Do they actually work? I don’t have actual experience, but I heard that they are only used by people who might benefit from them and thus the authors are automatically suspicious to the reviewer, plus you almost always cite your previous papers in a pretty obvious way, so it’s hardly blind anyway.
I didn’t check the calculation, but I guess it assumes perfect conversion of motion to heat. But it’s good to know that if you can get a perfectly static chicken, you can hypersonic-slap it cooked.
