   I'm sure there are substantial discussions of the question, but isn't
the freeing of hydrogen without producing "green-house" gases a problem?
I don't know if "environmentalists" are up to making a choice between
the destructive aspects of hydroelectric development and of thermal
electric power production.  Likewise, I am not sure of the aggregate
effects on the atmosphere of nuclear power production (it sure need
not contaminate the atmosphere with radioactive materials, but
boy, what to do with the fission products?).
   I agree with the generality that we are not doing enough to protect
the environment, but I am not at all sure that some simple trick
like hydrogen propelled aircract can give us a net gain.
