Re: [TCML] Prepare a Hot Dog
Hi Jim, Adam,
Jim, I'm sure you are correct about the energy
vs. mass/specific heat issue of completely
"vaporizing" an average sized tomato, as you
have already eloquently "ran the numbers" for
us. However, I would also propose that although
the inards of the tomato would not be totally vaporized,
I do believe that the sheer percussive kinetic force
of a 10 kJ discharge that was properly directed
into the central mass of the tomato would indeed
"blow it apart" even if the resultant temperature
of the remaining tomato pieces was not signifi-
cantly above ambient. Of course, this is also
assuming that the 10 kJ is discharged into or
inside the tomato through a low enough impedance
path to allow for a rapid enough discharge time. I think
Peter Terren has video of this being done on his
website tesladownunder.com. and I'm sure you
could also find some interesting vids of similar
experiments on Youtube.

10kJ isn't even close to enough to vaporize a 100-200g tomato. It will
barely even get it to boiling.
10 kJ does a nice job vaporizing a meter of thin copper wire, but
there's not much mass there.
