  • Publication number: 20230314655
    Abstract: Surface modification control stations and methods in a globally distributed array for dynamically adjusting the atmospheric, terrestrial and oceanic properties. The control stations modify the humidity, currents, wind flows and heat removal rate of the surface and facilitate cooling and control of large area of global surface temperatures. This global system is made of arrays of multiple sub-systems that monitor climate and act locally on weather with dynamically generated local forcing & perturbations for guiding in a controlled manner aim at long-term modifications. The machineries are part of a large-scale system consisting of an array of many such machines put across the globe at locations called the control stations. These are then used in a coordinated manner to modify large area weather and the global climate as desired.

  • Publication number: 20230179002
    Abstract: A system for dynamically balancing power in a battery pack during charging and discharging includes a battery pack, a control unit, and a load unit. The battery pack includes one or more modules. Each module includes one or more bricks. Each brick includes one or more blocks connected either in a series configuration or in a parallel configuration. Each block includes one or more cells. The control unit is connected with the battery pack across each of the blocks for processing power from each of the blocks irrespective of a power mismatch between the blocks. The control unit dynamically balances the power in the battery pack by controlling a differential current from a block with higher state of charge (SOC) to a block of lower SOC, using one or more converters and thereby maximizing available energy of the battery pack during charging and discharging.
