Abstract

A set of Gravity Power Towers with built in intelligence and connected with each other with a transport guide ways or path ways for the mass to be transported on wheels, form the transport network for transporting people and cargo point to point, powered by gravity. A Gravity Power Tower is a gravity based embodiment for storing substantial potential energy in a number of relatively heavy and vertically moving masses, embodied as Power Mass Modules; release the said potential energy in a controlled manner using a continuously variable intelligent gear system and high speed traveling power transmission cable; the force so applied to accelerate at a fraction of acceleration due to gravity or sustain at steady speed any rolling mass of relatively of a fraction of the size of the masses in said Power Mass module; along a generally horizontal or graded path way; and when the said rolling mass needs to come to halt, the embodiment converts the kinetic energy back to augmenting the potential energy of the vertically moving masses in the Power Mass Module; any shortfall to gain back original status of the potential energy of the masses is made up using external energy like electrical motors; thus the embodiment creates new gravity powered elevated and underground railway, gravity powered road way and gravity powered runway at airports.

Claims

1. An apparatus comprising of a set of networked Gravity Power Towers, each having a set of vertically moving extremely heavy masses called Power Masses and an intelligent variable main gear system;

the said Gravity Power Towers interconnected with one or more similar Gravity Power Towers by High Speed Power Transmission Cables, end-less, roller supported and sag-free, the said Cables having own gear systems at either Gravity Tower and the said gear system gets engaged or disengaged with the said intelligent variable main gear apparatus of the Gravity Power Tower as per direction of the intelligent microprocessor actions; and

the said High Speed Power Transmission Cables capable of gripping a rolling mass with built in microprocessors based intelligence and communicating with Gravity Power Towers;

the rolling masses running over and along transport mode pathways like existing but suitably modified rail having a hour glass shaped space frame supported on two standard rails by bogies with pair of wheels running over two rails fixed on either side of an opening at the bottom member of a rectangular box structure housing the High Speed Power Transmission cable and the bogies, road with a middle trench carrying the High Speed Power transmission cable and electromagnetic coupling capability with the road vehicle and runways having a middle of the runway a trench to house the High Speed Power transmission cable, extending from one Gravity Power Tower to another, the said pathways generally in a horizontal plane;

the said Gravity Power Towers with built in microprocessor based intelligence and inter communication among towers and rolling masses, the microprocessor intelligence controlling gear ratio and direction of the variable a gear system thus inter connecting the vertical motions of the said heavy power masses in the Gravity Power Tower and the rolling units, causing automatic transportation of rolling mass units attached to the power transmission cables traveling on the transport pathways, in such a manner that the vertically moving heavy masses called Power Masses, typically of the order of ten times that of the rolling mass unit, in the said Gravity Power Towers and the rolling mass units can run eternally, on the pathways, starting from one gravity Power Tower to stopping at another, practically almost entirely based on the gravity with the least input of external energy to cover friction losses in rolling and gears, constantly balancing the variation in potential energy of the set of masses in Gravity Power Tower with inverse variation of kinetic energy of set of the connected rolling masses, the rolling mass units drawing the needed tractive effort from the Power Masses in a controlled manner to accelerate away from a Gravity Power Tower, but the set of Power Masses gain back the lost potential energy by taking away the kinetic energy of other rolling mass units approaching the Gravity Power Tower, thus stopping the said approaching rolling mass units while raising back the said Power Masses;

the shortfall in recovering the height lost of the Power masses because of frictional losses alone needs external energy, thus converting existing rail, road or runway in to an automated, practically perpetual and self-sustained linearly oscillating Gravity Powered transportation systems, once set off with a one time initial charge of potential energy of the sets of Heavy Power Masses, thus effectively saving a major portion of currently used energy in the transportation of people and goods.

2. The apparatus comprising of a set of networked Gravity Power Towers as in claim 1, each of the Gravity Power Tower as in claim 1, comprising of a number of Power Mass Modules, each Power Mass Module having an embodiment comprising of vertically moving very heavy mass of the order of hundreds of tonnes, the said large mass dropping vertically under acceleration due to gravity in a controlled manner, known as Power mass, to engage and drive gear system of a power transmission cable, to which the said rolling mass, typically less than a hundred tonnes, is coupled and provide the traction force to move a rolling mass of size a fraction of the power mass at a fraction of acceleration due to gravity in generally horizontal or graded direction, to reach desired maximum speed, sustain the speed as needed, but recover back most of the energy by raising the Power masses, which dropped while driving some other rolling masses in another linked gravity power tower, on some other pathways, thus conserving energy needed in transporting the rolling masses, thus needing only marginal incremental input of external energy to make up merely for the energy losses of rolling friction and gear friction, forming an integrated vertically oscillating heavy masses in consonance with horizontally oscillating rolling masses, constantly matching variation in potential energy of Power Mass with inverse variation in kinetic energy of rolling mass, with microprocessor based intelligence to control the coordination, becoming a self-perpetuating system once started, needing external energy input only to make up for friction losses, which appears as a shortfall in recovery of height lost by the Power mass, practically balancing the energy spent with energy recovered over a cycle of typically 24 hours, with short term imbalance of number of rolling mass units to be driven away taking energy being more than the number of rolling units with kinetic energy arriving at the Gravity Power Tower from which the energy is to be recovered, thus the Gravity Power Tower provides enough height for additional vertical travel for the Power masses, but this typically results in the Tower height of 15 to 20 m.

