Where is the electric light bulb that has been working continuously for over 100 years? The fire brigade in Livermore, California, has a 4-watt electric light bulb that has been operating almost continuously since 1901. It went out only a few times during power outages and twice when moving. Authors: Jimmy Wales, Larry Sanger Random interesting fact from the Great Encyclopedia: What is a perpetual motion machine? For hundreds of years, people have dreamed of creating a mechanism that, once set in motion, would continue it, performing useful work, while not drawing energy from an external source. However, each of the machines known to us requires an energy source. For example, the wings of windmills rotate using wind energy, while car engines run using the energy released when fuel is burned. The idea of a perpetual motion machine is that in the course of its work it must produce energy for itself. In other words, every time, making a full cycle, that is, returning to its original state, it must produce more energy than it consumed. Most people who tried to invent a perpetual motion machine proceeded from some practical considerations. They thought about how wonderful it would be if the mechanism pumped water or ground grain without requiring any energy. Is it possible to create such an engine? Any scientist will answer you this question in the negative, because the existence of such a mechanism would contradict one of the most important laws of nature: the law of conservation of energy. According to this law, energy in nature is neither created nor destroyed. Energy can change from one form to another, be released, accumulated or dissipated. However, it cannot be created, which means that any mechanism must have a source of energy. Throughout the history of mankind, thousands of attempts have been made to solve the problem of creating a perpetual motion machine. They began long before the law of conservation of energy was discovered. Even after this happened, there were many reports that such a device had finally been constructed. However, in each such case, the inventor's errors or simple fraud were subsequently discovered.
