Abstract: A renewable energy system comprising: a cylindrical closed circulated wind tunnel, an electric turbine engine is mounted on the inside wall of said wind tunnel, numerous wind electric generators are mounted on the inside wall of said wind tunnel, also numerous aerodynamic air fins are mounted on the inside wall of said wind tunnel. An electric motor is coaxially mounted on said electrical turbine engine. A solar cells panel is provided to supply the said electric turbine engine with solar electricity. Also an air compressor is provided to supply compressed air into said closed circulated wind tunnel.

Abstract: A fashion umbrella comprises: an umbrella shank, a ring around the shank, numerous umbrella ribs connected at the upper end of the shank and extend outwardly to tips, numerous spreaders connected to said ring and extend outwardly in radius configuration and connected to said umbrella ribs. A hollow umbrella handle attached at the lower end of said shank. A battery is housed into hollow handle. Electric wires are housed into the said hollow shank and extend to the tips of said umbrella ribs. Numerous light bulbs are mounted on the tips of said ribs, said light bulbs are connected to said battery through said electric wires, an electric switch is provided to turn said light bulbs ON and OFF. A fiber optic system is mounted on said shank under the canopy of the umbrella; a single cable often contains many separate fiber optic filaments, allowing multiple light signals to be transmitted to tips of said ribs of the fashion umbrella.

Abstract: A new renewable gravity, wind and solar energy engine, comprising: an engine block which houses a crankshaft, flying wheels and mechanical transmissions, a fulcrum is mounted on top of said engine block, a straight lever is mounted on the fulcrum and has connecting pins on the ends across the fulcrum; the connecting pins are connected to connecting rods, said connecting rods are connected to said crankshaft. An electric motor vehicle with wheels and loaded with heavy masses moves on the straight lever forward and backward from one end to the other end of the straight lever over the fulcrum. The heavy masses generate force at the ends of the lever which forces the connecting rods to move downward and upward reciprocally to convert lever drive into rotary movement of the crankshaft.

Abstract: A multivalve internal combustion engine which has a cluster valve system, said system comprises a cam on a camshaft, a valve stem with a valve spring, a cluster valve lever mounted on a lower end of said valve stem, said cluster valve lever has a plurality of holes and a plurality of valves. Said valves are inserted into said holes of said cluster valve lever respectively, and secured by mated nuts that are tightened by application of torque to make the cluster valve system to operate as one single valve.
