AFAIK dump charging buses is already being done. How else can you recharge the pack of an operational bus in a few minutes, every loop it makes? Note that there are two different systems that I know of for buses: - one where the bus is positioned under an arm at the stop and the arm with a large contact plugs into the bus for a conductive charge - I have seen the concept, I don't know if it is in actual use. - one where the bus is positioned over a loop in the bus stop and the bus gets charged wirelessly. This is not a concept, but in daily use on at least one commercial bus route in The Netherlands.

Then you would run around for awhile. While you were gone, the dump pack has recharged at some modest rate from the grid. Rinse and repeat. :-) Some folks have tried it with limited success in racing. Now the Norwegians have done it! This ferry is"dump charging" daily and has proved that what we have conjectured in the past works in reality. Buses and commuter trains are next. Maybe even cars. No need for a pack swap. Just fast charge. Can't wait to hear about the next implementation. Bill D.
