So how do you get your e-goods from one place to another?
Unfortunately there is no common format (AA/AAA etc) for electronic rechargables, so leaving batteries at home and picking up new at the arrivals airport is not practical. A common format could make some sort of battery lease scheme viable where you can dump batteries at the departure terminal and pick up recharged batteries at arrivals.
Perhaps the planes can tow the batteries in a trailer glider. If that catches fire it can be jettisoned.
Likewise, having a clip-in cargo pod that could be jettisoned could work too.
