Diamond-Manufacturing Tokamak/Centrufige

Easier than fusion?
(+1, -1)
  [vote for,

I propose constructing a Tokamak to magnetically levitate/contain a six-foot diameter tungsten carbide trough. The trough would be filled with pure carbon, spun up to 500RPM (about Mach 9), and heated. Silica and iron would be added to the trough as well. The weight of the silica would compress the carbon between it and the iron, making diamond. The result would be hoops of pure diamond, useful for construction.

       Construction of what, exactly?   

       Diamond is pretty brittle.

       While you're at it, can you please explain how you're going to achieve the 50,000-70,000 atmospheres of pressure needed to create diamonds with this magical device?
UnaBubba, Feb 07 2013

       I believe the compression arises from the centripugal force. Quite how the trough is going to sustain that force is not made clear.

       Tungsten carbide melting point, 2870 C, diamond melting point 3550 C.

       [marked-for-deletion] bad science.
UnaBubba, Feb 07 2013

       But "Ferromagnetic behaviour has so far been observed in pressure and light polymerised fullerenes and irradiated graphite", so it might be possible just with the magnetic field of the tokomak and then you can dispense with the trough.   

       Do not ask me what will happen to the incredibly hot and rapidly spinning carbon circle if, due to a state change, it suddenly becomes non-magnetic.   

       [unmarked-for-deletion] as wonderful to watch, from a considerable distance.
not_morrison_rm, Feb 08 2013

       It would be wonderful to watch. I think a few tons of tungsten carbide fragments, re-entering the atmosphere, would make a lovely meteor shower.   

       Nice link, [hippo]. I also like the way [Max] created the neologism "centripugal", for the occasion.
UnaBubba, Feb 08 2013

       Very tempted to allow [Max] to take the blame for one further bit of vandalism of the Queen's English, as it is a thing he is wont to do; but this particular vocabularic anomaly is rightfully blamed on another - see link.

       how would it be cheaper/better than chemical vapor deposition?
Madai, Feb 08 2013

       In accordance with tradition, I shall endeavor to clear/muddy the waters of scientific truth as it relates to this idea.   

       The brittleness problem could be avoided by laminating multiple diamond hoops with a polymer, as in carbon fiber. Other more speculative methods might work as well (rapid cooling of very pure carbon to get amorphous diamond).   

       There would need to be a layer of Tantalum Carbide (melting point >4000C) between the tungsten carbide and the carbon/diamond.   

       You know what? This is a terrible idea. Here's a better one: take a big lump of pure carbon, put some silica rocks around it, put the block in the exact center of some fusion bomb(s), put it underwater (for rapid cooling), and detonate it.
sninctown, Feb 09 2013

       Yep. I'm pretty sure the people who live nearest to the cooling pond would welcome your idea with open arms.
UnaBubba, Feb 11 2013

       //open arms   

       All seven of them,due to the radiation.   

       Incidentally, howcome Spiderman doesn't have eight limbs?
