As it happens, those are the entirely of uses for a flying belt/cage/whatever as an urban transporter.<br /><br />It'd work great if you were the only resident of your city, and everything on the ground was made of concrete and well anchored. Otherwise, not so good. I'd guess that reality is why no one has bothered to build an updated human flying belt/cage for civilian use, even though the needed technology is readily available now.<br /><br />There *are* some military uses...aerial observation robots, mostly...for vertical thrust. It does allow hovering in place in small spaces, such as between trees in forests, where a similar-payload helicopter wouldn't fit. But, those applications don't have much to do with the original human-flight dream. For that, vertical-thrust lift seems to be a dead end.JWillyhttps://www.blogger.com/profile/03243354011523248499noreply@blogger.comtag:blogger.com,1999:blog-3244123422713926575.post-7404549226142091942012-12-17T06:26:36.357-08:002012-12-17T06:26:36.357-08:00Here's a link with a picture of a Chrysler wit...Here's a link with a picture of a Chrysler with Steve Lehto and Jay Leno:<br /><br />http://blog.chryslerllc.com/bio.do?p=view&id=242Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3244123422713926575.post-31554485928130730122012-12-15T22:22:22.418-08:002012-12-15T22:22:22.418-08:00Before the Chrysler Turbine Car, there were the GM...Before the Chrysler Turbine Car, there were the GM Firebirds...I, II and III. I was the ultimate manifestation of the post-WWII design fascination with all things jet-like, with its tubular fuselage, bubble canopy and almost complete lack of automotive practicality. II and III got progressively closer to being "practical", but they remained in show car design territory, intended to generate excitement rather than to be production precursors.<br /><br />A number of years ago the Meadowbrook Concours featured GM as one of the honored brands, and I had the odd good fortune to be standing by one of the many unmarked transporter semis when all three of the Firebirds were unloaded, and Firebird I was jump-started and warmed up by a quite old gentleman...I assume one of the original development team, perhaps one of only a few persons experienced at driving it, asked to come back from retirement...and then driven slowly onto the stage to receive its honors as a design exemplar.JWillyhttps://www.blogger.com/profile/03243354011523248499noreply@blogger.com
