Did the gravity-powered plane needing hardly any fuel invented by Robert Hunt get made? We could use one now!

I found references online from 2003 to 2006 but nothing newer. Here is the last one I found so far. Interesting. Do you think it would work?

His idea is like totally bogus. It always takes more energy to compress and expend his "anti-gravity" balloon gas than you can ever get back from it. Perpetual motion is a no-go.
