Thermal energy storage system with forecast control of operating parameters
An energy storage system converts variable renewable electricity (VRE) to continuous heat at over 1000° C. Intermittent electrical energy heats a solid medium. Heat from the solid medium is delivered continuously on demand. An array of bricks incorporating internal radiation cavities is directly heated by thermal radiation. The cavities facilitate rapid, uniform heating via reradiation. Heat delivery via flowing gas establishes a thermocline which maintains high outlet temperature throughout discharge. Gas flows through structured pathways within the array, delivering heat which may be used for processes including calcination, hydrogen electrolysis, steam generation, and thermal power generation and cogeneration. Groups of thermal storage arrays may be controlled and operated at high temperatures without thermal runaway via deep-discharge sequencing. Forecast-based control enables continuous, year-round heat supply using current and advance information of weather and VRE availability. High-voltage DC power conversion and distribution circuitry improves the efficiency of VRE power transfer into the system. |

A robotics-assisted foundation installation system is provided in which data reporting the X, Y, and Z positions of foundation column tops are sent from a total surveying station to a grid control system. The grid control system receives the data and associates specific data with specific columns in an array—the “grid.” The grid control system compares the actual positions of the columns in the grid to target positions that were determined based on the requirements of the structure to be supported. After determining differences between the actual positions and the target positions, the grid control system sends instructions to column positioning tools associated with the individual columns. Actuators in a column positioning tool are directed by the grid control system to adjust the position of the associated column. Once the live streamed data confirms that each column is in the proper position, the columns are fixed in place. |

Method of preparing potable water
A method of removing organic carbon and other contaminants from a water stream. The method comprises screening large solids from the stream. Pre-oxidation chemicals may then be added. A coagulant is fed into the stream. An activated carbon, preferably formed from lignite, is added by pumping a highly concentrated activated carbon slurry into the stream.

Auxiliary propulsive control for enhanced taxiing performance of seaplanes
Exemplary inventive practice improves the taxiing dynamics of a seaplane by propulsively imparting roll moments so as to continually encourage levelness of the two wings, thereby maintaining both wings completely above (out of) the water. Two matching motor-driven propellers are correspondingly positioned at or near the wingtips. A computer receives sensory motion inputs and transmits sequential commands that continually adjust the respective propulsive forces of the wingtip propellers by effecting equal and opposite changes in their respective rotational speeds. An increase in one wingtip propeller's rotational speed is concomitant a decrease in the other wingtip propeller's rotational speed, wherein the increase and the decrease are of the same magnitude. The seaplane rolls upward on the wing whose wingtip propeller is increasing in rotational speed. Control of the seaplane's rolling motion is thus enabled by a sustained propulsive equilibrium between the two wingtip propellers. |
