This sort of thing is used, e.g. [0].
It collects entropy at a limited rate, though, so for demanding applications (SSL servers, say) you want dedicated hardware: [1], [2].

- malandrew 13y agoHow do those Entropy Keys work? What sort of environmental random data does it rely on for creating random bits?
- wiml 13y agoThermal noise of various kinds, usually. (Edit: that is, the noise introduced in a circuit by the fact that it's not at absolute zero, e.g. Johnson noise. Not just gathering entropy from a temperature sensor reading or something like that.)
