Hello, I'm The Original Bob. An edit that you recently made to Applications of the Stirling engine seemed to be a test and has been removed. If you want more practice editing, please use the sandbox. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks! The Original Bob (talk) 14:38, 4 July 2014 (UTC)
