It is actually the energy which isbeing extracted from the core ofatomic nucleus either though atomicnuclear fission or fusion.

Presently the nuclear fission ofelements in the actinide series ofthe periodic table produce the vastmajority of nuclear energy in thedirect service of humankind,with nuclear decay processes,primarily in the form of Geothermal--Energy, and radioisotopethermoelectric generators, in nicheuses making up the rest.

NUCLEAR FISSION AND FUSION REACTIONSFISSION PROCESS FUSION PROCESS

Nuclear fission is a reactionin which a large nuclei breaksapart into two smaller nuclei,releasing a great deal of

energy.

Nuclei can fission on theirown spontaneously, but onlycertain nuclei, like uranium-235 and plutonium-239, cansustain a fission chainreaction. bombfission.gif

In fusion reactions, twolight atomic nuclei fuse toform a heavier nucleus . Indoing so they release acomparatively large amountof energy arising fromthe binding energy due tothe strong nuclear forcewhich is manifested as anincrease in temperature ofthe reactants. fusion.jpg

1.Occurs only in special solids. 1. Occurs in plasma or whenenergy is applied.

2.Responds to modest energy but not required. 2. Requires high energy.3.Uses protium (H) or deuterium (D). 3. Uses tritium and deuterium4.Makes mostly helium (4He) when D is used. 4. Makes tritium and neutrons.5.Produces insignificant radiation. 5 .Produces significant radiation

6.Can be initiated in simple devices at high O/I levels. 6. Requires a huge machine to producehigh O/I levels.

7.Has been studied for 23 years using about $0.5 B. 7.Has been studied for over 70 years usingwell over $25 B.

8.Energy generators can be located in each home. 8.The energy generator is huge and mustbe located well away from populations.

The first cold fusion powerplant is now available to pre-order. The E-Cat 1MW Plant,which comes in a standardshipping container, canproduce one megawatt ofthermal energy, using low-energy nuclear reactions(LENR) , producing energy100,000 times moreefficiently than combustion.

Continued…Low Energy Nuclear Reaction Aircraft InvestigatorDoug Wells, NASA Langley Research Center

The purpose of this research is toinvestigate the potential vehicleperformance impact of applying theemergent Low Energy Nuclear Reaction(LENR) technology to aircraft propulsionsystems.

LENR potentially has over 4,000 times thedensity of chemical energy with zerogreenhouse gas or hydrocarbon emissions.This technology could enable the use of anabundance of inexpensive energy toremove active design constraints, leadingto new aircraft designs with very low fuelconsumption, low noise, and no emissions.

1.SAFETY-The major advantage of cold fusion reactorsis that it will not produce high-level nuclear wastes liketheir fission counterparts, so disposal will be less of aproblem.

2.ECONOMIC VIABILITY- In addition, it will becheap as Deuterium can be readily extracted fromseawater, and excess tritium can be made in the fusionreactor itself from lithium, which is readily available inthe Earth's crust.

3.CLEAN- No combustion occurs in nuclear power(fission or fusion), so there is no air pollution.

4.LESS NUCLEAR WASTE-Fusion reactors will notproduce high-level nuclear wastes like their fissioncounterparts, so disposal will be less of a problem. Inaddition, the wastes will not be of weapons-gradenuclear materials as is the case in fission reactors.
