An electromagnetic vehicle chassis that is configured with an upper portion and a lower portion wherein the upper portion is movable to a second position and supported therein with an electromagnetic field. The vehicle of the present invention includes a frame having the upper portion movable so as to reduce the overall vehicle weight and as such require less propulsion force resulting in reduced energy consumption. The upper portion of the frame of the present invention is moved into its second position utilizing hydraulic cylinders. Electromagnets present on both the upper portion and lower portion maintain the upper portion in its second position. A battery compartment having a plurality of batteries is operably coupled to the lower portion of the frame. The body of the vehicle includes a plurality of photovoltaic cells electrically coupled to the plurality of batteries.

A vehicle is capable of receiving electric power supplied from a charger and capable of receiving electric power supplied from a charging mat. The charging mat is movable and capable of wireless power transfer. A method for providing a vehicle charging service includes a first step and a second step. The first step is giving, by a server, an instruction for installing the charging mat on a lane at which charging congestion is detected or predicted to occur, the charging congestion being traffic congestion for charging the electric power supplied from the charger. The second step is transmitting the electric power from the charging mat when the vehicle is detected above the charging mat installed on the lane in accordance with the instruction, and transmitting no electric power from the charging mat when the vehicle is not detected above the charging mat.

An airship and its long-term floating capacity maintenance method are disclosed. The airship includes an airship capsule and a pod at bottom. A renewable fuel cell and a water tank communicated with each other are arranged in the pod. The water tank is provided with a water inlet connected with a filling aircraft outside the airship. The airship capsule is provided with a solar cell. The interior of the airship capsule is provided with a hydrogen storage bag. The solar cell is electrically connected with the renewable fuel cell. The renewable fuel cell can use electric energy provided by the solar cell to electrolyze water provided by the filling aircraft into hydrogen and supplement the hydrogen to the hydrogen storage bag. The airship can supplement hydrogen to the airship capsule by electrolyzing water to reduce the phenomenon of insufficient gas in the airship capsule.

A solar charging system for the vehicle includes a first photovoltaic (PV) module, a second PV module serially connected to the first PV module, and a differential power processing (DPP) transformer that converts power generated from the first PV module and the second PV module by using a magnetic body having a multi-winding structure.
