Looks familiar?

Another methode to get para hydrogen from orho.....

Pretty cool but where goes the heat?

I havent found out, yet.
The funny thing is that this design is exactly the gasprocessor of Meyer....
That also would make sense.
Electrolysis makes ortho hydrogen.
You cannot run a car on ortho. Para is used. It burns slower. Thats what Stan always said. Slowing down burnrates.
Of course you can add steam to the process. Carbon tricks can be pulles as well.
But Para is what you need. I am pretty sure of that fact.
If you start searching on how to change ortho into para, it almost always come to cooling the gas down.
But with minus 18 degrees celcius you simply do not create the most para.

Their comes the gas processor in place. Meyer fouled us again.

EPG?
Here i come.....

it is evident that the speed of conversion depends on the product of the transition frequencies and the waiting time. The frequencies are given by the energy differences in the Hamiltonian, which depend on the inter- and intramolecular dipolar interactions. Thus an efficient conversion will appear after times determined by the inverse of the dipolar interactions. Moreover while the amount of created ortho-H2 will initially oscillate, these oscillations will die out after a phase relaxation time T2 and a stable finite value will be found, which is determined solely by the diagonal elements of the density matrix.
