Paul; Thanks for the info. I would have thought a mixture of diesel and H2O2 would have been the answer. No snorkel needed. Each injected into the cylinders separately.

V.80 gained its power from the decomposition of highly concentrated (95 percent) hydrogen peroxide, H2O2, known as Perhydrol. In essence, when the chemical breaks down, it releases superheated steam to drive a turbine along with oxygen to support conventional combustion for additional power or for crew respiration. V.80's designer optimized its hull shape for submerged operations, and the boat indeed demonstrated exceptional speed -- 28 knots submerged. It also demonstrated exceptionally high fuel consumption, 25 times that of a diesel engine, at exceptional cost. According to one source, one six-and-a-half-hour trial run consumed $200,000 worth of Perhydrol. The design showed great promise, but Hitler thought his war was won, so plans for production of a series of Walter boats were put on hold. Research continued, however, and perhaps eight, in several variations between 250 and 300 tons, were put into service in 1943-44. Not a nice chemical to be trapped in a big pipe with, but then notice that an early design of American nuclear sub used an alloy of sodium and potassium metals to transfere the heat from the reactor to the boilers. I wonder if anyone who designed these things was game enough to travel in them. Conventional deisel generator and battery subs had their problems too. Saltwater in contact with high current producing chlorine gas. Bad enough to be in a damaged leaking sub but chlorine as well. Regards, Paul Gobert. Yahoo!
