Patent ID: 8552573

Claim:
An apparatus for harvesting impact energy of raindrops, comprising: a mechanical converter comprising a plurality of rips, wherein each said rip comprises two sheets of thin metals filled with silicone gel, each rip being provided with a sealing cap at each end; each of said caps having a first end and a second end; said first end being connected to one of said plurality of rips; metal sheets connecting the caps of said plurality of rips at respective ends; wherein said caps are allowed to move in an element of a ditcher having a substantially frictionless track; a first rod attached to each of the metal sheets and transfers a force from the rips to a mechanical capacitor; wherein the mechanical capacitor is a three-dimensional trapezoid shape filled with silicone gel, with an inlet side and an outlet side made of elastic material and the remaining sides, being made of rigid material, each of said mechanical capacitor being fixed to a stationary element, and said first rod being connected to the inlet side of the capacitor; the outlet side being connected to a second rod; the inlet side having larger cross section than the outlet side; a force from the first rod is transferred to the second rod through the mechanical capacitor; the second rod is adapted to be attached to an electromagnetic induction element; wherein impact of the rain drops on said rips causes displacement of said rips, which in turn causes displacement of said first and second rods, thereby generating electricity by induction.
