Gravity-Powered Shoe Air Conditioner (1994)

    • 1

Hot feet or cold feet? This gravity-powered shoe air conditioner can solve both problems: the device is installed on the heel of the shoe and uses “the natural gravitational pressure generated by the shoe during walking” to cool or heat the shoe.

And it doesn’t stop there: Israel Siegel, who patented the device in 1994, added that “various versions of the invention can be used for other temperature-changing systems,” such as household air-conditioning and refrigeration systems.

With this accessory, you’ll be the coolest person around.
