Electricity generating apparatus, has magnets free falling down shaft surrounded by magnetic fields and returned to top of shaft by floating up inside column of liquid

摘要

A free-falling body comprising a magnetic material transfers its kinetic energy to one or more (very) high strength magnetic fields (17) extending around at least part of the shaft (12A) defining the fall or roll trajectory and these fields brake the fall, the counter-reaction to which is the supply of electrical current by the coils and magnets due to changing voltage ratios. The magnets are returned to the top of the shaft by a hydraulic system (11B) comprising a column of liquid with a transfer device (14) for supplying the fallen bodies to the bottom of the column, which the bodies float to the top of for another fall cycle. The magnetic fields can extend around at least part of the liquid column.
