Without addressing whomever wrote that... just in general ...
You have to keep in mind that anyone with a keyboard...or that can get into a library... and who can string together english words to where others think they understand what they are saying can post to any forum. No tests for mechanical aptitude, no tests for logical thinking, no tests for mental stability, no nothing.... and wild ideas seem to be attracted to one segment of that same population.
I was once part of a forum where some guys were just sure that they could hook up a leaf blower to their gas engines to act as a legit cheap blower.... and they were angry at me for telling them that did not make sense physics wise....
So it is always best to get second opinions.... good ones have been posted to this thread...
