I call B.S. There is NO reason to believe this. Unrealistic confidence in the progress of battery technology is not new - it's been the state of things for well over a century now. (See Edison's Nickel-Iron battery, for one...) Sometimes real breakthroughs are required in science, engineering, or both. In the case of really useful batteries, which we do NOT have today, it's definitely both. These BREAKTHROUGHS (not incremental improvements!) are REQUIRED to do the things envisioned in the article. These breakthroughs may come tomorrow, OR we may be in the same situation with battery technology that we are with nuclear fusion: It's the energy of the future, and always will be - We've been "only 30 years away" from a fusion breakthrough and "power too cheap to meter" for at least 75 years now!
