I believe that the next step would be to design a heating element that also wicked. That way it would do away with extra material, it would be only one thing doing two jobs.
Sometimes, late at night, I start coming up with crazy ideas like, converting to A/C and using a micro induction coil to heat a metal wick. Eh, I don't even know what I'm talking about tho. I just remember at one of my past jobs I was instructed "don't leave any parts in the De-Mag when you go to break or it will melt a hole right thru the table" one day I did leave a part in the magnetic field for about five minutes and when I grabbed it I burnt the oh my goodness out of mgt hand.
