I wrote a post about solar greenhouses earlier. A theme I will be coming back to many times in this blog. In my first post I only talked about passive solar greenhouses. Passive solar technology is very simple, no moving parts. Active solar uses fans to move hot air or pumps to move hot water, and more complex storage systems. Usually, they cheat a bit by using electricity, but they can greatly improve efficiency.
A company in Isreal has become, I believe the first, to manufacture active solar greenhouse equipment for commercial greenhouses. This will be a big leap forward in the commercial food industry becoming more green. To learn more about them see this post over at the Green Prophet.
