The Sun Lizard is a new home ventilation system that uses solar power to cool your home in the summer and heat it up in the winter. It works by moving air around the house and warming or expelling it as needed. Quite clever really, although it may work better in a place like Oz than in grey London. The short video gives a good graphical explanation. [Thanks Dan]
Introducing the Sun Lizard, a unique way of heating and cooling your home. Each day, we often leave our home closed off from the surrounding environment, trapping the air inside. We then return to a home that reflects the season: hot in summer, cold in winter. But by allowing the building to breathe by reheating warm air in winter and letting hot air escape in summer and drawing in cool air from outside, our homes can remain more comfortable year round. The Sun Lizard uses principles of natural air movements, solar energy and heating cooling dynamics to will allow you to heat and cool your room to something much closer to your comfort level.