3. The Gravity Power Tower as in claim 1, comprising of Power Mass Module, which stores maximum energy of gravity in the form of potential energy when the supporting cables of the heavy mass is fully wound on the roller drum mounted on a shaft with gear connections to an electric motor as also to the main gear system and to a fly wheel energy storage unit, the said storage unit activated more for secondary storage of energy received from internal momentums gained by the very heavy Power masses which need to be stopped after their gear systems are disconnected from driving a rolling mass;

this stored energy from flywheel is given back as needed, particularly when the heavy power mass at rest is given the initial upward movement, to be connected to the gear system of the power transmission cable though the main gear system, to be raised by the rolling mass moving at peak speed towards the said Gravity Power Tower;

thus to avoid shock, the energy is drawn back from the flywheel storage to start the first slow upward movement, and further the variable gear system utilised to operate at high gear ratio to minimise relative velocity at the time of interconnection, and not for driving the rolling mass, the gear connections made as needed, by the combined working of the microprocessor based intelligence in the main gear system, the gear system of the High Speed Power transmission cable and the gear system connecting the flywheel storage.

4. The Gravity Power Tower as in claim 1, comprising of Power Mass Modules, which is capable of receiving kinetic energy from a rolling mass approaching in generally at horizontal direction, at a speed and needed to stop, the kinetic energy received though a Power Transmission Cable to which the speeding rolling mass is coupled, the said Power mass in the Power mass Module either one or more than one, get engaged though the main gear system to the gear system of the Power Transmission cable, and the said power mass or masses rise vertically against gravity thus gaining back potential energy while taking away the kinetic energy of the rolling mass, to bring the said rolling mass to a halt, thus recovering most of their original energy back, earlier used to drive similar rolling mass over another pathway, the timing and process controlled by microprocessor based intelligence.

5. The Gravity Power Tower as in claim 1, comprising of Power Mass Modules, in which the said heavy power mass can drive a rolling mass unit at a constant high acceleration even at very high speeds by the use of variable gear ratio, and gravitational force, unlike in case of electric motors which get limited in power delivery at higher rotor speeds and similarly braking does not depend on the adhesion of wheel and the pathway, so deceleration at a constant high value, commensurate with human comfort is possible, while the Power Mass recovers its potential energy getting hauled up by the rolling unit approaching the said Gravity Power Tower, thus losing its own kinetic energy and coming to stop, the entire process controlled intelligently by the microprocessors in the main gear system by manipulating the variable gear ratio, such that the rolling unit comes to a stop at a predetermined location, like an access point.

6. The Gravity Power Tower as in claim 1, comprising of Power Mass Modules, the said Power Mass Module comprises of an electric motor and a flywheel energy storage both of which can act though the gear connectors to the shaft over which the cable drum of the power mass is mounted, to cause the mass to be lifted to make up for the hysteresis losses, or in a very rare case even to fully restore back the power mass to its maximum potential energy or provide the just needed upward movement of the heavy power mass, before getting connected to the speeding rolling mass unit to be stopped from peak speed.

7. The Gravity Power Tower as in claim 1, comprising of main gear system, intelligent enough to connect to one or more Power Masses, work out and set the gear ratio for providing the optimum required gravity power from one or more than one Power Mass Modules, to a Power Transmission Cable gear to serve need of a rolling mass or recover kinetic energy from a stopping rolling mass, the gear ratio is gradually adjusted to practically eliminate internal shocks to make a smooth conversion of kinetic energy of rolling mass into gain of potential energy within the Power Mass Module, thus at any instant variation of potential energy of Power Masses always equals the variation of kinetic energy of the rolling mass attached to the Power transmission cable, after accounting for the loss of energy in internal rolling friction.

