Sound- absorption or reflection

[timvasqz]

To disipate heat, is to transfer it. Steve maybe you can disapate it
thru a dupree valve back to the tank? Call it Hot$$$$ ?

I understand that the vault gets up to +250 degrees(USA). I guess
that is a factor for Ernie to consider once he removed the disipation
path of the vault heat to the bus interior. where does that heat
now go.

Insulation keeps environments from disapating heat. heat is removed
so the method to remove the heat in the compartment would now be the
radiator system and the diesel engine is the heat sink, but the
diesel engine caused most of the heat. If the origional design was
not intended to do that it would have to be beefed up

If you insulate the exhaust the otherwise exposed metal does not
radiate heat in the compartment. heat goes out the stack with the
exhast air. But is the stack able to take all the extra heat.

If someone complains to me about the noise my genset is making I
say "What? can't hear you, my genset is too loud".
