re: 'Speed Bump'
I have been under the impression that if a body of water is heated and open to the air it will evaporate at a faster rate, then if the water evaporates it will become colder.
Large bodies of water such as the oceans should take some time to heat up and then cool down.
Seems to me that the laws of physics still work after all.
Of course if the thermal energy escapes from the system, then what?