8. The Gravity Power Tower as in claim 1, comprising of the Power Transmission cable, which is an embodiment of continuously looping wire rope cable typically of a diameter of 15 to 20 mm, having pulley gear at one end connected to the main gear system of the Gravity Power Tower, the said pulley gear ratio controlled by the main gear system, and at the other end a pulley or again a pulley gear depending on the said other end not connecting, in another embodiment, or connecting with another gravity tower which is normal, to loop around and follows the guide way or path way that the rolling mass is using;

the embodiment further has a double coned twin rollers, with a single flange at the thicker middle portion and the roller tapering from center to either end in a frame, the said frame of small size and the rollers traveling in the direction of motion of the cable, over twin steel rounds which are parallel to the Power Transmission Cable, the said steel rounds fixed on either side of an opening in a rectangular metal box typically of a size of 200 mm in width and 70 mm in height, and the entire frame with rollers contained in the said small metal box, with an arm from the frame extending out of the metal box though the said opening between the steel rounds, and the said arm coming out of the box firmly holding the Power Transmission cable, gives support and guidance for high speed travel, such said supporting frames occurring at intervals of typically 5 to 10 m, and all the support frames with the said special rollers, continuously travel in the metal box, and the metal box is continuous over the guide way that the Power Transmission cable serves, keeping the cable practically sag-free as well as fully guided and with low rolling friction, enabling high speed travel along with the rolling mass attached to it;

the said metal box firmly fixed with the longer side not having the opening in middle, to one of the fixed elements of guide way or path way that the Power Transmission cable has to follow, the axis of the rectangular box running at middle of the pathway parallel, located in such a manner that the set of gripping arms of the rolling mass units can access. If the rolling mass is below the Power Transmission cable, then the weight of the cable is taken by the steel rounds fixed on either side of the opening;

but in case the rolling mass is above the Power transmission cable, then additional pair of steel rounds are provided at bottom member to support the rollers of the frame and the rounds next to opening come into action when the Power Transmission cable gets coupled with the rolling mass, and cable gets lifted up, and the double coned wheel pair of the metal frame bogie, hug the steel round guides overhead.

9. The Gravity Power Tower as in claim 1, comprising of the embodiment of Power transmission cable which has a component of a set of gripping arms in scissors configuration, one end pair of which is mounted on the rolling mass permanently, and the other end pair get clamped or remain open depending on the operation of the end pair located on the rolling mass;

further the inside of the grips which clamp on the Power Transmission cable have in built rollers perpendicular to cable, so that when being clamped with progressively increasing pressure first rollers will start rolling and as pressure increases the rollers get pressed inside and the grips firmly clamp on. This is to reduce friction and heat and to account for minor relative velocities between the cable and the rolling mass. In another embodiment the grips are replaced by an electromagnet operated by the rolling mass, and the Power transmission cable carries a steel plate at every frame support so that magnetic coupling is possible.

10. The apparatus comprising of a set of networked Gravity Power Towers as in claim 1, have Gravity Power controllers, comprising of microprocessors for processing information received from the main gear system controller, Power Transmission gear controller, the controllers on Power Mass Modules, the rolling mass controllers being handled by its Power transmission Cables;

and while all most all local operational events of the tower are handled by the Main Gear System controller, the Gravity Power Controller supervises the same and also the Gravity Power Controller of the tower constantly interacts with colleague adjacent Gravity Power Controllers to know the status of arriving rolling masses and for planning and managing the energy levels to be maintained in the Power Mass Modules.

11. The apparatus comprising of a set of the networked Gravity Power Towers as in claim 1, linked with one or more than one other Gravity Power Towers, with pathways which, in one of the embodiments comprise of modified existing rail way, as a Gravity Powered Rail Module having a rectangular box enclosure made of steel or pre-stressed concrete, typically of a size of about 4 m in width and about 3 m in height in cross section, but of length equal to the route length, with a central running opening in the bottom member the opening parallel and running all along the route length, either above ground on column supports, or underground as part of a sub-way;

the said box having two standard rails fixed on either side of the central opening at a standard gage, over which standard railway bogies with steel wheel axles run;

in the present embodiment a space frame, an hour glass shaped in cross section, is placed in such a manner the top portion spans the bogies inside the said box enclosure, the narrow portion of the space frame occurring at the opening in the bottom member, with the bottom half of the space frame widening out to get firmly attached and integrated with a coach shell or a frame carrying a cargo container;

thus coach shell out side the box enclosure and the supporting space frame spanning the bogies and riding with them, are structurally integrated with improved torsional resistance in horizontal plane, without any suspenders to hold the coach shell;

the rolling mass, that is the coach with passengers or a container will not have any swing or sway even though traveling below the rail track and outside the box and below the box, as said mass is firmly part of the space frame riding over the running bogies in side the box;

