Most new clean energy does not use boiling water.

Pushing electrons? Really? Man of your talents?

there is a power generation scheme that uses high temperature fuel cells. optimally it could run on hydrogen only, but because it runs hot, it is able to take almost any flammable gas, along with some steam, and it forms hydrogen internally, then oxidizes it. this alone generates bulk of electricity, but offgas is hot, so it goes to heat exchanger which boils water, which then turns steam turbine

That's just burning a hydrocarbon with extra steps.

[–] fullsquare@awful.systems 12 points 2 weeks ago

it replaces gas turbine with a fuel cell, which is a good couple % more efficient than CCGT. still under development. there is also another variant where hot offgas is generated under pressure and expanded directly. no steam, same effect

What is worst is that if we look deeper, we find out that everything is just turning the mill

The only advance would be solar that was capable of not using a mill that have to turn.... Everything else? Just a fucking mill

[–] Zorque@lemmy.world 35 points 2 weeks ago (5 children)

We rotate around the sun, though

[–] Tiempo@lemmy.dbzer0.com 25 points 2 weeks ago

Fucking damn it!

Looks like the Dutchies were right in the first place

[–] Gonzako@lemmy.world 12 points 2 weeks ago

Nah, the dutchies also invented the stock market.

Solar and batteries (chemical). If we could harness lightening then that's come without mechanical energy as well. There's biological energy as well, we don't have a way to extract it directly as electricity but it exists

Mechanical and heat is just the most common way to get electricity for us at the moment.

Fun fact time oklo is the only known instance of a naturally occurring fission reactor.

[–] flambonkscious@sh.itjust.works 11 points 2 weeks ago

Wow, that's mental

[–] jaygray91@piefed.zip 3 points 2 weeks ago

An amazing TIL. Thanks!

Face it, all power is water, all stories are Hamlet, all food is grass, and all music is Pachelbel's Canon. Reality's budget is running out and it's having to reuse assets.

[–] captainlezbian@lemmy.world 6 points 2 weeks ago (1 children)

I'd love to see someone try to explain how As You Like It is Hamlet

Both explore how characters must mask their true identities to survive a corrupt patriarchal system managed by a villainous uncle?

I love the description of PV to be basically 'outsourced fusion'

[–] LodeMike@lemmy.today 9 points 2 weeks ago (1 children)

Boiling water is the only reasonable way to turn heat into electricity.

Actually there's also the mirror based solar which boils water in a central column.

[–] rumba@lemmy.zip 13 points 2 weeks ago (2 children)

It's cooler than that; they use the heat to make molten salt, then use a heat exchanger to boil water with that, the salt gets stupid hot and holds energy into the night.

its basically a bowl of water made of solar panels, i mean its not a bad idea at all but its nothing crazy either, probably a bitch to maintain tho.

[–] LodeMike@lemmy.today 4 points 2 weeks ago

Solar uses radiation not just heat.

[–] driving_crooner@lemmy.eco.br 4 points 2 weeks ago (1 children)

Solar and wind biggest energy revolution is not needing to boil water

Photovoltaic panels don't turn heat into electricity. It turns light into electricity.

I’d like to thank some post on Mastadon, which really boiled down how and what a nuclear power plant works to provide power.. the little things.

Can't improve on perfection.

Burgeoning supercritical CO2 turbine technology would like a word.
