NOVELTY - An electromagnetic radiation extraction and collection system comprises a supply of fluid; a first arrangement to collect some of electromagnetic radiation released by the fluid; a second arrangement having a closed passageway defining a given path for containing the fluid along the path; and a third arrangement including a Casimir cavity positioned within the given path and cooperating with the second arrangement such that the fluid is caused to pass into and out of the cavity as the fluid is contained along the given path.    USE - For extracting and collecting electromagnetic radiation from ambient surroundings.    ADVANTAGE - The system can radiate the accumulated energy locally and absorb it globally.    DETAILED DESCRIPTION - An electromagnetic radiation extraction and collection system comprises:    (1) a supply of fluid characterized by its ability to (i) take in electromagnetic radiation from ambient surroundings and (ii) release at least some of the energy when the fluid is caused to pass into a Casimir cavity;    (2) a first arrangement configured to collect at least some of the electromagnetic radiation released by the fluid;    (3) a second arrangement including a closed passageway defining a given path for containing the fluid along the path; and    (4) a third arrangement including the Casimir cavity positioned within the given path and cooperating with the second arrangement such that the fluid is caused to pass into and out of the cavity as the fluid is contained along the given path.    The Casimir cavity is positioned in sufficient communication with the ambient surroundings and with the first arrangement to (i) cause the fluid containing electromagnetic energy taken from the ambient surroundings to release at least some of the energy to the first arrangement when the fluid passes into the cavity and (ii) to again take in electromagnetic energy from the ambient surroundings when the fluid passes out of the cavity. The first arrangement includes a container of material for absorbing electromagnetic energy, where the absorbing material surrounds at least the Casimir cavity. An INDEPENDENT CLAIM is included for a method of extracting and collecting electromagnetic radiation from the ambient surroundings.
