Fluid flexible container pump

A non-linear system for use in generating electricity from mechanical energy comprising:

• a non-linear plunger having a mid-portion with an arcuate shaped exterior surface wherein the non-linear plunger is operably connected to a mechanical energy source;
• a flexible fluid filled container, operably connected to the non-linear plunger, wherein the first flexible fluid filled container is comprised of one of elastomers, coated fabrics, and multi-ply composites, and wherein fluid is contained within the flexible fluid filled container, wherein a portion of the flexible fluid filled container is rolled onto the arcuate shaped exterior surface of the non-linear plunger, such that the non-linear plunger plunging towards the fluid filled container causes a portion of the flexible fluid filled container to roll along the arcuate shaped exterior surface of the plunger;
• fluid, wherein fluid is expelled from the flexible fluid filled container when the plunger is moved toward the flexible fluid filled container by the mechanical energy source;
• and
• a generator to generate electricity using the expelled fluid.

A non-linear system for use in converting an objects movement into fluid movement comprising:

• a non-linear plunger having two ends and a mid-portion with an arcuate shaped exterior surface, the non-linear plunger operably connected to a moving object;
• a fluid inflatable container having a flexible membrane engaging with the non-linear plunger, wherein the flexible membrane rolls onto the arcuate shaped exterior surface of the non-linear plunger, such that inflation of the fluid inflatable container causes a portion of the flexible membrane to unroll from the arcuate shaped exterior surface of the plunger;
• an opposing plunger operably connected to one end of the non-linear plunger;
• an opposing fluid container which engages the opposing plunger;
• and
• a fluid communicator, wherein the fluid inflatable container and the opposing fluid container are in fluid communication, and
• wherein the moving object causes the opposing plunger to plunge into the opposing fluid container causing the opposing fluid container to expel some of its content.

An apparatus comprising:

• a drum;
• a shaft passing longitudinally through the drum;
• two or more casters, operably connected to the drum and the shaft, wherein the shaft and the drum move relative to each other;
• a non-linear plunger housed within the drum and connected to the shaft;
• a first fluid inflatable container housed within the drum and operably connected to the plunger, wherein the first fluid inflatable container comprises a flexible membrane which rolls when deflated;
• a second fluid inflatable container housed within the drum and in fluid communication with the first fluid container;
• wherein relative motion between a shaft and the drum will cause non-linear movement of the non-linear plunger within the drum and, when the non-linear movement of the non-linear plunger is towards the first fluid inflatable container, the non-linear movement will cause fluid to move from the first fluid container to the second fluid container.
