Nazi engineer and Disney space advisor Wernher Von Braun helped
give us rocket science. Today, the legacy of military aeronautics
has many manifestations from SDI to advanced ballistic missiles. Now
there is a controversial push for a new missile defense system. What
will be the role of missile defense in the new geopolitical climate
and in the new scientific era?

The earth is a leaky capacitor -- and a lousy, inconvenient one,
with high dissipation and resistance, if you're trying to move
energy in or out. Rock and dirt have such high resistance, that
getting usefully concentrated power though them would be very
difficult, even if it were thermodynamically possible.
I could take some time, go to a thermo text, and show that the
availability was 0, or trivially small in terms of what would need
to get USEFULLY CONCENTRATED energy from "the earth as a capacitor."
But talking to you, that would seem to be a wast of time.
What does this have to do with Missile Defense? Are you
suggesting that all these years, all these scientists and engineers
working on nuclear energy, or fusion, or squeezing the last tenth of
a percent of efficiency out of electric generation systems, have
been missing something big, that Tesla got to be hugely successful
by accident, and then abandoned?
On the one side, you and dirac are saying that technical
people are miracle workers, who can, in secret, perform feats far
beyond anything anybody has done in a verifiable manner.
But at almost the same time, technical people are dolts, in
You say these same technical people have missed a huge, easily
tapped energy source?
I don't have any reason to believe that technical people are
either that good, or that bad.

In his "World System", Tesla did not comtemplate beaming power
through the Earth. He contemplated the transformation of naturally
occurring currents of extremely low frequency into horizontal
The surface currents that Tesla contemplated will not reach the
ionosphere due to the high resistance of the atmosphere, a desirable
feature of the Earth capacitor. Rock and dirt offer practically no
resistance to electrical currents of extremely low frequency.
All capacitors leak. Most forms of lightning do not reach the
ionosphere and are not evidence of leakage in the Earth capacitor.
The leakage of the Earth capacitor occurs during Auroral events. If
the energy of an Auroral event lasting several hours could be
stored, then, if I remember correctly, this energy would supply
current US energy demand for 7 years.
But talking to you, that would seem to be a waste
I posted a link related to the thermodynamics issue. I have taken
thermodynamics courses in college. I will read whatever you post on

There was nothing accidental about Tesla's successful
demonstration of the magnifying transmitter. He was highly motivated
in working toward world peace and believed that an abundant supply
of energy would help toward that goal. The device at Shoreham, NY
was dismantled by court order; Tesla did not have a source of
Necessity is the mother of invention. Tesla invented radar but
the government, advised by Thomas Edison, rejected research into
radar until the onset of WWII when the MIT rad-lab began working
very hard building devices to enable us to win WWII.
What does this have to do with Missile Defense?
That's what I am trying to figure out and I will offer my
opinions later. Apparently, Tesla demonstrated that this huge source
of power can be used as a weapon.

Apparent to whom?

Based on a link I previously posted, Tesla believed that he
created a weapon responsible for the Tunguska event and sent a
letter to the government about the possible use of the weapon during

Not even Tesla had a perfect batting average.
Look, it is hard to hit targets even when you're aiming at them,
and trying hard, and there are ususlly an unthinkably large number
of inconvenient details that have to be tended to to make anything
Blow up a huge forest on the other side of the world BY ACCIDENT
The world isn't that easy. And because it isn't easy, VERY hard
jobs, like missile defense, may be, as a practical matter,
