Even 20kW will only get you 40-50 miles per hour of charging a Tesla. The Volt weighs an entire thousand pounds less than the Tesla, and it gets a much better watts-to-mile ratio. Even then, the Volt's generator is all the way up in the 55kW range. That's a far cry from gas or diesel, where a five gallon can can be transported by a friend in any vehicle, poured into any car in a matter of minutes, and will get you 100-200 miles. Towing to the nearest fixed rapid charging station seems more practical than the generator vehicle in many cases, provided tow companies will tow the vehicle. One interesting idea might be for Tesla to provide a "towing mode" that raises the ground clearance as the batteries are dying in order to make it easier to load the car onto a flatbed - that, along with education of tow companies, could be very beneficial to improving the outcome of these "stranding" situations.
