hello. I usually frequent the paranormal board but i need help from people who regularly "create useful things". so i have discovered 2 ways of possibly creating a personal flying platform/craft. There is the WASP II flying jet platform(as seen in picture). the youtube channel that posted the video below about the wasp is the project manager and probably has alot more info if you can contact him. Then there is Victor Grebenikov and his flying platform using anti gravity beetle wings. I have a few hundred of the shiny blue/green bug wings but they need an electrical charge to show any effects.

Is a load of fucking bullshit. All that crap about how we don't understand how bugs are able to fly has been disproven, we understand how insects fly and there is no need to invoke fucking crazy antigravity. Flying platforms like the wasp aren't rocket science. You use a powerful as fuck engine to push air down. Small jet engines have become powerful and common enough that well off people can actually buy them.

At best, you'd get no more than about 15-20 mins of actual flight time out of that. The main problem is the lack of anything using air for lift, like a wing or rotor. Due to this limitation, there's nothing in existence with enough safe power density in which to fuel the device for very long at all. Due to this limitation, the usefulness of such a device is also extremely limited. The best use, anyone has brought up in past threads, has been for first responders getting to local emergency situations. Even then it'd be hard to beat a standard Ambulance or Firetruck. Thus, it is further regulated to areas of less or no road access.

FYI, there are much better designs with better efficiency and range...

>>1448873
>Are you an entomologist?

Not him, but I am. "Bugs" use their Elytra to cover their real wings. The underwings are at the proper humeral angle in which to pivot and oscillate in order to achieve normal flight. Flight dynamics are rather simple, yet elegant. Mr. Grebennikov's platform if "fake" and nothing more than a powered pogo stick at best and him just jump-lifting it at worst; photographed while bouncing.

Those are tethered to their fuel source and have unlimited flight capability within the range of their tether. Again, the problem is power density. Untethered, they are useless.

>>1448889
Nothing wrong with "bug" wings, per se. The best design would be dragonfly wings, though scaling that up is rather difficult due to the lack of proper materials science. The wings themselves flex and bend greatly. The closest things I can think of are slightly-articulating wings of some jet craft and shape-memory alloys that change shape when a current is applied. While not used specifically for wings, that technology is used in aeroplanes. I can see it being used for very tiny craft similar to tiny drones and such.

Regardless of what you create, the power density issue is what is stopping every good idea and all those cool sci-fi ideas. That is why in sci-fi you have the technology using something that only really exists in that sci-fi universe to make all the cool shit happen. That may be magic, unobtainium, Iron Man's arc reactor, zero-point energy, cold fusion, anti-matter, etc. Basically, the power source hold up is what borks everything for everyone. Hence all flying craft using wings and rotors of some kind. That is also why fossil fuels are use above everything else for serious business. Its power density and easy of use is better than everything else.

You seem rather unfamiliar with fields you are attempting to approach and the interplay of between them such as aerodynamics and energy. The kneejerk reaction would be to take your conspiracy theory at face value, to call you stupid, and jump to the next thread; as some have and will do here. >>1448873 Your response here especially belies your age. But you have a dream of owning a personal aircraft and I can respect having a dream. However, you need to learn when to be objective. This beetle wing theory has all the hallmarks of being a hoax.

1) research was done by a foreigner with a different language
This makes it easy to claim things that are harder to verify due to the language barrier. (Bonus points for Russians and Germans)
2) research was done alone
Any scientist worth his salt would collaborate, confirm, THOROUGHLY DOCUMENT, and patent his research.
3) Sounds like there's money involved
Not sure where you got your beetle wings, but I bet it's from someone who claims to have successfully repeated the experiments without solid proof or documentation of their own.

Not you have 2 options going forward. Realize you've made mistakes and cut your losses, maybe have a good laugh about it later on in life; or ignore everyone who disagrees with you and your unfounded beliefs and blame your failures on others.

You want my advice? Start small. Have fun. Make a quad copter. Or else you're going to spend all your money on wings that will never fly.

I think he meant "H2O" since that is what those jetpacks do use at the theme parks and such. "H2O2" is an alt name for "Oxyhydrogen" which is mixture of H2 and O2, but they are not bonded together as actual H2O2 (hydrogen peroxide), but normies don't know the difference so they call oxyhydrogen, "H2O2". The oxyhydrogen is made from electrolysis and is crazy explosive and extremely power hungry to make. It is what you see people rigging up their vehicles thinking it gives them better fuel mileage. It is terrible as a booster fuel because you can't store it for long term. You need to create it then use it or it will actually leak out through the walls of any container you place it in.

