To be honest, I was just waiting to see this happening and I'm not surprised that it's the chinese aswell. How effective can this be tho? I mean even if it's a smaller specialized mining chips, so how profitable can they actually be? Also, would you every household appliance like that?
i don't think anything about this is effective or even efficient. this sounds more like a joke to me than being something that actually happens in the real world! and besides some of these things will overheat and die if you insert a mining chip inside them or you'll have to add additional cooling system just to cool down the chip.
and it is "cease" to amaze not "seize" as far as my English tells me

My thought goes to this post when I had read that article I don't know what to say and think I might laugh on this idea thinking how can this work? well seeing your post that regular appliances may overheat due to the process of mining I would say that they would simply put some cooling system just like you thought but I'm afraid that the price of each appliances would be costly because of the extra build needed for it, and a miner rig cost a lot so a double purpose machine might really cost a really a lot.
