Swedish designer Peter Thuvander has designed a yo-yo powered charger for iPhones and other Apple handheld devices. “The remote control needs only 30 cranks–which is nothing when you yo-yo,” says Thuvander. He’s also thinking about what road warriors call “opportunistic charging”: “I think I’d at least use it as an emergency device for all the dead iPhone moments I have.”
Solar-powered Tree Charger – Great concept from designer Vivien Muller for a modular, Lego-like little bonsai tree with 54 mini photovoltaic panels as leaves to soak up energy from the sun and charge your gadgets.
Adapters get tucked away beneath a nice little tray, and your gadgets lay on top, basking in the shade.
