Boffins have created a small fan-based charger that can help boost the
battery life of consumer technology goods.
The
Hymini
USB charger is the brainchild of Arthur Huang, an architect and engineer
trained at
Cornell
and
Harvard
universities.
The device operates in winds above 9mph and up to 40mph, storing energy on
its Li-ion battery and outputting 5v to USB-powered devices.
A 20-minute breeze will power an iPod for 30 minutes, a PDA for 40 minutes
and a cellphone for four minutes, or allow a digital camera to snap 20 images.
The device also comes with add-on solar panels, four of which can be attached
to power the internal battery.
When there is no sun or wind, the Hymini USB charger can be plugged into the
wall and charged from the mains.
The device is expected to be out later this year, with a price to be
confirmed.
