The invention relates to use of an apparatus for solving health problems and more specifically to solving health problem caused by the lack of gravity during space habitation, travel; and radiation damage.
The human body evolved to function under earth's gravity. The cardiovascular system has evolved to push blood against gravity. Therefore, without gravity, blood is not properly distributed. For example, blood pools in the upper part of the body. Blood flow can stop, reverse and clot in the upper parts of the body. The blood accumulates in the chest and head, making swollen veins and a puffy face (fluid shift). As a result, astronauts' waistline and legs become substantially slimmer. Butt and legs also become hypersensitive to touch. Since the heart does not have to work hard in the absence of gravity, the body eventually compensates by weakening the heart muscles. Another potential ill effect of low gravity is the make-up of gut bacteria changes which could have adverse effects on immune system health.
Astronauts go into space orbiting the earth at high speed. Centrifugal force from rotation around the earth balances the gravitational pull of the earth keeping the space craft in orbit. The gravity induced free fall to earth balanced by the centrifugal force of being in orbit makes astronauts weightless in the space. This weightlessness is called microgravity. For example, the International Space Station (ISS) orbits around the earth at about 17,000 mph at 254 miles above earth. The astronauts aboard the ISS live in a constant microgravity environment. Astronauts on the ISS experience several debilitating effects caused by living in microgravity for several months.
Microgravity causes astronauts to suffer from any combination of, or all the following adverse effects:
Loss of bone and muscle mass of about 1% per month.
Far more increase of calcium in their urine than on the earth (indicating bone loss).
Atrophy of muscles (calf, quadriceps, back, neck), which maintain a balanced upright posture.
Fat accumulation and tendonitis.
Back ache caused by separation of Vertebrae by about 2 inches and weakening of back muscles.
Risk of high blood pressure
Thickening and stiffening of blood vessel walls, increasing cardiac stroke volume, which may predispose astronauts to cardiovascular disease.
Visual impairment and increase of pressure in their brains.
Narrowing of the grooves at the top of the brain (central sulcus)
Shifting of the brain upwards in the skull.
Deterioration of organ function and cardiac arrhythmia.
Changes in immune system including impaired T-cells.
Blood flow stops, even reverses and/or blood clots form in the upper part of the body
A counter measure to the negative health effects of microgravity is a minimum of two hours of exercise every day. The two-hour exercise regimen constitutes a combination of bicycling, restrained treadmill running and vacuum generated isometric exercises (weight-lifting machine strapped to the wall). Even with two hours of exercise each day, astronauts still lose bone and muscle density of approximately 1% per month plus the other deleterious health effects mentioned above. More particularly, blood flow is reduced to the arms and legs. Bodily fluid shifts to upper part of the body causing vision problems. These are all due to a microgravity environment.
Approximately 300 entities including private companies and Government agencies around the world are making space travel a priority. Their goal is to move to deep space, with permanent lunar stations, Mars colonies, space tourism and space hotels.
For example, NASA announced the commercial use of space and thirty-day trips into space for private astronauts and private tourism aboard ISS. The founder of Blue Origin, Jeff Bezos, is ambitious to build a space colony to which earth's polluting industries can be moved so the earth can become environmentally clean. That endeavor alone will require a large human workforce to live in a microgravity environment for extended periods of time. Morgan Stanley estimates space travel will grow into an industry worth more than $1.1 trillion by 2040.
One example is the long talked about trip to Mars. After about nine months travelling to Mars, people will experience all the deleterious health effects caused by living in microgravity. Another example is the colonization of Mars or the Moon. In either case, human space colonizers will live in a hypo-gravity (reduced gravity) environment for a long time. Mars has about ⅓rd of earth's gravity, and the Moon ⅙th the gravity found on earth. Longer stays in hypo-gravity and microgravity due to space travel and exploration requires improved exercise techniques. One such idea is to utilize a swimming chamber.
Long periods in microgravity without a shower is an uncomfortable reality for astronauts. With extended periods of isolation in microgravity astronauts may develop psychological problems as well. Therefore, what is needed is an apparatus that addresses issues caused by microgravity through means of entertainment and exercise.
Galactic Cosmic Rays (GCR) and solar radiation including solar flares (all together referred as “radiation”) have very high energy ions from hydrogen to iron ions. They are dangerous to any living cells in humans, plants or animals. There have been various attempts to shield astronauts from the radiation using various means, including magnets. But there has been no successful technique to do so; because active magnetic shields contain excessive mass and astronauts using them are exposed to high magnetic fields.