the said space frame is provided with gripping arms over each of the pair of running bogies, the said gripping arms clamp on to the Power Transmission Cables which traveling in its metal box enclosure as in claim 9, fixed overhead to the ceiling, gets either accelerated or retarded depending on the High Speed power transmission cable gear systems gets engaged with one or more than one Power Mass modules in the Gravity Power Tower to gain kinetic energy or lose as in claim 3, all these actions dictated by an intelligent microprocessor based on board controller in communication with Gravity Power Tower'"'"'s microprocessor based controller;

the said space frame with it'"'"'s load will not load the High Speed power Transmission cable, but transfers the load on to the running bogies over which the space frame takes support;

but as the space frame is pulled or retarded, the pair of bogies at either end get pulled along with the space frame through a pivot connection;

thus the rolling mass in this embodiment becomes an integrated part of interacting masses within Gravity Power to become a self-sustained oscillating system taking and giving back energy whenever they travel from from one Gravity Power Tower to another but for friction losses;

the top half of space frame inside the box and spanning the two running bogies, also contain within its confines firmly fixed a fly wheel energy storage unit, the said flywheel storage is not a primary energy provider, a battery pack, compressed air tank, and a compressed cold fresh air tank;

12. The apparatus comprising of a set of networked Gravity Power Towers as in claim 1, having in one of its embodiments of rail based modified pathways connected to other Gravity Power Towers, provided with the Gravity Powered Rail Module as in claim 11, further has an embodiment of four solid rubber wheels mounted on each of the rolling bogie frames, running on the rails in the rectangular enclosure, the said rubber wheels having axes of rotation perpendicular to track and they rotate in horizontal plane;

the said rubber wheels normally do not touch the side walls though they travel very close to the side walls of the box enclosure;

the said rubber tire wheels can run against the side walls, only when so engaged to feed energy to flywheel secondary energy storage, if needed, as the coaches get launched, but the said solid rubber tires mostly idle in travel thus not contributing to loss of energy in rolling friction;

these rubber wheels do not guide the running space frame on bogies, the said bogies having standard steel wheel sets as in existing railways, guided only by rail track under, the rubber wheels having a short gap separating from the side walls of the box enclosure;

the said rubber wheels serve as emergency derailment preventing system cum brakes for the bogies by stretching out to run against the side walls when a limiting lateral acceleration value of 0.35 g is reached, the said acceleration monitored by a microprocessor unit taking input from mounted accelerometers on the space frame and running bogies;

thus the rubber tire butting laterally against the side walls will not allow the bogies to move laterally out of track;

further the said solid rubber tire wheels also serve for emergency braking, when they get pushed to bear against the side walls and disc brakes applied to stop the motion using the friction between the rubber and the concrete surfaces, thus holding back the integrated space frame and the bogies connected;

the said rubber tires when butt against the side walls, the reactions from each other get balanced in the horizontal direction, without adding to any vertical load nor any additional bending load to the space frame, which is the advantage of keeping the rubber wheels rotating around a vertical axis as compared to any other orientation of the axis of rotation;

the wheel sets do not have any brake system nor any any electrical motors and gears, thus reducing internal friction as well as unsprung mass on rails.

13. The apparatus comprising of a set of networked Gravity Power Towers as in claim 1, with modified rail based pathway comprising of the Gravity Powered Rail Module as in claim 12, can be used in different embodiments as single, double or multiple formations, when one may have a double line route or multiple line route, in such a manner that the number of rolling mass units arriving at a Gravity Power Tower will generally be the same as those which need to be dispatched;

all such modules integrated laterally with each other and supported by columns at he junctions;

typically two of the Gravity Powered Rail Modules can be laterally attached to give a double line route, with a central hollow beam between the boxes being supported on columns rising from median of any road way in a city, the said columns being of such height that the bottom of the coach clears all road based traffic and access stations located also at that high level with lifts provided on side paths for commuters to board, and typically every station of access will have a gravity Power Tower located too. If need be the gravity Powered Module could be carried as bottom member of a cable stayed bridge to cross rivers or to provide long uninterrupted spanning in a city;

the Gravity Power Towers in such cases may get located only at either end of such a bridge.

14. The apparatus comprising of a set of networked Gravity Power Towers as in claim 1, with modified rail based pathway comprising of the Gravity Powered Rail Module as in claim 12 and 13, in another embodiment, can be placed underground just below the existing road surface, the box enclosure of the module having its side walls extended below and resting and getting integrated with a bottom slab typically 7 to 8 m below ground level, providing water proof enclosure for the coach to travel under ground;

sub-way access from foot paths and lifts to give access to coaches at stations going below the road level and located at side paths provide easy access for commuters;

the Gravity Power Tower is also co-located underground to provide the gravity power and recover the power;

further the modified rail based pathway run under gravity power, can have the same gradient as the roadway, because the tractive force is not dependent on the rail-wheel adhesion, thus giving significant advantage in sub-way construction costs.

