Don't forget that time when he held up a piece of glass, pointed to a house behind him with a glass roof, showed a presentation of power
output metrics and dualrability tests, and said they made solar roofs and just needed to figure out how to manufacture at scale
They had not, in fact, made a working prototype - they were still trying to figure it out. He stood up there with a piece of pretty glass (that was not in fact any type of solar panel) and entirely fabricated test results, and he lied over and over.
He must've gotten some artist's design model, produced several roofs worth, and made all of it up.
there are ways around them. convince them your product is "substantially equivalent" and they don't look too hard, apparently. (see - hard silicone penile implants)
I wouldn't say "effective". They're good at rejecting bad things, but they accomplish that largely by being very risk-averse. People who suffer because a treatment wasn't approved should count for more than they do. The best possible policy might be one that lets a few bad things through if it also lets through a lot more good things.