The invention includes an apparatus that addresses issues caused by gravity changes through means of exercise and radiation protection in an enclosure. In accordance with various aspects and embodiments of the invention, disclosed are various aspects and embodiments of Artificial Gravity (AG) exercise apparatus to combat the physical, and emotional effects of the lack of gravity; and two embodiments providing radiation protection in space. The various embodiments are apparatus that use:
AG generated using differential pressure;
AG generated using a magnetic field;
A toroid swimming pool with AG generated using differential pressure with fluid;
A toroid swimming pool with AG generated using differential pressure with fluid and a magnetic field;
AG toroid running track without fluid and using a magnetic field;
AG treadmill using a magnetic field.
Magnetic enclosure with soft magnetic material suit to shield from radiation.
Radiation Shield for spaces.
The invention is described in accordance with various aspects and embodiments in the following description with reference to the figures (FIG.), in which like numbers represent the same or similar elements.
Reference throughout this specification to “one embodiment,” “an embodiment,” or similar language means that a particular feature, structure, or characteristic described in connection with the various aspects and embodiments are included in at least one embodiment of the invention. Thus, appearances of the phrases “in one embodiment,” “in an embodiment,” “in certain embodiments,” and similar language throughout this specification refer to the various aspects and embodiments of the invention. It is noted that, as used in this description, the singular forms “a,” “an” and “the” include plural referents, unless the context clearly dictates otherwise.
The described features, structures, or characteristics of the invention may be combined in any suitable manner in accordance with the aspects and one or more embodiments of the invention. In the following description, numerous specific details are recited to provide an understanding of various embodiments of the invention. One skilled in the relevant art will recognize, however, that the invention may be practiced without one or more of the specific details, or with other methods, components, materials, and so forth. In other instances, well-known structures, materials, or operations are not shown or described in detail to avoid obscuring the aspects of the invention.
Artificial Gravity (AG) using differential pressure: Swimming may help to reduce the deleterious effects of microgravity and psychological isolation stress by providing another means of exercise and entertainment. But in microgravity fluid will float. Therefore, a swimming pool in microgravity must be pressurized above the ambient pressure to hold the fluid in its place. To pressurize the fluid, the fluid must be enclosed.
Because of microgravity the buoyancy of fluid disappears. Therefore, in microgravity, there will not be a buoyancy force pushing the body upwards nor will the body sink in the fluid due to gravity. In microgravity there is no up and no down. But you could swim in fluid in the direction one propels him/herself. However, directional flow of liquid can break the symmetry in fluid in microgravity.
The liquid resistance of fluid increases as one swims faster. On the earth if you lift your hands, you are lifting your arms against gravity. But in microgravity there is no force of gravity acting on the body. While swimming in microgravity, the swimmer lifts her/his hands against the friction (viscosity) of the fluid and splashes against the cohesive force of fluid. The faster a swimmer swims, the larger the frictional force he/she creates.
For a human 6 feet tall, 2 feet wide and 5 inches deep, weighing 170 lbs. the surface area of the person swimming (in supine position) is about 1500 to 3000 square inches. The gravitational force acting on the body=170 lb*32.2 ft/sec2=65688 lb·in/sec2.
Therefore, gravitational pressure, the force pulling downward per square inch of body area, pound per square inch (psi) on the body:
=65688 lb·in/sec2* 1/2000 in2=33 lb./in. sec2.1/32.2 ft/sec2 1 lb/12 inch2=0.1 psi, considering the person is sleeping, supine or swimming. This is less than 1 psi pressure on the earth.
Therefore, applying 2 psi of dynamic pressure above the ambient pressure in the enclosed pool in microgravity, the total pushing force on the body will be more than the gravitational pressure on the body on earth. Two psi dynamic pressure in the endless swimming pool can be maintained without danger in an ordinary pressure vessel. A garden hose on earth holds about 80 psi of water pressure. The person swimming in a 2-psi dynamic pressurized endless swimming pool will have the full gravitational effect that a person experiences on earth.
The viscosity of the fluid (water or other highly viscous fluid) will act against the muscles and joints while the person is swimming. Joints working under force will reduce tendonitis issues. The stronger the movement of feet and arms against the liquid, the more the activation of muscles, bones, and joints. The blood rushes to the active muscles. Since all the muscles will be active during swimming in water or other viscous liquid under dynamic pressure, the blood will rush to all the muscles thereby minimizing the fluid shift due to the microgravity environment. Swimming in pressurized fluid will strengthen muscles, bones and joints while minimizing the body's fluid shift experienced in microgravity. Swimming in the pressurized swimming pool in the International Space Station (ISS) (or other space environment) will use every part of the body against pressure or viscous force as if the swimmer were swimming on earth. This will reduce fluid shift in the human body and other deleterious health effects of microgravity and provide all the advantages of swimming on earth, including proper blood flow to organs, muscles, and bones.

