Some ice for your tube ride

While we're on the subject of international mass transit, if you frequent the London Underground, you might soon be benefiting from a cooling system that's more rudimentary than you'd think: melting blocks of ice. They'd be positioned in refrigerated holding tanks located beneath passenger seats; whenever the train goes underground, refrigeration gets shut off to prompt melting. When the train goes back up, the ice refreezes. Engineers hope to debut this "technology" as soon as next year, when they'll try it out on the Piccadilly line. Hopefully they'll transport the ice using the classic tongs! And as further flashback, maybe they'll even put "ice cards" in the windows. If the whole block ice thing doesn't work out, there are always liquid-filled cooling vests or, of course, some ImmobilICE Cold Therapy Pads from the good people at Cincinnati Sub-Zero.
