A vehicle transaxle comprising a plurality of mounting flanges fixedly mountable to an axle tube of the vehicle absent any additional structure for mounting the transaxle to the vehicle. The axle tube houses a wheel axle to which the transaxle is operably couplable. The transaxle additionally comprises a transaxle mounting collar that is fixedly mounted to or integrally formed with a housing of the transaxle. The mounting collar is structured and operable to have a prime mover of the vehicle mounted thereto and to support the weight/mass of the prime mover such that the prime mover is mountable to the vehicle via only the mounting collar absent any additional structure for mounting the prime mover to the vehicle such that the prime mover can be cantilevered from (e.g., suspended from) the transaxle, e.g., the prime mover is free floating.

A rotary device comprises a frame with a guide for flowing medium, a rotor with a number of blades, whereby a relation is obtained between the flowing medium and the rotation of the rotor, and energy converting means, the one part of which is connected to the frame and the other part to the rotor. The device has the feature that the end zones of the blades are connected to a ring, the ring has a radial section with the shape of an isosceles triangle or trapezium, the medium guide has an encircling recess, the form of which corresponds to the form of the ring and the ring fits with clearance into the recess, permanent magnets are added to the truncated conical surfaces, electromagnets debouch on both the corresponding surfaces of the recess, this such that the ring and the frame together form an annular induction motor or an electric generator.

A transportation vehicle may be equipped with electrical energy harvesting systems to harvest electrical energy for use. By way of example, in the transportation vehicle, a Venturi system may be used to receive an air flow and the speed of the air flow increase in a constricted area of the Venturi system, the air flow containing a large amount of kinetic energy. A plurality of electrical energy harvesting systems is disposed in the Venturi system and is configured to convert the kinetic energy contained in the accelerated air flow into electrical energy that can be used to power on-board electronics as well as one or more on-board batteries in the transportation vehicle, as the transportation vehicle is in motion.

The invention relates, among other things, to a method of making a thin panel (10) for outdoor applications, comprising, among other things, the following steps: a) providing a deep-drawable film (10) of a transparent plastic, b) deep-drawing the film (11) in a mold (34), c) mounting a structure (19) having solar cells (32) on an inner face (16) of the deep-drawn film (12), d) placing the deep-drawn film (12) with mounted structure (19) in a cavity (33) of a mold (34) having in particular at least two mold halves (13, 14), e) introducing a liquid polyurethane casting compound (24) into the cavity (33) of the mold (34) and spreading the polyurethane casting compound (24) over an inner face (18) of the structure (19) and/or over the inner face (16) of the film (12), f) curing the polyurethane casting compound, in particular with the mold closed, to form a reinforcement layer (30), or comprising the following steps j) and k) instead of the steps e) and f): j) introducing a granular particle foam mass into the cavity (33) of the mold (34) and spreading over an inner face (18) of the structure (19) and/or over the inner face (16) of the film (12), k) baking and curing the particle foam mass, in particular with the mold closed, to form a reinforcement layer (30).

This presents a Utility Model related to an improvement introduced in a piece of equipment conceived to capture wind power generated by the displacement of trains, subways, vehicles in generaloverall trucksalong railroads, roads, etc., and to convert it in electrical power, thus using such considerable energetic potential. Considering that the assembly of one or a plurality of wind rotors (P) and respective electricity generators (G) are assembled on semi-tows (K) of the type engaged and handled by a truck (mechanical horse), considering that the trailers (K) provided with means for storing the electrical power generated, such as batteries (B), or other means for electricity transmission and storage. Thus, the aerogenerators (P) may be displaced to the points with the biggest flow of passing vehicles, and may also be positioned on the direction where the natural (predominant) winds are favorable to the best use of the wind potential.

A power feeding system of the present disclosure includes a control unit. In a case where a magnitude of supply destination power is smaller than an upper limit value of the power supply capability of the power source, the control unit controls the charge/discharge control circuit so as to meet the supply destination power based on power output from the power source, and to charge the storage battery with power which is a difference obtained by subtracting the supply destination power from the upper limit value of the power supply capability of the power source. In a case where the magnitude of the supply destination power is more than or equal to the upper limit value of the power supply capability of the power source, the control unit controls the charge/discharge control circuit so as to meet the supply destination power by both the power source and the storage battery.
