Finally, Better Batteries - Technology Review
Way better batteries, commercial space exploration, am I the only one getting the idea that Heinlein is finally right? OK, the old geezer project the "shipstone" battery for the 1950s and Harriman's space exploration for the 60s and 70s but still....
Even the space elevator, which many SF writers deem a necessity for decent space exploration is now getting some of the attention it deserves. Granted, it will take quite some materials research but at least some people are taking the idea serious. (remember the space elevator from Kim Stanley Robinson's "Red Mars" which was shot down? Excellent reading though, the whole trilogy)
