  • or the earth being 10,000 years old?

    Humanity, or at least written scripture, is roughly 10,000 years old. So if you take humanity = earth, then yes it’s approximately true. But also, it’s an incredibly egoistic viewpoint because earth is not just humanity.

    Edit: by humanity, I mean human culture and not so much human biology.



  • fair argument

    I want to add something to it:

    First of all, a lot of that uranium seems to have been there and slowly decaying for a long time. I think, what we humans did was to “wake it up” and turn it into some more violently-reacting other elements, for the sake that we get the energy out of it at an acceptable pace. Now, though, it’s severely more dangerous than it was before.

    Also, I’ve an idea about what to do with the waste: Since the waste tends to activate itself due to neutron activation, put a lot of it (but just barely not enough to make a bomb) together and it will activate itself to react violently at very high speeds, but just barely not fast enough to explode (make a bomb). That way, you can get a lot of heat out of it rather quickly, and are left with burned-out material (which contains less radioactive potential).




  • We’ve had this discussion here on lemmy a few days ago: practically all electricity generation is by making turbines spin.

    Hydropower means river makes turbine spin. Wind power means wind makes turbine spin. Coal/gas power means combustion makes turbine spin. Nuclear means hot steam makes turbine spin.

    However, that doesn’t mean that all electricity sources are spinny things.

    • solar cells have no mechanically moving parts
    • batteries utilize chemical energy directly
