Nuclear Reactors and Batteries

Hydrogen fusion is a promising source of energy. They have made fusion reactors already. Though they aren't going to supply our energy needs because they consume more energy than the make. Fission reactors have been already made and are good at making energy. Unfortunately they have dangerous radioactive byproducts and wastes. Please post anything you want as long as it has something to do with nuclear reactors.

In a nuclear fission reactor how is the neutron fired at the U-235?

How is a neutron shoot into the fuel rod of a fission reactor.

Quadcopter Motor Type? Answered

Hi, I'm working on building a quadcopter.  I have everything figured out, but I'm wonder what motors (and where) I should get.  I would also like that motor to have a propeller mounted on it.  I have seen many Instructables for quadcopters, but none of them specify the motors/propellers.  If you could answer this, please do!  Thanks.

Fireball Bomb that works like an A bomb

This is an improved version of lemonie's Instructable Big explosion, bang, fireball, so hoorah to him for it. But any way, my idea is that I wanted to control the exact moment it went off, so this brought me to my first idea, just put black powder and a fuse in the lid of a butane can. Well this didn't work, I just got a jet of flame, plenty cool, but no fireball or musroom cloud. I realized I lacked the essential ingrediants of compression and rapid combustion. So I made this. It's literally a firing mortar for the can, the idea is a non-explosive shell (a coffee can filled with cement with a large bean can set inside to make an orofice) filled with an explosive, with the can of butane in the middle, and a cement stepping stone on top. The idea is that the explosive, when detonated, implodes the can, thus pressurizing it, then ignites the butane, thus decompressing it, A.K.A BOOM. The stepping stone by this point would have come of, thus allowing the expanding hot gasses to disperse. For saftey, the entire contraption would be put in hole in the ground, with no green grass growing all around. The reason I haven't tested it is that I had a very close shave with the cops for the butane can incendierary grenade. Disclaimer, I am not liable for what you do with this information, nor am I responsable for any damage to person or property, in other words, it's your problem if you kill your self. If you haven't yet noticed why this works like an A bomb, what in tarnation are you doing on this site? But, for credebility, I'll say. The main method of detonating a fission weapon is the implosion method. Prior to detonation a nuclear weapon consists of one or more pieces of weapon-grade fissionable material which are subcritical in configuration.The implosion method is when one sphere of material is compressed (through an explosion) to make it supercritical, which leads to a chain reaction, which results in the destruction of the atom, leading too duh, a big explosion.

The Future Of Nuclear Energy

p.MsoNormal, li.MsoNormal, div.MsoNormal { margin: 0.0in; font-size: 12.0pt; font-family: Times New Roman , serif; } p.Standard, li.Standard, div.Standard { margin: 0.0in; font-size: 12.0pt; font-family: Times New Roman , serif; } *.MsoChpDefault { font-size: 12.0pt; } *.MsoPapDefault { } div.WordSection1 { page: WordSection1; }                                              Nuclear energy is sometimes referred to as pollutant energy or “bad” energy. This is some what true but in the case of research  there is no “bad” waste being emitted from the reactions that undergo in theses reactors. Commercial Nuclear Reactors or CNRs do produce a lot of residue. They produce this residue by using their fuel so much to the point of radioactive waste. Small Research Reactors or SRRs do not do this, instead of using it up they produce new isotopes that can be useful instead of becoming waste.   So why don't we use SRRs? We do not use SRRs because of financial and safety. The safety concern comes in when the reactors are able to undergo Nuclear fission witch releases huge amounts of heat that no current materiel known to men kind is capable of withstanding. The other type of SRR is safe and financially friendly but does not produce electricity instead it uses approximately 1 million volts DC, but produces isotopes from elements such as Hydrogen witch is found in water.   In conclusion nuclear energy has not ended.

Scientists plan to ignite tiny man-made star

From"While it has seemed an impossible goal for nearly 100 years, scientists now believe that they are on brink of cracking one of the biggest problems in physics by harnessing the power of nuclear fusion, the reaction that burns at the heart of the sun.In the spring, a team will begin attempts to ignite a tiny man-made star inside a laboratory and trigger a thermonuclear reaction.Its goal is to generate temperatures of more than 100 million degrees Celsius and pressures billions of times higher than those found anywhere else on earth, from a speck of fuel little bigger than a pinhead. If successful, the experiment will mark the first step towards building a practical nuclear fusion power station and a source of almost limitless energy. Full article.This is big medicine, because while we have (more or less) successfully harnessed the power in nuclear fission, we've yet to find a method of using nuclear fusion for power (outside of experimental/weaponry uses). It is important to note, however, that this initial experiment, while big, won't be powering your home or office just yet-even if it does work, there's still quite a lot that would have to be done to build a nuclear fusion power plant.Still, it's heady stuff, the energy source of dreams-a world powered by nuclear fusion fueled by hydrogen, one of the most abundant elements in the universe-only now that dream is looking like it could, possibly, maybe, eventually, become reality.And now, a word from our sponser resident particle physicist:The NIF at Livermore uses small (BB-sized) pellets of liquid hydrogen (technically a deuterium-tritium mixture) encased in a shell. The pellet is illuminated by a terawatt laser split into 192 sub-beams all focused on a poiint. The outer shell of the pellet is vaporized and a shockwave compresses the hydrogen to the point where it should start fusion.The whole process is over in roughly a microsecond. If you keep dropping pellets into the chamber, then you get a series of pulses, but as soon as you stop, everything shuts down.The NIF (like the NOVA laser before it) is being run at a weapons lab, because the kind of fusion it can do (individual microsecond pulses) is most useful for studying the physics underlying thermonuclear weapons. It is probably not a viable technology for continuous power-generation fusion, but it is necessary for understanding how to make that sort of system work.
