Yeah,and Mythbusters saying that this is a viable solution to traffic,instead of building cities that don't require you to have a car to live in. This program and the ties with the defense industrial complex makes them a mouthpieces for stupid ideas.
7:04 In one of Jamies recent videos he said, that the "this is the 2nd biggest ... I've ever seen" was a joke regulary made by Tory, no matter how big something was you showed him. I love to see, how happy Adam is after saying it. (He mentions it at the beginning of [Origin of "Well, There's Your Problem" on MythBusters] on the Adam Savage's Tested Channel)
I was going to suggest that Tory might be a Monkey Island fan, as Guybrush says it repeatedly....but apparently it's from Get Smart which likely influenced both!
That was the best part of the show I watch it when it aired that year why I'm watching it now is I want them to use that more powerful engine with shaft drive not belt and see what it can do
More speed doesn't actually get you anything. The engine needs to have enough torgue to spin the props. If you gear it then the engine could easily stall.
There'll never be flying cars... people can't even drive down a straight road without crashing in to each other, imagine tonz of flying cars falling to the ground...
Funnily enough, with the quadcopter tech and flight electronics today, you probably COULD build an electric jetpack from plans on the internet. Gravity Industries Jet Suit aside (which, incidentally, Adam's been flying on), multiple drone based jet packs do exist.
There is still the safety concern. There is a reason personal flying devices are never going to be a commercial product. They are too steeped in liability. Remember people, if your device fails while you are in the air, you are falling to the ground with no safety net.
They need some sort of parachute mechanism that auto deploys when it detects its falling past a certain rate. Problem with that, there is a minimum height for parachutes to work properly, and even then, what's going to help you below that minimum altitude?
My guess would be on something psychoactive. He was not really there at all. But then I'm not experienced with drugs at all (other than the legal ones aka nicotine, alcohol and the internet), so I can''t tell for sure. Never seen someone as far past normal on weed either, so that's probably not it...
I speculate that the jetpack test failed because the propellers were not spinning fast enough. Someone building a machine like that would first check the specs of the propellers, in particular the fastest speed at which they generate thrust efficiently. Then the builder would select a gear ratio that would make the propellers spin at the highest speed allowed at the engine speed with the highest level of power output. It's possible that the engine would not be strong enough for that, so there might have to be experimentation with gear ratios. With no professional background in aeronautical engineering, I speculate that the main purpose of the cowling ducts is to prevent turbulence, as well as directing the thrust. Drones fly well enough without them. The Mythbusters made a good presentation, but I'm not fully convinced that the myth was busted.
The myth though was that someone without a background in aeronotics can do this and the mythbusters do have a lot of experience in engineering and a lot of contacts. If they can't do it then it's pretty clear some middle class guy in his garage can't do it either and that was the myth. That a ducted fan machine can lift a human is no myth, I mean all you have to do is scale down a helicopter. The question is can an average Joe with only a lose idea of mechanics and a single trip to the hardware store do it?
Cowlings are about scale and also compactness. For this application they wanted a lot of lift in a small form factor. With a helicopter you would just put bigger rotor blades on it and with a drone you can get more thrust for less additional weight by just adding an additional propeller. With this design though using a single engine having like 4-5 fans would require so much mechanical complexity it would not be reliable and would have added too much weight. They didn't yet have the powerful batteries and electric motors that allow drones to have up to a dozen rotor blades without being too heavy or become too unreliable. So if you can only use 2 rotors and they can't be too long then you have to add cowlings to maximize the thrust from them.
I'm going the tin foil hat route on this one. With it being TV and the FAA involved probably had the biggest hand in why this wasn't a successful experiment. Adam and Jamie are waay too smart to not be able to figure it out especially when smart guys like them are actually interested in the project.
the props where all wrong . not the speed. was the wrong design for what they needed. example: a drop prop is different from an airplane prop . after a a certain speed of am airplane prop it become inefficient , reaching its max performance speeds. had these been drone props designed for hight speed . this thing would have taken off
Personally I'd love to see an update on the Williams X-Jet, also known as the flying pulpit. I know someone had bought the rights and patents for it. Thing looked amazing.
You'd think with the Build Team doing the most implausible woo-woo myth the show's ever covered, their "expert" would be the biggest scammer in the episode, but that Skycar fellow is on another level.
once i was bored so i got a few people to attempt some "realistic" flying in some game and ngl, humans are relatively horrible at flying and considering that we haven't evolved at all to fly and even birds tend to crash against the walls sometimes, i can easily tell that giving people an access to flight irl would have disasterous consequences, at least we would have to train people first and then be more strict than in case of cars, perhaps just as much as it is the case for planes... and even then you have to make sure that there's absolutely zero technical issues and have backup engines
The Primary obstacle for personal flying machines is the incredible complexity of piloting in 3 dimensions. Look at all the accidents on roads, where there are strict "pathways" and rules - increasing to 3 dimensions would make traffic control impossibly complex. And that assumes the actual craft is somehow flown "automatically" eliminating the need for the pilot to have the extensive training they now require.
