Alternatively, by distributing the charged product into particulate containing fluid and selecting the polarity such that such particulates tend to agglomerate, expeditious removal of such particulates can be accomplished. The charged product also may be used for distributing mist, distributing ionic material in air, e.g. for sense of wellbeing, and for seeding clouds.

The region is excited by electron cyclotron resonance heating to thereby increase its charged particle density. In one embodiment, circularly polarized electromagnetic radiation is transmitted upward in a direction substantially parallel to and along a field line which extends through the region of plasma to be altered. The radiation is transmitted at a frequency which excites electron cyclotron resonance to heat and accelerate the charged particles.

4712155 - December 8, 1987 - Method and apparatus for creating an artificial electron cyclotron heating region of plasma - A method and apparatus altering a region of plasma that lies above the earth's surface at altitudes (e.g. below 50 kilometer) where the collison rate of the electrons in the plasma is originally greater than the cyclotron frequency of the electrons. First, artificial magnetic lines of force are established from the earth's surface by positioning a loop of cable at the earth's surface. An electrical current of sufficient amperage is passed through the cable which inherently generates the artificial magnetic field from the center of the loop. The field strength B on the artificial lines in the region of plasma to be altered is sufficient to increase the cyclotron frequency of the electrons in the plasma so that it will exceed the rate of collosion of the electrons. The plasma is then excited by electron cyclotron resonance heating to thereby further alter the plasma by transmitting circularly polarized electromagnetic radiation upward in a direction substantially parallel to and along the artificial field lines.

8012453B2 - September 6 2011 - Carbon sequestration and production of hydrogen and hydride - This invention describes a complete sequestration of carbon (CO2 and CO) from coal burning plants. In this process, hydrogen can be generated which in turn permits the reduction in the cost of hydride synthesis. The hydrides store hydrogen for on-board application for automobiles and fuel cells.

The CO and or CO2 produced in coal burning power plants and the heat is used when available for producing hydrogen and hydrides. Carbon is used both as a reactant and as a fuel. Economically hydrogen production cost is comparable to or less than the current price of hydrogen produced from fossil-fuel with the added benefit of carbon sequestration and reducing global warming. Specific processes for synthesizing important hydrogen storage materials, hydrides are described.

This is achieved by applying a charge to the seed particles so that the seed cloud formed by release of the seed particles at altitude is highly charged, which in turn produces a strong electric field between the seed cloud and ground. The relatively strong electric field causes the seed particles to move downward (toward the ground) at a velocity sufficient to increase interaction (collisions) between the seed particles and the target particles.

4470544 - September 11, 1984 - Method of and Means for weather modification - The weather near a continental arid zone is modified by increasing the heat storage of the seas westwardly of the arid zone during the summer. The heat storage is increased by mixing the relatively warmer surface water with relatively cooler deeper water thereby reducing the surface temperature of the seas during the summer. Cooling the surface of the water will increase the radiant heat flux due to solar radiation and decrease the radiant heat loss from the surface during the summer thus increasing the amount of heat stored in the water available for evaporation during the winter. Mixing is achieved by pumping water from a lower level in the seas to the upper level. In one embodiment of the invention, normal wave motion provides the mode of power for the pumping operation. In another embodiment, mixing is achieved by a paddle that is operated by wave motion.

5441200 - August 20, 1993 - Tropical cyclone disruption - A chemical which allows water to chemically join its crystalline lattice is applied to the eye wall of a tropical cyclone to initiate a self destructive catalyzing effect. If applied in powdered form to the upper, center portions of the eye wall, the effect will be greater. Water vapor within the eye wall chemically joins the lattice of the chemical. These larger molecules will also develop through collision and coalesce. Now the vapor of the eye wall is heavier and will spin outwards from Centrifugal Force. As a result of the larger eye, barometric pressure in the eye increases, wind speed slows, and the storm surge decreases to minimal proportions.
