A wind turbine blade system having a main blade having a root and a tip, and at least one secondary blade secured to or formed integrally with the main blade about the tip, the at least one secondary blade being shaped and dimensioned to form, when the main blade is rotated, a shroud circumscribing a swept area of the main blade in order to improve the airflow past the main blade during operation of the wind turbine.

A control system for controlling the operation of a Downhole Steam Generator (DHSG) system includes a cascade control strategy for control of individual final control elements in communication with a local well master controller. The final control elements may control fuel, oxidant, feedwater, and/or carbon dioxide flow to the downhole steam generator. The local well master controller may monitor and adjust the flows to the DHSG to control the operating performance of the DHSG.

A system and method of measuring and controlling the operation of a downhole steam generator. The system may include surface and/or downhole control systems for sending and/or receiving control and measurement signals. The control systems may also communicate with and control surface and/or downhole equipment for supplying process fluids, gasses, and/or mixtures to the downhole steam generator. The control system may control operation of the downhole steam generator by storing, processing, and/or analyzing measured data corresponding to one or more downhole steam generator operations and/or one or more field, formation, reservoir, or other operating objective.
