Hey, I have an idea: How about we retro-fit the 8 biggest container freight ships on earth with nuclear engines like submarines, air carriers etc. have, or even electric ones.

That would cut the air pollution by something akin to the pollution by most of the cars on the planet, combined. Those things run on the worst sludge fossil fuel in existance.

So why are we not doing that?

I wonder because cows do not fart, they burp. And methane breaks down into water within 14 days of UV exposure in the atmosphere, and I like cows.

Another idea is Thorium reactors, they can run on spent fuel from traditional nuclear plants which is mostly _not used up_ and therefor must be stored millions of years. This would reduce storage time to thousands of years, make the spent rods a commodity and the physics preclude catastrophic meltdowns, make it really hard to enrich whatever those thingies they make thermonuclear atomic weapons with.

.. why are we not doing that either?
