8. Iron Man Suit

- Company: Marvel Comics
- Real Science: Engineering, Mechanical Science
- Possible to Recreate: Somewhat
The Iron Man suit invented by Tony Stark in the comics has been theoretically possible for years. The only real drawback is the mini-ark reactor he has in the suit. Essentially, that little reactor is enough to power 3 nuclear power plants on its own. Therefore, having that much power in one suit is hard to replicate without something similar.

As for the overall suit itself. We likely would never make it out of Iron as it would be pretty flimsy if we did. Titanium is much better for this. This was partially done through the U.S. Armed Forces with the HULC Exoskeleton. Although in June of 2019, Mythbusters star Adam Savage built his own Iron Man suit and worked with a man that managed to fly it around.
