That makes my brain hurt.
The second part is that because it's going twice as fast, the air pressure from the speed collapses the belts and causes the tire to self-destruct.

This is why engineers need to run the world.
Vote ElSupreme 2020!
I've worked on plenty of products that make me question the rationality of engineers :wink:
Thanks for finding and posting this article. Seems as if the 500+ mile battery is still a few years away. Elon said they can produce a 500-mile battery pack now. However, the weight, cost and recharge time are not feasible. I think this technology will jump by leaps and bounds when Model S and X are on the roads by the thousands. It would be a big incentive to further research.
This caught my eye:More silicon nanotube goodies from Yi Cui.
20C !?! That would allow the battery to charge completely in 5 minutes. Of course, getting 85kWh of power into a battery in 5 minutes requires a rate of charging of about 1,900 kW (including losses). Pzzzap!Batteries containing these double-walled silicon nanotube anodes exhibit charge capacities approximately eight times larger than conventional carbon anodes and charging rates of up to 20C (a rate of 1C corresponds to complete charge or discharge in one hour).

•Minimal Capacity Loss, Even After 6,000 Charge-Discharge Cycles
•SCiB Batteries Charge in as Little as 10 Minutes
Substations will be the gas stations of the future if you want that kind of power transfer.

The problem with that idea might be that power plants need to be run near capacity as much as possible to be profitable and to realize good efficiency. Having a turbine oversized and underutilized most of the time is going to be expensive and inefficient, as is having a large enough pipeline that can feed it's maximum demand. It might not be a practical setup.
