While I think charging cell phones and Telsas is a problem, getting cheaper than petrochemical energy is the key. So I have always thought that some sort of space-based energy source was the solution but how do you get it back to earth? 1000's of small solar cell beaming back energy concentrated at one point would be a great solution. How much would this cost would be interesting to find out?
