Abstract: Vehicles with integrated power generation produced by rotation of the wheels are provided. In exemplary implementations, a vehicle includes a frame, a wheel assembly coupled to the frame, and a power generating unit. The wheel assembly includes a wheel defining a wheel axis. The wheel is configured to rotate about the wheel axis during operation of the vehicle. The wheel assembly further includes supporting components fixed about the wheel axis during operation of the vehicle. The power generating unit includes a rotating assembly rotatable with the wheel about the wheel axis, including at least one of a magnet assembly or a coil assembly, and, also includes a stationary assembly mounted to at least one of the supporting components of the wheel assembly or the frame and including the other of the magnet assembly or the coil assembly such that rotation of the wheel rotates the rotating assembly relative to the stationary assembly for generating electrical power.

Abstract: A solar array may have a primary solar panel attached to a supporting structure and an auxiliary solar panel attached at an angle to the primary panel. The primary solar panel may be positioned to collect daily solar radiation and the auxiliary solar panel may be positioned relative the primary panel to collect daily solar radiation. The daily solar radiation collected by the primary solar panel may be peak annualized daily solar radiation and the daily solar radiation collected by the auxiliary solar panel may be off-peak solar radiation.

Abstract: An apparatus for capturing energy of a working mass may include two or more immiscible liquids having different densities. The two immiscible liquids may include a predetermined proportion of oil and water. The apparatus may include a supporting structure, a hermetically sealed vessel, and an electric generator driven by fluid flow. The hermetically sealed vessel may have an elongate shape housing the working mass such that the working mass moves within the hermetically sealed vessel. An electric generator driven by fluid flow may be housed within the hermetically sealed vessel and having an inlet and an outlet. The electric generator driven by fluid flow may be configured to produce electric power as the predetermined portion of oil and water passes into the inlet and out of the outlet in response to a movement of the hermetically sealed vessel.

Abstract: A refrigeration and/or heat transfer device includes a heating section and cooling section, a release member, and a one-way check valve affixed together in a continuous loop so working fluid may flow in one direction therein. The heating section absorbs heat and transfers such heat to the working fluid, thereby heating, expanding and increasing pressure upon the working fluid therein. The pressurized working fluid is released in a regulated manner from the heating section to the cooling section, thereby carrying the heat away. The released working fluid cools and transfers its heat to the surroundings within the cooling section. As released working fluid enters the cooling section, such fluid displaces already cooled working fluid, pushing such fluid through the one-way check valve back into the heating section to absorb heat. The working fluid may undergo a phase change or remain in a single phase throughout to enhance heat transfer.

Abstract: Horizontal axis wind turbines are provided that have a rotor including a hub having at least one blade extending therefrom. A first rotatable member is coupled to the rotor and configured to rotate in relation to wind-induced rotation of the rotor. A tower supports the rotor and has a base. A second rotatable member is spaced from the first rotatable member toward the base of the tower. An endless member engages the first rotatable member and the second rotatable member to convey a rotational force therebetween. An electrical generator is coupled to the second rotatable member.

Abstract: The invention is an apparatus for generating power using inertia of a load in a moving vehicle. The apparatus includes a vessel having a volume that is capable of an expansion and a contraction, and containing a fluid under a pressure. The fluid is released from the vessel as a force is exerted by the load of the vehicle against the vessel. The apparatus includes a reservoir, operably connected to the vessel by fluid conduit. The reservoir contains the fluid under pressure until an optimum pressure is reached at which point the reservoir releases the fluid to a power generator. The power generator then generates electrical power. Excess fluid released from the power generator then returns to the vessel.

Abstract: A power generator may generate power using buoyancy having a fluid column contained by a tank having a sealable drain and a piston having a substantially hollow interior capable of being filled with a fluid. The piston has a sealable outlet, a vent, an inlet, and a lateral cross-section that is smaller than a lateral cross-section of the tank. A rod is connected to the piston and a power generator is connected to the rod. The piston operates from a first position near the top of the fluid column to a second position near the bottom of the fluid column. The piston moves from the first position to the second position as fluid is added to the inlet. The piston moves from the second position to the first position as the fluid is drained from the outlet.
