    Hot Ice

    If you inserted a rod with a couple of RGB LEDs on the end ito the solution, It would be neat to see if that crystal dandelion would glow different colors...

    Four Cylinder Air Engine, Experimental

    http://www.ebay.com/itm/V-Twin-V-Type-Mini-Hot-Liv...Greg,Lovely air engine!Have you seen these... you can run a plastic engine with steam. I have one and it cranks like the devil with the tuna-can boiler. My guess is the cylinder and piston are UHMW or some other lubricious engineering plastic that can take a little heat. Bill

    Flying Pumpkin (Balloon)

    Yeah, I have to totally agree with that... my first thought was "YOU CAN ACTUALLY CONTROL THE BALLOON'S FLIGHT. WOW." Probably a great personal fan too. "My left ear needs cooling now also."Another in a long line of awesome projects from gzumwalt. Thanks you!

    Wooden Finger Engine

    Hi Dr. Senft,Great Instructable and video. I saw your article in Nuts & Volts on the CSS555 and then went to your Instructables list. (To those who are reading this, Dr. Senft invented, among other things, the type of "coffee cup" low delta-T Stirling engine you see all over, including in Instructables.) You really should publish a collection of your articles from Live Steam in a book including the steam powered Tonka truck, the Moriya Fan, the thimble engine and that wonderful little O-gauge train. I think a whole new generation of builders would enjoy that immensely. Thanks for continuing to put forth such awesome projects. -Bill

    A Beginner's Guide To Stirling Engines

    Awesome Instructable, even if I did have to look up IB and MYP. ;-)This is a Senft Stirling engine, first conceived and developed by Dr. J. R. Senft of University of Wisconsin River Falls, during a friendly competition with Dr. Ivo Kolin of University of Zagreb in the 1980's to build an engine that would run on the lowest temperature differential. Dr. Senft, an awesome machinist as well as a mathematician, was an inspiration to me as a teenager reading Live Steam magazine, and one of the reasons I became an engineer. A neat illustration of the engine and the story behind it is here: http://www.animatedengines.com/ltdstirling.htmlThanks and keep on making Instructables!
