Tesla "Death Ray" not really a ray?

    Hello all,
    I recently finished a biogrpahy of Nikola Tesla by Mary Cheney
    (Tesla: Man Out of Time). It's chronological and has some references
    to his inventions and hypotheses but in minute detail.
    The description of the "Death Ray" got me thinking. There is a quote
    about stopping 10,000 enemy planes from entering within hundreds of
    miles of a city's borders.
    Since his research was heavily into fields, maybe it wasn't a death
    ray afterall but instead a force field? Whether it repelled or had so
    much energy it disintegrated things on contact who knows, but such a
    device could fall under the same description. It would be like a field
    shell instead of a filled field sphere.
    Thoughts on this line of thinking? In short: Taking an electric
    field and allowing it to be repulsive or filled at it's outermost edges
    with highly-charged particles and/or an atoms thickness?
  2. Hi,
    It was just such a thought in the 1930's, when the powers-that-be
    realised the UK's vulnerability to the heavy bomber, that made them
    request of the scientific community a means to achieve this. A few back
    of the envelope calculations however, showed that this was impractical
    but it did act to accelerate the development of early warning radar.

    The inability to generate very high radiative powers, the formula for
    the surface area of a sphere and latterly, the radar equation showed why.

    Cheers - Joe