The swimming chamber will be pressure controlled at the desired pressure to simulate earth's gravity or any other desired pressure by the controlled flow of the pressurized fluid from the input channels 106 to the outflow channels 108. While in the swimming chamber, a swimmer 102 with a breathing device 104 will be swimming within a pressurized fluid 100, with dynamic pressure on his/her body. Replacement of gravity by applied pressure and swimming against the viscosity of the fluid 100 will minimize muscle loss, bone loss and fluid shift. In other words, the deleterious effects of microgravity will be significantly minimized.
Because of the limitation of space inside the spacecraft, forward or horizontal, swimming must be balanced by an opposing flow 106 to 108 of fluid 100 to make the swimmer 102 stationary with respect to the vessel containing the fluid 100.

The directional pressure 302 can be maintained by a circulating pump 308 creating a flow of fluid to produce the desired differential pressure. The fluid pressure can be distributed evenly with the help of a perforated lid or pressure actuator. The fluid pressure can be constant pressure or a continuous flow of fluid to create the pressure gradient. If a continuous pressure gradient is desired, the fluid could be continuously circulated through a pump to maintain the desired differential pressure.

The magnetic field calculations can be done by magnetic modeling simulation. To illustrate the principle, assumptions based on the principles of Physics are used to understand the concept and its applicability. Let us consider the swimming astronaut in a permalloy deposited complete body swimsuit is a rectangular box with sides L, W, and perm-alloy deposited thickness dw. Volume v for permalloy, V=L·W·dw. Consider a deposited perm-alloy thickness of, dw=100μ=10−4 m.
The magnetic field H inside the toroid is inhomogeneous (unlike a solenoid). The permalloy shell on the box will experience a force inside the toroid towards the radial direction or any direction where there is inhomogeneous field B=μH, μ is relative permeability for permalloy
If F is the force acting on permalloy coated box, based on principles of Physics
Force F∞v, volume of permalloy, so long as permalloy is in the linear range (did not saturate or not more extra volume of permalloy)

F=1/μ0·v·Bz·dBz/dr Newton
Comparing the above formula with a numerical calculation of an iron cylinder at the end of a solenoid (where field is inhomogeneous). That checks out within a factor of 1.5. Therefore, we will calculate force on the permalloy box shell using this formula to understand the effect:

z=μrμ0 NI/2πr For a Toroid
Size of toroid is limited by the rocket faring size. The Starship fairing diameter is 30′.
For example, consider a toroid, parameters consistent with
a=6′
b=10′
This force formula will give an idea and feasibility of artificial gravity creation in a toroidal swimming pool. For a toroid:
a=6′
b=10′
1000 turns wound with 15-gauge copper wire flowing 1 Amps current the force on the box L=4′=1.21 m, W=1′=0.31 m, skin thickness of permalloy dw=10−4 m, are as follows:
At r=a=6′=1.83 m, the innermost radius of the toroid.
F=31 Newton, equivalent to gravity force acting on mass 3.2 kg on the Earth
At r=8′=2.44 m, the central radius
F=13.8 Newton, equivalent to gravity force acting on mass 1.41 kg
At r=b=10′=3.1 m, at the outermost radius of the toroid
F=9.9 Newton, equivalent to gravity force acting on mass 1 kg
If we use 15-gauge wire for winding. Wire diameter=0.072″
Will take space for 1000 turns=72″/12=6′. i.e., inner radius=6′ will accommodate 1000 turns in one-layer winding of the toroid.
Therefore, for the toroid: a=6′ and b=10′ The force acting on a box with permalloy shell (permalloy plating thickness on the swimsuit) 100μ=10−4 m around the box 4′ long and 1′ wide (representation of human) changes from 3 kg mass weight to 1 kg mass weight equivalent on the earth. This is 3 times force variation from innermost radius to outermost radius of the toroid.
Since there is no buoyancy in microgravity, the astronauts will feel the lightest AG effect at the outermost radius and strongest AG effect will be felt at the innermost radius of the toroid shaped swimming chamber. That means, the astronauts in the innermost radius of the toroid will have to swim harder to move to the outermost radius of the toroid.
Using a 15-gauge wire for winding to carry 1 Amp current and 1000 turn to generate about a 1 Tesla field inside permalloy shell (outside permalloy but inside the toroid about 1×10−4 Tesla). The high permeability permalloy or any other soft magnetic material which does not saturate. If it saturates, reducing the current in the toroid to make the suit unsaturated will completely shield the human from any stray magnetic field outside the suit. If the magnetic field outside permalloy suit is much higher causing the permalloy suit to be saturated, there can be another magnetic shield outside the permalloy suit made of higher saturation magnetization material that barely saturates from the current in the coil. Thus, the leaked field from the barely saturated outer shield is just enough not to saturate the permalloy suit. If needed, there can be multilayer soft magnetic shields of different successive saturation levels outside the permalloy suit that keeps the permalloy suit unsaturated and acts like a magnetic shield. This duel (or multilayer) magnetic shield will protect the astronaut fully from the magnetic field in the toroid, while the suit combination will allow the swimmer to experience an artificial gravity force.
Resistance of 15-gauge wire=6.56 Ω/km
Weight of wire=0.0157 lb./ft or 0.0234 kg/m
The radius of toroid tube=2′=0.61 m
Circumference of the toroid=2πr=11.5m, central r=6′=1.83m
Circumference of 1 turn around the tube=2π×0.61m=3.833m
Total length of the wire used=3.833×1000=3833m
Total Weight of wire windings=3833m×0.0234 kg/m=90 kg
Total Resistance of wire used=6.56 Ω/km×3.833 km=25Ω
Power dissipated in the windings=12×25=25 watts
If necessary, use water jacket around wire windings as heat exchanger, which can be fed back into the toroidal pool to keep the water warm.
Central circumference of the toroidal tube=2π·8′=50′=15.3 m
Volume of water in the toroid=π·0.6120.15.3 cubic m=17.9 m3
1 m3=103 liter
Consider Volume of water in the toroid=20,000 liter
Weight of water in the toroid=20,000 kg=20 tons
NASA is building Gateway in the cislunar orbit.
This water can be acquired from frozen water ice on the Moon to the Gateway.
Because the Moon's gravity is ⅙th that of earth gravity, it will be much easier to lift water from the Moon than from the Earth.
This illustration shows that the toroidal swimming pool concept with astronauts wearing a permalloy deposited swimsuit can create artificial gravity using a magnetic field generated in the toroid.
Alternatively, the artificial gravity by toroidal field can also be created without water in the toroid. If lifting 20 tons of water from the earth or the moon is not practical, a toroidal running track can be made without water in it.

