Second law of thermodynamics? The electron and the environment have the same temperature. If it falls, it emits energy warming the environment without consumption of energy. But this is impossible.
For example you can make a very similar system with a positron and an electron https://en.wikipedia.org/wiki/Positronium . It's stable for a while, and it has very similar properties and levels like an Hydrogen atom. So the "second law" should apply too. But it has a mean lifetime of only 0.12 ns (1.2E-10s).
The second law consider also the properties of the materials. For example there are small bags with sodium acetate that are used as hand heaters https://en.wikipedia.org/wiki/Sodium_acetate#Heating_padhttps://www.youtube.com/watch?v=Oj0plwm_NMs You put them in hot water, the content dissolves, and you let them cold to room temperature. When you click the metallic part, they crystallize and release heat.
Another example is connecting a small lamp to a battery. It release light and heat, specially if you can get an old incandescent light bulb.
This is much more dangerous than the AI itself.
