Abstract: A multifunctional floating apparatus, which is able to float on water, includes a floating device, a handrail, a driving device, a controlling device, and a battery set. The floating device has an exterior edge and an interior edge, wherein the exterior edge is longer than the interior edge, and the floating device has an inner side at the interior edge. The handrail is connected to the inner side of the floating device, wherein the handrail has at least a holding portion for a user to hold the handrail. The driving device is provided on the floating device to drive the floating device to sail on water. The controlling device is electrically connected to the driving device to control the controlling device. The battery set is disposed to the floating device to supply the driving device with electric power.

Abstract: A power-generating plug-and-play vehicle is provided, which includes a main vehicle body, a plurality of solar cell units coupled to the vehicle, a gear-driven power unit, a power storage unit, an accelerator unit and a drum-motor-driven power unit. The plurality of solar cell units are capable of converting solar energy to electrical energy, which is in turn stored in the power storage unit. The gear-driven power unit converts mechanical energy to electrical energy, which is also stored in the power storage unit. The accelerator unit and the drum-motor-driven power unit convert between mechanical energy and electrical energy, thereby appropriately adjusting the means for driving the main vehicle body. The plurality of solar cell units may be removed and the angle at which the solar cell panel is mounted may be adjusted via gearing of the solar cell panel and the gear-driven power unit.
