When doing one of my papers for school on why people should support space exploration, and how to make it safer for humans I was brought to the notion of artificial gravity. This is basically utilization of other forces like work, electromagnetic radiation, kinetic energy, and other types of forces to mimic the forces of gravity. One of these types of forces that is perceived to create a force similar to gravity is centrifugal force. NASA has already been able to create artificial gravity by using a centrifuge and it working towards understanding how it will effect people using it. However their way of doing it is different that my idea for it. Their idea is that the space ship itself adds a rotation to a certain velocity and by utilizing that the centrifugal force creates gravity.
However I was wondering if this centrifugal force could be possible by an interior rotating chamber for sleeping and such or just and interior rotating interior of the ship. I figured that if it is the interior of the ship it will cause less trouble with it's overall velocity being transferred into the rotation used for generating an artificial gravity. However I would like to focus on the sleeping chamber.
The sleeping chamber approach seems to be an idea that astronauts would go and sleep in a room which produces gravity and could work in zero gravity. So in my idea is that there be a room which has a cylindrical shape and there be beds attached to this cylinder evenly placed around which each astronaut or person could rest in. This room has two cylindrical parts of focus the outer cylinder connected to the rest of the ship so that the outside of the spacecraft is able to connect to the rest of the ship or space station.Then there is the interior area where the beds are attached onto the cylinder's interior cylindrical surface.These beds contain straps which keep them from being flung out of the beds when the room rotates if that is logical. And the interior cylinder is held in place by the connecting area having a lip that secures that the cylinder won't go out of control.
The interior cylinder is rotate through mechanical or electrical power means to a speed to where it can get the centrifugal force up to the value of one G. That of course means that we will have a fast rotating cylinder inside of the spaceship (space station) which if it got messed up it could cause all sorts of problem. I think it may need to be initiated prior to take off on a spaceship and if in a space station I think that it would have to have a way to keep the interior cylinder from moving around. Though I think that if it is able stay together it may work but at the cost of lots of money. Which is because the radius of this cylindrical chamber is in my thoughts to be about 6 feet and since the radius relates to the force of rotation needed to create a centrifugal force similar to earths gravity. And instead of it being able to work for standing it most likely would only work for a sleeping chamber.
I would like any input on this idea. Though I didn't think about how this interior rotating chamber would effect the rest of the ship I would be interested in any and all thoughts concerning this idea and whether it could be a feasible resolution to creating artificial gravity for astronauts to help with bone growth and more. Since gravity causes all sorts of problems. Also I came up with some of my ideas while reading from the cite below from NASA about them trying out their two subject centrifuges. I am studying about physics so this was about gravity it was very interesting and it would help a lot in my researching of physics.

Dear Jonathan
the NASA test the "centrifugal" test is not "gravity" The high rotation of object is creating centrifugal force due to mass of oxygen in the room, e.g. when you riding a motorcycle in windy day, it is mass of oxygen is push you back. Unfortunately in last three centuries we think it is gravity. this perception is wrong. But to answer your question for astronauts in space, it could be done by duality of two different rotation of opposite direction. this test has been done, and I believe it worked.
Article Quantum Mechanics Gravity, Mechanical Gravity of Newton is Myth
this article of mine has been presented in Osaka=Japan last moth.
Centrifugal rotation (and any rotation) is not gravitational action. Rotation of the body is directed oppositely to Newtonian gravitation. Astronaut flying in the gravitational field of the Earth is in the state of weightlessness because the action of gravitational field of the Earth is balanced with the action of the field of rotation of cosmic satellite: GM/r^2 = v^2/c^2, where v is the velocity of orbital rotation. Astronaut can as be sleeping and not sleeping in this state. If the centrifugal rotation will be added cosmonaut will feel this action but this effect is not linked immediately with the state of sleeping person. Rotating astronaut can either sleep or wakefulness independent on rotation. I think, the strong rotation can disturbe the state of sleeping. The same situation will be realized in the Solar system as the part of Galaxy. Because the Sun flies together with the Earth in Galaxy with the velocity 250 km/sec, just this velocity is a limit for cosmic travels in Galaxy: this is the diapason of gravitational safety. Cosmic apparatus must not overcome this value of velocity. We are children of Galaxy, consequently we must take into account its laws. That to fly to stars we must begin consider us in the form of cosmic persons which possess not only material but energetic body. If we allow the think that momentary transfer of energy is possible we will be understand that the stars are more near than we think until.
??. What I mean in general is if there is away to apply a force equal to gravity's force not meaning we create a gravitational force but a force that acts like gravity causing objects with mass to fall towards the rotating cylindrical body so to lessen the decay of the astronauts physiology do to the lack of gravity. I was just trying to come up with a possible solution to that problem. Thus this force is artificial since it is not gravitational force but centrifugal force. And I was wondering whether it was possible for it help in any way. Though I do not know how the force causing the cylinder to rotate will effect the inhabitant of the room I know that by using centrifugal force there is a possible way to mimic gravitational force for things inside it's radius. I hope this makes my question clearer.
Yes, this would work fine. It would be best If the rotating enclosure was somewhat cylindrical but necessarily circular, and that there was no close-by gravitational force. In effect you would be sleeping and walking, and your habitat would be on the cylindrical walls. The rotation rate would depend of the object's size and cylindrical diameter whereby the rotation velocity would produce a centrifugal outward force of about 1 G on the inhabitants.
Dear Jacinto, There is still technically a gravitational field at work within the cylindrical area however the gravitational force is significantly weaker in comparison to the Earth's gravitational force which is what keeps our bodies on Earth and allows them to function as they do on Earth. As for the effect of objects in the center of rotation. I am not sure other than that the centrifugal force causes the objects affected by the circular motion environment created by the occillation of a circular body to be pulled away from the center of rotation. meaning that if one was standing such that the force was directed so that it push a person's body in an upright position toward their feet it can potentially mimic the nature of gravity which keeps us from floating off into space. As for the objects inside the center of rotation I am not sure how they will be effected since the effect is determined by velocity and distance from the center of occillation. I think.

