The post headline is BS. It's 70% more efficient than other thermoelectric materials. Not compared to current compressor fridges. Also no device ever can be powered by its ambient temperature, because thermodynamics says no

Thanks it got me confused, seemed so good that it had to be false but the title was also not very clickbaity.

Edit: opened the article anyway, this is the actual title above the article: Thin film thermoelectric cooling built with semiconductor process technology

I think the userbase of a community being clueless enough to tend to upvote anything vaguely good-sounding is a big factor in me eventually deciding to unsubscribe from that community. It doesn't seem like it is a fixable problem once it develops.

It's a big problem with reddit like forums where the comments are highlighted and much more densely presented than the article itself.

Older forums avoided this (unintentionally) by not having any sorting on replies and keeping the density of replies, low.
