You need energy to do work but you can never use all the energy you have to do work no matter how good your technology is, much of it is always wasted. With today's machines usually less than 40% of the energy can do work; electric motors do better than that but you waste a lot of energy converting heat or motion or sunlight into electricity. > > > Yah! Now that sounds really, scientific, not. I refined the definition, to > be "matter in motion." The energy of motion is half of the mass of the matter times the velocity of motion squared. If it's at rest it still has energy, it's the mass times the speed of light squared. John K Clark -- You received this message because you are subscribed to the Google Groups "Everything List" group.
