    Does anyone know about the recent developments in wireless power (i.e. when the resonant frequencies of two distant electric circuits match, power is transmitted. sorta like a long range transformer)?

    If so, do you think we could power something using the Earth's electric field, if the device we wanted to power was set to the Schumann resonance?

    maybe my physics is a bit sketchy in this area, but does the earth having a magnetic field necessarily imply that it has an electric field as well ?

    A lot of the energy of the magnetosphere goes into stopping solar particles. High energy particles in the exobase are constantly diffusing along the field lines and being lost to space.

    The Earths magnetosphere has decreased in strength by 10% since measurements began in the 1830s, this is about 20 times faster than models indicate that the field would decline naturally if the geodynamo was to shut down.

    It requires an alternating magnetic flux to induce a current. Besides that, the earth's magnetic field is very weak.

    i thought the earth did have an electric current to it. what are Telluric currents? and don't they oscillate?

    When one winds many miles of magnet wire and monitors the Schumann ELF frequencies, an apparatus can be powered to follow the oscillations. However, any net gain, after e.g. charging the batteries of the chart recorder and the magnet winding motor, seems to me dubious. :?

    Whether some kind of tuning to a resonance circuit would be more efficient might be another matter. The Schumann resonances are worldwide and essentially incessant, a highly energetic ringing of electromagnetic bells forever pinged by lightning bolts. Tesla, who actually first observed such oscillations -- not Schumann (who did first correctly identify and approximate their resonant aspects), was interested in transmitting power with them, but was financially ruined in the effort.
