  • Publication number: 20240086934
    Abstract: Disclosed is a system and method for identifying various combinations of parcels of land with sufficient transmission, resources, market demand, and available land to build a wind farm or solar farm. Different criteria associated with each parcel of land include land characteristics including size, ownership, tree coverage, elevations, terrain, buildable land, transmission characteristics including substation hardware costs, network upgrades, general tie-in costs, market characteristics including historical locational marginal pricing (LMPs), and resource characteristics including net capacity factor (NCF) of wind or solar. In one example, the present invention identifies clusters of land parcels that minimize the number of land owners, maximize buildable land, minimize transmission cost, maximize NCF, and maximize nodal LMPs.

  • Publication number: 20170282476
    Abstract: A super compactor receives a carbon-containing material and delivers a brick suitable as fuel for power generation. A compaction chamber receives the carbon-containing material and has at least one ram reciprocating along a travel path and exerting a predetermined amount of pressure on the carbon-containing material. The compaction chamber also has an end effector plate or a movable slide gate against which the carbon-containing material is compressed, promoting the removal of moisture from the carbon-containing material, and one or more dewatering apertures or a membrane permitting moisture to pass through but blocking the carbon-containing material. A collector captures the moisture that passes through the dewatering apertures or membrane. A power unit provides power to the at least one ram. A heated extrusion chamber receives the carbon-containing material from the compaction chamber and heats and compacts the carbon-containing material to bind the carbon-containing material into the form of a brick.

  • Patent number: 5008679
    Abstract: The method of locating an unknown radio-frequency transmitter includes: (a) receipt of signals radiated from the transmitter by a plurality of receivers; (b) retransmission of the received signals to a plurality of antennas; (c) performing a time difference of arrival (TDOA) calculation which compensates for a relative delay value, which is a function of the distances from the transmitter to each of the receivers, the distances from each of the receivers to the antennas, and the speed of light; (d) performing a frequency difference of arrival (FDOA) calculation which compensates for a relative frequency value, which is a function of the relative velocity of each receiver with respect to the velocity of the Earth; (e) repeating these steps a plurality of times; and (f) determining the location of the unknown transmitter based on the plurality of TDOA and FDOA calculations.
