Cold Fusion: The Continuing Mystery In March of 1989, a discovery was made that rocked the scientific world. Stanley Pons and Martin Fleischman had announced that they were able to create and sustain a cold fusion process. After intense media attention, and corresponding interest in future test, the subject seemed to have faded away. Future tests proved inconclusive, and when the quick promise of easy energy didn’t materialize, most quickly forgot the subject. Little is said about the continuing research in the scientific community to further our understanding of the free energy enigma. Is it science fiction, on the border of legitamete science, or is it a practical field worthy of serious attention? Cold Fusion is the merging of two dissimilar metal hydrides. The process is exothermic, and can generate energy in one of two ways. Energy can be input in to a system and multiplied, or energy alone can be generated although in a much smaller amount. For example, one watt of energy can be input and 3 watts recovered. Some systems are capable of producing hundreds of watts per individual watt. The actual physics of the reaction is not completely understood. Some claim it is merely a chemical reaction not yet understood, while others are convinced it is a nuclear reaction. One example is a cold fusion cell which used .04 grams of metal hydride. It produced 86 megajoules over a two month period. A similar chemical reaction would have required 2,000 grams of chemicals to produce the same amount of energy. Another interesting point regarding this cell was the fact it had to be deliberately shut down. There was no sign of the reaction tapering off. The skepticism regarding cold fusion stems from two separate studies, one done by MIT, and the other by the Energy Resources Advisory Board. The MIT study has been palled by attacks on the methods used to present the information. The chief science writer at the Institute denounced the study and resigned. The report contained altered graphs and an unclear method. The ERAB report was inconclusive, but presented to congress in a such a way as to present all of the negatives in order to maintain funding for their existed programs, instead of transferring research money to others.

This presents numerous gray areas in the understanding of the reactions taking place in the experiments. If indeed it is a chemical reaction then there is some flaw in our understanding of chemical reactions. The lack of nuclear byproducts when in theory there should be lends strong credence to this belief though. Only continued experimentation and new exploration will help explain the mystery. The use of cold fusion would be a boon to mankind. It’s use would solve all energy delimmas currently facing the petroleum dependant modern society. Elimination of pollution, economy, and ready availability of raw materials would be a tremendous improvement over today’s combustion engines and chemical cells. More so than any other alternative energy solution, cold fusion presents a source that is truly renewable and, if it lives up to it’s hypothesis, a large enough amount of power. No other means to date has proven it’s practical use on a large scale. Cold fusion could be the solution to the problems of global warming and pollution.
Introduction Fusion centers are easily described by their names. They are a collaboration between several different agencies that combine to form one united Criminal Justice front against terrorism. All agencies, such as the FBI, Department of Homeland Security (DHS) and local police, work together to analyze and gather potential information on threats and possible terrorist attacks against the United States. They also serve as a sort of hub to pass out information needed to other agencies. The creation of Fusion Centers helps make local law enforcement more capable in responding to and fighting terror threats.
Albert Einstein predicted that mass could be converted into energy early in the century and was confirmed experimentally by John D. Cockcroft and Ernest Walton in 1932. In 1939, Otto Hahn and Fritz Strassmann discovered that neutrons striking the element uranium caused the atoms to split apart. Physicists found out that among the pieces of a split atom were newly produced neutrons. These might encounter other uranium nuclei, caused them to split, and start a chain reaction. If the chain reaction were limited to a moderate pace, a new source of energy could be the result. The chain reaction could release energy rapidly and with explosive force.
In a fusion, two atoms’ nuclei join to create a much heavier nucleus.1 The two atoms collide and together make a new atom while releasing neutrons in the form of energy. Imagine this as two cars in a head-on collision. When they collide, they stick together (not forming a new atom like in nuclear fusion, but let’s pretend,) and when they crash, some of the bumper flies off. The atoms collide and neutrons, like the bumper, fly off in the form of energy.
Nuclear energy must be a consideration for the future with the rapidly depleting supply of fossil fuels. This type of energy can be created through nuclear fission and nuclear fusion. Nuclear fission is the splitting of a heavy atom into two or more parts, releasing huge amounts of energy. The release of energy can be controlled and captured for generating electricity. Nuclear fusion involves bombarding hydrogen atoms together to form helium. In the long run, nuclear fusion has greater potential than fission.
