I was also going to make that point about the unbalanced efficiency comparisions within that article.

It just goes to show how the the numbers can be significantly misinterpreted without more comprehensive knowledge of the technology - the author of the article should have known better to compare apples with oranges.

And for the record I though the full system efficiency of the CFU units was around 85 %. The slightly higher Clear Edge system efficiency may be a product of its slightly larger size making efficient heat recovery easier.

But the big thing to remember is that with the world leading 60 % electrical efficiency, the CFU technology is the best by far if you are more interested in power than heat.
