Man, I don't know, Dave. How long have they been selling those carbon balls for that purpose?
I don't have the figures in front of me, but carbon has a significant amount of resistance. (Maybe that's the secret: the current gets limited as a result. :-) It would be interesting to calculate the resistance of a carbon sphere sometime (how big are those?). Then we could roughly estimate the voltage drop across it and so come up with a ballpark figure of the instantaneous power dissipated in those balls. At that point, someone with way too much time on their hands could estimate the temperature rise based on the specific heat of carbon. :-) 73, Mike www.w0btu.com On Fri, Jul 27, 2012 at 2:42 PM, DAVID CUTHBERT <telegraph...@gmail.com>wrote: > www.rossengineeringcorp.com/toroids_spheres_corona_nuts.htm > On Jul 27, 2012 9:43 AM, "DAVID CUTHBERT" <telegraph...@gmail.com> wrote: > >> <http://www.rossengineeringcorp.com/toroids_spheres_coronary_nuts.htm> >> >> Ross recommends carbon for lightning. >> On Jul 27, 2012 9:33 AM, "Mike Waters" <mikew...@gmail.com> wrote: >> >>> I don't think carbon balls are suitable for lightning protection.
