Sun Lizard Solar-Powered Home Heating and Cooling

The "Sun Lizard" is a self-contained, solar-powered heating and cooling system that brings in cool air in the summer and reheats already warm air in the winter to help manage temperatures without completely shutting off your home from the outside air. Its summer functions don't seem that profound—it's essentially a solar-powered attic fan—but the ability to capture the warm air from your attic and recirculate is clever.

The Sun Lizard is currently available in Australia and starts at $3,500 AU, plus mounting accessories.
