Nuclear lighthouses built by the Soviets in the Arctic [video]
Someone who is a nuclear expert, could you answer some of my nuclear questions please.<p>1) the sun is a giant nuclear reactor and we indirectly derive most of our energy from it. Radioactive elements in general are the most energy dense and I agree with the idea of “nuclear energy in every home and office”. Sounds amazing. What makes nuclear so dangerous?<p>2) are there nuclear materials with short half life. Such that if you turn it off, it’s safe by default. It doesn’t require constant cooking and isolation.<p>3) is if there is a super intelligent alien species out there, most likely they’ve figured out how to harness nuclear power and make it portable. Is there a way we, as human species can do the same?<p>If voyager and the Mars rovers are operating on nuclear power, can we have nuclear powered planes, cars and robots that are safe and ubiquitous?
