Solar Power can be expensive for something as large as a house, but think about this energy saving concept. The Inlet-Outlet can turn an appliance or other device into an energy generating one. For example, take something like your dryer that already uses way too much energy with a panel behind it capturing the excess heat and turning it into electricity. An entire system could turn all those plugged in exercise vehicles at your local gum into a mini-power plant. Kudos to Carla Diana and Jeff Hoefs for the smart design.
