at Tesla are right now finding out how tough it is to be a true genius due to that 99 percent part. I hope they don't take a bunch of greedy investors down with them.
I'll place my EV bet with the adults in the car industry and the scientists/engineers working with them trying to come up with a battery technology that has the energy density of gasoline and diesel. (And to go along with the energy density storage challenge ... how about coming up with affordable panels for solar farms with efficiencies way higher than the current 20 percent range?)
