Comment on Cycloidal marine propellers: Efficient thrust in any directionparent

Comments

I have a response to what was the original top comment but now got displaced[0].

In short:

1) If you trivialize any technology nothing is new. Advances happen (mostly) by small steps, not leaps and bounds. According to the article it is more efficient. Seems like a win. Even if it isn't huge or crazy different. Is the lack of novelty because of: their tech? Our understanding of the tech? Something else? Who cares? If it is different it is different.

2) So what if it isn't (very) new? According to that wiki article that engine is made by one group. So even if its novelty is simply different enough to bypass a patent or in house knowledge, so what? More competition is good. What's the point here? We love monopolies? Only one company can make one type of thing? Type being at the abstract level, not detailed?

I'm not sure how either of these is helpful. Maybe you're saying something else, but it isn't clear to me.
