Deep ocean energy system with full sea water air conditioning and utility waste heat utilization

An enhanced-air conditioning system for tropical and sub-tropical island sea coast environments having access to deep ocean sea water. Sea water from depths of at least about 1200 feet, at a temperature of 47° F. or lower, is utilized as a source for circulating chilled water loops providing district wide air conditioning, in some instances with assistance from electrically driven chillers. The sea water is then further used to condense working fluid in a low temperature Organic Rankine Cycle or Kalina Cycle turbine generator, the heat source for which is the cooling jacket of a diesel engine generator, and also to condense working fluid in a steam driven Rankine Cycle turbine generator, the heat source for which is exhaust heat from the diesel engine. Alternate heat sources, if available, can be utilized. Additional electrical generation from these sources far exceeds the costs of pumping the sea water.

Large-size high-speed invisible flying saucer

The invention discloses a flying saucer and two smoke- and fire-free engines. The flying saucer is composed of a cabin and a disk which rotates round the cabin. The disk includes a disk-shaped wing and a rotary engine. The cabin includes a driving cabin, a passenger cabin and a device cabin. The rotary engine sucks air which is mixed with water, and then the mixture is jetted out horizontally through jet tubes installed on the edge of the disk according to the sprayer principle, so that a generated reactive force enables the disk to rotate at a high speed, thereby generating an upward raising force on the disk. Four fixing wings are installed outside the device cabin to eliminate reverse rotation of the cabin. A vector engine and a diesel power generating set are installed in the device cabin under the disk. The vector engine sucks large amount of air through an air inlet duct in the passenger cabin to form vacuum above the passenger cabin, which enables air pressure difference between an upper surface and a lower surface of the disk to be increased, thereby generating a huge raising force. The sucked air is compressed to form high-pressure gas which is discharged into vector jet tubes and is jetted out, wherein the directions and the angles of the vector jet tubes are adjustable to generate pushing forces in different directions, thereby achieving maneuvering flight of the flying saucer.
