> Under normal conditions, I use 350 kWh/mi (kilowatt-hours per mile). Say you get a good rate and pay $0.10 per kilowatt hour for electricity. That means if you charge your car at home, you're paying $35 per mile to drive. That doesn't seem right. Possibly it's watt-hours? That'd be a per mile price of 3.5 cents, which seems about the right order of magnitude.

Wikipedia says one version of the model S has a battery pack with 85 kWh of juice. So, yes, at 350 kWh/mi, you'd get further on foot... :)

That sounds about right - the 85 kWh battery of the Tesla would then get you about 240 miles range. Another interesting way of looking at this then, is that the amount of power required to power s single 100 Watt Light bulb for 3 1/2 hours could move an entire Tesla + person inside 1 mile. Wowsa.

  Or: an 85kWh battery could power a 13 watt CFL for 272 days. Or power every light in my house for 18 days.

  "could move an entire Tesla + person inside 1 mile"... on level ground. If you've ever had to push a car manually in that situation, you'll notice that it's very easy to keep it moving once you get started, as you only have to overcome the rolling resistance. I've never pushed a Tesla before but I'd bet that it's far easier than a regular car, and a regular car isn't that hard to push already. According to this page: http://physics.ucsd.edu/do-the-math/2011/11/mpg-of-a-human/ http://physics.ucsd.edu/do-the-math/2011/11/mpg-of-a-human/ A human walking takes between 100-200Wh/mi, so the Tesla isn't that far off.
