Please take a moment to go out on a limb and read the video description or watch the video.
The video is discussing a new technology from a company which purports to have come up with a more efficient way of compressing refrigerant in cooling systems, https://www.magtor.tech
Fair enough, I stand corrected. I think your link would've been a better submission than just the video specifically.
The submission lacks '[video]' and took me a couple of seconds to decide it wasn't for me, just in terms of presentation style even after you made it more appealing.
Can no longer edit, but the submission has been updated to remove the silly click-baiting ('revolutionary'), and to add '[video]'... I don't know if the flaggers and down-voters missed the earlier title so lack context, or what, but it's sorted now - I take no issue with the current title 'How can we make air conditioners more efficient? [video]', that's not what my comments above are referring to.
