Publishing such an unusual work in such an unusual way, publishing these proposals, these two problems do exist since the very beginning.
The first problem is a spontaneous(?) reaction that "all things are perfect as they are; do not try to solve a problem that actually does not exist!".
However, all things are NOT perfect in the field of the wind turbines, of the turret-carrying vehicles, of the vessel azimuth thrusters, and so on.
Studying the long-time Evolution of Science, especially the Evolution of Engineering, we can find many cases where real revolutions began by ... "disputed proposals for problems that didn't actually ... exist"
Of course, we are not so conceited to believe that these proposals can touch off such a revolution.
The second problem is that doubts are likely to arise about the feasibility of these proposals; in other words, the mechanisms of these proposals is almost or just IMPOSSIBLE
Both these mechanisms, indeed, are unusual and strange but NOT IMPOSSIBLE.
There is a complete theoretical work, both in Mathematics and Physics, behind them, and fully operational prototypes for both mechanisms already do exist.
