Our house uses a number of different technologies to harness energy from the sun. Three are pictured above. The newest and most expensive of these was just hooked up to the grid today, providing 11.4 kWh for the internet dawlders of Australia. So long as I don't goof around on the computer all night, that should cover our home usage and then some. The Hills Hoist also efficiently utilized solar energy by drying three loads of washing. The seedlings in the pots on the black rack have yet to use sunlight to sequester atmospheric carbon dioxide in the form of tomatoes, but we are hopeful for the future.
