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
- Don't throw mud. Behave like an intellectual and remember the human.
- Keep it rooted (on topic).
- No spam.
- Infographics welcome, get schooled.
This is a science community. We use the Dawkins definition of meme.

Most engines are less than 30% efficient at producing movement. The majority of the energy is lost as heat.
Thermodynamics tells us that pretty much all energy ends up as heat. In a closed system, any device that uses energy is 100% efficient at making heat. A 1000W computer will make exactly as much heat as a 1000W heater.
A 100% efficient engine can only exist if the desired output is heat, thus making it a pretty useless engine. Also, in a closed system, the exhaust cannot leave.
All space heaters should be coin miners (or some other borderline useless energy wasting tech, like AI training). Change my mind.
We have enough of a chip shortage, tyvm
If you want to be philanthropic, there are programs you can run that use your computer's idle time to process data for cancer research and such.
You can sign up for research crunching.
