RE: The Model

[Schmidt Mickey Civ 50 ES/CC]

I have an idea for a small scale model. I am not real knowledgable about aquarium fish, but I do know there is a small glass encased electric heater for the tanks. Anyone want to do the actual construction and test?   Test 1: I do not know the true physical size but for test purposes suppose we place such a heater in an aluminum (or stainless steel) tube filled with a working fluid to cunduct the heat from the heater to the aluminum skin. The unit would be sealed and weighted to make it sink.  For the purposes of this initial test the power supplied to the heating coil could still be from an electrical outlet. But a solution for a self contained power source to provide heat for the model still needs to be determined.    Test 2: The working fluid would be water from the melting ice.  Holes in each end of the tube the meltwater would flow through the model allowing the model to test the idea of using water from the ice itself.   Test 3: A  model with a small pump inside. The pump would collect warm water and pump it out of  the model to impart rotation and maybe to jet water toward the front of the model to more rapidly melt the ice.   Test 4: Build a self contained model. Power source and circulation pump, plumbing etc.   Does anyone know of very small pumps?   I will try to draw "napkin drawing #2" and forward it later..   Mickey D. Schmidt, Dir.
