There’s no doubting the effectiveness or the cool factor of harnessing the sun, and if you’d like to extend it to the smaller devices in your house, the SunMod will charge any AA or AAA battery powered device, no outlet required.
It won’t save you a ton on energy bills, and it’s probably not that useful for your TV’s remote, but it’ll do a great job of powering your iPod speaker system outdoors, when outlets are scarce (and when cords risk your picnic guests faceplanting on the concrete). All you need is the $US20 kit and a few rechargeable nickel-metal hydride batteries, which you can easily attain from the usual suspects (Duracell, Energizer and others). It’s a pretty simple, fun DIY project that will not only help you squeeze extra hours out of your battery-powered devices, but start some conversations as well. Hit the link to check it out.
