  why is everyone in this thread telling me to imagine something

    Because imagination is everything- probably Einstein

  The microwave doesn’t heat your food, it just vibrates the water.

  This is analogous to saying, the blades on a wind turbine don’t go anywhere, they simply spin, and yet power is created.

    You’re just wiggling the saw back and forth, yet the log is eventually halved

      The washing machine just spins left then right, left then right, and the clothes come out clean.

  imagine a bicycle chain between two sprockets, if you crank it foward and back like 1 inch, over and over again, you can clearly transmit power without the chain links going much of anywhere

    Shit, that’s an amazing analogy.

  The balls in the middle of newtons cradle don’t move either.

    Yeah. Sort of like holding two ends of a chain and dragging it back and forth. Even if the chain isn’t traveling the full length, it’s still moving and you could still extract power from the system if you attached something to the middle of the chain.

    Newton’s cradle sounds like a kinky sex move, which is ironic since Newton was likely a virgin.

      In certain kink circles, Newton’s cradle IS a kinky sex move!

  Imagine an old-timey saw with a lumberjack on each side, pulling it back and forth across the tree. The saw just goes back and forth, but effective work gets done.

  Ad on a DC system, the electrons move dozens of times slower than a person walking. They also don’t get anywhere, and power is still delivered.

    It’s fun to calculate that from a socket to a light bulb it may take something close to a few hours for one electron to get to the bulb, but even then that’s an average. Some electrons don’t even get to the light bulb ever.

      IMO, the more interesting thing is how they are all always moving at a large fraction of the speed of light, but over any large distance, they are that slow.

      Things never cancel each other so well on the macroscopic world.

    Hell of a lot of electrons coming out and going in though

  when you touch something we never actually touch it is all just fields interacting all the way down

    just the tip fields

    People are really just mobile energy nets holding other energy in. What if the fields of our energy nets directly influenced each other? Jk… unless…?

  That movement is still energy

  Build a circuit to make use of that et voilà

  Friction makes heat. Same thing really

  In an tidal earth system, the water doesn’t even go anywhere, it simply vibrates back and forth

  source
• Midnitte@beehaw.org ⁨4⁩ ⁨hours⁩ ago

  Presumably the vibrating back and forth causes a net negative charge to propagate down the line?

    There’s a neat video by smarter everyday (and a bunch of back and forths among youtubers, including electroboom) where they show it and argue about it, but the power is actually transmitted through the electrical fields ‘outside’ of the wires.

    Imagine a loop of electrical wire that is 300,000km long. Your switch is at point A, and the light bulb is at point b, halfway along the wire. If the energy truly ‘propagated down the line’ it would take half of a second for the light bulb to turn on when you flipped your switch to complete the circuit. Interestingly, if you make the loop so that points A and b are closer than the lines maximum possibility (or, in other words if you imagine the loop as a 0, the points are at the left and right of the 0 instead of the top and bottom), then the light bulb turns on based on how far apart the points are, not the distance of electrical line between them.

    Nah. Power is just the potential to do work. Clever electrical engineering just takes advantage of the teensy pushes and pulls to do that work. Like pushing a swing, I don’t move but my kid sure can go high when I apply those pushes and pulls at the right time.
