http://www.wired.com/design/2013/10/an-ingenious-wristband-that-keeps-your-body-at-the-perfect-temperature-no-ac-required/ [quote]Wristify, as they call their device, is a thermoelectric bracelet that regulates the temperature of the person wearing it by subjecting their skin to alternating pulses of hot or cold, depending on what’s needed. The prototype recently won first place at MIT’s Making and Designing Materials Engineering Competition, netting the group a $10,000 prize, which they’ll use to continue its development. It’s a promising start to a clever approach that could help alleviate a serious energy crisis. But as Sam Shames, the MIT senior who helped invent the technology, explains, the team was motivated by a more prosaic problem: keeping everyone happy in a room where no one can agree where to set the thermostat.[/quote] It looks kind of stupid, but you would be wearing it around the house anyways...most of the time. It is definitely a neat invention though, and if the price is right, I would definitely buy one. Hopefully they make it look a bit less like a...well...computer heatsink.
