A flash memory system segregates overhead data from user data so that overhead data may be address, programmed and erased independently from user data. The non-volatile memory medium of a flash memory system is mapped into a plurality of separate and separately addressable memory blocks that are independently programmable and independently erasable, including Dedicated Overhead Blocks and Dedicated Data Blocks. The Dedicated Overhead Blocks are mapped according to a plurality of distinguishably addressable segments. User Data defined by a VLBA is stored in a Dedicated Data Block within the flash memory. Successively generated sets of Overhead Data, such as a cross reference to the physical address of the user data, flags, and Error Correction Data generated in conjunction with incoming User Data, are stored in respective segments in the Dedicated Overhead Blocks. When a Dedicated Overhead Block is designated for erasure, any current overhead segments are consolidated and moved to a new Dedicated Overhead Block., and the full or obsolete block is erased.

The invention relates to a method and apparatus for using solar energy to enhance the efficiency of a compressed air energy storage system (and visa-versa). The apparatus comprises a photovoltaic panel to drive a compressor, which provides compressed air energy into an inner vessel housed within a storage tank. Two solar receiving panels are used to heat water which can be circulated and stored within an annulus surrounding the inner vessel, wherein the heated water can help regulate the temperature of the compressed air within the tank. This way, when air is released using a turbo expander, any excess temperature drops that can otherwise result from air expansion can be avoided. The overall system efficiency is enhanced by the chilled air by-product of the turbo expander which is used to generate more electrical power from an associated fuel-driven generator set, and / or by the waste heat from the compressor and from the generator set exhaust which is used in a Combined Heat and Power system (CHP) to power either a steam-driven generator set or an absorption chiller.
