Each year the Consumer Electronics Show lights up Las Vegas with an exhilarating showcase of cutting-edge technology.
Although the Nevada desert may not be the first place you'd look for energy-efficient tech, this year we spotted an array of green gems that exhibit trends towards more efficient, versatile, and sustainable gadgets.
From universal eco chargers to multi-tasking sunglass cameras and kinetic-energy harvesting gizmos, read on for our top 5 green gadgets from CES 2011!
Lady Gaga's Polaroid Camera Sunglasses
Lady Gaga teamed up with Polaroid to create this pair of high-tech stunner shades that conceal a secret surprise - a 12 megapixel camera that captures the world as you see it. The multi-tasking GL20 Camera Glasses also boast twin 1.5 inch OLED screens that can play back photos and videos for whoever you're looking at.
nPower PEG Kinetic Energy Charger
Add a spring to your step and some watts to you walk with the nPower PEG - the world's first handheld gadget charger that captures and stores your kinetic energy. Simply toss this pint-sized power charger into your backpack or briefcase and it will capture kinetic energy from your daily activities and transform it into electricity to juice your gadgets on the go.
eCoupled Wireless Tesla Charger
Wireless charging is a hot topic for tech enthusiasts, so we were thrilled to see eCoupled roll out a new system capable of charging a Tesla at this year's CES! Simply park your EV over the PowerSpot's halo of blue light and it will transmit electricity via an induction pad at distances up to 4". The technology isn't quite ready to hit shelves and no charging times were available, but it's certainly something to keep an eye out for.
IDAPT Universal Gadget Charger
With today's prevalence of handheld gadgets it seems everyone has a shoebox filled with bulky wall wart chargers collecting dust. The IDAPT i1 Eco is a universal charger that can power nearly any gadget, and it's made from recycled materials to boot.
Ford Focus Electric
Perhaps the biggest news from this year's CES came from Ford as they unveiled their first all-electric car. The Ford Focus EV is an electrified version of their popular small car that will get a better mile-per-gallon equivalent than the Chevy Volt and will recharge in half the time it takes to juice up a Nissan Leaf.
