It was a little over a month ago when we told you about Core 77's Greener Gadgets competition…so if you had a design for a Green Gadget and you snoozed until now, well, you inevitably “losed.” The design competition submission deadline was January 27th and the results on the greenest gadgets of them all are in. The winner of the $2,500 grand prize went to Matt Meshulam and Zach Dwiel for their EnerJar, a DIY device that “measures the power draw of electrical appliances” and can be easily assembled by mostly anyone…even a monkey! Actually we're not sure about the monkey thing but we do know that the EnerJar can go a long way towards teaching people just how much electricity their appliances use, encouraging them to reduce their usage of the valuable resource. The EnerJar wasn't the only winner on display, but we don't have the space to talk about them all so we recommend checking out the winners at the Core 77 site, as there were many worthwhile projects in the running.
