Update: Pop Can Solar Furnace

It's a bright sunny day in Halifax, so the pop can solar furnace is working at full tilt.

The temperature in the solarium is over 25C and the spill over has boosted the dining room to 21.8C. Since warm air rises, the upstairs of the house is 20.6C. This would be further enhanced by a fan, but it's pretty good for just passive. Free heat!

For comparison, the current outdoor temperature is 4C.
