Re: Hydrogen gap

Mike,

>From what I have read about Poulsen arc oscillators, if you don't use very
strong magnets to quench the arc, or arcs in your case, you will not be able
to get oscillations much above the audio range.  I think it will be quite an
engineering feat to design a magnet which will provide the proper magnetic
field for all of your gaps.  Possibly you should start with just one gap to
experiment with, then try adding more.  But it sounds fascinating - keep us
posted!
