I'm gonna go with "The Laws of Physics" on this one.

But to get around your question, you can get hot water in about the time it takes to get to the coffee maker at most workplaces because it has a little hot water nozzle on the front. So it heats up over time and then keeps it hot for you, that solves the 5s timer.

And in restaurants you can use what is called a Salamander which does something similar - it heats up to ridiculous temperatures over time, and then you just put stuff you want toasty underneath. For example I just watched a video where they made a bechamel with a poached egg underneath, then got the bechamel toasty so fast it didn't cook the egg.

You can do something similar with a kitchen torch (which, if you have a special someone, and want to be fancy, make them creme brulee with a kitchen torch... besides being delicious it is impressive as hell).
