It’s that time of year again — and we don’t mean time for ol’ fatty to come sliding down your chimney. This is a time for a fresh dose of innovative, eco-friendly ideas; time for Core77′s annual Greener Gadgets Design Contest. The competition asks everyone from design students to established firms to create products that speak to pressing environmental issues by working to decrease our carbon footprint, use energy more efficiently, or improve upon social or educational development. If you think you’ve got a concept that you’re confident will impress, just read the How To Enter details and get it in before January 15, 2009. All of the best entries will be posted online for public voting and the finalists will be judged live at this years Greener Gadgets Conference on February 27th in New York. The first place winner takes home a $3000 prize and the two runners up take home a nice $1000 bounty. Last year’s winner was EnerJar, a DIY device that “measures the power draw of electrical appliances.” So that’s taken.
