This is a common problem in the semiconductor industry with silane and large molecules that contain silicon.
so what was/is the fix for protecting working parts from deposition of unwanted materials.
Methane or acetylene seem like good choices as carbon is inert but very messy in terms of vacuum as carbon holds onto everything. Black powder all over the place isn’t very appealing either.
carbon will conduct electricity…. just take a pencil and draw lines from any 2 points on your distributor cap and run your engine. it just won’t be the same. I am still excited to see decaborane or alternative boron fuel introduced.. science is fun.
since boron is used in glassware could it be formed into strands much like glass fiber? I have a boron fiber fishing rod so i believe the same concept could be implemented.
could a small hole be drilled in the center of the anode and wedge some boron filaments in it for a test with just hydrogen gas.
If decaborane is used for trials this means that fouling will likely occur as the chamber temperatures are at room temperature. I was wondering if a solid fuel rod of solid boron was placed in the area of plasmoid formation that it could supply as much boron as required. since the plasmoid has lots of little electrons whizzing about and little hydrogen ions zipping round and round they could crash directly into a stationary object. I had an idea of a mechanism like a mechanical pencil with a boron filament that could be replenished by a little click if you wanted more, just protruding through the end of the anode. a kind of fusion fuel dispenser. this way the only gas in the chamber would be hydrogen and hopefully a growing amount of helium. boron has a high melting temperature so with a billion degree electron stripping off a few boron atoms or fusing on the side of the filament you will not have a noxious fouling gas to contend with. I believe the fuel density would go up considerably into the solid realm without having to change many parameters. in this way the hydrogen gas pressure would be the only parameter to adjust. that is if the plasmoid doesn’t care if it has a boron stick in one end.
I know that as the work is progressing and plans have been made to use decaborane, is there a material that could be painted on or used as a liner in order to make it easy to clean the chamber after testing? maybe some sort of liner or spray on non stick cooking oil? lol..
also note that this is mainstream fusion attempts not any worthwhile mention of boron or alternate fuels.
Yes he can do the math but needs to do more research. Iter and nif are nice science experiments but there are other unexplored avenues. Iter (i took everyones rations) will not prroduce Q + (not in forever) nif was never built to produceQ+. Dont allow anyone to crush the dreams that could change the wotld. Explore every avenue before admitting defeat.
somebody needs to go first….. I pledge to bring fusion to the discussion (primarily focus fusion) every time someone is talking about: wind, solar, geothermal, tidal, hydroelectric, nuclear, hydrogen, corn ethanol, peak oil, fracking, gas prices, electric bills, gas bills, smog, water desalinization, space travel……..
yes i understand that the images were from multiple shots. I guess the crux of my thoughts was that the shift seemed to move away from the anode and I was interested to know if during the travel it was heating new gas as it went or if it was movement of the gas that was already in a plasma state. if the plasmoid was stationary in free space would yield be higher? if the fusion reactions happen sooner than it appears to shift would more reactions take place if it didn’t shift. of course i know that magnetic interactions occur and force things in different directions but it occurred to me that if the anode were another set of rods that had less magnetic interaction results could be different.
remember that the internal combustion engine was refined from steam engine theory and that it came before turbine engines. it seems logical that an intermittent pulse power system would come before a continually powered system. focus fusion vs tokomak.
would it be worth investigating a pre ignition system for each pin by a small plasma current path that is pre initiated before the shot?
rather than hoping that each rod successfully establishes a filament, create the filament. the main shot would follow the small plasma line to each rod ensuring symmetry, it may in fact relieve the hat insulator from being subject to high currents along the sides.
it would also be useful in turning on or off a number of rods to find a suitable combination. a high voltage flyback transformer for each pin could easily control a small streamer with a small insulated electrode close to the center electrode. just a thought.
Is it my imagination? I have watched the animated snapshots of fofu1 plasmoid formation hundreds of times now and wonder why the bright spot in the middle(plasmoid) seems to jump up by at least its diameter. is this a magnetic reaction with the center electrode? hot gas pressure? if the geometry was changed would that keep all of those hot ions in one spot? it seems to me that if it has heated the gas in that area enough to glow that energy is lost during the shift away from the electrode.
wouldn’t it be great if Obama had the balls to put a fusion goal out like John F Kennedy did with the man on the moon mission? hopefully his replacement will.
interesting paper.
the paper speaks mostly of redshift from plasmas. only in the last few pages does it contend with magnetic disturbances and light interaction. it seems to me that the redshift from magnetic interaction would be less uniform in that magnetic anomolies are generally not very uniform. knowing the difference from magnetic and plasma redshift would be the trick in quantifying either.
you cannot easily disect the universe without encountering interactions from other processes.
Dow corning 1540-20p is a pourable silicone that can be formed in a mold any shape. Mix it with alumina or other insulator dust and you have a tailor made insulator with a lot of flex, insulating properties thermal capabilities, its off the shelf and inexpensive. 1 mold can make as many as you need and can easily be modified. Samples are easily obtained and would most likely cover the first few trials.
insulator cracking caused by mechanical stresses can be relieved by increasing clearances and insulating the insulator with flesable element (O RING) or by decreasing the stress applied or by changing the location of the stress. much like applying a large force on a window pane well supported or applying the same force on a poorly supported pane will render a different result.
from what i understand the material must comply with several operating parameters.
1 capable of 100 to 200 KV dielectric strength at low frequency for now.
2 capable of exposure to high temperature plasma
3 capable of exposure to high intensity xrays/ gamma rays / and the occasional neutron bombardment.
4 mechanical stresses both loading and thermal.
5 inexpensive and readily available
it sounds as if the chosen material is suitable in many aspects but application needs reconsideration.
if all things are equal there shouldn’t be shifting of side loading of any part of the machine.
if there is a push to the side i think this may lead back to asymmetric firing of the filaments.
if the insulator is properly supported and equally loaded it should not break.
if the insulator is fracturing at the joint between the flat plane and the cylinder it seems likely that there is a side force acting on the inner cathode.
if the insulator is fracturing at the edge is is coming in contact with conductor plates and flexed out of plane. if the edge shows signs of thermal shock it is likely from flashover.
in my opinion keep the existing material and support it differently.
Run it hard find what breaks build that steonger repeat.
just a thought on the axial coil imparting some spin to ions…. do the perimeter conductor rods need to be symmetrical in length or could a variation in length cause a similar effect by allowing some filaments more (or less) energy just before filament separation and pinch? would stronger filaments force ions to one side and squeeze them through the weaker strands? or force them together while still contained within the pinch? I’m sure some vairations have been experimented with but I haven’t been able to access any data on this idea.
btw. what is the final disposition of fofu 1 once the experiment is complete? and where do you stand as of today on feasability of pb11?
