GM today announced the roll out of their new "UltraCharger" network promising full recharge times of less than 1 minute for a Chevy Volt, 2 minutes for a Spark EV. The first station was recently completed and tested at the Chicago Willis Tower.

"We are awed by the technology and possibilities," remarked one who attended the private test. Although no press was allowed, one enterprising photographer managed to capture the memorable moment:

Elon Musk, always ready with a tweet, was stunned and silent when shown the UltraCharger photo. Details of how the energy transfer actually takes place have yet to be revealed, though it appears to use a new type of induction charging.

Drivers are advised to not wash the car while the UltraCharger is operating.

Oh, if only. :). Saw the lightning shot in the article above, and thought, how many batteries could that charge?

Drivers are advised to wear thick rubber soles and keep their feet (knees?) together while the UltraCharger is operating.

Practicing your golf swing with a metal shafted club anywhere in the vicinity of the UltraCharger is definitely not advised.

Well, according to Wikipedia, the average lightning strike is 500 MJ. Since there are, by definition, 3600 J in a Watt-hour, that means the average strike has 139 kWh of energy - enough to fully recharge 10-12 Volts. Lots of power there - you just need a system to capture and control it all. :)

I thought lightning had 1.21 gigawatts of power. :confused:

Well, GM can do the same in New York, where the Empire State Building has been struck by lightning over 1,000 times a year for the past 83 years. If ConEd could capture all that energy, they could give the city free energy for weeks! Now the new One World Trade Center (1,776 feet tall) will get its share of strikes, and possibly charge Volts, Sparks, and Tesla models!

Yes, but only for 0.413 seconds. Hence, 500 MJ. :) Looks like that movie was pretty accurate, lightningwise, even if he pronounced it "jiggawatts."

Correction: lightning strike discharges take microseconds, not half a second. The movie was inaccurate, after all.