Why did they decide to move the engine lower on the frame? I thought the pendulum effect didn't work on helicopters because the thrust is not vertical like a fixed hinge.
Just a comment on an interesting effort with this one-men flying machine.. The stability experienced by the Hiller machine and the De Lackner Helivector was due in main to keeping the cemtre of gravity ABOVE the rotor system. To install the engine low in the craft would make the thing VERY unstable. It might seem to be the logical thing to do but entirely wrong in this case.
37:18 Jamie: What do you want to do? Pave the whole planet with roads. Highways are getting full. Americans will literally try everything to solve traffic instead of actual public transportation lol
They maybe would got some more Thrust, if they played with the gearratio of the Belt drive and or the Dimensions of the propellers (bigger or smaller but with less or more angle on the blades) BUT I am amazed and impressed how much has changed in these few years. Today we have working Jetpacks of different kinds. There are Electric ones with RC Brushless Motors. There are Turbine powered, also on base of RC Jetengines And I belive I saw some with gas engines. Also there are kind of Jetpacks like a German Guy with a flying Bathtub with RC Equipment. Its a manlifting Quadcopter.
Anyone know what the graphic is on Scottie's shirt at 8:42? I've definitely seen that character in the purple dress before and it hit with unexpected nostalgia
Did the jet-pack reappear in the later episodes? Like the pneumatic actuators from the marching bridge myth EDIT: Found one in the build team using it as a windblower, and in the Mythbuster exhibition
This was a good episode, they were very close. Could the ratio be changed to spin the rotors faster, it looked like 2:1 reduction. Maybe if constructed of tubing like aeroplanes are rather than girders the weight would be significantly reduced.
That flying machine duct fans reminds me of my sump pump when it jammed with sand and talking to a wonderful DeWalt tech about the tolerances. I think it would need precision measurement of the blue foam. I am not in any way blaming Adam. I expect you need to spend in excess of $50,00 to make this accurate to 1/16"
Sorry but got to ask....... Wich 3d printer is you go too printer. Ive a neptune 4pro (all your fault😊) but at the time was looking at the bamboo range. Any chance of doing video with your thoughts on all your printers . Always great videos . Thanks
Belt slipping? maybe variable pitch fan blades needed in order to maximise efficiency at max power? (I used to be a hovercraft builder many years ago and am jealous!)
I think that if you could increase the diameter of the central pulley that is on the central axis of the jet pack, it would considerably increase the rpm of the propellers. There was just one thing missing from the video and descriptions. Where did you get the source for this project file?
It's a shame they didn't research outside the US. In NZ the Martin company created a workable jet pack. Similar to what they did, only it worked. Could fly to 5000 ft at 60 mph tested and was quite stable with a parachute return system. But hey. If it's not invented in the US, it's just not invented...
Jamie is right that there's no backup, but that's why you'd mount a parachute on the flight pack. i don't even call it jetpack, it's flight pack. those designs where horrible indeed, but it's perfectly possible. you need to make quadcopter like design with 4 propellers, not 2. it gives stability and obviously twice the lift. also instead of high RPM, use more blades per propeller. it's common sense, more blades = more thrust at lower RPM. you need to find that sweet spot where RPM to amount of blades to weight ratio is perfect, so it gives maximum amount of lift considering the weight aswell. power them with single engine and make sort of a "gearbox" that would allow to slightly adjust speed of each propeller, which would give you control. it's totally possible, but not by following those hillybilly designs.
The real problem with this is the props were not spinning fast enough to generate lift. The engine driven pulley needs to be 10% larger than those driving the propellers. Another way is to use propellers with more blades.
To the pyramid myths, something scientists found out and what me really surprised is that the Gizeh pyramids have (like mountains) such a big mass that they do slow the time around them a tiiiiiiiiiiiiiiiiiiiny tiny bit. Not noticible and not measurable unless you have billions worth of lab Equipment but i think thats pretty cool. Like Einstein sayd, big Objekts can influence time and room. Like light bends around massive stars and black holes.
Even if those things were working great, be safe - and affordable (spoiler: They're not) - they still have the big problem of terrible fuel efficiency. Unless we have loads of free energy - these things will never be real. But hey - if I'd dumped 200 million USD into this - I'd probably believe that, too.
And the idea isn't new. The whole "flying cars" idea is around since the 50ies - at least. And it still all comes down to efficiency. Unless you're able to build a VTOL glider - it won't happen.
@@themonsterunderyourbed9408 Yeah - right. Where did I left it? Behind the time machine, left of the warp drive - or near the trans-dimensional travel device?
That private Helicopter would maybe fly easier If you increase the Diameter of the Rotors (and ducts). You get way more airflow/mass and dont get too mich weight ontop
It's kind of amusing because with current electrical engines this isn't a problem at all. Have you seen the platform ones with the small propellers that people get off into the air with these days? Turns out that what you really need is a better motor because ICE's efficiency is ~40% at the very best and have a rev limit, electrical engines ... not so much.
The first big design mistake is not to use rotary colt propellers, we need too much power and the lack of carbon fiber makes it unfeasible ...... I love this program the most
LOL I remember seeing this "pyramid power" thing on Brazilian TV back in the days and I did put a banana for a month inside a paper pyramid. I dunno it did rot but not so much so kinda worked? Or was it a placebo effect of sort? Anyway it was quite unimpressive.

