Re: Addendum-DC Tesla

Hi everyone,
             I would like to congratulate Richard on an excellent 
series of experiments and some fascinating ideas. I'd also like to 
thank him for sharing this with me. The concept of charging the air 
with waves of ions is quite new to me. I don't think for one minute 
this affects the AC dynamics of the coil itself. But storing energy 
in the air in this fashion could certainly explain the discharges 
talked about. Permit me to inject a thought or two.
     If one progressively stores energy in this way, one final shot
would at some stage be sufficient to tip the balance as it were and
let the lot go. Is this how you see it Richard?

In effect I see rectification occurring through ion migration away 
from the terminal. I can see how a series of waves of diminishing 
amplitude can in effect rectify by leaving a nett charge in the 
ionized air. Is my understanding right here?

This would make sense if the phenomenon were dependent on the 
differing amplitude of successive waves, yes?

Please tell me if I misunderstand any of this. One thing interests me.
In the process of ionizing air around the terminal (ion cloud) there 
must be some recombination going on as well. When the coil is 
prevented from emitting sparks, is there any glow around the terminal?
