- ohiovr 4y agoIons in a magnetic field swirl in one direction while electrons swirl in the other. Metals when they are being dragged across a magnetic field form eddy currents that oppose the direction of travel of the magnet. In a wire a magnet traversing it makes one end positively charged and the other end negatively charged. In this respect, like charges seem to be concentrating when under the influence of the magnet. Is it right to assume the current is larger with thicker wire and more powerful magnets and the voltage depends on the relative speed of the magnet? A very short piece of wire encased in CVD diamond and further encased in borosilicate glass. The cavity is filled with fuel gas, the wire is also fuel. A powerful enough magnet, traveling at a fast enough rate could tear the metal down electrically separate its electric charges and when they gyrate they are blocked by the cavity. Diamond is the most atomically dense material with the highest breakdown voltage and also offers very good hydrophobic resistance. Perhaps if we could get the ions in one corner with enough electric pressure they would react.CVD diamond can offer a high degree of precision, and perfect seeds could be further grown imperfectly using high pressure solvent methods into larger, rougher, and tougher forms. A train car (for comedy relief I added a train) with a superconducting magnet on the side of it as it travels induces the magnetic field to concentrate the charges. The charges get bunched up in the corner of a diamond crystal, they have a little heat too, and wham-o, they fuse. Or just crack the glass. But diamond can keep back tremendous pressure. I haven't seen what kind of pressures are possible to obtain by using diamond cavities instead of extremities.
- FiatLuxDave 4y agoTrains are always good for comedy relief, or so I learned from Silver Streak. The problem with plasma containment is generally not holding pressure. The real problem is that plasmas which are hot enough to fuse have a really, really high thermal transfer coefficient. This means that if they touch anything, they want to give away all their heat to whatever they are touching. It is possible to do things quickly enough to have fusion happen before the heat leaks away (this is how inertial confinement fusion works), but that speed is way beyond train speeds. Quickly moving magnetic fields do cause high voltages, which can be used to concentrate charges. Most metals are not fusion fuels, so I'm guessing this wire would be made of lithium. The real problem with this idea is the part where the ions bunch up in the corner of the diamond crystal. What exactly is making them bunch up? The diamond? Realize that CVD works in reverse as well, and diamond is bound together with 3.7 eV bonds and we need a plasma of at least 15000 eV. Any plasma which is hot and dense enough to fuse is going to either be chilled too much by touching the diamond or go through it like a hot knife through butter.
- ohiovr 4y agoI should have realized that, thanks. After I posted that random thought I realized another which I think needed more time to flesh out but when I'm done would you like to read my report?
