Japan has opened its first osmotic power plant

> While it is still an emerging technology being used only on a modest scale as yet, it does have an advantage over some other renewable energies in that it is available around the clock.

I notice the 'some' here, and the absence of the word 'nuclear' from the article, which of course is also available around the clock. Most readers will know something about Japan's troubled relationship with nuclear power and can fill in that context themselves, but to my eyes, it's a startling omission.

I love nuclear power and know a lot about operating them, however:

1) It's expensive. Very very expensive.

2) It's dangerous when not operated properly, and I don't trust commercial interests operating hundreds of these due to this reason.

3) It's bad for the environment, both the mining to get the uranium and all of the processes to turn it into fuel.

4) There is no answer for spent fuel.

Whereas with solar or wind you can basically remove #1, #2, and #4, however you still have to mine and process the materials.

Anyways, nuclear will be great for some niche uses, I am sure, but it isn't the answer to our green energy prayers.

We store it. There are radioactive waste storage sites in 39 US states, for example.

Humans haven’t stored anything for twenty thousand years yet.

Humans haven't had agriculture for twenty thousand years yet.

Also, this line of inquiry is still just tilting at windmills; "somehow, future Fred Flintstone manages to get a hold of equipment capable of digging out a mile of concrete and yet somehow not know what radiation is" is not a productive line of thinking at best and a bad-faith argument at worst.

Humanity's mechanical capacity to dig that deep actually post-dates its discovery of radioactivity, too. If they have the technology for it for them digging it up to become an issue, they'll be able to identify, trivially, that it is an issue.

I've never seen a tomato that could kill a man just from holding it in his hand.
