*sigh* No... and you know what? Almost no ionic or metalic solid can block molecules as small as hydrogen (this includes all metals and metal oxides) nor can most molecular solids, and those that can are either too heavy, too brittle, or too reactive (will eat through) or otherwise won't work.

Diamond is as good as you're going to get. You can go through the entire periodic table and the answer you'll get in every case is no. You are simply pushing your system at a level where matter starts falling apart under the stress. There is nothing you can do about this.

Yeah diamond and aromatic carbon tops the list and they will probably react, plus there are not any perfectly crystaline polymers so plastics or other macromolecules won't work, and glasses or other similar covalents are too permiable.

Plus, diamond is the only material that has the necessary strength. Boron carbide might be up there too but it's even mroe brittle than diamond.

What are the biggest man made diamonds they can make?

Chunks the size of a quarter for almost-perfect, or thin films inches accross.

Not much displacement there. Need at least a dozen of them to add up.

Did I mention they are a mere fraction of an inch thick? You would need hundreds or thousands of them, and you can't "glue" diamonds together, they won't bond.

How is it they get 800,000 psi to make diamonds?
Offline

By focusing a modestly powerful hydraulic press down to an area the size of a pea and heating it up... and no, scaling it is up is not easy, and the time it would take to grow the diamond would inrease exponentially with size. Plus the number of pump-shattering defects too.
And even if you can make the diamond, you still can't make a pump out of it that will handle that kind of pressure because there is no known way to seal the joints.

Oh and they make big diamonds via a process called vapor deposition, but this is slow, energy hungry, and makes only fair quality crystals.

What kind of material do they use in the pump to get the 800,000 psi to make the diamond?
Offline

The die? Silicon carbide I think, but that asside, let me remind you... There is no practical material to make the pump from, no such material is possible if diamond reacts with high-press. liquid hydrogen, which I think it likly would.

Tungsten will work 400+Gpa does not react with H2 or Carbon.

Tungsten? 400Gpa? Sounds mighty high to me... and though it might not react with ultra-high pressure liquid hydrogen in question, I bet it still permiate, and make it crack.
Boom again.

If it is bonded to another supporting structure it won't crack. No boom.

I guess you aren't big on reading previous posts are you?
Tungsten is a big atom. Hydrogen is a small one. Tungsten atoms are roughly sphereical, and when packed shoulder-to-shoulder in its metal crystal has space between the atoms. This space is big enough for the little tiny hydrogens to slip past...

...and when you have enough of them, its like water into a dry sponge, it will expand and get flimsy. Unfortunatly tungsten is a metal crystal latice and not a chunk of porus rubber, and instead of expanding and retaining shape, it will just shatter on the atomic level and eat away at the surface of the pump.
Boom.

After how long?

At these pressure levels... hours, perhaps days. A few weeks if your lucky. A diamond press is a hours-to-days process, hydrogen diffusion should be pretty quick compared to the trace nitrogen diffusion in commertial gems.

So change it out, and put a new one in before failure.

Ummmm you want to shut down your tube, which means emptying out a pipe 200 miles long under extreme pressure full of a hyper-flamable gas... every few hours?
Mmmm. No.

Hey when you shut the pump off what happens to the 355,000 psi in the tube?

If you power off the pump, a little would boil off, but it would largely stay put. Though it would be under pressure, so it would still eat the pump material.

Ok before you shut it off you start the other pump. The pressure is gone now in the pipe because the top is open and exposed to the universe which is under a vacuum.

*smacks forehead*
Last I checked, there were eighteen pages previous to this one that clearly explain why the "vacuum of the universe" has not one single thing to do with the pressure of the liquids or gasses under Earth's powerful gravity well. NO, there is nothing magic about the other end being in LEO that will magicly suck out all the hydrogen, the pressure will remain.
I also really wonder if the Tungsten can handle these kinds of conditions in the first place.
