You could power the entire United States with about 150 to 200 square kilometers of solar panels, the entire United States. Take a corner of Utah... there's not much going on there, I've been there. There's not even radio stations.
So, there's quite a big keep-out zone, and when you factor the keep-out zone into account, the solar panels put on that area would typically generate more power than that nuclear power plant.
We have this handy fusion reactor in the sky called the sun, you don't have to do anything, it just works. It shows up every day.
The primary means of energy generation is going to solar. It will at least be a plurality, and probably be a slight majority in the long term.
I don't think very highly of Henrik Fisker. [...H]e thinks the reason we don't have electric cars is for lack of styling
A battery by definition is a collection of cells. So the cell is a little can of chemicals. And the challenge is taking a very high-energy cell, and a large number of them, and combining them safely into a large battery.
The fuel cell is just a fundamentally inferior way of delivering electrical energy to an electric motor than batteries.
It would take six months to get to Mars if you go there slowly, with optimal energy cost. Then it would take eighteen months for the planets to realign. Then it would take six months to get back, though I can see getting the travel time down to three months pretty quickly if America has the will.
It's obviously tricky to convert cellulose to a useful biofuel. I think actually the most efficient way to use cellulose is to burn it in a co-generation power plant. That will yield the most energy and that is something you can do today.
Obviously Tesla is about helping solve the consumption of energy in a sustainable manner but you need the production of energy in a sustainable manner.
