Project Orion

This guy wanted to detonate atomic bombs in the atmosphere for scientific purposes.
Project Orion presented a nuclear pulse engine which allows for quick acceleration. Unfortunately, some minor problems, such as the high-level risk, radiation and the huge amounts of pollution stood in the way and then the international agreement to ban nuclear explosions in the atmosphere from 1963 put the lid on the coffin of the project. Despite that, we have to say that this technology would probably be not all that much useless and irresponsible in space itself, which is why it’s so far behind in the ranking. Perhaps the opposite is true – nuclear pulse could move way larger objects than shuttles way faster than what is currently possible. And leaking radiation is space wouldn’t probably be such a big deal.