Also why didn't they use gears to increase the speed 🤔
The extra weight would probably just have negated any increase in lift.

You just would need to put a bigger pulleys on the engine for the belt.

those designs where horrible indeed, but it's perfectly possible. you need to make quadcopter like design with 4 propellers, not 2. it gives stability and obviously twice the lift.
also instead of high RPM, use more blades per propeller. it's common sense, more blades = more thrust at lower RPM.
you need to find that sweet spot where RPM to amount of blades to weight ratio is perfect, so it gives maximum amount of lift considering the weight aswell.
power them with single engine and make sort of a "gearbox" that would allow to slightly adjust speed of each propeller, which would give you control.
it's totally possible, but not by following those hillybilly designs.
It's kinda funny watching this episode now that we have the personal jetpacks made by Gravity. www.youtube.com/@GravityIndustries
The real problem with this is the props were not spinning fast enough to generate lift. The engine driven pulley needs to be 10% larger than those driving the propellers. Another way is to use propellers with more blades.

That pyramid dude took too much acid one time, never came back and is permanently trippin. He's on a permo! xd
To the pyramid myths, something scientists found out and what me really surprised is that the Gizeh pyramids have (like mountains) such a big mass that they do slow the time around them a tiiiiiiiiiiiiiiiiiiiny tiny bit. Not noticible and not measurable unless you have billions worth of lab Equipment but i think thats pretty cool.
Like Einstein sayd, big Objekts can influence time and room. Like light bends around massive stars and black holes.
We have a say in the RC plane flying community, “Take offs are optional, but landings are compulsory”, landings ….that’s your problem!
Perfect for big cities and there traffic jam problems.....
go for it!

AluminIum! There are 2 i's.
36:46 Ten years huh? How did that prediction work out?
Not good, motel, not good.
Even if those things were working great, be safe - and affordable (spoiler: They're not) - they still have the big problem of terrible fuel efficiency.
Unless we have loads of free energy - these things will never be real.
But hey - if I'd dumped 200 million USD into this - I'd probably believe that, too.
And the idea isn't new.
The whole "flying cars" idea is around since the 50ies - at least.
And it still all comes down to efficiency. Unless you're able to build a VTOL glider - it won't happen.
@@stanislavczebinski994 not true. All we need to come up with is some type of gravity manipulation technology.
@@themonsterunderyourbed9408 Yeah - right.
Where did I left it?
Behind the time machine, left of the warp drive - or near the trans-dimensional travel device?
That private Helicopter would maybe fly easier If you increase the Diameter of the Rotors (and ducts). You get way more airflow/mass and dont get too mich weight ontop
Now, there's real personal drones
And jet packs. ua-cam.com/video/nj-Iwv5NJKg/v-deo.html
Obviously Jamie's moustache is too heavy, if he shaved it off, that contraption would easily fly!
Where South went with North E. West?
Where all his working plans went - south 😁

Really tho lol

41:46 why does Adam have a Jafar knife (for all you Stargate fans, you know what I mean)?
Maybe he's a Stargate fan, too... 😊
Incidentally, it's Jaffa, not Jafar.
Why wouldn't you put a groove in the ducts so there is zero gap between the fan and the duct?
Those props dont look to be counter rotating which imho is a rotational torque reaction challenge looking for a place to happen
It's kind of amusing because with current electrical engines this isn't a problem at all.
Have you seen the platform ones with the small propellers that people get off into the air with these days? Turns out that what you really need is a better motor because ICE's efficiency is ~40% at the very best and have a rev limit, electrical engines ... not so much.
welp, 20 years into the future and I can confidently say that Dr. Moller is reasonably full of shit.
Well,, We still don't have cars that can fly us to work everyday... Maybe 20 jears more, or never in our lives. 😉
I do still wonder if there'll ever be a backpack based jetpack like the Rocketeer... 🙃😅
Im sure the first jet pack was made by someone at home
me and my buddy tried building a jet pack in grade school.....it went as well as you would expect
the Bell jet-pack was in one of the early James Bond movies
The first big design mistake is not to use rotary colt propellers, we need too much power and the lack of carbon fiber makes it unfeasible ...... I love this program the most
Jet engines! Modern compact jet engines seem to work. If only for 15 minutes. ua-cam.com/video/nj-Iwv5NJKg/v-deo.html
3:20 "Extremely dangerous" 2024 with available ones on the market, police using them and taxis ready to be deployed XD
Huh, where are police and taxis using jetpacks?
That pyramid one was borderline insulating
14:54 Adam reminds me of a monkey witnessing a magic trick lol
LOL I remember seeing this "pyramid power" thing on Brazilian TV back in the days and I did put a banana for a month inside a paper pyramid. I dunno it did rot but not so much so kinda worked? Or was it a placebo effect of sort? Anyway it was quite unimpressive.
I think they should have tried an electric version. Probably a lot lighter,and just as powerful. They sell motors for paragliders that are electric.