Currently, plants use fission reactions, which is the bombardment of atoms with neutrons to split atoms into new materials, releasing the energy which we have all come to rely on. Fusion is essentially the opposite of fission. Fusion is the combination of atoms to make new elements, what is happening at the core of our sun currently. When atoms are fused, a massive amount of energy is released, making the cost of producing nearly free once fusion is obtained. One other large advantage of fusion energy is the by-products produced by the chain reaction in fusion. The second most abundantly used power source in fission reactors behind uranium is plutonium. Plutonium could be created by the fusion reactions, giving people not only energy from the initial reaction, but even more fuel to use for fission reactors
"Science is sometimes blamed for the nuclear dilemna. Such blame confuses the messenger with the message. Otto Hahn and Fritz Strassman did not invent nuclear fission; they discovered it. It was there all along waiting for us, the turn of the screw" (Rhodes- 784).
Nuclear power is generated by using electricity created during a controlled fission or fusion reaction (“Nuclear Energy.” Global Issues in Context Online Collection). Nuclear fission is a process that releases energy when a nucleus in one atom is separated into two nuclei. Nuclear fusion occurs when the nuclei of two hydrogen atoms are fused together producing a larger nuclei along with energy (“Nuclear Energy.” Opposing Viewpoints Online Collection). In the 1950s, the use of nuclear power became a realistic idea for countries with nuclear capabilities and nuclear power programs (“Nuclear Energy.” Global Issues in Context Online Collection). The international nuclear program grew rapidly and by 1999 there were 436 nuclear power plants in 32 different counties. The United States, Japan, Canada, Russia, India and France remain the largest users of nuclear energy since the 1990s; however, the dependency on nuclear power varies greatly around the world because of differences in the individual nuclear power programs availability of needed resources (“Nuclear Energy.” Opposing Viewpoints Online Collection).
Despite the benefits of nuclear energy, another form of energy has been the status quo for decades. This form of energy is hidden...
Energy is created in a fusion reaction through the loss of atomic mass from the beginning to the end of the reaction. The mass of the two atoms is significantly more than the mass of the new atom, which they fused together to form. This loss of mass is subsequently converted into pure energy in the form of light and heat. The reason for this amazing discovery is that mass is just a concentrated form of energy. This understanding between the relationship of mass and energy was discovered by Albert Einstein and illustrated in his famous equation E=mc^2, where E is energy, m is mass, and c is the speed of light. Through this equation the amount of energy held within a mass can be determined. In a plasma fusion reaction between two hydrogen atoms the decrease in mass is about 4x10^-29 kg. This mass is then converted to energy, equaling 23.9 MeV. "To appreciate the magnitude of this result note that if 1g of [hydrogen] is converted to helium, the energy released… would be worth about $70,000" (Physics for scientist and Engineers 1276).
These are just 2, quite recent, examples of failures in the various different forms of alternate energy and shows that there is still a lot of work to be done to make these as safe as possible. However, despite these disasters, the research of these energy sources still goes on and it is very likely that they will be pivotal in the future.
Fusion power is inherently safer than other forms of energy generation, such fission, as well. As mentioned, fusion produces no long-term nuclear waste. I...
Nuclear Fission may be an unknown term to many, but it is right in front of us on the daily, powering our everyday life. This is a reaction which a large nuclei breaks into two similar but smaller nuclei. The Fission reaction releases a mass quantity of energy. The nuclei can naturally start itself into a Fission reaction on its own, but only certain elements can sustain a Fission Reaction Chain ei. (Uranium- 235 & Plutoni...

This level will be reach with free market and patents right, which will create incentive for scientist to make innovation. Hopefully, countries, in the future, will find co-operating relationship’ among each other and solve environmental problems.
Nuclear energy is generated by a process called fission. Fission occurs within the reactor of a nuclear power plant when a neutron is fired at an atom of uranium causing it to split and release subsequent neutrons.1 These are able to crash into other uranium atoms causing a chain reaction and releasing a great deal of heat energy.
