So each button copies a piston of different temperature which changes the length it extends by every spark. This means if you spark in 2 binary numbers they will be added. The output is decimal though so is it usefull? This is a concept save so it's bad.

    You should build a computer based on this concept. +1

    To put it into formal terms, this adder as a space complexity of O(2^n), while the average ripple-carry adders have O(n). (where n=bits)

    Yes, but the size gets bigger very fast for larger numbers. In that case you may want to consider another type of adder.

    @JustAPlayer you just need to spark it twice. This is just a quick proof of concept nothing fancy.

    where is the input for the second binary number?

    it's cool but it could definitely use some refinement, maybe separate per 10^x?
