Recently, I was in Invermere again and I visited a friend’s house with a unique take on solar air heating. He has coined 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 grid. Take a look at the video below and let me know what you think!

UPDATE: May 4th 2014
Recently, my friend who owns this house decided that he wanted to get into farming so he has decided to sell his Eco Home. For more information on this home check out his MLS listing here. This home has the lowest utility bills in the East Kootenays and is one of the most beautiful hand crafted homes on the market. Definitely worth a look.

I would like to learn more about this Solar Coffin heating technology. Where can I learn about the system design principals, duct work sizing, solar chimney sizing and such? Thank,
Brad
Brad,
I would check out http://www.builtitsolar.com . There are a ton of great resources there.
