Cut down on your power bills and help out the planet at the same time with Sunforce Solar Charging ($285) & Wind Generator ($480) Kits. The 60 Watt solar kit is designed for RVs, cabins, 12-volt battery charging, and other off-grid types of power demands with its 7 Amp charge controller, 175-watt inverter, and LED charging indicator, while the 400 Watt wind generator can power larger items like appliances and electronics, and features an aluminum and carbon fiber composite build, built-in regulator for shutting the system down when connected batteries are charges, and the ability to mount to any sturdy building, pole, or the specially-designed Sunforce 44455 Wind Generator 30-Foot Tower Kit.
Now there's an even better way to recycle your plastic two-liter bottles. Instead of taking them to the curb, just connect one to the Audubon Soda Bottle Bird Feeder ($15). Hang the sturdy cast zinc adaptor from a tree or pole, and you've created an economical, squirrel-proof bird feeder, satiating the neighborhood birds for months. It's gentler on the environment, and the birds will remember your kindness. Because you never know when that flock might turn on you.
