Waste from nuclear weapons is not the same as waste from commercial nuclear power plants.

Cars are also not safe, especially at 200+ km/h but somehow it’s OK to drive them this fast in Germany.

Edit: What I want to say is that there is no absolute safety.

You basically need a few conditions to be met to make this useable: tide needs to be high enough, there needs to be suitable geological formation that enables building of such power plants, it has to be publicly acceptable to build there, and you need to connect it to the grid. The last two can especially cancel eachother out.

However, this assumes you use potential energy. What you are envisioning might be more like current power (so kinetic energy) where I’m not sure what the limitations are. Perhaps it’s not too practical to build huge plants underwater in locations with relatively constant current and connect them to the grid

You are technically wrong, the worst kind of wrong :)

DT and DD fusion reactions release energy. More energy than is put in. It’s the whole system that hasn’t been energy positive. We’re close to breakeven in terms of plasma (heating power vs fusion power, and it’s not like heating power is lost from the system it still heats the reactor) but to be useful fusion power needs to be >10x heating power so the whole system is more than self-sufficient.

With energy positive here I mean useful energy positive, so electricity or high temperature heat.

Why are you comparing fossil fuels and nuclear “per tonne” that makes no sense. You replace tens of tones of nuclear fuel per year any you burn millions of tones in a comparable fosil fuel plant.

And regarding the carbon emissions from enrichment… Just use nuclear to power your enrichment plants. This way your emissions are extremely low because you don’t need much fuel and you use nuclear energy to produce nuclear fuel. French example: …m.wikipedia.org/…/Tricastin_Nuclear_Power_Plant

Hehe, I walked right into this one. You’re right. I totally failed at trying to be a smartass.

There’s also survivorship bias. All the crapily designed cars from 30-50 years ago are long scraped while some of the well designed ones are still around. With “current” cars you see the whole spectrum.

Two things to consider:

1. Humans need to eat. The land needed for agriculture already covers significant percentage of the habitable land. About half based on our world in data [1]. Yes most of this is due to livestock so this can be significantly reduced but still.
2. Other species also need space to live. Even if you look at it in s strictly selfish fashion and disregard the right of other species to exist - we are part of the ecosystem so if it dies we die.
