Bene, me356 ha raggiunto importanti risultati nella comprensione dell'ottimale conduzione del reattore e ottenere il COP che vuole. Questa "scoperta" può essere realmente la base per più facili repliche. Ecco il messaggio, scusate la lunghezza ma merita un'attenta lettura:
"I am still very busy, but I have tested brand new induction heater and it works quite well, but for higher power it needs water cooling. I have also made circuit for regulation so the temperature can be controlled quite well.
Another experiment that I am doing is to find exact reason and behavior of the pressure inside the reactor.
Because I am convinced that there are at least two separate processes I am playing only with Lithium + LiAlH4. This allows me to exclude Nickel as possible reason for pressure changes so I can focus just on these compounds.
Result: I was able to change the pressure on demand +/- 5 bars only with the temperature - this is the key process to boost excess heat - it is not initiator of it, but only accelerator. This process is happening around 700°C.
First process that I am talking about is Excess heat from Ni + H reactions. From this process you can get probably COP of around 1.2.
Second process is LiH composition and decomposition. With ratio between Hydrogen and Lithium you can control the rate (how fast you can change the pressure, respectively how fast LiH can be composed/decomposed).
2 Li + H2 → 2 LiH
The higher rate mean higher COP.
If I understand it correctly, when you combine these two processes you will get excess heat of virtually unlimited COP. COP of 6 should be still very safe.
This process can be possibly replaced by pumping the hydrogen from a tank, but it can be dangerous and more prone to mechanical failures.
Because of Lithium, we are interfacing a big problem that it reacts with many materials, especially Alumina!! Thus the second process will fail mostly even before it can happen. This leads mostly to a breach and hydrogen escape + contamination of the fuel.
What I highly recommend is to not use Alumina tubes or to use a proper fuel container. I have observed that Lithium will react in irreversible way and as soon as it happens the experiment can end.
The conclusion is very important for all replicators - until you are unable to control the pressure, you can't get noticeable excess heat. If you can control it well, you can get very stable reaction.
As I said earlier, it should periodically breathe. Constant pressure changes are also demanding for used materials, so there are many, many reasons, why the replication is so hard."
