Hugh Le Caine: Compositions & Demonstrations, 1946-1974
Hugh Le Caine, early electronic music pioneer, demonstrates his Electronic Sackbut in 1948 by playing the opening clarinet solo from Gershwin's 'Rhapsody in Blue'. Working at his Toronto laboratory, supported by the Canadian National Research Council, he went on to engineer and prototype the touch sensitive organ, variable speed recorder, multi-track recorder, and numerous other magnificent electronic instruments. And he demonstrated his inventions by composing his own music and by arranging well known tunes, demonstrating at the same time that he was a talented musician and that he had a great sense of humor. This CD, produced by Gayle Young, Le Caine's biographer, is a comprehensive compilation of his music, much of it not available before. The CD also includes many of Le Caine's spoken explanations of his demonstrations which make the CD come alive with human interest. In its commemoration of a remarkable personality and in the historical importance of its content, this is an essential CD. In the extent to which it is also enjoyable, it is a stunning accomplishment.

Yahoo Answers For Perpetual Motion Bird
Question Perpetual Motion Drinking Bird?
Is the famous toy (The Drinking bird) really a perpetual motion device or not? Please substantiate your answer. Some reliable websites confirming this would help. It's for a school project. Help me out Please!
Best Answer Obviously not. Sooner or later the bird will drink all the water and the water needs to be replaced. This represents something being added to the system to keep it running. Perpetual motion requires no input of any kind. What is happening is the same thing as adding gas to your car. If the car was a perpetual motion machine, it would never require gas. The bird is a sophisticated "love meter". This is a glass device with a reservoir on either end. Warming or cooling a particular end will cause the solvent inside to rush to the other end. The bird drinks when evaporation causes the solvent vapor in the head to condense. This draws liquid solvent back into the head. The head then dips down into the water because of the added weight. This wets the red fibers covering the bird's head. The cool solvent runs back down to the other end, causing the head to come back up. The head then cools enough to draw solvent back into it by condensing the vapor again. This will continue only as long as the head can evaporate water. Perpetual motion is impossible because one of the fundamental laws of physics states no transformation of energy is 100% efficient. Some is always lost as heat. One source of energy loss in the bird is the hip joint. It is not frictionless and this turns mechanical energy into heat. Heat is also absorbed by the water on the bird's head to evaporate it. It is then carried away into the atmosphere and never returns to the system. The ultimate source of this heat is the nuclear fusion at the center of the sun. Without the sun, the earth would be far too cold to allow water to exist as a liquid. It would probably be so cold the solvent inside the bird would also be frozen solid.

Question perpetual motion?
I've been told all my life that perpetual motion is impossible. Isn't the earth motion perpetual? Therefore, if we tap into such things as waves shouldn't that be counted as successful free energy. it mukes more sense than the"drinking bird" of the seventies
Best Answer Perpetual motion is the idea that a closed system (with no energy coming in) can continue to produce energy. When you rely on external forces such as wind, solar, etc... it is referred to as renewable energy. The earth spinning around the sun will go on for a very long time, but eventually the system will fail when the sun burns out or slighly before when the sun expands to cover the orbit of the earth... not scheduled any time soon so I wouldn't waste time worrying about it. That was a good question though since it points out the difference between these two energy types and addresses an underlying misunderstanding a lot of people have about perpetual motion.

Question Can the Drinking (Dippy) Bird be used on a large scale to generate power?
Is it possible to use the perpetual oscillating motion of the happy drinking bird (dippy bird) to generate electricity? The turbine will probably generate some amount of resistance, due to opposing magnetic forces, but I have a feeling that such resistance can be overcome. My reasoning is that the drinking bird currently actually overcomes mechanical friction in the axle, so why not the magnetic opposing forces of the turbine? Does anyone know of a feasibility study performed on this idea? I know this idea has been floating for quite some time on the internet, but has anyone actually built a working system, to atleast light a bulb? I know how the drinking bird works! As for some of the answers regarding the transport of water, the giant birds can simply be placed on the shores of a lake or any body of water for that matter.
Best Answer You know how the bird works, right? Evaporation of water on the felty beak cools an alcohol solution which then changes the balance point or the bird? Essentially, what is going on is movement of fluid that heats and expands and then cools and contracts. Sound familiar? The amount of heating and contraction is minimal in the finely balanced bird and the temperature difference doesn't have to be large. Now, the more energy you extract from the system, the greater the difference in temperature will have to be (to move more fluid to overcome more resistance to motion). Well, the idea is already in use, although the set up isn't the same as the bird, the principle is the same. Wherever you have naturally occuring heat close to naturally occuring cold, you can take advantage of the difference to generate energy. Solar heat engines rely on this by concentrating the heat energy from the sun to create the hot side. Geothermal engines rely on this by taking advantage of the cooler conditions underground. The real problem is getting enough bang for your buck. Running a pump this way to move water far from electrical supplies is a good use, but for most other uses, it's just cheaper and more reliable to use some sort of fuel.
