What about electricity renders it impermissible on Shabbos?
The Chazon Ish holds it is boneh. Others, I believe, hold it is m’saken mana.
I think that it is pashut that this is no better than chuk tochos.
Do you have a source that “chuk tochos” is muttar on Shabbos?
Would hitting “print”, activating your computer’s printer to produce a sheet of writing, be muttar according to you?
