The summer months are upon us.
I am already thinking of the fall and the passive solar heating box.
It was disappointing, that I could not get these into full production mode late 2012-2103.
I still believe in the solar passive window heating boxes, and know they will play an important role in the future.
I have been redesigning and using different materials to provide heating long after the sun goes down.
This summer, I plan on several prototypes.
Stay tuned please
