Though we'd never recommend this method of charging, it does work.

In the video, you'll see a Tesla Model S charge up while being towed.  Maybe that is something you just have to do in Russia when you are in a pinch?  Anyway, the Model S owner gains back about 10 kilometers of range over 3 minutes worth of towing at 60 kilometers per hour - going by the dash readout.

This isn't the first time we've seen something like this.  A Nissan LEAF has been documented as charging while being towed too.

Why would anyone do this?  Just to prove it's possible, we guess.
