Every time I see these lava lamps mentions I wonder if there is a more energy efficient way to do this.
How about a bucket of mixed colored beads that is periodically vibrated ? A number could be derived from the order and colors of the beads.
- sigstoat 4y agoyou can amplify noise from various electrical junctions to produce randomness for orders of magnitude less energy than anything involving macroscale materials moving around. there’s no problem left to solve.

- mdekkers 4y agoRandom.org uses atmospheric data, which is pretty cool. `RANDOM.ORG offers true random numbers to anyone on the Internet. The randomness comes from atmospheric noise, which for many purposes is better than the pseudo-random number algorithms typically used in computer programs`
- YPPH 4y agoMeasuring nuclear decay comes to mind. Unfortunately, one service utilising this method, Hotbits, recently shut down their nuclear randomness service. https://www.fourmilab.ch/hotbits/ https://www.fourmilab.ch/hotbits/
- waltbosz 4y agoYou guys all make excellent suggestions, but maybe I should have specified. More energy efficient, but still having a bit of tangibly physical charm to it like the lava lamps.
