NOVELTY - An electric power generator comprises: at least one lighter than air balloon (LAB) (200) with at least one photovoltaic array (PVA) (250) embedded in its surface and a cable connecting the LAB to the ground and adapted to convey a buoyant gas to an inner volume of the LAB and also to convey an electric current generated by the PVA to a ground installation.    USE - As a lighter than air balloon based electric power generator used in power supply system (Claimed).    ADVANTAGE - The LAB based generators transform light into electricity without occupying precious land area, this contributes to accessibility, portability and reduced infrastructure requirements and these are suitable for use in remote areas and/or at sea. The LAB based generators constitute an affordable, easily installable and durable energy platform that does not affect the environment due to its modular plug-and-play design. Each balloon is manufactured from thin-films of amorphous silicon using a simple, inexpensive, environmentally-friendly process, supporting mass production and accessibility to a wide spectrum of consumers. The device is socially, as well as environmentally friendly, the existing gaps in solar-power accessibility are reduced. This 'acupuncture' technology is suitable for diverse cultural needs and ubiquitous applications, maintaining full accessibility to green places on the ground and as well as on the rooftops. PV technologies are provided in a spatial arrangement that functions as an aesthetic object and sends an educational message in addition to promoting a higher community independence of external energy. The various described embodiments embrace technology as well as addressing the need to make this important energy awareness reachable to all sectors of society. Hanging the PV in the air decreases pollution in cities as well as reduces noise and visual footprint (in warm countries, the system can be lowered and used to produce shading as well). The system can be maintained locally and can serve as an inexpensive, affordable, cost effective, accessible, durable and competitive energy source.    DETAILED DESCRIPTION - An electric power generator comprises: at least one lighter than air balloon (LAB) (200) with at least one photovoltaic array (PVA) (250) embedded in its surface and a cable connecting the LAB to the ground and adapted to convey a buoyant gas to an inner volume of the LAB and also to convey an electric current generated by the PVA to a ground installation. The LAB comprises an upper portion (212) constructed of material transparent with respect to desired wavelengths of incident light (240) and a lower portion (220) adapted to receive the desired wavelengths of incident light on its inner surface; and at least one PVA on an inner surface of LAB. INDEPENDENT CLAIMS are included for the following    (1) an anchored lighter than air balloon (LAB) comprising: an upper portion and a lower portion, each of the portions configured as paraboloid (210) inverted with respect to one another; a circumferential closure (230) joining the upper and lower portions; and an anchor connecting at least three points on the circumferential closure to an anchor point; and    (2) a power supply system comprising several generators deployed in a three dimensional array and connected to one another; and an interface to a ground based power grid.    DESCRIPTION OF DRAWING(S) - The figure shows a schematic representation of an LAB used in the generator.
