RE: [TCML] Prepare a Hot Dog

["andrew" <andrew@xxxxxxxxxxxxxxxxxxxxx>]

Exploding tomatoes and hotdogs. 
Interestng stuff and highly enlightening to the greater scientific
community!
Nothing wrong with a ccoking lesson here I guess!

Keep up the fun.

Thanks
Andrew

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.

measure the current 120 volts pulls.

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.
