Stirling Engine

THIS IS NOT MY MODEL - ALL THE CREDIT GOES TO SHELLY @ http://grabcad.com/library/stirling-engine I HAVE ONLY ADDED A RENDER AND STEP FILE. Just a thought how to make a stirling engine with a direct transmission drive to maybe a electrical generator,this could be used in a array with maybe a solar reflector. ps. this stirling motor would not work as it does not have a cross over link at the moment its just for demo purposes
