The Solar Heating Patents of Dr. Harry Thomason

Below is a collection of solar heating and cooling  patents by Dr. Harry Thomason.  Dr. Thomason is known for the invention of the solar water heating trickle collector.  He built a number of solar homes and commercial buildings that used the trickle collector.


Below the patents are some additional materials on the Thomason collectors and homes.


All of this material was made available by solar engineer Nick Pine -- thank you Nick!

Solar Heat in Snow Country, Solar Today, Nick Pine
An article describing the the Thomason collector at the Richford Customs House in Vermont.

This collector has been providing 2/3rds of the heat for the Customs House since 1984.  Nick describes the installation, and how it has fared since 1984.