This anon >>1449039 doesn't realize this and thinks these are rides you can ride yourself, which isn't true. Only stuntmen performers do that stuff since it can end in an unspectacular death pretty quickly.

However, this webm shows an H2O jetpack you can use at theme parks. They are awesome. There are jetpack versions and flyboard versions. Google, "Jetlev Flyer."

There are ways of getting around this fact/ this isnt always completely true.The hutchensin effect has shown to levitate a 50lbs steel ball with about 14w of power or as much as a light bulb needs to power. Bob Lazarand the element he said powered the ufo reactors he worked on. magnets with copper wire generating enough power to light a light bulb. Oronite witch is a combination of organic and inorgaic materials in concurring layers has also shown a decent power affect. There is also the stuff about the joe cell and water flow and sound dynamics achieving a huge rate of efficiency through simple means of tuning forks and certain angles to maximize fluid movment. i think if you combined a few of these it would easily be possible.

Well the issue of energy density isn't necessarily the problem here, like it is with laser weapons or photon propulsion. Hovering theoretically takes no energy at all (from a classical perspective at least); since you are not accelerating across a distance no work W=m*a*d is done. To move a 100kg machine+human up 10m it would take 10kJ, which is about the energy stored in a high capacity 18650. It's a lot, but not unfeasibly so. Switch to combustable fuels and it's shit-all. The problem is that 0-energy hovering requires some sort of support force. Buildings do this with the physical strength of concrete and steel, but to do so without contact you will need a force field of some sort. Electromagnetic and gravitational fields are about all that fit the bill, and both come with big problems.

Creating an "anti-gravity field" is impossible without several hundred thousands of dollars of equipment and still won't be able to effect anything not on an atomic scale. Non-gravitational fields need some sort of reference to push against, be it the natural magnetic/electric fields of the Earth or artificial ones. Using artificial fields has been done countless times successfully, just look at those active hovering pot-plants on ali, standard bismuth/superconductor diamagnetic levitation experiments, and electrostatic levitation like the oil drop experiment. But making such a system stable without using extra energy and making it able to carry significant weight is the issue with all of these. A magnetic levitator needs to use diamagnetism to be passively stable, since a diamagnetic (permeability < 1) material will expel magnetic fields regardless of polarity, so there is no inherent instability caused by the hovered magnet flipping over. We don't have such substances when it comes to electric permittivity, but thankfully we have electric monopoles/charges, which is what causes the stable hovering of moon dust: https://en.wikipedia.org/wiki/Electrostatic_levitation..

>> No.1449691

>>1449683
In addition, ionocraft and the Biefeld-Brown effect hover by way of imparting momentum to particles, so are not passive and require power to run.

The reason why rockets fight against gravity while accelerating as much as possible (ignoring air resistance) is because 9.81m/s^2 will always be subtracted from your gross acceleration, regardless of whether it's 11m/s^2 or 100m/s^2. Each m/s^2 of acceleration ideally takes the same amount of energy, so going slow or hovering is innately inefficient. The efficiency (amount of acceleration dedicated towards accelerating upwards as opposed to fighting gravity) can be expressed as E = a_net/a_gross = a_net/(a_net-9.81) = 1/(1-(9.81/a_net)), so as a_net increases the (9.81/a_net) will approach 0 hence the total fraction E will approach 1. Helicopters and tilt-rotors and VTOL jets all have this issue that they're burning fuel when they're not going anywhere, which is why electromagnetic levitation is so appealing compared to the aforementioned jetpacks.

But it's relevant to the thread. Bug wings do not make something hover like OP thinks they do, only way to get stable electrostatic levitation would be with a very high voltage since bug wings will be a dipole if anything. Plus the planet's electric field will hardly be uniform.

Let me clarify. For helicopters, jets, etc. hovering then yes energy density is the main concern because you're always wasting energy on imparting momentum to the ground inelastically. But in this thread there is both discussion of that sort of hovering device and electrostatic hovering. Just as a magnet can hover in steady state between two slabs of bismuth, the same can happen with electrostatics. Simply an equilibrium between repulsion and attraction forces. The Earth constantly produces a force of gravity, and as do magnets with magnetic forces. This produces a potential energy gradient around which things can be attracted or repelled from. By creating an equilibrium between two or more fields you're not requiring that anything use up any energy other than its own potential energy. To change that equilibrium and move the hovering craft you do need to put in energy, but my original statement "energy density isn't necessarily the problem" was alluring to the fact that this energy is likely insignificant compared to that wasted on hovering inelastically.

