ladies and gentelmen this is our new type of solar home . it is better than other homes because it is environmentally friendly it is totally operated by solar energy . during winter outside air is captured by warm glass roof panels .then warm is forced down into a water tank by an air handling unit next .the water in the tank is heated and greater quantities of warm water are released . the hot air is then sent down a duet in under floor area after that . warm water rises through floor to the living speace . some of the heated air is absorebed by concrete slabs it is released at night .this process is reversed during summer
