The E-Bag from Hungarian designer Apor Püspöki cools your drink while you walk. How does it work? Quite simply: The rotating handle is attached to a dynamo that uses arm motions to charge a battery.
“The cooling system makes use of the Peltier technology, a kind of solid-state heat pump that transfers heat from one side of the device to the other side. The cooling status is indicated by three LED lights.” Did someone say eco joy? I think so. This device makes incredible use of all the energy that we expend physically. Instead of letting it go to waste, it transforms our power into something beneficial so that we can make use of every available resource in our bodies and cut down on external energy sources. Walking has never been cooler. Pun intended.
