Yes. Splitting water takes energy.
Step 2 gives you a more powerful form (a high energy neutron).
Ummmmm. No. Removing an electron from hydrogen gives you a free proton. Not a neutron.
Step 3, fusion of elements heavier than iron, is endothermic. No energy there either.
And what did this mean, "actually Four times as powerful as the average"?
but I bet that last action ~ "absorb neutron" and "spit out powerful photon" takes place instantaneously.
If you had said "absorb proton" and "absorb powerful photon", you probably would be closer to reality.
Remarkably in our merriment at discovering how to make really big atom bombs and hydrogen bombs, and doing the STRONG NUCLEAR FORCE thing we overlooked the WEAK NUCLEAR FORCE.
BTW, irrespective of "theories" on whether or not these guys are firing a proton or neutron out of the slot it's only guaranteed to be a proton if we have STRONG NUCLEAR FORCE processes at work and sometimes you are going to get your fair share of gamma rays if you screw around with it all that much.
Otherwise, it can be something else ~ and there you have it.
The Patent Office believes "something else" to be fairy dust and unicorns ~ not that that stuff is bad ~ in this regime you must sometimes believe in them in public after all. On the other hand the PO isn't going to give you a patent on 'em.
Really, 'splaining the functions/possibilities of THE WEAK NUCLEAR FORCE in terms applicable to THE STRONG NUCLEAR FORCE may or may not be useful. It may be nothing more than flipping a switch on an up quark so that it becomes a down quark ~ or maybe something else is underway.
May be a mission yet for the now mothballed cyclotron in Chicago.
