apparently you don't really know what clickbait is, though i do know what you mean, and i think thats correct, though not more correct then to say the title has a clickbait factor.

And if you think this title wasn't thought of to maximise clickthroughs (again, regardless of the content of the article as clickbait ONLY applies to the title) ... you are very naive..

Other titles could be, getting rid of excess heat via infrared into space. Which would be less interesting to majority of people, as people read it, and think 'oh airconditioning, i got that... oh a new unit that beams into space ... neato...'
