 | Heat engine in Phun The red object is a heat source (bounce larger than 1). The blue object is a coolant (bounce = 0). You can get the scene file at http://www.geocities.jp/int_real_float/svg2phun/Media.html and PhunBox. I used SVG2Phun and involute gear tool. |
 | Ergenics Hot Water Heat Engine Demonstration Video shows two buckets of water -- one hot, the other cold. As the two heat exchangers from the Ergenics apparatus are immersed into the two buckets, the temperature differential drives a turbine, powering a generator that powers the light. Ergenics is developing a metal hydride heat engine that converts the energy from hot liquid (e.g. solar hot water) into electricity for an estimated cost of about 1¢ per kilowatt hour. For example, solar panels produce hot water which is pumped to a hydrogen compressor that compresses a gas that is then expanded in a hydraulic motor-generator set that produces electricity. The technology has a multitude of other applications and iterations. Please see www.ergenics.com |
 | Mk II heat engine made from cans My second attempt at a heat engine, building on the lessons learnt from the Mk I (also on youtube). Improvements this time: The cold end (top) of the cylinder has a small open tray for ice/water. The crank arrangement is more rigid. The large cylinder uses a seamless can as the Mk I was leaking at the base after receiving too much flame. The geometry of the displacer linkage has been changed with the stroke halved to 22mm and a longer connecting rod this has reduced the angle the con rod has to adopt as this was causing friction in the crosshead. In this version the crosshead is also longer with an additional upper bearing, although this proved unnecessary. Observations on this effort: Friction remains a problem although tolerances are much improved and I was determined to keep this very basic; further improvement would require ball races and better materials for power piston/cylinder. The knocking noise is due to a sloppy connection at the top of the power piston so this is loosing energy. Although the cooling tray keeps the top of the cylinder cool the sides right up to the top still get very hot so this needs improvement. |
 | How to make the rubberband heat engine (1) an axle I'll show you how to make the rubberband heat engine. First we must make an axle of the wheel. I glued four prastic beads with a piano wire. I also showed some examples of rubber bands in the biggining of this video. |
 | Paper heat engine Puskas engine works from water evaporation and it is the most simple LTD heat engine to make. It is only from paper and similar to drinking bird.It is not as complicated as stirling engine or drinking bird. www.heatengine.uw.hu |
 | Duplicolor High Heat Engine Paint Both Engine Enamel and High Heat Paint formulas now contain ceramic resins for maximum heat dissipation and gloss retention. The resins also offer protection from exposure to excessive heat and automotive fluids. Developed and tested in the lab, Dupli-Color® Engine and High Heat Paints will perform to the most rigorous standards of racing and street rod enthusiasts. Here's where to buy it: http://duplicolor.com/solutions/wheretobuy.html |
 | Rubber Band Heat Engine I've been made the Rubber Band Heat Engine, which is described by Richard Feynman in his book. As the rubber bands are heated by the lump, they contract, moving the center of mass away from the center of rotation. This causes the engine to rotate! |
