I keep seeing people saying "CPU's that don't generate heat". How exactly would that work? When a transistor turns off/ switches to 0, where does it dump the electrons? Hint: into heat
Sorry, can you explain? My understanding is that transistors don't "dump" electrons anywhere. The gate controls the voltage, which in the `0` state forces resistance to be high enough s.t. current flow through that transistor stops.
As the Veritasium video explains [0], current flow is not a literal flow of electrons, but a state of the electromagnetic field (or something to that effect... it's been many years since my electromagnetism university courses).
There will literally always be heat from computation, that's Landauer. The point is that LK-99 could be or lead to a breakthrough in making computation produce much, much less heat because you're getting rid of most resistivity losses. Which is important, because heat is actually a serious constraint on a bunch of use cases.
