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

Waste from nuclear weapons is not the same as waste from commercial nuclear power plants.
Unfortunately use of fossil fuels also continues to hit record numbers year after year.
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
Hehe, I walked right into this one. You’re right. I totally failed at trying to be a smartass.
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: https://en.m.wikipedia.org/wiki/Tricastin_Nuclear_Power_Plant
With energy positive here I mean useful energy positive, so electricity or high temperature heat.
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.
(Established) scientists have a long history of ignoring new theories not science itself. But that’s because at the end of the day scientists are still human.
Science is not great at working on a very short time scales. But give it enough time so more evidence is gathered and possibly some stubborn influential people (that can’t accept a new theory) die and generally we get closer and closer to truth.
It all depends on what is actually trying to be communicated. With your definition most meals would be plant based so why even bother to say it. With definition where plant based means no animal products it communicates that it is fine for vegans and it’s likely less offensive for people allergic to word “vegan”.

Language is interesting in this way. Same words in different contexts mean different things.
“Based on true events” = “Contains traces of what actually happened”
“Plant based” = “Does not contain animal products but can contain mushrooms even though they are not plants”
Homo sapiens also doesn’t originate from Europe.
How far back does it count? Humans originate from Africa so everything we do can be seen as Africans doing things with stuff from all over the planet. Or perhaps even that is not far enough. What’s the origin of the first mammal… The only contestant is change and life is good at mixing things up.
Two things to consider:
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.
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.
Mysterium - something easy to learn and can be played by up to 7 people. One of the players is trying to tell others (psychics) who their killer is using very nice looking but rather ambiguous cards.
Maximum apocalypse - up to 6 characters doing different missions in different types of the apocalypse (zombies, nuclear war, aliens, robots). Map is randomly generated so even though there is limited number of scenarios they are replayable.
Sherlock Holmes consulting detective (multiple boxes) or Bureau of investigation - investigation in Arkham & elsewhere. These are text based puzzles (e.g. solve a murder case).
Spirit island - it’s basically anti Settlers of Catan :) Still learning to play it but so far it seems like an amazing game with many scenarios…
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.
