Introduction slides to solar thermal energy and solar hot water for a home or business. Solar hot water can save you or your business potentially thousands of dollars per year as well as have a great return on investment within 3 to 5 years. With rising electricity costs, solar hot water makes more economical sense.

PLEASE SHARE THIS VIDEO. Very few Australians are aware of molten salt storage technology and how it allows us to switch to 100% renewable energy in a very short space of time. Russell Beard of Earthrise goes on a tour of Gemasolar, near Seville, Spain - the first Concentrated Solar Thermal Power with molten salt storage (CSP+) plant to produce energy 24 hours per day. This power tower plant produces 20MW, enough to power 25000 homes but much bigger CSP+ plants are now being in the Middle East and the US that will produce 100MW and 150MW. Even larger CSP+ plants are possible. Research by Beyond Zero Emissions (www.beyondzeroemissions.org) and the Energy Research Institute, Melbourne University shows that a combination of * energy efficiency and an upgraded grid plus a mix of: * 60% CSP+ (comprising 12 solar regions each containing 19 220MW plants located in the high-insolation vicinities of Carnarvon, Kalgoorlie (WA), Port Augusta (SA), Mildura (VIC), Bourke, Dubbo, Moree, Silverton (NSW), Roma, Longreach, Charleville, Prairie (QLD)) and * 40% wind (comprising 23 wind regions in Albany, Bunbury, Esperance, Geraldton (WA), Cape Jaffa, Ceduna, Port Augusta, Port Lincoln, Streaky Bay, Yongala (SA), Cooma, Crookwell, Orange, Silverton, Walcha (NSW), Ballarat, Mt Gellibrand, Port Fairy, Wonthaggi (VIC), Atherton, Collinsville, Georgetown, Stanthorpe (QLD)) and * a small hydro/biomass backup for a few days in winter can provide all of Australia's energy needs including those of ...

This is part 2 of a tour with detailed explanation of a residential solar thermal/solar hot water heater system. Here I do into detail on various parts/components including the controller, temperature sensors, expansion tanks, flow meter, bypass valve assembly and stagnation control methods like vacation bypass valves, heat dump radiator, and covering the collector with a tarp. The system is the Enerworks one. It's installed in Ottawa, Ontario, Canada, so cold climate issues apply. The solar panels or collectors are flat plate type. The solar tank and the natural gas backup tank are shown, as well as the heat exchanger and all piping. How the solar energy from the sun heats the absorber in the collector and then the food grade propylene glycol (antifreeze) and water mix is also covered.
