For everybody claiming that locomotion without the impulse of a reaction mass is impossible: https://arxiv.org/abs/2112.09740v2 and before anybody only reads "spacetime curvature" and thinks the paper is talking about a warp drive, it is not. Anyway, this Genergo thingy seems to be nonsense IMO, or they would have actually explained how it works.

Here's the pre-print: https://arxiv.org/pdf/2112.09740.pdf I think their figures answer your questions...both theoretically and empirically. Figure 3 shows the difference between curved/linear vertical motion.

Edit: Here's the pre-print: https://arxiv.org/pdf/2112.09740.pdf I'm not sure others have read deeply into the article. While there's always some subtle ways friction can sneak its way, the authors account for the obvious. The article has a lot of definitions, which makes the crux difficult to pinpoint. They use the word "shape" many times to describe the configuration of the four motors. I think this adds confusion. Let me try to summarize as I understand it without using the word "shape." The authors are measuring the net position of the arm holding the two motor tracks. The arm can only…