H2O2 stands for hydrogen peroxide not oxyhydrogen. Hydrogen peroxide is a monopropellant. You pass it over a bed of catalyst and it turns into hot steam.
https://en.wikipedia.org/wiki/Jet_pack#Hydrogen_peroxide-powered_rocket_packs

They are probably the easiest personal flying device to make. Really all it takes is a bit of plumbing, hydrogen peroxide, and some balls. A rocket belt is just a pressure tank, H2O2 tank, catalyst bed, nozzles, control valve, and straps. The most difficult part isn't even building it, it's obtaining and handling high purity hydrogen peroxide. You have to make a special still to purify it from the stuff you can actually buy. It's crazy dangerous stuff too, light sensitive, heat sensitive, corrosive, reactive with organics, it can even turn organic stuff explosive too.

>>1448947
Power density isn't the problem here. Hydrogen peroxide, lithium ion batteries+brushless motors, hydrocarbon+ic engine have enough power density to lift their own weight plus a human. The problem is that they cannot do so for very long because of the energy density. Of course the energy of gasoline won't be changing anytime soon, but we can find ways to use it more efficiently. Those small jet engines probably aren't operating at their thermodynamic limits. If we can find a way to make them run hotter, say by making them out of ceramic rather than metal we could push the efficiency up. Even better would be if we found a way to directly use the chemical energy of gasoline rather than having to convert it to heat first. There is nothing that says we can't directly convert the chemical energy of gasoline to mechanical work!

Thanks for the input. A personal flying device like the jet pack or even a platform or board are too inefficient.

so what about the best/cheapest design for a personal flying craft/vehicle? like a doc brown,s delorean, jet set moto 1/2 flying/hoovering jet ski ps1 racing game, or even like a mini heli or something.

p.s. Also discovered a pretty interesting paranormal being/history yesterday. If the info is correct, then its probably one of the biggest red pills out there so be careful. If you dare to look go to google and search "Emerald Tablets of Thoth".

I'm thinking a mini autogyro, since you don't need a large supported wing. Props are almost certainly the way to go, but trying to make a tiny high-bypass turbofan could be interesting. A tiny helicopter could be good, though fixed-wing aircraft are usually not very spatially efficient, at least for storage.

Electric vs internal combustion vs jet vs rocket is a question for another post, but all have at least some merit.

Meme terms, discovery channel talking points...None of what you said means anything. Space is a pressure mediation, time doesn't fall out of the realm of concepts (it doesn't exist). "Dark energy", "Dark matter"...these are more empirically untrue than particles themselves, it is nothing other than corrections in equations.

Right. But that's a meaningless position to take, because not only does it work regardless of why it works, but we have an understanding of almost exactly how (not why) it works and wondering why it works is as meaningless as wondering whether there are other universes out there, or whether intelligent design or the anthropic principle are the case. All are outside our ability to ever perfectly understand, at least as far as I see it. If we obtain a perfect theory of everything that explains exactly how all forces work there will still always be a question "but why?" that will remain unanswered, lest we actually find evidence of intelligent design or some other improbable explanation of why something exists. We just have to deal with what we've got.

Power density isn't the main problem here and your video proves it. We can make very power dense devices like that helicopter, but due to limited energy density it cannot carry out maneuvers like that for very long. That helicopter uses a 5.1 KW motor and has 2 22.2 volt 5200 milliamp hour batteries. So the stored energy is 22.2 volts *2*5200 milliamp hours=831,168 joules. So if we're running our helicopter at full power, it will last at the very max about 831,168 joules/5.1 KW=2.7 minutes.

You're right, instead of figuring out why things work, we should just leave it in the realm of human concepts and make assumptions and hypothesize on false premises. Then we can continue limiting ourselves on using concepts not based in reality. We will quantify things of qualitative value simply because things in our reality must be countable. The quality of things will not matter, only what quantitative separate and indivisible units they have.

Useful for recreating the same flawed observations, but an absolute failure at explaining them.

>All are outside our ability to ever perfectly understand
Yes, that is the point. Also it is why particles do not exist. This was all discovered quite a long time ago by the Greeks who dubbed it "Incommensurability" or "no common measure". You can measure it all you like, it's still fucking wrong because all you're measuring is the QUALITY of something.
