That's approximately 100 lava lamps each at 100W = 10,000W = 10kW/h * 20.4 cents = $2.04/h * 24 = $48.96/day $1,489.20/month. Ignoring the fact that is very li

That's approximately 100 lava lamps each at 100W = 10,000W = 10kW/h * 20.4 cents = $2.04/h * 24 = $48.96/day $1,489.20/month.
Ignoring the fact that is very little money in Silicon Valley. Lava lamps consume a large amount of electricity in order to generate the heat they need. There are cheaper better ways to generate randomness, this is purely for spectacle clearly.
It makes me nervous more than anything. If that's the front they put up, inside is there a Rube Goldberg machine that triggers DDoS protection?
- pbhjpbhj 9y agoThey should "power" the lamps with excess CPU/processor heat.
- hinkley 9y agoNot too much power though. They can explode.
- ams6110 9y agoIIRC a standard size lava lamp used much less than a 100W bulb. So your costs are maybe half that.
- adzm 9y ago40W on mine fwiw
- hinkley 9y agoAs someone else pointed out, they overheat. So if you want to run them all day you might go down to a 30 or 25 watts. But there are probably a bunch of other Brownian motion machines you could use that take a lot less power. Like those glitter lamps. You’d need a higher res camera.
- JdeBP 9y agoInfinite improbability is just around the corner, eh? (-:
- techman9 9y agoI think the intent is for this to be a functional art installation more than anything. Of course there are less expensive (and more "practical" ways of accumulating entropy), but this is a very cool art project that provides a pretty core function. Yeah, maybe it's kind of expensive to run, but that's not that extreme. A lightbulb is like 100W too right?
- NightlyDev 9y ago100 watt is way too much, 25W/each is a more realistic number.
- bjoli 9y agoIf you want to go with lamps or light as the source of entropy and still have a nice wall to show people, plasma globes are probably a better way of doing it.
