About the Truly Passive Greenhouse


The problem: All greenhouses in a cold climate need heat.  So they consume energy and require human discipline.  At the same time, it is possible that on a sunny day, a greenhouse can get hot enough to kill everything inside.  

The solution: We have a plan to create a greenhouse that requires no heat, and will never overheat.  Mostly, we will use the heat from the summer to heat the structure through the winter.  And if we have a moment of excess heat we will passively store it and save it for later - with no harm to the plants, all with no need for human discipline.

The Greenhouse is Built, and the Movie is complete!
