Good Work, Very Creative Imaginative, Good Explanation

For a fusion reaction to take place, the nuclei, which are positively

charged, must have enough kinetic energy to overcome their electrostatic

force of repulsion. This can occur either when one nucleus is

accelerated to high energies by an accelerating device, or when the

energies of both nuclei are raised by the application of very high

temperature. The latter method, referred to the application of

thermonuclear fusion, is the source of a lot of really cool energy.

Enough energy is produced in thermonuclear fusion to suck the paint of 1

city block of houses and give all of the residents permanent orange

Afros. The sun is a example of thermonuclear fusion in nature.

If I was a atom, I could only wish to be in a thermonuclear reaction.

Thermonuclear reactions occur when a proton is accelerated and collides

with another proton and then the two protons fuse, forming a deuterium

nucleus which has a proton, neutrino and lots of energy.

I have no idea

what a deuterium nucleus is, but is must be 10 times cooler than just a

regular nucleus. Such a reaction is not self sustaining because the

released energy is not readily imparted to other nuclei. thermonuclear

fusion of deuterium and tritium will produce a helium nucleus and an

energetic neutron that can help sustain further fusion. This is the

basic principal of the hydrogen bomb which employs a brief, controlled

thermonuclear fusion reaction. This was also how the car in the Back to

the Future movie worked. It had a much more sophisticated system of

producing a fusion reaction from things like, old coffee grounds,

bananas, and old beer cans. Thermonuclear reactions depend on high

energies, and the possibility of a low-temperature nuclear fusion has

generally been discounted.
