It is often said that we need a 1960s Apollo Program Moon Shot type effort to meet future transport energy needs.
Coincidentally, the new Tesla electric car may be built in the same city which built the Apollo moon capsules: Downey, California.
Here is a video from ABC News describing the new plant. The AP describes the 7-seater sedan car as the "Model S, which is designed to travel as far as 300 miles on a three- to five-hour charge." Tesla currently produces an ultra-luxury electric 2-seater sports car which costs almost US$110,000. The new sedan is expected to cost around US$57,000. This is still expensive but as with most automotive technologies it tends to start in luxury vehicles before entering the mainstream.
