Stirling engine DIY Intex pool heater

Stirling engine DIY Intex pool heater, sears Automatic coal stove. TECH:The biggest can made stirling engine is running and heating water to warm my intex pool. The engine hot end of the displacer cylinder is set into the fuel feed port in the top of an antique sears automatic coal fired chick brooder stove. Burning scrap wood to power the stirling engine with waste heat materials from around my home. This stirling engine project, hand made and build from scrap, and re-purposed parts. Originally intended to be run inside my house to charge batteries, as part of a chp system, the engine is being tested as a prototype and is "just for sizing" as this stove is not meant for indoor use. This combination of coal stove and stirling engine is raising the temperature of my pool water from 72 to almost 100f with gravity syphon water cooling. The engine also ha a small electric pump for water cooling, but is not being used during this test.
