Techniques for the efficient generation of electric current by translation of force through hydraulic coupling

A method of generating an electric current with an apparatus, the apparatus comprising:

• a hollow chamber having a first end and a second end,
• an inner core member located within the hollow chamber and movable axially along the hollow chamber,
• a conductive coil arranged about the hollow chamber, and
• an outer fixed magnetic structure about the hollow chamber,
• the method comprising:
• receiving fluid at the first end for acting on the inner core member for causing the inner core member to move axially along the hollow chamber thereby inducing an electric current within the conductive coil,
• wherein the inner core member is a permanent magnet,
• the fixed magnetic structure comprises a permanent magnetically charged member and a magnetically permeable coupling member arranged about the hollow chamber, and
• the conductive coil comprises a first conductive coil and a second conductive coil, the first conductive coil is arranged about the outer magnetic structure and the second conductive coil is arranged between the hollow chamber and the magnetically permeable couple member.
