some washing machines have a dryer included, and i guess one could use asics to generate dry heat for this, but im not really sold on this until i disassemble one of those and actually find a mining operation in there. asics could scale better for an “application” like this rather than expecting to find a gfx or mining card in there with pcix lanes or something which would be rather inefficient and finicky in my opinion.

regarding the upload, of course they could run two schemes: mine and also sell whatever they are recording: there could be any type of sensor in there. and it could record constantly. heck maybe its just something dumb like a bug: looking at that dip between 13 and 15oclock: could be it ran during that slot and then some bug made it reupload the last log or some such thing
