The great exaggerator is at it again:
Elon Musk knows how to make promises. Even by his own standards, the promises made last week while introducing two new Tesla vehicles - the heavy-duty Semi Truck and the speedy Roadster - are monuments of envelope pushing. To deliver, according to close observers of battery technology, Tesla would have to far exceed what is currently thought possible.
Take the Tesla Semi: Musk vowed it would haul an unprecedented 80,000 pounds for 500 miles on a single charge, then recharge 400 miles of range in 30 minutes. That would require, based on Bloomberg estimates, a charging system that's 10 times more powerful than one of the fastest battery-charging networks on the road today - Tesla’s own Superchargers.
The diminutive Tesla Roadster is promised to be the quickest production car ever built. But that achievement would mean squeezing into its tiny frame a battery twice as powerful as the largest battery currently available in an electric car.
These claims are so far beyond current industry standards for electric vehicles that they would require either advances in battery technology or a new understanding of how batteries are put to use, said Sam Jaffe, battery analyst for Cairn Energy Research in Boulder, Colorado.

I'm not buying one of these things no matter what he says. If I have to, I'll walk more.
