Vending machine dispenses free drinks during disasters

Fuji Electric Retail Systems is selling a new type of disaster-friendly vending machine in Japan that can dispense free beverages in an emergency (free Pocari Sweat, you say?). No, the machines aren't wirelessly connected up to some central control station that can switch them into disaster mode (though that wouldn't be a bad idea), rather the machines come with a built-in backup battery and can be preset to automatically give out free drinks to people when the power is out. Hard to imagine an American vending machine company doing the same thing, especially since it'd only be a matter of time until people figured out they could get a free Pepsi just by cutting power to the machine
