Is there a maximum voltage obtainable by simply stacking transformers one after the other?

What stops me from stacking 10 transformers which each multiply the voltage by 100, getting a compounded 10^20 fold increase in voltage, with an initial voltage of 1 V, each electron would get an energy increase of 10^20 eV, easily surpassing the LHC, so  what stops this from happening?

Darn physics. Again.

First you'll need to account for different levels of isolation. At high voltages it gets hard.

Next - internal resistances. Once your current is down to a few uA that pesky 0.05ohm inherent resistance suddenly spoils the party. Not much left to drive the next stage.

Also you are making a mistake of using voltage as energy. They are not the same.
