Resumen de: US2025369419A1
Disclosed systems and devices relate to generating energy using spherical wind turbines with dimples. The systems, devices, and methods described herein relate to a wind turbine with no blades or propellers. Currently, wind turbines with blades or propellers can have their functionality impaired by the presence of dust, soot, or ash particles in the air. This makes it difficult to operate current wind turbines in certain harsh environments. In this device, a spherical shell entirely encapsulates the generator, such that dust, soot, or ash particles do not interfere with the turbine. In some embodiments, the dimples capture wind to rotate the spherical shell. In some embodiments, the outer surface of the spherical shell is covered with flexible solar cells. In some embodiments, the flexible solar cells sit inside the dimples.
