This article on Clean Technica is one of the worst pieces of bad journalism that I have seen in a long time. The headline reads "Terravis Energy Unveals a Heat Pump That Defies Freezing! Down to -57 Below, Shattering Existing Technology Performance".

For a start, there is no such word as unveals. Clearly the author, Cynthia Shahan, means unveiled (apparently she doesn't use a spelling checker), but it makes me wonder what unveals might mean if it was a word; perhaps just keeping a piece of veal until it is no longer fit to eat.

Also, there is the major issue of the temperature specification. "-57 Below" is a kind of double negative, and means 57 above. The question remains, below what? This is clearly an American article, and temperatures are in Fahrenheit, so does the headline mean below zero or below freezing, which are the same in Celsius but not in Fahrenheit, although this is at least clarified in the text of the article.

The problems with the headline make it hard to take the content of the article seriously.
