#4 Solar Bluetooth
Ride, drive (not very eco), walk and talk hands- and grid-free using this solar-powered bluetooth device from Iqua. Dubbed SUN, the device is best suited to the urban eco-adventurer—the bike commuter, walker, jogger or park lay-about. A lithium polymer battery provides up to nine hours of talk time on a full charge, 200 hours of standby time and can recharge within two hours.

These are all great products! The Solar Light Cap would have been a great contender for the list as well! It provides 3-4 hours of light from a full day’s charge of its built in solar panel and has 4 modes including Alert, SOS, Strobe and Dimmer. It is weatherproof and provides over 5000 hours of free light from the sun through 2 ultra bright LED lights. Check it out at http://www.currentwear.com.
