“I visited a friend’s house with a unique take on solar air heating. He coins his invention the Solar Coffin. This device heats air up to well over 100 degrees C within the “coffin” unit. The air is then moved under the slab of his house which stores the solar energy for release during the winter. This system is based on a system called annualized geo-solar developed in the US as a strategy to get off the heating grid.”
“We, Solar Action Alliance, are a group of environmentalists who want to spread the word about the most clean, reliable, and abundant source of renewable energy: the sun.
Today’s blog post is actually two stories in one. First, we’ll look at cutting edge solar cells, and then we’ll look at how improved, lower cost solar is ushering in a new age of electric transportation and home energy systems.
“Australian scientists from the University of NSW have set a new world record for the efficiency of commercially-viable solar cells.
“CSIRO has invented a new three in one solar air conditioning system that provides hot water, cooling and heating.
“It takes a lot of energy to heat water. Typically, up to 30% of a home’s energy consumption is used just to heat water for bathing, laundry, and cleaning. By installing a solar hot water system, homeowners can shave 200 to 500 kilowatt-hours off their electric bill per month, saving money and reducing pollution. Installing a solar hot water system is typically the first and most cost-effective step when turning to the sun for energy. Even if a photovoltaic system is your primary interest, a solar (thermal) hot water system along with a PV system will provide the best economics and space-efficiency on your roof.”
“See how Allan Savory, and his wife Jody, live in Zimbabwe, in traditional thatch-roofed mud huts, entirely off-grid with solar cells, LED lanterns, and solar hot water heater. He also goes everywhere barefoot. He was born and raised in Zimbabwe and currently lives approximately half of the year at his traditional home at the Africa Centre for Holistic Management.”
