Original poster: "Jim Lux by way of Terry Fritz <twftesla-at-uswest-dot-net>" <jimlux-at-earthlink-dot-net> Isolated sphere capacitance is 114 pf/meter radius. Earth is roughly 6750 km radius, so 6.75E6*114E-12 = 769E-6 F, awfully close to the quoted 800 uF. Of course, you can also consider the gap between the surface of the earth and the somewhat conductive ionosphere as a cavity resonator, which like all cavities, has several modes (transverse, longitudinal, etc.) You'd also need to consider that it's a pretty leaky capacitor. ----- Original Message ----- From: "Tesla list" <tesla-at-pupman-dot-com> To: <tesla-at-pupman-dot-com> Sent: Monday, May 07, 2001 6:25 AM Subject: Re: Multiwound coil possibilities for Earth Resonance > Original poster: "Metlicka Marc by way of Terry Fritz <twftesla-at-uswest-dot-net>" <mystuffs-at-orwell-dot-net> > > Ed P., Bill W., Harvey N., All > question for you and\or all > > Tesla list wrote: > > > > Original poster: "Ed Phillips by way of Terry Fritz > <twftesla-at-uswest-dot-net>" <evp-at-pacbell-dot-net> > > > > Tesla list wrote: > > > > > > Original poster: "harvey norris by way of Terry Fritz > > <twftesla-at-uswest-dot-net>" <harvich-at-yahoo-dot-com> > > > > > > --- Tesla list <tesla-at-pupman-dot-com> wrote: > > > > Original poster: "by way of Terry Fritz > > > > <twftesla-at-uswest-dot-net>" <wysock-at-ttr-dot-com> > > > > > > > > Hello Bert, and all. > > > > > > > > I respect your question you asked below.
