Imaging if this technology could cool a data centre.

Edit: I was not involved in this project. You are wasting your time asking me questions.

They are not new technology the idea has been around since at least the 1980s. There is a reason we don't use them and it's because they are mechanically complicated and inefficient. Those in terms of power use and maintenance requirements.

However with the move to renewable energy maybe that efficiency limitation isn't as much of a problem as it used to be. Especially if it means you can get away from toxic compounds.

Although I have never seen a commercial grade implementation of the technology. It's always just been demos that don't really achieve enough cooling to be anything other than a curiosity.

Not trying to completely throw away your comment here, but I saw this exact same comment repeated ad nauseum about electric cars 15 years ago.
