The video on the website which shows it in motion suggests that it would be a maintenance nightmare, even if it’s scaled up only to truck size, much less railroad/marine/stationary size.
Watching how much motion that thing generates I’d be very hesitent to use it on anything mobile based. I suspect its actual range of use would be limited in a real world situation.
How slick is this ! ! ! and it seems to work, it seems humans are so reluctant to change that steam locomotives never really changed their configuration in 100 years, where were the designers? where were the bright young minds? oh, I guess thats the way it was 75 years ago so we must keep duplicating the way it was, thank goodness someone out there is thinking outside the box.
…Simple it is not. Different and innovative it certainly is. Someone {Green…?}, had a wild imagination creating such a design. There is a lot of action going on in that design…all necessary too. Wildest engine design I’ve seen for some time.
