A project in Okotoks in southern Alberta captures heat from the sun in summer and uses it to heat homes during winter. It appears to follow the geothermal heating concept employed at a home at 43 Bessborough Drive in Leaside. This project was profiled in 2011 and is re-published just below. Advocates of this method, like the man interviewed in this CBC report, speak of the practical to climate change. But it is also a concept to achieve uninterrupted power supply (UPS), or at least more consistent power when a home or neighborhood goes off grid. Home storage batteries fed by solar is another.
