Green concept harvests free green power from wind and sun

There is no shortage of green gadgets on the market today. Typically you can chose from solar or wind power generators. I have never seen a device that uses both solar and wind power to generate electricity for your gadgets and other needs.

A concept designed by Cheng Peng is one green gadget that should really be made into a real product. The collapsed the device looks like a small stick and you can plug it into the AC outlet to power GPS devices and other gadgets when power is available.

When you are out in the wilds, the sides of the tube open up in four petals that turn into a windmill for harvesting wind energy. Those same wind petals are covered in solar panels to grab energy from the sun. It would be very cool and more efficient if you could generate power from wind and sunlight at the same time with one device.