At r=a=6′, the foot of the runner, there will be maximum force pulling the feet down and the force will decrease towards the head of the jogger. The current in the wire coil 608, number of turns in the coil 608 and active permalloy volume (experiencing the force from the magnetic field) can be adjusted to create appropriate artificial gravity. For a=6′ toroidal rectangular running track, the circumference of the toroid is about 38 feet. That means, the jogger 604 will run around the inner circumference 606 of the toroid running track 600 at about a degree or rotation per six inches of running. This may make the runner dizzy. For the runner to feel comfortable, the inner diameter of the toroid must be increased, which may become larger than the faring of the spacecraft.
If we use Bigelow expandable habitat (BEAM: https://www.space.com/19297-inflatable-space-stations-bigelow-aerospace-infographic.html) that can expand to a maximum diameter of 60 feet then we can make a toroidal running tack length=πd=π·60·189′.
Since the runner 602 with permalloy suit 604 will cover about 6 inches per degree of rotation. This will reduce dizziness while running on the circular track. For entertainment, the walls of the track may have a continuous moving display as if the person is running in a specific city or in natural on earth. That will be entertaining and less stressful for the runner. Since the runner may use Virtual Reality goggles 610 and can experience entertainment while running, he/she may feel less isolated in lonely environment of space.

These AG creating techniques can also be used on earth for improving sports stamina, sports training, exercise for handicapped individuals, recreation, and many other applications.
To illustrate the partial toroidal running treadmill 700, Consider the treadmill is shaped like an upward bowed walk bridge over a creek. A walk bridge has walls on both sides and a ceiling on the top. This makes a tunnel over the upward bowed (convex) walking bridge. The walk bridge, partial toroidal, tunnel is wound with wire 706 to create a toroid magnetic field within the partial toroid 700. The sidewalls of the walk bridge have a movie running, simulating any crowded street (or any other scene) of a city on the earth (earth simulation through VR). The treadmill running surface is made of stripes on rollers 708. When the runner 704 lifts the knee and pounds on the stripes with his/her heel at an angle, the stripes move backward with the impact of the heel giving a sense of moving forward (similar to a treadmill exercise machine on earth) while the person is stationary with respect to the walls. The movie running on the walls or in VR goggles gives a feeling of running in a crowded place or VR simulation with a desired companion on the earth.
The partial toroidal running treadmill enclosure should be curved upward (convex) (opposite the curvature of Woodway™ or Truerunner™ treadmill, which are concave). The treadmill 708 will be curved, like part of a toroid. In contrast, a straight treadmill (solenoid winding) would produce a homogeneous field, but a partial toroid shaped treadmill produces an inhomogeneous magnetic field. An inhomogeneous magnetic field is required for a gravity-like force to act upon a runner in a permalloy suit.

