So, A0 has an area of 1 m2 and it’s halved for each next one in the series, giving A85 a surface area of 1/(285) m2 = 2.585×10-26 m2 = 0.02585 pm2.
The smallest atom is the hydrogen atom with a Van der Waals radius of 120 pm which gives it a surface area of 4×π×1202 pm2 = 180956 pm2 or just over 7 million times larger than the A85.
This seems to imply that you just replace all fossil fuel energy sources with batteries which does not even make sense. Once the batteries have been discharged, how would you recharge them?
What should actually be done is scale up renewable power generation and then you’d use the batteries to balance out the difference between production and consumption, which takes a lot less batteries than trying to replace energy generation with energy storage (which, again, would not even work).
Pumped hydro isn’t feasible everywhere, nor is geothermal
That’s the whole point of diversifying, use the sources that are available in the places where they are available.
Biofuel burning emits greenhouse gases
The point is that the greenhouse gases that they emit have already been captured from the atmosphere, which makes them carbon neutral.
Sodium ion batteries are a new technology and we don’t know how well it scales
It uses a lot of the same type of production as lithium ion, it is already being produced by some of the largest battery manufacturers on the planet, and being sold on the market, and we have years of research to give us a good idea of how it will evolve.
And the others aren’t proven technologies, so they may not be around for decades
Neither will fission plants. Even if we decided to start building out today, there are years before we actually see construction start, not to mention commissioning and eventually power production. We’re probably talking about the 2040s at that point.
No, the point is that the anti-nuclear crowd is trying to make it seem like there is no role for nuclear energy in the future alongside renewable energy
Some people, sure. But the person above wasn’t talking about completely removing all fission, just that we should have started building nuclear plants twenty years ago because it’s slow and comes with a massive up-front cost, and at this point we have other alternatives that are cheaper and faster to install. Nuclear fission plants are also a very centralized source of energy, so if there are issues in the future as a result of climate change (similar to what they’ve been experiencing in France) then you lose a lot of grid capacity all at once while trying to resolve it.
I think nuclear is a reliable source of power, I’ve been an advocate for it, but I don’t believe it’s the right solution at this point in time.
There’s pumped hydro, geothermal energy, and biofuel, in the future we’ll likely see some wave power as well. The point isn’t to have one technology for the entire grid but to have a diverse and distributed energy system.
For storage there are also many more options than just lithium ion batteries. We have sodium ion if you just want to swap battery for battery, but then there are also for example iron-air batteries that are projected to be dirt cheap, redox flow batteries, pressurized air, cryogenic energy, sand batteries for storing heat, hydrogen electrolysis, etc.
Not only will this make this a power grid that is less dependent on supply chains that are impacted by geopolitical conflicts, but it will also make it more resilient as the weather continues becoming more extreme.
I’m not in the list either, this is bullshit.
They’re from somewhere around the year 41900
I kind of foresee this ending with rooms getting spammed with posts that break the rules since the people doing it don’t have any sort of barrier of reentry.
I understand the intention but it’s important to be realistic about what the actual outcomes are. Is there anything stopping extremists from basically just flooding all rooms with hate?
In theory, as long as there is nothing ferromagnetic inside what you put into the center of the coil, there shouldn’t be anything happening at all, harmful or otherwise.
That being said, please don’t stick bodyparts inside workshop tools.
