 electric water heater.
 
 
 Is electricity the only thing in the universe which will
 produce heat?

 What about the energy expended in carrying it up the
 mountainside?
 
 
 .... The lower
 atmospheric pressure only means they are able to boil water
 usling fewer BTUs because the boiling point temp is lowered.
 
 
 Hmm... and heat is energy... so therefor, if a propellor
 adds energy to the water, and by doing so lowers the
 pressure enough that the boiling point temp is lowered....
 
 A DUCK!!
 
 
 
 
 
 
 They cannot! The definition of the verb "to boil" precludes it.
 
 
 Read it again! You're missing something, just like you
 missed something in the two earlier examples I gave.
 
 BTW I can think of a simple test to prove you are or are not
 the CraptonŽ. Explain, in your own words, the term 'hull speed.'
