Thats like the first "Super duper future things that you may see some day" thing that I was partially convinced by.  I like on the discovery channel when people take unproven/unsave/unpractical ideas and make people think they might work in our lifetime, like that shitty flying car idea they were pushing for a bit.  I was thinking this was another one of those, cus all of the jetpack things ive seen on tv have only been operated when the pilot is tethered to a crane and they fly for 5 seconds (same with the shitty flying car)
