Probably 95% of the dangerous uranium scare tactics are government sponsored fear tactics... fake news. The reason is to keep people from powering their cars and houses with a natural fuel (uranium), that could easily power them for almost free for 100 years. Such would shut down the need for oil (almost), and would change the whole political structure of the world.
Search on 'Galen Winsor' the nuclear chemist who ate uranium on stage to show how dangerous it is NOT.
Witness the nuclear fear scam. Scientist eats uranium. - https://www.youtube.com/watch?v=QmJN-LMPnX0
I think the reason is that they don’t want people making nuclear bombs in their garage. Bob Lazar showed how anyone could power their car with water if they were allowed to have access to the right materials (it’s on YouTube, search for it). We could all be powering everything with water, but I think it is a case of ‘this is why we can’t have nice things.’
Before talking about how one could power ones car with water you should take a look at something called "first law of thermodynamics" and "second law of thermodynamics", in order to use water as fuel one needs to invest more energy than it is generated during it's ignition.
Ironically, what BD says about filing cars with uranium makes more sense than powering cars with water and it would not break any law of physics, it would just elevate radioactive pollution within all urban centers in the United States.

Powering cars with water is something that the oil companies are hiding... so they can make money off the people.
The physics that they teach in schools is only a sliver of how things really work.
Wouldn't it be neat if a person could eat a little WM shrimp, and then blast off from his toilet like a rocket to the moon?
