The idea of the show might sound trivial to committed environmentalists, but is a good way to get people interested. The prizes look suitably green: Electrolux appliances, Air-Cell insulation, Solectair Heat Transfer System, Solahart hot water systems, SunPower photoelectric solar panels and a Toyota Prius hybrid car.
The Solectair Heat Transfer System is an interesting new Australian invention. Instead of a heater, ducts in a house are connected to fans which draw hot air from the roof cavity to warm the house in winter. This is similar in concept to the system in the new green office building in Canberra, but on a domestic scale.
