Some of the commenters on the linked website claim it violates physics principles. Like many people here I took several university physics courses and it seemed plausible to me, but I don't have confidence in what seems plausible to me actually working. There are a lot of "oops, I didn't think about that" types of things when making calculations in physics, from my memory...
Note: After reading post by nickparker here, note that most of the commenters on the linked website who were claiming mistakes with the math seem to be wrong. Nickparker here posted links to what seem to be valid calculations showing the math works out.
- andbberger 8y agoFor sure could be subtle crippling problems. But it passes the sniff test with flying colors
- ss2003 8y agoIt's very good example of why we need real space testing of propulsion concepts. Once we have a bunch of engineers actually living in interplanetary space, where they can do easy experimentation, we will see some rapid developments.
- mnl 8y agoNot really, actually we understand pretty well electromagnetism, electrodynamics, plasma physics and numerical methods for those. We can simulate these things, so there's no need to reinvent the wheel going full Faraday at the 21st century. A few trained physicists on Earth would do, yet people get so excited wilfully ignoring all this.
