Hahahahaha 😂 pigs 🐖 might fly

Including the pen of science and ideas can be damaged by all countries of the year through publication

No the pen just flies to me when I need it

I prefer a flying carpet to escape the traffic.

Well this place is for research guys, and innovators. Not for nonsensical unworthy easy going people

Moreover non motivative stupid post graduates aren't welcome here either.

Also I am doing research on time machine again. Unfortunately I am a girl who is now into man's illusive announcement of time travel.

Some people come to this world to read newspapers only

I think it is possible. Equiping the pen with some small retractable fans and a rechargeable battery may do the trick

And how will it fight gravity?

You can benefit if you watch Boyd Bushman's videos on youtube. He has probably accomplished gravity-less movement for his employer, the airplane manufacturer Lockheed Martin. He only gives you hints how to do it, if he tells the secret he loses his head! He suggests some simple experiments one can do to beat gravity and is always doing that with the help of magnets. As he says it so well, gravity is first cousin with magnetism. If you want to beat gravity, try moving magnets in some fashion.

Thank you for the reference

Alternatively, put one on a drone.

It is probably the definition of your device (a pen) that is confusing. Be aware that many applications, called MAVs (Micro aerial vehicles), kinds of UAVs (unmanned aerial vehicles) already exist since many years and still R&D is going on. Please find enclosed such an example here: https://worldwide.espacenet.com/publicationDetails/biblio?CC=US&NR=2011278391A1&KC=A1&FT=D&ND=3&date=20111117&DB=EPODOC&locale=#

So, you are not the only one thinking of small flying devices... all the best!

Pens are the paradigm of disposable items that are lost after some use. It is not feasible to invest in flying pens.

Money comes later. The pleasure lies in the quantification. Money is piece of paper but research is priceless.

Pens with wings are easy. I am looking for a pen which can fly in vacuum at the highest speed. Can fly in air too wrt f=ma

In the vacuum everything flies. It's very difficult for us to be in the vacuum to use a pen.

Who wants to use it? I want it to fly without wings

I agree with Professor Roberto-Menadio

Roberto you have a new admirer

Well if a thing moves spirally can it fight gravity. Why are pens circular by circumference?

The way to make a pen fly in vacuum is to throw it to the earth or other gravitating object and mis. It is a well documented method given in the "Hitchhikers guide through the galaxy". It is the trajectory that you choose.

Now you can make the surface of the pen covered with solar cells and you power with that an ion gun at the back. That would allow it to make the pen have some time of powered flight.

Good luck,

I agree with Paul Gradenwitz .

Okay, start with a hollow lightweight pen-shaped object with a tiny ink reservoir at one end, and the rest of the space unused.

You finish writing your note, flick a catch on your pen, and four sprung plastic arms pop out with little rotors on. Flick a second switch and the onboard battery makes the little quadcopter rise into the air.

You'd have to be careful stowing the sprung arms and rotor blades back into the body afterwards. Flight time would probably be severely restricted, but if it's not guided, you might not want it flying for too long in case you lose it. Have the rotors slow down at the end of the flight rather then just stop, so it lands gracefully. Probably a high risk of rotor damage from collisions with walls, etc., perhaps have four or six pop-out lightweight springy wire standoffs, so that the wire makes contact with a wall before the blades, and hopefully bounces the craft away.

Oh. In vacuum. Rats :(

Rumani Dey,

The question is not as strange as it seems in the beginning. Assume you want to do measurement of some volume of space. You will need many measurement instruments that need to be brought up into space. We know the system of cube sat. Can we go further and make one cube sat to set out an armada of little pen shaped objects that become a controlled swarm? When you can make them do station keeping for some time then valuable measurements could be made.

To fall to the earth and miss is taken care of by the launch of the cube sat. Then we need only very little impulse for steering. How can we make micro rocket engines? In space most of the engines are single use.

We could make a circuit integrated on a chip with an array of pits. Each pit has two chambers isolated by a wall. They are filled with a combustible material and an oxidiser. By sending a small current through the isolation wall the heat will destroy the wall and ignite the chamber content. This results in a unit of explosion pressure in a given direction. I think a density of engine units of 100 per square mm is technically feasible. That are 10'000 pulses per square cm. The energy for one ignition can come from solar power or stored battery power. It should allow room for the scientific instruments and maybe some LED laser communication to the cube sat mother ship.

If you want to implement this don't forget to mention the source of the idea. You can ask me to help in the design.

Paul Gradenwitz