If permalloy gets saturated with higher magnetic fields required for the desired artificial gravity, there can be another garment containing a higher concentration of permalloy or other soft magnetic material 900 worn on the outside of the permalloy suit. The outer magnetic garment would not become completely saturated by magnetic fields generated by the exercise apparatuses shown in
Successive layers of garments composed of permalloy of other soft magnetic material 900 can be worn by astronauts to protect them from harmful, strong magnetic fields. This double (or multilayer) shield may create sufficient artificial gravity force while also shielding the human from exposure to harmful magnetic fields.
Another embodiment of a soft magnetic material 900 suit is to create a weightless situation under the earth's gravity. NASA's Neutral Buoyancy Lab (NBL) is large, 10 Olympic swimming pool combined. NBL offers the best available analog to working in space. NASA spends multimillion dollars a year to maintain it. Using a permalloy suit will create a better analog of working in space than NBL. Astronauts practice EVA in NBL. But that is in water and viscosity of water will interfere with free space activity. But permalloy (or soft magnetic material) suit will create the best condition of microgravity in free space. For that, consider a ceiling made of a magnet (or electromagnet). A person in permalloy suit will be attracted to the ceiling. Now adjust the magnetic force pulling up to the ceiling equal to the gravity force down. That balance of force will create weightlessness of free space. If needed, there can be another electromagnet on the floor (that may repel a magnet if attached to the feet). The ceiling and the floor electromagnets can be adjusted to get a desired band of neutral, gravity free zone. This weightlessness will be very attractive for recreation on the earth to simulate the microgravity of space on the earth. Presently, a very expensive technique of parabolic flight (vomit comet) or jet is used to create weightlessness only for 20 seconds without going to space. https://www.gozerog.com/charges over $5000 per person for recreation.
Another embodiment of permalloy suit will be to divert the charged particles from the solar radiation and Galactic Cosmic Rays (GCR) entering the enclosure during space travel. Radiation is a serious problem during space travel or on Moon or on Mars.
If we have an enclosure (cubical) with ceiling and floor made of magnets (or electromagnets): South-North-South-North polarity (or magnetic material cylinders, or any other shape, and wire wound around the outer magnetic cylinder to fully magnetize the walls of cylinder), the person in that enclosure wearing a permalloy suit will be protected from damaging charged energetic particle radiation; because of diversion of charged particles by a magnetic field in the magnetic enclosure. Further, the charged particles outside the cylinder will not penetrate inside the suit because of 104 times (than outside the suit) higher magnetic field within the permalloy suit due to high permeability (104) of permalloy. Human cells will be protected from the damaging radiation, which will be shielded by the magnetic field inside the magnetic permeable suit. Since the magnetic field will permeate only inside the permalloy suit, the human tissues will not experience the magnetic field from the magnet (stray field) when the permalloy suit is not saturated. If a stronger magnetic field is required to divert the energetic charged particles and if permalloy gets saturated with that higher field, there can be another enclosure of higher saturation magnetization outside the permalloy suit in the magnetic field that the outer enclosure of the suit does not saturate. This higher saturation magnetization may be cylindrical (or any other desired shape, including another layer on the suit). The high saturation magnetization material outside the permalloy suit will be the major shield, reducing the magnetic field on the permalloy suit below the saturation of permalloy. This double (or multiple) shielding will protect astronauts from the damaging radiation and stray magnetic fields by shielding magnetic fields and charged particles through unsaturated permalloy and protecting the human from the magnetic field and radiation damage.

Wire 1010 is wound around a toroid 1000 made of magnetic material 1012. For example, consider 1012 as steel, which saturates around 2 Tesla. Magnetic field B, 1011, located within the thickness of the toroidal magnetic shell 1012 (made of steel or other magnetic material) will be about 2 Tesla. The toroid 1000 fits in the fairing of the spacecraft. Some of the magnetic field, H 1002, leaks inside the living space when a magnetic field generated by the coil is above saturation of the magnetic toroidal shell 1012. The leaked field is just enough to saturate a permalloy (or multilayer permalloy) sleeping bag or suit 1008 that an astronaut 1004 is wearing. This arrangement will shield the astronaut from radiation, stray magnetic fields, and provide artificial gravity.

This is 3 times force variation from innermost radius to outermost radius of the toroid.
