Now for the big question. Do you put a coil of heater wire in the liquid, or will two large chambers (vertical, > 10 centimeter diameter) separated by a 0.25cm thick insulating plate-membrane with a 2 square centimeter area (~ 5/8 inch diameter hole) in it form bubbles in the constricted area using saltwater or LiOH, K2CO3, or such with a 70 ohm-cm electrolyte (about 9 ohms resistance) and voltage applied between the two conductive chambers?
At 120 volts that comes out to over a kilowatt dumped into the constricted zone. Ness Engineering's "liquid resistors" data sheets give information on the electrolyte strength for various salt solutions. * **http://home.san.rr.com/nessengr/* <http://home.san.rr.com/nessengr/> On Dec 26, 2007 3:58 AM, Frederick Sparber <[EMAIL PROTECTED]> wrote: > When clear Pyrex glass coffee pots came out after WWII it was quite a show > watching > the bubbles form when the pot was in direct contact with the hot-plate > heater coils. > > *http://wins.engr.wisc.edu/teaching/mpfBook/node27.html*<http://wins.engr.wisc.edu/teaching/mpfBook/node27.html> > > "Vapor may form from a liquid (a) at a vapor-liquid interface away from > surfaces, (b) in the bulk of the liquid due to density fluctuations, or (c) > at a solid surface with pre-existing vapor or gas pockets.
