Zero Point Energy: Energy from nothing?

                           Over the last few decades scientists dreaming new energy source cheap, safe -powered, is also guaranteedly pollution, and overwhelming. Is it possible for this energy can be realized instead of a vacuum?
                           At around 17th-century who holds a vacuum to make is enough to suck who fill out all the material room was that in this case is the molecular air. Then in the 19th century people realize in a vacuum that is made in this way, will still remain thermal radiation, which is caused by the difference radiation high temperatures. To eliminate thermal radiation, just cool room temperature absolute zero was in. In theory, the temperature is no thermal radiation and all these particles will live and pool will be empty of particles that milled about.
                          But the result recent research shows it would be a new one . In a vacuum as above there are still radiation that is still there are even temperature has been sent down to absolute zero. Radiation is called the " zero point radiation", it bears as it was in accordance with nature that is still appeared in temperatures absolute zero, and energy its power plants is called the " zero point energy" (ZPE).

           The ZPE indeed has been estimated theoretically in the theory mechanics Quantum. Paul Dirac Statistics, one founder of the theory of the mechanics quantum, has been a vacuum suggested that truly inside it contains high-energy particle negative. New concept this nurture that "empty physically" is not completely empty handed. Quantum Mechanics predicted that these particles could not be seen this can be changed exist to real matter in a very short period of time and produce style that can be measured. The statement Dirac Statistics above is one of the uncertainty principle the implications of that is claimed by a scientist at the German archaeologist Werner Principle at the end of 1927. This principle at the core said that it is impossible for we know in science all property owned by a particle on one-time but will always be there is uncertainty in a certain amount. For example, we could not understand position and velocity particles both in science. The more accurate we measure speed a particle, his position is getting inaccurate, and so too instead. Uncertainty is applied in general, does not depend on the method and instrument that is used, and cannot be avoided.

           The uncertainty principle of quantum mechanics and is that there is a fundamental phenomenon that cannot be is predicted by the laws classical physics. For example: classical physics, according to the law a pendulum swings slowly will slow swings because friction and finally live article focused to recognize these delicate balances. In theory quantum mechanics, pendulum will not be never actually be lived in the equilibrium. Pendulum will always swinging randomly around the kesetimbangannya. These random Movement due to a phenomenon that is known as quantum fluctuations. But practically is very difficult to observe quantum fluctuations in things like a relatively large pendulum hours. Quantum fluctuations which have been observed in the matter of atoms or electron shells.

                 ZPE is the result of quantum fluctuations that occur randomly from a vacuum energy as foretold by uncertainty principle Principle. In that case the above, energy that cause hanger to move around the silence is ZPE. Although ZPE in the case above is very small. But there are so many possibilities propagation mode that penjumlahannya will produce ZPE is very big . In some cases, fluctuation that there should be big enough to create particles spontaneously from emptiness, although it will eventually be cut off again before violate uncertainty.

        From all the phenomenon fluctuations zero point, fluctuation of energy elektoromagetik which is very easy in detecting and measured. One of the eksperiment that has been done is known as the stock exchange Casimir (in take from the name scientists, who was first found it, Hendrik B. G. Casimir), this effect showed that there are two plate metal nearest to each other in a great distance are very, very close (in the range around one per one million meters) will arise style each other interesting between the two plate . This style is still appear even in a vacuum absolute zero and at high temperature, to be evidence of the ZPE.

         ZPE in apparently played an important role in various other phenomenon. Why gas helium cannot be frozen (helium is the only one element that could not achieve solid despite temperature phase absolute zero) was suspected to be made ZPE is the cause. Some other research found an anomaly physics that was suspected to be the result of energy conversion from ZPE. The physicists also try to connect the gravitational pull and electromagnetic field as the implications of ZPE.


      Then the question is, How big potential ZPE? Two scientists, Richard Feynman and John Wheeler calculated that energy from the vacuum size bulb , can have a lot more than enough energy to vaporize all the water in the ocean. It is the potential of this is very big. The challenge is how tap into energy of the to be utilized. If human beings are able to create technology ZPE, the energy crisis will be solved and environmental destruction caused by pollution from its use fuel oil, or nuclear waste can be eliminated. Even if it's not it is impossible for a human being able to go to explore space with the machine ZPE. It is amazing !
