A foldable spin flat mop () is disclosed that comprises a handle (); and a mop head () connected to the handle. The mop head comprises: at least two independent cleaning plates (), which together being able to form a coplanar and flat cleaning flat surface; and a connection mechanism disposed to rotatably connect the at least two independent cleaning plates to the handle. The connection mechanism comprises: a plurality of seats () provided respectively at the at least two independent cleaning plates; and at least one joint member () connecting the plurality of seats; wherein each of the at least two independent cleaning plates is rotatable with regard to the joint member, such that the at least two independent cleaning plates each is capable of freely rotating relative to the handle.

The present disclosure relates to a body-building power generation apparatus and a method of generating power using the power generation apparatus, comprising at least one fitness device, an energy storage device connected with the fitness device for transforming and storing the kinetic energy transmitted from the fitness device, wherein the energy stored in the energy storage device can be transformed into kinetic energy and outputted by an output mechanism connected with the energy storage device, a speed changing mechanism, receiving the kinetic energy from the output mechanism and outputting said kinetic energy after adjusting it, and a generator connected to the speed changing mechanism for transforming the adjusted kinetic energy into electric energy. The body-building power generation apparatus according to the present disclosure can satisfy or at least partially supplement the need of electricity in residential areas, office buildings, or leisure facilities; it can also act as backup power source to alleviate piezoelectricity or power failure in rush hours.

Provided is a process for directly producing sulfur trioxide and sulfuric acid from gypsum. Sulfur trioxide is directly substituted with silicon dioxide by thermal or light-quantum activation, which is assisted with catalytic activation, while restraining reducing atmosphere and removing the resultant sulfur trioxide in time. The resultant sulfur trioxide is then used as raw material to produce sulfuric acid by a well-known method in prior art. The process has the advantages of simplified operational steps, little investment, low energy consumption and manufacturing cost, and low environmental pollution.
