(This concept has been evolving in my head for quite a long
Ever since I found out about railguns, I've been pondering
[Madcat]s Laser Railgun (linky 1) is a neat idea.
So my crazy brain started smashing things together. If we want
to fire a pulse (or stream)
of plasma, we need to create
conditions that plasma likes. I remembered (from my distant
past) seeing a graph of the breakdown voltage (linky 2) & how it
has a minimum at a low pressure.
So I thought, could a soundwave be used to prouce that lower
pressure, but intermittently? But speakers lose pressure quickly
with distance (1/r² I think).
Then I found out about directional speakers (linky 3).
So that gives me a highly directional stream of low-pressure air
pockets, with the added convenience of high pressure pulses to
push things along.
But plasma, being hot, wants to cool down & dissipate. So fire a
high-powered laser into the plasma, to keep it happy.
So, we have a directional speaker, with a taser to create plasma
discharge a small distance in front (to be in a more "stable"
wave, rather than close to the speaker where the waves are
interfering), & a laser aimed through the centre of the speaker
to (hopefully) be asborbed by the plasma to keep it hot.
I have no idea about what frequency would work best (most
LRADs use ultrasonic freq's), whether it would be badly affected
by wind (probably...), what type & frequency of laser to use;
but if it works... shocking!
