Knee Brace
Okay Bruce Wayne has no knee cartilage and has to use a cane to walk. Suddenly he uses this brace and he doesn't have any more issues. What the hell?
Iron Man Arc Reactor
I'm not a doctor or an engineering graduate, so I can't tell you for sure how stupid this is. Let's just use some common sense to see how stupid this thing really is. This reactor was built in a cave with materials provided by terrorists. The original idea was that it kept Tony Stark alive because of the damage he sustained from shrapnel. Tony Stark improves the idea so that it will power a full armored suit that shoots some type of blast laser. Also where the fuck did Tony Stark get all the material for that huge ass Iron Man suit when he was held captive by terrorists?
Bat Themed Throwing Stars
I'm no Physics major, but it seems to me that the more sides a throwing star has, means the more likely you will hit something rather than it bouncing off a target. I'm not versed in Ninjitsu like Bruce Wayne, so I really can't say what they use. I'm just assuming Ninjas prefer throwing stars with more sides.
Also what's the deal with having to buy some parts of his bat disguise in bulk and other parts he has to make? Making one of those bat throwing stars is going to take a long ass time. It must take at least 5 hours to make one of those bat throwing stars by hand.
Flying Aircraft Carrier
I don't work for a government contractor that produces jets or aircraft carriers, but I can tell you for sure this is an idiotic idea. Maybe someone is working on it somewhere, it will never be developed though. A space ship would probably be less expensive and a submarine are the most valued ship that would be a fraction of the price as this. As to why an aircraft carrier would want to fly, it really wouldn't make sense.
Super Soldiers
The first Hulk idea involving potion that turns you into an incredible Hulk really wasn't that far fetched. Okay, so you take something then you look like a green bodybuilder, which really isn't that believable. It just looks way more believable then the newer Hulk features.
The new Hulk is 20 feet tall and can jump miles on a single bound. It's just so far fetched, it is extremely unbelievable regardless of the science the movie came up with that explains how it works.
