I've always found it slightly funny that nuclear power is technically just a fancy steam engine.

[-] [email protected] 121 points 7 months ago

Almost all power source that generate electricity are fancy steam engines.

[-] [email protected] 51 points 7 months ago

Wait, it's all steam engines?

Hydro, wind, solar, and wave/tide energy capture are not.

The crazy part is photovoltaics are the only power source that doesn't spin something to make electricity. Truly an outlier.

[-] [email protected] 13 points 7 months ago

solar

Except the ones that are. (Concentrated solar power)

Hydro is the most fancy steam engine since it waits for the water to recondense to make power.

Has anyone tried using cold steam yet?

It was a bad call to stop, but now it's an equally or worse call to start again.

Renewables win on essentially every measure and get better every day while nuclear gets worse every day.

[-] [email protected] 9 points 7 months ago* (last edited 7 months ago)

how is it getting worse? there are tons of modern fail-safes

[-] [email protected] 13 points 7 months ago

It's getting more expensive year over year, while renewables are plummeting in price.

[-] [email protected] 7 points 7 months ago

Nuclear gets more expensive. That's worse.

Conveniently leaves the "get the fissile material" and "store the used fissile material" steps out.

Run low on water, stop reaction. Fission products keep getting hot even though reaction stopped. Not enough water to cool them off. Shit.

[-] [email protected] 41 points 7 months ago

That’s why you have a closed water system and multiple failsaves.

Unless you want to cyka your last blyat.

[-] [email protected] 10 points 7 months ago

What do I need to roll to pass the failsaves?

thankfully modern ones like molten salt reactors have passive safety, where they stop the reaction if overheating occurs.
edit: My mistake, there's no active commercial molten salt reactors.
But nuclear power is very safe nowadays because of the multiple fail-safes, which some can still be passive like emergency cooling.
I much rather get electricity from magic rocks than destroying rain forest in developing countries drilling oil, gas or mining coal.
The biggest risk in nuclear is environmental disasters like in Fukushima's case, which is the last significant nuclear incident in past 13 years

[-] [email protected] 18 points 7 months ago

And are those modern molten salt reactors in the room with us now?

Ah yes, the passive safety of the molten salt spontaneously catching on fire when in contact with air and can't be put out with water.

Same applies to geothermal.

lava is really hot

use lava to boil water

use steam to turn a generator

free electricity!

Chat is this legit gameplay or an exploit?

[-] [email protected] 17 points 7 months ago

Trolls and exploiters at it again. If god intended for us to make nuclear energy then he would've made it appear in nature. Stupid scientists making stuff from gods creation.

[-] [email protected] 7 points 7 months ago

Is just trolling.

[-] [email protected] 29 points 7 months ago

I love these, there's no way that would ever work

[-] [email protected] 22 points 7 months ago* (last edited 7 months ago)

free

The only completed attempt in last 25 years in US (Vogtle), cost over $15/watt. Before fuel, operations, security, waste disposal plan, and no insurance.

Turnkey (containers full of batteries) systems in China are under $100/kwh. A possible imported cost of $100/kwh.

5gw of solar and 19gwh batteries would have higher capacity factor than nuclear, use same transmission infrastructure size, and cost $7/watt. Where winter production is not enough to fill batteries, the batteries can still be charged by wind or peaker plants that can run a bit more efficiently for a continuous time over a day instead of in bursts.

[-] [email protected] 22 points 7 months ago

TBF 90% of the cost of nuclear in the US is political resistance. Not engry meeting

i'm willing to have fizzle reactors on the moon. and mars. but i am not willing to shoot the fizzle materials via rockets to the moon or mars because of rockets tendency to blow up when designed and built by the humans.

i want no earth fizzle.
