There's a lot of cringey comments and statements in that video that are just hilariously wrong I thought it might be satire at first. Apparently you can't put steel in contact with concrete because a tiny whiff of surface corrosion is going to seriously risk the integrity of that 3/4" thick steel pipe... Not to mention claiming that clearly they didn't account for linear expansion of the pipe right after poking at the linear bearing material and saying it looks like they put it on some type of plywood.
That video is 20 minutes of him spouting off the same kind of nonsense and trivial mistakes that he spends every other video deriding other people for making. He even makes some mistakes that are basically just pure physics, which he of all people should know is suspicious on the face of it. He claimed that if a test vehicle failed to slow down and impacted the far end that it would rupture the test track. It's a 3/4" steel pipe with a massive thick door and the inside being at a weak vacuum, it's not coming off. Not to mention his differential heating claims which would not change with length given that the test track can obviously resist the bending with just the weight of the tube elastically deforming it to keep it straight.
His own zealotry on some subjects blinds him to his own obvious mistakes. If it was someone else making a video with so many errors he would be all over debunking it.
