Background: A Sydney man has trapped the sun's rays to generate solar heat for a household hot water supply system. He's a backyard inventer, Mr. R. Brunt, (in the bow tie). His machine uses aluminium foil to reflect the sun's heat on to an absorber of black painted copper. Water runs through the absorber, and then through insulated pipes to its destination.
Brunt has estimated the heat inside the unit at 140 degrees Fahrenheit. For steam a motor creates a partial vacuum to condense the water - but that is part of another Brunt invention for converting salt or bore water to fresh drinking water, and for generating electric power. These inventions are for graziers and men in the out-back, the remote areas of Australia.
Mr. Brunt is proving his invention in the backyard of his Neutral Bay home, with Mrs. H.C. Bousfield, a neighbour, relying on the sun for her hot water.
Beneath glass the solar heating unit is eight feet long four feet wide and three and a half feet high - its bottom is V-shaped and lined with aluminium foil. Insulated pipes carry the water to a sixty gallon storage tank - hot water from the sun.
The final result is just like any other hot water system, but the heat of it has come 93 million miles from a temperature of 14 million degrees centigrade.
