Abstract
A compact and economical supplemental home heating system utilizes a colloidal suspension of finely divided graphite particles as the collection medium. The emitter of the system is closely spaced from the collector so as to reduce complexity and cost of the system itself, as well as to facilitate inexpensive installation into existing dwellings.
