The present invention relates to wobbly balls and exercise coil springs. A wobbly ball may include a non-spherical rigid, hollow ball body formed of two halves, each half comprising an upper ladle or a lower ladle which are welded together along a central seam therebetween, and defining a hollow cavity therein. A spherical inner ball is captured within the hollow cavity of the hollow ball body of the wobbly ball, so that upon movement of the wobbly ball, the inner ball rolls within the cavity, producing a wobbly, eccentric motion. The exercise coil spring may be formed of a single coiled wire, the coiled spring including a central portion where the coiled wire is coiled to a first diameter that is constant. Opposed flared ends are provided ends of the central portion where the coiled wire is progressively coiled from the first diameter to a second diameter, which is greater.

A biomechanical electricity generating assembly for powering electronic devices includes a sleeve that has opposing ends, which are open. The sleeve is configured to insert a limb of a user to couple the sleeve to the user with the sleeve positioned over a joint of the limb. Each of a pair of bars is coupled longitudinally to a respective opposing side of the sleeve. Each bar comprises a first section that is pivotally coupled to a second section. Each of a pair of dynamos is coupled to a respective opposing side of the sleeve and is operationally coupled to an associated bar. Pivoting of the first section of the associated bar relative to the second section by action of the user articulating the limb actuates the dynamo to generate an electrical current.

A device for harvesting energy from fabric or clothing includes a piece of fabric or clothing. One or more piezoelectric harvesters are coupled with the piece of fabric or clothing.

A human-powered pump assembly includes a frame and a treadle pivot attached to the frame, such that the treadle pivot defines a horizontal rotational axis. The pump assembly includes a pair of treadles coupled to the treadle pivot and a rocker pivot attached to the frame, such that the rocker pivot defines a separate horizontal rotational axis. The pump assembly includes a reciprocating rocker coupled to the rocker pivot and to the pair of treadles to constrain the motion thereof, such that the rocker pivot axis is located below the treadle pivot axis.
