I will take an educated guess as follows: Because nickel which is a magic element works well, I would try the other heavier magic elements like tin and lead.
Lead would be the best because it is so heavy. The fission limit may be lower for tin and lead because the nucleus is so heavy. Contrary to common sense, maybe because the nickel is so well balanced, it is easier to unbalance it. Since I am speculating wildly, I would further guess that hydrogen is not important in the LENR+ process. Hydrogen does not bring much advantage to the table with regards to screening. If I had a Ni/H reactor to play with, I would try helium as a coolant instead of hydrogen just to experiment. cheers: Axil On Thu, Mar 28, 2013 at 4:15 PM, DJ Cravens <djcrav...@hotmail.com> wrote: > can you use your insight to tell what "fuels" would work best, instead of > what products are produced. > You have to get the reaction working before you can start looking for > products. > > > d2 > > > ------------------------------ > Date: Thu, 28 Mar 2013 15:11:03 -0400 > Subject: Re: [Vo]:thoughts on LENR energy > From: janap...@gmail.com > To: vortex-l@eskimo.com > > > Physics has seven magic numbers.
