That's cool! I've done many of those experiments. In fact, I built a HERF
gun (a sort of microwave ray gun) out of microwave oven parts, some scrap
metal and duct tape. It worked really well. I could fire a beam of
microwaves that could fry a remote control, make a CD go up in sparks and
light a flourescent light bulb from 7 feet away without wires. Just for the
hell of it I put my hand in the beam and it felt warm but suddenly I felt a
burning pain on the side of my middle finger where a large blood vessel runs
and pulled my hand out of the beam. I won't do that again. :-S

I noticed when filming it that everytime I placed something metal into the
beam, the camera would go fuzzy from the backscattered microwaves. This is
what gave me the idea of sending a microwave beam into the ground and
checking for backscattering to find meteorites. If you were to use a short
wavelength and send it down by means of a bunch of waveguides all lying
parrallel to eachother in a big grid and pointing downwards, you'd have a
wide but strait beam and the whole apparatus could be put on wheels and
pulled behind a vehicle. If each waveguide had a detector in it to detect
the backscattering then you could figure out how big the object was by the
number of waveguides that detect backscattering.

I just got my letter of acceptance from the college I applied to and it's
for an electronics engineering course so maybe when I'm done it I can build
this bad boy!!

Cheers all
Graham
