Welcome to c/science_memes @ Mander.xyz!

A place for majestic STEMLORD peacocking, as well as memes about the realities of working in a lab.

Rules

  1. Don't throw mud. Behave like an intellectual and remember the human.
  2. Keep it rooted (on topic).
  3. No spam.
  4. Infographics welcome, get schooled.

This is a science community. We use the Dawkins definition of meme.

Producing acid batteries, or any batteries isn't power generation. It's turning chemical potential (which was generally produced in an energy-consuming process) into a storage device for electrical potential.

Induction is just changing the properties of your electricity, not generation.

They are all just ways of converting energy from one form into electricity. Every single one of the ways we "generate" electricity ultimately comes from gravitational energy. By the time we use it to power electrical circuits, it all has gone through various energy-consuming/losing processes.

The list wasn't so much a "ways to create electric energy that aren't spinning turbines" as a "power sources for electric circuits that aren't spinning turbines", which is why I included chemical and electrical, even though they often aren't very useful without another source of electric power.

Fair enough. As you said, none of these are net producers of electricity if your thermodynamic system is big enough to count as closed.
