  Piezoelectricity is the only other I can really think of.

    Why not, though?

    On a serious note: that’s exactly what we’re doing with lighters. At least some of them use piezo elements and not the sparkly wheel thingy to ignite the gas. And it’s real fun to zap yourself with it.

      Yeah, it was a fun journey of learning to look into it. It’s quartz btw. Very piezoelectric and extremely common.

      The conversion rate isn’t great.

      There were talks of using them in sidewalks, but it doesn’t really make much sense really. Piezo almost always only works as energy recovery, which isn’t nothing but you will need the infrastructure which also isn’t nothing.

    Wait a minute, what IF

    Give buskers the acoustic guitar with a link to the grid and every time they play they’ll generate a ton of electricity (in relative terms…)

    Electro-Acoustic guitars use piezos to pick up the audio if you didn’t know

    Even if we used piezo, the movement of the hanger would still have to come from some power source, which would still be the same sources like moving steam, water, or wind.

    piezoelectricity is just simple electric motor

      ?

        piezo crystal is electric motor. you input deformation of the crystal and get potential difference on opposite sides. other way around also works

  All power generation is either solar or ‘make thing spin’, unless we’re including RTGs.

  source

  • rainynight65@feddit.de ⁨1⁩ ⁨year⁩ ago

    But not all electricity generation is based on boiling water. Wind, hydro and tidal don’t need to generate large amounts of heat to make steam that spins a turbine, they just use natural movement to do so.

    • Voyajer@lemmy.world ⁨1⁩ ⁨year⁩ ago

      Yes, make thing spin

    Peltier Effect?

    source

    • Voyajer@lemmy.world ⁨1⁩ ⁨year⁩ ago

      That’s the principle used by RTGs right?

    Solar thermal power…

    • Turun@feddit.de ⁨1⁩ ⁨year⁩ ago

      Yes? Makes things spin.

    All of these are in some way heat engines

    source

    • herrvogel@lemmy.world ⁨1⁩ ⁨year⁩ ago

      Yeah but those heat engines don’t rely on spinning things inside a magnetic field. Heat on one side, less heat on the other side, and you have current. No motors.

      source

      • skillissuer@discuss.tchncs.de ⁨1⁩ ⁨year⁩ ago

        even photovoltaics are heat engines in broad definition

  What about Wind Mills?

  source

  • drolex@sopuli.xyz ⁨1⁩ ⁨year⁩ ago

    Wind is just dry steam

    source

    • spechter@lemmy.ml ⁨1⁩ ⁨year⁩ ago

      Seriously though

      source

      • someguy3@lemmy.ca ⁨1⁩ ⁨year⁩ ago

        That’s condensed steam.

      You know that’s a stretch 😉 but I’ll give it to you. But we are not MAKING wind/steam there.

      source
• ForgotAboutDre@lemmy.world ⁨1⁩ ⁨year⁩ ago

  Hydro power uses running water not hot water.

  Squeezing can be converter to electricity with pizeo electric. Heat difference can be converted into electric directly with peltier devices. Both of these are very inefficient ways to make electricy.

    I’m the spirit of this comment, water is just cold steam.

    source

    • NegativeInf@lemmy.world ⁨1⁩ ⁨year⁩ ago

      How do you feel about water ice being a mineral?

      source
• skillissuer@discuss.tchncs.de ⁨1⁩ ⁨year⁩ ago

  there are also fuel cells

• frezik@midwest.social ⁨1⁩ ⁨year⁩ ago

  The peltier effect can be used to generate electricity from a thermal gradient. It’s not very efficient, though. There’s a reason mechanical means of electrical production predominate.

• Faresh@lemmy.ml ⁨1⁩ ⁨year⁩ ago

  I guess aeolic energy also doesn’t use steam (unless we count the air humidity), but still involves turning a turbine.

  source

  • lens17@feddit.de ⁨1⁩ ⁨year⁩ ago

    Excuse my blatant ignorance, but what is aeolic energy? I’ve never heard about it before.

    source

    • oxideseven@lemmy.ca ⁨1⁩ ⁨year⁩ ago

      Garlic power.

      Nah, just a non-traditional way of saying wind generators like turbines.

      source
    • TheTetrapod@lemmy.world ⁨1⁩ ⁨year⁩ ago

      Apparently it’s the fancy word for wind power.

        or just french

        What a dissapointment.

  Aerokinetics/hydrokinetics as well. With steam, we’re creating the source fluid that turns the turbines to make electricity. Those source fluids can also exist as wind/tides/rivers naturally.
