 Silly ideas for incubators

Well, these are just some silly ideas...
one, put salt water in with the heater, becuase salt water conducts better than just water, so the water will heat up faster, be defused faster, and cool down faster, so as to keep the heater working more often and putting more heat into the area.
two, making boats out of aluminum foil to float on the top of the water, thereby acting as a better medium (readily heated up, readily cooled down) to act as a transfer from the warm water, to the air... (aluminum diffuses heat quickly)
Well those are the ideas that i've been thinking about. Basically trying to get the heat from the heater to the air faster than just plain water. What do you guys think?

Take your fishtank heater, and put it in the open air. You'll find that the fish tank heater get very hot, but the air around it doesn't get hot. This is becuase glass to air have a very bad rate of energy transfer. However, if you put the heater in water you'll find that the water around the heater warms up, but the glass on the heater doesn't heat up as significantly before. This is becuase Glass to water transfers energy better.
my question is, would adding salt to the water make it transfer energy better (becuase salt water is a better conductor) thus heating up faster.
the aluminum boats floating on the top of the water idea came from an idea for a better water to air transferr of energy. (ever notice how you can take a peice of aluminum foil out of the oven, and within seconds it's cool enough to touch?) Well, aluminum likes to get rid of energy, so i thought this would be good becuase it would take the heated water to the air much faster.
Please if these ideas don't work, tell me.

Salt has a thermal conductivity greater than water. ok.
BUT: If you really think the heat thransfer to water is a problem, then use something to move the water. This way the heat transfer coefficient will be much(MUCH) higher than by conductivity alone.
Aluminium: Yes, it has a good thermal conductivity. BUT: if you place it on water, it doesn?t help at all, since the limiting thermal resistance is the water, and not the aluminium. This means that aluminium will only be able to give off as much energy as water will be able to deliver.

That's some pretty good ideas, makes me think of my other hobbie, overclocking .... hey wait ! I'm having ideas.
Peace,

get a good book on thermal dynamics. should clear up everything.
sorry.. i know its a bit of a dick answer.. but it is the honest truth..
I'll do my best in lieu however:
salt: BAD, highly corrosive.. pure deionized or distilled water is the best for this.
aluminum foil? not much help.. perhaps as a heat spreader, but otherwise I don't see how. a double boiler type design like what anno posted is probably the easiest you can do without a machine shop at your disposal..
good luck
