We’re all trying to be a bit more green these days, I know I am. The Solar-Power Shower is a relatively affordable device that is the perfect accompaniment to any pool or beach house owner. Instead of delivering blistering cold showers after a dip in the water, its solar base can heat up to 8 liters of water to 140 degree F in just about 2 hours. With the plugged in hose, you can adjust the temperature to the perfect level and take comfort in knowing that you saved a few pennies. At $199, though, it will take you a many a summer to recoup your cost.
