Yep, my thought was similar, but more focused on the manufacturing/install energy cost vs energy production.

It all looks like classic vaporware, renderite, and wishfull thinking all combined with a (deliberate or not) lack of scientific reasoning.

The process I tend to use is that if I during their sales pitch find myself asking one or more of the following questions, then it is probably BS.

“Why would they make it that complicated?” “Why no just build a normal ?” “Do they only have CGI and no real product?”
