[X] Donate it: A museum in Gotham wants to take it off your hands as an example of Gothams history, it'll be out of your sight at the very least. Gain a large sum of money and minor increase in political support.
[X] Leave it be, but cut the power to be sure: The Chairs present angers you greatly and makes the prison itself more aggressive in foiling escape attempts. All escape attempts to make a roll to see if an unforeseen complication foils it.
[X] Destroy it!: The chair is destroyed and salvaged for some parts that can be repurposed to use in the future… super science has actually been around for quite some time as it turns out.
[X] Sell: One of Gothams richer detezines wants the chair for some reason and is willing to pull some strings for you in the future to get it. Gain a smaller amount of money but gain a major backer.