15. The apparatus comprising of a set of networked Gravity Power Towers as in claim 1, in another embodiment of their connecting pathways comprising of modified existing road lanes in the city, carry in the middle of road along the alignment, a shallow continuous trench typically of width 400 mm and depth 200 mm to accommodate the metal box enclosure of the High Speed Power Transmission Cable as in claim 8 and 9;

the said High Speed Power Transmission cables having firmly attached steel plates above the cable closer to road surface and parallel to road surface at every location of the frames having the pair of double coned single flange wheels running in the supporting and guiding metal enclosure, as in claim 8 and 9, the said trench top covered by a non-magnetic material without touching the traveling steel plates of the High Speed Power Transmission Cable;

the said steel plates firmly attached to the High Speed Power transmission cable being capable of getting coupled with an electro-magnetic matching steel plate element of a road vehicle;

the electro-magnetic steel plate, typically of 300 mm×

300 mm size, fitted at the bottom of a road vehicle on an extended arm in the front such that the the said plate faces the road surface and travels close to the trench top but not touching the road surface, in the middle of the said modified road lane;

the electromagnetic steel plate on the road vehicle gets magnetised at the throw of a switch from the driver of the road vehicle, which then magnetically gets coupled to the High Speed Power Transmission cable traveling unseen in the trench below the road surface at specified speed for the lane;

different lanes having different prescribed speeds of traveling High Speed Power Transmission cables;

thus providing the tractive force to the road vehicle from the Power Masses of the Gravity Power Towers for steady movement or even acceleration or deceleration for all the vehicles in the road lane so attached to the Power transmission cable;

the mass of the road vehicles so attached form the rolling mass units acting in consonance with the Power Masses to create a linearly oscillating system where in partially energy given for driving is recovered back while stopping the road vehicles by the Power masses after accounting for the friction losses. Existing electric powered road vehicle is expected to be modified by providing the Gripping arm with electro magnetic coupling plates, which allows the road vehicle to draw motive force from the Gravity Powered Road lane for moving at different speeds by changing the lanes, as well as charge their battery packs using the Gravity Powered Road. On the same High Speed Power Transmission Cable many road vehicles per a lane get attached drawing tractive effort. In another embodiment, the Power transmission cable carrying multiple road vehicles in a city can be interlinked with road signals, so that the column of vehicles are automatically brought to halt, while recovering their kinetic energy back as gain potential energy of the Power Masses. In another embodiment, intercity highway lanes can be similarly Gravity Powered with Gravity Power Towers located typically every kilometer or half a kilometer, convening existing road lanes into Gravity Powered Roads, even to power trucks but rail based modified pathways will prove to be more efficient in energy saving because of low friction losses. Green gas emissions get controlled substantially in Gravity Powered Roads, removing all the internal combustion engines for very long haul cases too for passenger cars, making electric cars viable.

16. The apparatus comprising of a set of networked Gravity Power Towers as in claim 1, in another embodiment of their connecting pathways for air traffic, comprises of existing runways duly modified to place the High Speed Power transmission cables, either one or two, in the central region and along the runway alignment of the modified runway all along, in a hidden trench as in claim 15;

and the Power Mass modules at Gravity Power Towers at both the ends interconnected by the runway may be engaged for providing the hauling force to make an aircraft reach take off speed;

the said hauling force is applied though traveling steel pates attached to the High Speed Power Transmission Cable, get engaged magnetically with an electromagnetic matching sets of plates on the aircraft landing and take off gear equipped with an electromagnetic grip and activated as in claim 15, or in alternative embodiment, a slit running along the center line of runway could provide a wire rope based grip as in claim 9, to make the air craft reach take off speeds of 200 knots from whence the air craft engines can take over. Similarly while landing the air craft could engage with Power Transmission cables in similar fashion as afore mentioned, and recover the kinetic energy of the air craft to recoup energy of the Power Mass Modules in the Gravity tower. Thus the aircrafts taking off and other aircrafts landing at an airstrip pathway linking two Gravity Power Towers can form a self perpetuating oscillating system where in energy is taken from the Power masses while taking off, but recovered back while landing of another aircraft, except for friction losses, thus creating Gravity Powered runways. The fuel consumption at take off stage is significant and this saving coupled with energy recovery from landing aircraft, can substantially help conserve fossil fuel.
