A solar central receiver system employing common positioning mechanism for heliostats relates to a system of concentrating and harvesting solar energy. The heliostats of said system are positioned like facets of a Fresnel type of reflector. The heliostats are placed in arrays, wherein each array has a common positioning mechanism. The common positioning mechanism synchronously maneuvers the arrays of heliostats in altitudinal and/or azimuthal axis for tracking an apparent movement of the sun. The common positioning mechanism is employed for synchronously orienting said heliostats with respect to a stationary object and the sun such that incident solar radiation upon said heliostats is focused upon said stationary object from dawn to dusk. Subsequent to each said orientation of said heliostats, collective disposition of said heliostats always forms an arrangement that is capable of reflecting and thereby focusing incident solar radiation upon said stationary object.

A solar photovoltaic system including a liquid filled lens configured to concentrate sunlight for the generation of electricity, desalination of water or production of steam. The liquid lens and receiver are mounted on a tracker. The complete system is lightweight and modular with multiple configurations possible. The liquid lens is manufactured using an improved method.

The use of a liquid lens for the purpose of collecting solar energy is novel.

A novel method of concentrating solar energy using wave generators is disclosed. The systems and methods enable the collection of energy over large area at high efficiencies and the concentrating of energy at a target for use and transfer.
