I guess

I think that's the only bit you got right.

[Kryptid]

So the nucleus of the atoms 1-8 become less dense each time they fuse.

Do you have data to back up that assertion?

[trevorjohnson32 (OP)]

the four  energy conversions of an explosion are sound waves, seismic waves, weight displacement, and heat. Perhaps we over look weight displacement as a possible clean fusion technique

By making the container for the hydrogen bomb thicker it would be cleaner I think. but all I can think of for a weight diplacement idea is dropping a heavy weight and a generator, or at what speed you would have to propel something like a rocket that at escape velocity enters into a tube in the earth and at a deep level inside a container and then crushes a hydrogen pellet, the rocket head loaded with steall and explosives to blast the steel like a cannon into the pellet. What about that idea ?

[trevorjohnson32 (OP)]

Maybe if you had like 1,000 cannons and the cannonballs crash at the center,just think of it eventually you would get fusion with that technique, by blasting each ball into a lever it could pull up on a container to provide pressure.

[Kryptid]

What about that idea ?

If it was going fast enough, that would work. But then you'd have to figure out how much energy would be necessary to make that happen and compare it with how much energy you'd get out of the hydrogen pellet. How you'd capture and use that energy would be yet another problem, since it sounds like you are creating conditions that would destroy everything in that device.

Only if they were moving much, much faster than typical cannonballs. They would have to have enough energy to completely vaporize into a multi-million degree plasma upon impact.

I'm thinking a square cage in a sphere shape where each cannon ball compresses water in a square of the grid. Then have a blast force in the center that compresses the grid from the other direction when the cannonballs hit. the increase in squares of the grid vs one cannonball crashing into a second, and the usefullness of the many cannons is the grid becomes tighter at the added cannons. The grid could then be highly prssurized with fusion fuel.

Also perhaps by heating the fuel to a plasma level while simultaeounsly crushing it with pressure from the cannon ball idea or with lasers, you would have double the shot at detonating it.

cannons are like 40 efficient to weight dispalcement

Autoignition point of selected substances
Substance   Autoignition
Diethyl ether   160 °C (320 °F)
Ethanol   365 °C (689 °F)
Gasoline (Petrol)   247–280 °C (477–536 °F)
Hydrogen   536 °C (997 °F)

It seems like they could heat the hydrogen fuel pretty hot in any setup then use pressure to crush in the 996 degree hydrogen fuel. You could probably build a lot cleaner fission powered explosives by having the fuel already at high pressure and temperture as well as building the case thicker so the reaction is more localized to the inside of the explossive.


Question does the hydrogen fuel that burns

[evan_au]

perhaps by heating the fuel to a plasma level while simultaeounsly crushing it with pressure from the cannon ball idea or with lasers, you would have double the shot at detonating it.

It has been tried, with 192 lasers aimed into a spherical chamber.

Do you think you could focus your cannonballs down to < 1mm diameter?
- Or achieve a density 100 times greater than lead?

To produce steady power, you would want many fusion pulses per second.
- So far, they are struggling to generate more than a couple of pulses per day.
- But it is still an interesting research tool.

Maybe if you had like 1,000 cannons and the cannonballs crash at the center,

Then you would distribute the energy among 1000 cannonballs worth of matter.
The energy density wouldn't be higher than if you just fired two cannons at each other, or just fired one cannon at a wall.
If your idea worked we would have discovered fusion about 800 years ago.

Why do you think the temperature at which something catches fire in air is remotely relevant?
Of do you not understand that the word "ignition" has more than one meaning?

Shouldn't you have found out about that before posting?

[trevorjohnson32 (OP)]

Why do you think the temperature at which something catches fire in air is remotely relevant?

They could heat the fuel up to a temperture just before it catches fire, this would reduce the amount of fission you would need to use to achieve fusion because their would already be heat enegy and pressure in the fuel instead of chilled like you read about.

[trevorjohnson32 (OP)]

It might help to use hydrogen fuel as the primary and the main part of the fusion fuel, then its already blowing apart and highly pressurized, you could layer it out from the center as Hydrogen fuel that is the primary AND tertiary explosion and because of the added pressure from being both would lessen the kt of the secondary fission.

[trevorjohnson32 (OP)]

Do you see what I'm saying if we combine different forces of an explosion: weight displacement for pressure, and heat simultaneously to the fusion fuel it would be more reactive I think.

[Kryptid]

It wouldn't be remotely close, though. It would be like try to speed up the process of cooking a turkey by warming it with your palms for a few seconds first. The hottest flame that we have been able to produce through chemical means is just under 5,000 degrees Celsius. The temperature required for fusion is millions of degrees Celsius.

If there isn't any air present, you don't need to consider fire.
And since oxygen and nitrogen are more difficult to fuse, having air present would just dilute the reaction you are hoping to produce.
Fundamentally, you are trying to heat the bathwater with only a single match.
It isn't going to work.

Do you see what I'm saying

Yes. We see what you are saying.
Why don't you see us saying that it will not work (and, indeed, that it did not work the first time someone shot a cannon at a wall)?
Why do you insist on ignoring facts?

It would have to work at some point.

cannonballs work great for simple examples. By converting an explosion into a weight displacement you can add sudden explosion of pressure to a system rather then just placing the explosive in the system which would be ineffeicient.

[Bored chemist]

No it wouldn't.
We can do maths on this if you like.

rather then just placing the explosive in the system which would be ineffeicient.

Nobody is saying that you can start a fusion reaction with a conventional explosive. Efficiency isn the problem here.
It just isn't hot enough.
There isn't enough energy packed into the material.

Why are you saying this will work.
It's like trying to cut through steel with a knife carved from a potato.

I'm saying the benefit of the hydrogen fuel acting as the primary is that it would put the hydrogen fuel in a state where it's more ready to be fused, this causing a lesser amount of fission to ignite fusion.
