Artificial Muscle (AM) have been studied and developed by several institutes and colleges. They'll gonna use it for robot's actuator. But i got idea to use it to tap energy from magnet. Check out some links below: http://www.ai.mit.edu/projects/muscle/papers/ http://ndeaa.jpl.nasa.gov/nasa-nde/lommas/ http://www.mpg.de/news99/news26_99.htm AM take a benefit from rapid volume changes of material caused by changes of it's environment, such as temperature, pH, electric current, electro-static field, and also magnetic field! They're now seems more intens to develop AM based on pH changes. There is several things very interresting to me is that: 1) AM tension can be activated by magnet. 2) almost there is no permanent chemical structure changes in the material during it's usage. In other words AM have very long lasting endurance. 3) even it's reaction to the activating signal relatively slow, it's force strength to pull is very huge, because it's depends on strength of solid material used as AM itself. Based on those facts, i inspired to design "perpetual engine" using magnetic based AM The concept is very simple: -set two AM in oppsite position to pull each other. -use a magnet to activate one of the AM -use the motion created by AM to switch the magnet to activate opposite AM. (please take a look at animated gif attached). This picture is only concept to describe the idea. Real machine may have diferrent architechture. Of course the frequency of this machine should be set according to AM elasticity, response-time, and mass of each components. Notice that earth gravity is nothing to do with this device's works. The device shown in the picture attached should also works in horizontal position or any other position. Gravity will only 'annoying' this device if it stands vertically. Then we can take some benefit of power from it's back & forth motion between those two AM by other mechanism such as cam-gear (wich works as mechanical diode), or piston and valves, or else, to drive generator. I knew this device might be violent to thermodynamic law. So I like to hear some review from experts here, is this device can really works?
