Abstract: The mobile hybrid electrical power source (100) is reconfigurably disposed in a street-legal size compact metallic container (105) positioned on a hydraulic trailer (107) that can be towed by a truck. An alignment pin (109) is provided on the container (105) for aligning and mating the container with a rotary bearing (111) on the trailer (107). The rotary bearing (111) allows the metallic container (105) to rotate about a vertical central axis +/?180° from an initial position of the container (105). The generator (100) combines a plurality of power sources to provide optimal operation in multiple applications and conditions. The power sources comprise wind, solar, and fossil fuel energy components. When a power grid is available, the mobile hybrid electrical power source (100) can be connected to the grid to sell energy back to the grid.
