Was that separating the deuterium and tritium from natural water?
Deuterium and tritium can be made in power reactors. The core of power reactors can be seeded with special rods to make deuterium and tritium thus cutting the cost dramatically.
There are no free quarks. Not a pun. They come in three’s.

Use metallic hydrogen if it can be made in a practical process, and if proven sufficiently stable. Kilogram of TNT is about +4MJ. A kilogram of metallic hydrogen has a molecular hydrogen recombination energy release of about 216MJ, before any other secondary reactions occur—a better than 50 to 1 improvement.
An eccentric billionaire decides to sterilize his 106-liter swimming pool by the water in it. For heating purposes he uses the fusion reaction
1H + 3H -->4He + radiant energyAssuming the heating system is 20% efficient, how much does it cost for the tritium (3H) to raise the pool temperature from 20 to 100°C? It takes 4.2 joules to raise 1 g of water through 1°C. Tritium costs about $5 per cm3 of gas at STP.
Atomic masses:1H 1.0081 amu
3H 3.0170 amu
4He 4.0039 amu

Your pings are always welcome. Wouldn’t have seen this if you hadn’t pinged me, so thanks!
Just now realized that, in my post 64, I actually provided the proper distance unit for a Joule within a quote that I found online, but didn’t catch until now: meters, as opposed to km.
Post 64:
“A joule, symbol J, is a derived unit of energy in the International System of Units. It is equal to the energy transferred to, or work done on, an object when a force of one newton acts on that object in the direction of its motion through a distance of one meter (1 newton meter or N-m).”
My pleasure!
Sounds like a job for Tech Insights.
..all the way to China?>>>>>>>
Just in time, LOL.
But first you have to make your shiny kilos of metallic hydrogen. Hint: it involves high pressure, about 5m atmospheres. The pressure at the earth's core is only about 3.6m atmospheres.
And, having achieved that, you then have to package the stuff into a deliverable weapon without you, the user, or anyone in between suffering a work accident. Good luck.
What you want is 72.6*c*c = 6.5249626 × 1018 m2 / s2, or that many joules. Given 4.18e15 joules per megaton, we are left with 6.5249626e18 / 4.18e15 = 1561 megatons for the energy equivalent of 160 pounds.
As a check on the above, see http://www.1728.org/einstein.htm. Plug in 160, select pounds, and it computes 1559 megatons.
Your calculation implied a much higher mass to energy for a one megaton bomb than I remembered quoted, so I checked. The actual mass converted in a typical warhead is fairly trivial.
Not sure I completely understand what you're saying, at least not yet, but you seem to be saying that a 160 lb person yields the equivalent energy of 1,559 megatons of TNT. Is this correct?
I had initially, and mistakenly, used the units km instead of meters and came up with ONE megaton (1 million tons) of TNT. Then, when informed I was off by a factor of a million, by using km instead of meters for "c", the speed of light value in E=mc^2, reduced the final figure by a factor of a million to ONE ton of TNT. But now you're saying 1,559 MILLION tons of TNT??
Yes.
My 1561 number was a little high because I used 72.6kg for 160lb. The correct conversion is 72.5747792kg. Plugging that value in, 72.5747792*c*c / 4.184e15 = 1558.96173 megatons, the value the 1728.org page calculates.
Little Boy's yield was estimated at 21.5kt. Working backwards from energy to mass, 21.5*4.184e12/c/c = 0.00100089548kg, about the mass of a paperclip. The death toll was estimated at 140,000.
Ivy Mike yielded 10.4mt, converting 10.4*4.184e15/c/c = 0.484154095kg, a little over a pound. Dr. Teller was watching the seismograph in a Berkeley sub-basement. When he saw the squiggles, he surfaced and wired Los Alamos, "It's a boy!"
I do not mean to be offensive, but think you are fundamentally confused about mass-energy equivalence. The issue is more subtle than you seem to appreciate. The old text “Special Relativity” by A.P. French might help clear some issues for you. It takes a lot of work to get through, but it’s worth it.
Ivy Mike, Little Boy? Who are they?
Little Boy was the U-235 gun-type bomb dropped on Hiroshima. It was the second nuclear bomb ever exploded. The first was the Gadget, a plutonium implosion-type design, tested three weeks earlier at Alamagordo. And, of course, the third was Fat Man, the implosion-type bomb dropped on Nagasaki.
The bomb's designers knew the plutonium implosion design was superior to the simpler uranium gun design, but the implosion design was also the greater engineering challenge. So, as insurance, they developed examples of both. They were so certain that the gun-type bomb would work that they never tested it.
Lol! Thanks. Somehow this is the first time I’ve heard of that.
