Intant fruits salad or smoothies !!! :y:I wonder what woudl happen if you tossed a watermelon in the top?! :y:
That's what I thought, tooWOW, the thing is huge, but very cool.
Looks like the Mythbusters "Bust" has been Busted.. :bangpan:
the concept for the martin jetpack was developed in 1981, first prototype was made in 1990s, so its not entirely new. A magazine article I read showed something like 20 prototypes.Seems pretty innovative yet at the same time, I wonder why anyone hasn't done it before...
Actually a company in Walled Lake Michigan developed a jet pack back in the 70's or maybe the 60's. it looked like the one from lost in space, and they also had some that you could stand on and fly. they sent me pictures of them when I was a kid, but can't remember what happened to them. The company was Williams Research I believe.Are those ringfins on the bottom or additional thruster units...

I'm surprised nobody has taken one of those little turbofan helicopter or cruise missile type engines and made a "personal Harrier" out of one by using ducted thrust just like the Harrier does it...

Oh yeah, why didn't I think of that? So with an NRR of, say, 40 db (about as good as you can get), ear plugs or ear muffs bring the noise from one of those down from something like 190 db to a much "better" (?) 150 db... which is still well above the pain threshold. Yes, that would work fine.Have you never heard of these things called air muffs they go over your ears or air plugs, they go in your ears? :roll:
