Better Place has built a network of battery-switching stations in Israel that lets drivers traverse the entire country, swapping depleted batteries for fresh ones much like they would fill up at a gas station.
Our only complaint with Airport has been that, while the signal passed through plasterboard and brick--letting us stay online even while enjoying fresh air in a courtyard a floor below and 100 feet from the base station--we had an intermittent connection from the room opening out into that courtyard.