The notion of constructing part of a vessel to include a rotating section is not new, but it *is* a good idea.
At one extreme, one could have the habitation 'pod' of a vessel joined to some equally massive part of the ship by tethers - spin the pair around a common axis, and your crew will be as happy as proverbial clams.
A rotating cylindrical section was common enough as a trope in the late 60s for it to make its way into the design of Clarke/Kubricks's 2001 on the Discovery.
I'd guess that the NASA TRS will have some studies from that period.

Rotation of the room, where astronaut is, acts as additional gravitational force of non-Newtonian kind. This force is created by the field of non-holonomity. In terms of General Relativity it means that 3-space (spatial section of space-time) is inclined to lines of time. The value of the angle between the temporal coordinate x^0 = ct and spatial coordinates x^i (i = 1,2,3) depends on the velocity of rotation of 3-pace. The more is rotational velocity the more is the angle between the time and the space. The time "falls" to the 3-spae if the space rotates with the light velocity. It means that the space and the time are the same in this case. It is evidently that the real observer cannot exist in this conditions as a physical body, because the maximal velocity of rotation of the Earth is 500 m/sec. The direction of rotation acts on the temp of the observed time. This result was obtained by Hafele and Keating in 1970-s. The scientists research dates of 2 clocks where one clock is rested at the surface of the Earth and other flies at the airplane along equator too different directions. It was obtained that dates between motions in direction of axial rotation of the Earth and against it differ to 208 ns. The positive correction takes a [ace if airplane flies in the direction of axial rotation. It follws from the theory of physical observed values of Zelmanov that the temp of the observed time tau depends from 2 factors: gravitation and rotation of reference system: dtau = [1 - (w + v^2/c^2)]dt, where t is ideal time: t = x^0/c. Because gravitational field is very weak in cosmic space and velocity of rotation v

Good luck!
If your room was 10m radius, it would need to rotate at 10 rpm to get 1g artificial gravity. Try that on a playground roundabout for 10 minutes then try to walk in a straight line when you get off. To reduce that to 1 rpm needs the bed to be 1000m from the axis and even that might be uncomfortable.
Rotating the whole station needs no extra equipment, stabilises its axis and allows much larger radii to be used. The classic example is from the film 2001.
Rotation of the room creates energy of another kind than Newtonian gravitation. This energy acts to temp of the time of cosmonaut. The interval of the observed time is: d/tau = (1 - w/c^2 - v_iu^i/c^2)dt, where w is gravitational potential, v_i = -cg_0i/(g_00)^1/2 is the velocity of rotation, u^i is the velocity of motion, t is the coordinate (ideal) time, i = 1,2,3. Neglecting w, we obtain that the temp of the time for observer (cosmonaut), we find that the temp of tau depends only of product of rotational and velocity of motion . In principle, the temp of time for cosmonaut depends from the both factors (motion and rotation). The temp of the observed time decreases from the rotation and it can be stopped by v_iu^i = c^2. But how is it possible to reach such conditions? Can the cosmonaut live in these conditions as physical body?
Dear Jonathan Zane Peters ,
everything is beautifully explained here:

The state of sleeping depends on the state of surrounding gravitational field, which depends on the rotation and gravitation of attraction. Any human can sleep only by the condition that activity of brain corresponds to energetic state of surrounding space. If this corrspondence absents, he cannot to be sleeping. May be it is possible to find the condition of the correspondence, but they are strongly individual for every human.
Important addition: the velocity of rotation cannot be more than 250 km/sec --- diapason of gravitational safety. This is the velocity of the Earth in Local Group of stars. Humanity body can transform to another form, i.e. he does not possess our usual body. It is possible, the body will destroy. Our contemporary bodies can exist in determined diapason of energies. Remember: we rotate around of the Earth's axis with the maximal velocity 500 m/sec and around the Sun with 30 km/sec. Local Group of star is our stellar Home which safeties us from action of surrounding galactic space. Our state of sleeping depends on energetic state our orbit in Local Group.
