A mobile generator includes a housing having a top portion, a first side portion, and a second side portion, wherein the first side portion includes an energy-receiving component. The mobile generator also includes an arm pivotally coupled to the housing at a first pivot point and to the first side portion at a second pivot point. A first motion controller is configured to drive rotation of the arm about the first pivot point, and a second motion controller configured to drive rotation of the first side portion about the second pivot point.

A transportation vessel includes a first sidewall and an opposing second sidewall. A load bar has a first end and a second end. The load bar is movable between a horizontal orientation and a vertical orientation. In the horizontal orientation, the first end is attached to the first sidewall and the second end is attached to the second sidewall, and the load bar may support cargo while the cargo is being transported in the transportation vessel. In the vertical orientation, the first end is attached to the first sidewall and the second end is unattached to the second sidewall.

A trailer includes a set of removable castor wheels attached to a rear portion thereof, wherein the castor wheels are oriented to face rearwardly when the trailer is oriented in the traditional horizontal position. This arrangement allows the trailer to be tilted upwardly into a vertical orientation so that it rests on the castor wheels, thus providing an apparatus and method for easily moving and storing trailers more efficiently due to the reduced footprint required for such trailer storage. The castor wheels, in one embodiment, include mounting brackets that may be attached to the trailer using a securing rod, similarly to the mounting mechanisms commonly used for removably attaching trailer hitches into trailer hitch sleeves, thus rendering the castor wheels removable from the trailer when they are not in use for storage purposes.
