- I am sure there is no need to tell you, Richard, that there is more to Physics
- than the conservation of energy.... As you know, there are laws of thermo-
- dynamics, laws of plasma physics, and one or two other 'laws' that explain our
- physical surroundings. If I took a megajoules worth of Gasoline vapor and the
- perfect amount of air and compressed it into a mythical light alloy housing
- and then applied an erg or two of electrical discharge, we both agree that it
- would be terribly unhealthy to stand nearby. And I doubt that we would argue
- over the difficulty of finding all of the pieces of the housing... These laws
- of thermodynamics we are both familiar with. Now let us take this same housing
- and pass two large electrodes into it. One through each bearing sleeve. I mean
- two inch in diameter, fully intergrated into the housing, Humongous electrodes.
- Then let us place about a kilogram of graphite directly between them. Now let
- us discharge, as quickly as power source resistance will let us, a megajoule of
- energy through the graphite. This is where we will part in our agreement. My
- thoughts are that a person standing next to the housing would here a very (very
- ,
- very) loud bang. If they turned to look at the housing, they would see it
- turning bright red. And if the housing temperature exceeded the plasticity
- limits of its material, they might even see the housing begin to collapse as
- the vapor pressures of carbon and the light alloys quickly fell to nothing...
- Same energies vastly different results... All within the bounds of some 'law'
- of physics here or there...
- Again, I am sure we might disagree somewhere....
