only antimatter could provide more energy density, it’s insanely powerful.
Nuclear energy indeed has very high energy per mass of fuel. But so what? Solar and wind power doesn’t even use fuel. So the energy density thing is a bit of a distraction.
just compare 1 ton of fissile fuel and 1 ton of Silicon or steel. how much power do you get out of it ?
What are you trying to say here? Are we still talking about fuel types here?
Again, let me point out that solar power does not consume any fuel. The materials used to construct the solar panels are not having any power extracted from them. And secondly, nuclear power plants require construction materials too. … So I really don’t know what kind of comparison you are asking for here.
yes it does, but indirectly : making solar panels comes with the cost of dumping them after they’ve been used, because they’re not fully recyclable. (which comes after 15/20 years if not earlier). plus they use vast amounts of land when much power is needed.
so yeah, energy density is relevant when comparing technologies. otherwise, why aren’t we all cycling to power our toasters / ovens / refrigerators ? because the energy yield is bad.
so no, you shouldn’t dismiss nuclear, because it’s insanity powerful for its cost.
solar and wind are great, but insufficient on their own.
Who cares? We use economics to sort out the relative value of radically different power sources, not cherry-picked criteria. Fission boosters can say that nuclear has a small footprint. Solar boosters can say that solar has no moving parts and is thus more mechanically reliable. Fission boosters can say fission gets more power from the same mass. Solar boosters can point to the mass of the entire fission plant, including the giant concrete dome that needs to be strong enough to survive a jumbo jet flying into it.
In the end, none of this shit matters. We have a way of sorting out these complex multi-variable problems. Both fission and solar have their own relatives strengths and weaknesses that their proponents can cherry pick. But ultimately, all that matters in choosing what to deploy is cost.
And today, in the real world, in the year 2024, if you want to get low-carbon power on the grid, the most cost-effective way, by far, is solar. And you can add batteries as needed for intermittency, and you’re still way ahead of nuclear cost-wise. And as our use of solar continues to climb, we can deploy seasonal storage, which we have many, many options to deploy.
The ultimate problem fission has is that it just can’t survive in a capitalist economy. It can survive in planned economies like the Soviet Union or modern China, or it can run as a state-backed enterprise like modern Russia. But it simply isn’t cost effective enough for fission companies to be able to survive on their own in a capitalist economy.
And frankly, if we’re going to have the government subsidize things, I would much rather the money be spent on healthcare, housing, or education. A lot of fission boosters like fission simply because they think the tech is cool, not necessarily because it actually makes economic sense. I say that if fission boosters want to fund their hobby and subsidize fission plants, let them. But otherwise I am adamantly opposed to any form of subsidies for the fission industry.
