• Hydrogen intake/pressure guage (or two separate valves)

• Stainless steel container• Resistive heating element

plate. Doubles as holder.• Nickel nano-powder with

Iron micro-powder• Waveguide with wire

hookups• Thermocouples?? Only if

Preparation/Notes• Waveguide feed integration is up to you.• Nickel: should be prepared via the wire blow-up

method we talked about in an inert environment. It’s tough to get Ni without oxidation. If the wire method is used parts of the pieces will be oxidized if the Ni wire was exposed to the air. Ni nanopowder should be between 3-20nm, preferably 3-12nm. Here is a possible link to buy it

• De-Oxidation: Heating it up as much as possible (but far below melting) along with the Fe and releasing the oxygen, flushing with Argon, OR use whatever method you like. I have little experience with this… then

• H2 Loading: seal copper canister and inject Hydrogen with 25 or so Atm at about 300 deg C and watching the pressure drop after something like 10 hours should do the trick. Should see sharp pressure drop-off at 200C.

• When pressure settles H2 should be bled off until 1 Atm. According to this we may even be able to go below 1 Bar/Atm

• Whether Fe is loaded with H2 or not should be irrelevant as we’ll have control versions so we’ll know if it is important.

• Feel free to add and modify and ping pong back with me

Variation Code

I mol of molecualar hydrogen (H2) is about 2 gram. 1 mol of nickel is about 59 grams. Rossi used 5 grams of Nickel so 1 gram of H2 and 5 grams of Ni gives us a particle ratio of about 12:1 for H:Ni. This means that we should have plenty of hydrogen for each nickel atom. I would probably start with something like this. 5 grams of nickel is about 0.56 cm^3. H2 volume at 20 C/1ATM is about 12200 cm^3 or 0.012 m^3. Chamber volume though should be something to structurally be able to handle 1 gram of H2 at say 300 C and have the accompanying valves and such. Id say the core dimensions will depend mostly on pressure and Roy's ability to put the necessary stuff on it. So that is more a Roy question. It should be as small as safely possible though. Less than 10% by mass of micron-Fe powder should be a good place to start so ½ gram.
