- MichaelZuo 5y agoThanks! In scaling up the fragility of the material seems very likely to be a big factor, cube-square law and so on. I wonder if there’ll be physical testing of proposed designs, are there even near-vacuum wind tunnels?
- arhpreston 5y agoA lot of that talk compares theoretical results with experiments in a low-pressure wind tunnel (see e.g., the slide at this point https://cassyni.com/events/6GYLBKG5pBd4su8dm9A9FB?t=255.0s https://cassyni.com/events/6GYLBKG5pBd4su8dm9A9FB?t=255.0s for a reference). It's quite a simplistic (2d) setup however. I'm not aware of any more complex experiments.
