I wasn't talking about everybody who read it. I was talking about the formal or informal members of the objectivist cult.
I'm curious what you mean by "informal" or even "formal", since there really is no such thing as either, unless you mean those who actually write or speak for the Ayn Rand Institute, or people who write or speak for some other explicitly (or at least putatively) "Objectivist" group. There are a lot of people who consider themselves "objectivists" (just as someone might consider himself "Marxist" or "Marxian" or "Trotskyist" or "Kantian" or "socialist" or whatever) who just don't fit your description.
The point of the criticism is that crediting Galt with the invention of such a revolutionary motor is another piece in the story that makes Galt the most moral AND most determined AND most intelligent AND most industrious AND most strong-willed AND smartest (etc. etc. etc.) person who ever lived. He completely lacks all crediblity as a character. Even if such an engine was in fact possible in real life, it wouldn't matter for this huge flaw in the novel.
Galt was not characterized at the smartest person who ever lived -- nor as the most moral, nor any of the other things you describe. At least by my recollection, Rand made no comparison of Galt to people in times other than the "present" of the novel. (I guess I'm accusing you of hyperbole.)
What you call a "flaw" was Rand's stated intent, that Galt (among others) should be a "romantic" (not the pulp-fiction sense) hero -- an image of mankind as we should aspire to be. She wasn't writing a "realist" novel, and she hated them and the antiheroes that usually show up in them. You may still think it a flaw, but it was her explicit intent and is the main reason the book is and has been so popular: Because people want to look up, not down or horizontally.
Nietzsche IS awfully misrepresented by his idiot followers, but Rand has none of the depth or intelligence or Nietzsche. It's not even close. Nietzsche was a great intellect, Rand, mediocre.
She has one "great idea" (egoism as the source of virtue and morality) which has the rather obvious problem of being utterly false. Plato already highlighted, 2400 years before Rand, the problem with Rand's argument: if egoism is one's guiding light, then the best course is to pretend to be honest and brave for "outward consumption", and to actually be a dishonest, cheating bastard.
Rand was quite familiar with Plato, and detested nearly everything about him. (So do I.) The argument must implicitly assume that the dishonest, cheating bastard might successfully fool all the people all of the time, which is (gently, now) not bloody likely. In other words, your "egoist" is either a damnfool or insane.
Rational self-interest would prohibit any such attempt because it will obviously fail.
Did it occur to you that the reason objectivists are unbearable is precisely because they think they have access to a holy text by the one true prophet that "figured it all out", and they feel immensely superior to the poor, blind 40-year-olds who haven't?
Again with that premise, which I doubt based on personal experience. As a 13-year-old, yes, I would have been one seriously unbearable jerk because I was too immature to have have "a center" (or social grace, for that matter). That's why 13-year-olds can't vote or drink or choose to have sexual relationships. I have no doubt that there are adults who have the same shortcoming, but as I said, you have a problem with your data.
Replace The Fountainhead in the quote above with The Bible and see how it sounds. Like a Christian Fundamentalist preaching?
That's your best strawman of the day! I said it could have saved me time trying to figure some things out for myself. How does that suggest that I wish it wasn't (or weren't!) my responsibility to think for myself? (Which is what the Bible does for people -- unless I, too, am guilty of a strawman.) [Merde], by that standard, I probably shouldn't read Plato, either, because I wouldn't want to let someone else put an idea in my head!
(But I'll go ahead, because I think I can handle it.
