An apparatus and method of using compressed air to move fluid thereby creating a gravity differential of suspended fluid tanks. The apparatus comprises a first tank, a second tank, a glide track, a glide car, an air compressor, a diaphragm pump, an air storage vessel, and a brake system. Fluid is pumped from one tank to the other tank, thus causing the two tanks to rise and lower accordingly. The rotational force and associated rotational spin associated with the raising and lowering of the tanks may be harnessed.

An energy storage and delivery system includes an elevator, where the elevator is operable to move one or more blocks from a lower elevation to a higher elevation to store energy (e.g., via the potential energy of the block in the higher elevation) and operable to move one or more blocks from a higher elevation to a lower elevation (e.g., by gravity) to generate electricity (e.g., via the kinetic energy of the block when moved to the lower elevation). The energy storage system can, for example, store electricity generated from solar power as potential energy in the stacked blocks during daytime hours when solar power is available, and can convert the potential energy in the stacked blocks into electricity during nighttime hours when solar energy is not available, and deliver the converted electricity to the electrical grid.

A mechanism to create rotational mechanical advantage from an acceleration field consisting of a gravity arm assembly (14) rotationally connected in a horizontal plane to a gimbal assembly (41). A powered action arm assembly (21) rotationally connected in a horizontal plane, adjacent to the first arm assembly, to the gimbal assembly (41). A counterweight arm assembly (72), connecting at one end to a gearbox assembly (64) and connecting at the opposite end to an attachment mounting assembly (87), all vertically connected to the gimbal assembly (41). A mounting stand assembly (80) to rotationally connect to the gimbal assembly (41). An electrical control assembly (100) to controllably power the action arm assembly. The gravity arm and action arm assemblies are balanced about the gimbal assembly by the counterweight arm assemblies. The action arm assembly rotates about the axis of the gravity arm assembly, creating an imbalance in the gimbal assembly, causing the gravity arm assembly to rotate, and the counterweight arm assembly to swing, all in the same direction of the action arm assembly.

An apparatus comprised of positionally directable masses attached to a binding component that includes a coupling device for payload to reduce gravitational deviation of the apparatus' trajectory by alternatingly accelerating and retracting physically bound component masses in equal and opposite directions to the extents of their bindings, initially and optimally perpendicular to the gravitational field and perpendicular to the apparatus trajectory by using in built transduction componentry located within the masses or the binding componentry or both that utilises electromagnetic forces, forces generated by chemical reactions, or other applied or responsive motive force to positionally direct the bound directable masses.

The present invention is a shifting shaft mechanism which may be used with a gravitation engine to enable the gravitation engine to utilize the force of gravitation. The shifting shaft mechanism comprises a shaft, on each side of which shaft is at least one camshaft rotatably connected to the shaft and positioned between at least two fixed plates connected to each other, each of which fixed plates has an off-centre fixed plate opening through which the shaft passes through, and a mobile support wheel rotatably connected to the fixed plates that abuts the camshaft, and wherein when the camshaft rotates with the shaft, the mobile support wheel rotates counter to it. In an embodiment of the shifting shaft mechanism of the present invention, the each side of the shaft has two camshafts, three fixed plates, and two mobile support wheels.

A rotary driving apparatus 1 includes a rotary body 5, rotation detecting means 6, six rotary weight devices 7a to 7f on the body 5, and a power generation device 8. The devices 7a to 7f include a rotary arm 10 rotatably mounted to the body 5, the arms 10 at approximately six-fold symmetrical positions around the point O, a motor 11 to rotate the arm 10 at a rotational speed same as the body 5 in a rotation direction opposite to a rotation direction of the body 5, and a weight 12 on a free end side of the arm 10. The devices 7a to 7f are controlled by the motors 11 such that all the arms 10 are oriented laterally on a same side, and the body 5 is rotated by a weight balance of all the weights 12 on all the arms 10 around the point O.

An engine system includes three communicating fluid vessels that each contain a fluid. A first interconnecting fluid conduit containing the fluid rotatably couples the second fluid vessel to the first fluid vessel and acts as a lever. A second interconnecting fluid conduit containing the fluid rotatably couples the third fluid vessel to the first fluid vessel and acts as another lever. By increasing the fluid column heights in the communicating fluid vessels, torque is applied to the levers to cause the second and third fluid vessels to revolve around the first fluid vessel.

We have discovered that allogeneic HSC-engineered human iNKT (.sup.3rdHSC-iNKT) cells display potent anti-GvHD functions, by eliminating antigen-presenting myeloid cells in vitro and in xenograft models, without negatively impacting tumor eradication by allogeneic T cells in preclinical models of lymphoma and leukemia. The .sup.3rdHSC-iNKT cells closely resembled the CD4.sup.CD8.sup./+ subsets of endogenous human iNKT cells in phenotype and functionality. Embodiments of the invention harness these discoveries in new methods and materials for alleviating graft versus host disease.

Apparatus and methods for generating mechanical energy utilizing gravity and leverage. In one aspect of the invention, a power plant having one or more gravity powered units is adapted to generate mechanical energy, which may be captured and used as mechanical energy or converted to electrical energy for use locally or remotely. The energy may be stored for later use, for example, in the form of electric energy, fluid flow energy, hydraulic energy, compressed air or fluid, or a combination of these. The energy may be stored in any a ro riate stora e medium.
