Will the submarine eventually put the super-Dreadnought out of business? This question is a live topic just now for two reasons. The first is the decision of Congress to build much larger undersea fighters. The second is the success of the Benton in setting a new record for staying under water at Long Beach, Cal....The submarine Benton is a new type invented by John M. Cage...

I get the impression that the main reason that Cage/Neff system failed was one of scalability.
This link will take you to a copy of Friedman's U.S. Submarines Through 1945. On page 119 at the bottom of the left hand column is a reference to the size of the Neff boat. A 150 ton boat would be approximately the size of a B-class. This is a very small boat even for 1916. Friedman states pretty firmly that this was to be SS-108. Also check out page 76. There is further info on Neff system tests conducted on N-2. Friedman mentions in a footnote in his book that the Navy offered a K-class boat for trials, but this was enventually turned down due to concerns about availability of boats for war duties.
On a small boat with relatively low powered gasoline or diesel engines the idea of supplying air to the engines from compressed air banks might work. But as the engines got more and more powerful, it quickly became apparent that it was impossible to store enough air to run the engines for any length of time. For the same reason, the idea of dealing with the exhaust by condensing, compressing, then pumping it over the side lost practicality as you scaled up the engines. Handling the toxic exhaust gasses without leaks in the sealed hull of a submarine must have been a real issue as well. Can you imagine how much compressed air would be needed to run just one of the big GM-Winton V-16's or the Fairbanks Morse 9 cylinder rock crushers of the fleet boats, let alone four?
I am not completely immersed in the scientific principal, but I believe there was an issue with the amount of energy inherent in compressed air versus an electrical storage battery. True, while air banks a quite a bit lighter than batteries, for the amount of space taken up (about the same for air banks or batteries), batteries were a lot more efficient and provided more energy and therefore more horsepower. Friedman states that "Neff eventually proposed to use the diesels only for high speed; at lower speeds, the boat would run on compressed air. High-speed underwater endurance would far exceed that offered by conventional batteries because the fuel contributed so much energy. Compressed air could not store as much energy as chemicals in a battery, however, at 5 kt Neff managed only half the endurance of an S-boat."
The Cage/Neff system gained some favor early on due to the rather primitive state and unreliability of electrical systems and storage batteries at the time. The batteries were fairly low powered and heavy and were very gassy when being charged. The battery acid was also a major hazard, as evidenced by the F-4 disaster. There was a strong desire to get around these limitations, thus the interest in Neff's system. Unfortunately, at about the same time Neff was pushing his system, there were rapid advances being made in electrical technology development. These advances made the scalability problem even more acute and they quickly made the Neff system appear to be dangerous and problematic. Batteries simply had far more potential for development. It is ironic that a system intended to make submarines safer and simpler was so quickly overcome by other technological developments that it came to be seen as dangerous and problematic itself.
Neff was making a very early attempt at a closed-loop propulsion system that would allow high submerged speeds and endurance as well as increase safety. Unfortunately the technology of the time wouldn't support it and science was against it. It would take later developments of the Walter hydrogen peroxide principal and the rise of nuclear power before this dream could be realized.
Note: The following patent was granted to Neff in 1932 for a much larger submarine. This document is what lead me to believe that Neff did not immediately give up after he was rejected by the General Board in 1922. There are no dimensions listed for this boat, but it appears to be approximately H or K-class in size.
