Abstract: A desalination plant, includes a sea water intake, a desalination unit having a reverse osmosis or a thermal desalination unit, a fresh water outlet and a brine outlet. The plant also includes a salinity gradient power unit having a brine inlet, a seawater inlet and a mixed water outlet. The brine outlet is connected to the brine inlet and the salinity gradient power unit is arranged to generate an electrical current. A solar power heater is between the brine outlet and the brine inlet. A method for reducing the power consumption of a desalination plant providing fresh water and brine from sea water, includes a first step of providing a salinity gradient power unit, a next step of feeding the salinity gradient power unit with brine from the desalination plant as high salinity feed and sea water as low salinity feed.

Abstract: A three-dimensional (x?-axis, y?-axis and z?-axis based) combined light-based apparatus for measuring the absolute velocity and acceleration of a material object in space. The apparatus has for each axis, while each axis is perpendicular to each other axis, an identical set-up of: a photon (light) emitting source; zero to multiple mirrors; a photon sensitive sensor, possibly CCD-based. The emitted photons are directed to the sensor with or without one or multiple reflections from zero to multiple mirrors. The photons, emitted by the source, arrive at the sensor at a location determined by the momentarily absolute velocity of the apparatus in Newton's absolute space; the absolute velocity of the apparatus thus being calculable from this location on the sensor by adequate mathematical formulas.

Abstract: The invention concerns a process for preparing glass, more specifically glass powder or glass films, together with a process for conditioning the raw materials intended for preparing glass characterized in that raw materials are converted to freely flowing powder suitable for feeding to a plasma torch in which the powder is converted to glass.
