Re-posting Bob Power's email. It seems his expertise has narrowed out some
solutions: Please take a look!

 Hi Pow,

1.  Heating - OUT.  requires too many BTUs/hour per square foot of surface.
2.  Pressure based - probably your best chance.  Most communities use a
bubbler system to keep water open. Coe Lake in Berea is a good example  You
could get operating costs from the City of Berea, I would think.  Lake
Isaac in Strongsville is another.  Pumping water from the Cuyahoga around
the Cold Coast Guard station is a possibility, and you could use a wind
turbine to do that.
3.  Chemicals??  No, the EPA would not let you pollute the waters of Lake
Erie, even if you think the chemicals are "safe".  There have been some
experiments with melting ice using black pigments to absorb solar energy
that you might want to investigate.  But what black pigments are "safe"?
4.  Nanotechnology - not in my lifetime, and you'll still need a permit
when it's closer to reality.
5.  Motor-Propeller combinations - a subset of alternate 2, somewhat
viable; could be connected to a wind turbine.  Permitting issues since the
system would be submerged.
6.  Shelter with IR heating - doable but you still need a power source.
And would the birds go to it?  So unnatural...Birds need to see predators
coming from a long way off.
7. Breaking down the ice manually - at first I thought this might be a
decent idea, but if the lake is frozen over, where do you put the ice
you've cut up?  Just pushing it into an area with open water won't gain you
anything.  You'd have to put it on shore or start stacking it on top of
existing ice.
