This Small Business Innovation Research (SBIR) Phase I project investigates the merit of a novel capacitive generator design for use in the wind energy sector. The general design utilizes electric fields to exert forces on mechanical systems, a concept that is routine on the Microelectromechanical Systems (MEMS) scale but is nonexistent at the macro scale common to most industrial power applications. The technology is synthesized from a multidisciplinary approach of electrical, mechanical and chemical components which provides a novel approach for wind turbines, electric motors, and generators, yet which is theoretically capable of higher sheer stress and lower power loss than any currently available machine. In this project, these various components and the resulting machine will be prototyped, tested, and evaluated against competing, current state-of-the-art wind turbine generator technology.The broader impact/commercial potential of this project is to decrease the levelized cost of energy for wind power generation compared to fossil fuels and current methods of wind power generation, while simultaneously enabling a suite of fundamentally new types of motors, generators and actuators for use in global industry. Commercially, the technology resulting from this project will offer a lower cost of torque in a smaller and lighter unit than competing technologies by leveraging electrostatic versus electromagnetic forces. Furthermore, the inherent high torque capability increases system reliability by eliminating gearboxes and their maintenance. Wind energy is a large, global, and high-growth industry, particularly in the ?large wind? market segment (100 kW). Under the increasing pressures of climatic change, demand for and investment in renewable energies such as wind will continue to increase. Additionally, wind power is most commonly farmed in rural areas; therefore it offers new revenue streams for rural populations and increased investment in rural areas while minimizing detrimental ecological impacts. From a technical perspective, the proposed capacitive machinery is naturally high-torque and low-speed, making it ideal for direct drive applications outside of wind as well, namely as a prime mover for large pumping, drilling, or mining installations.

这个小型企业创新研究(SBIR)第一阶段项目调查了一种用于风能领域的新型电容式发电机设计的优点。一般设计利用电场对机械系统施加力，这一概念在微电子机械系统(MEMS)规模上是常规的，但在大多数工业电源应用中并不存在。该技术综合了电气、机械和化学部件的多学科方法，为风力涡轮机、电机和发电机提供了一种新的方法，但理论上能够比任何现有的机器具有更高的切应力和更低的功率损耗。在这个项目中，这些不同的部件和所产生的机器将进行原型、测试和评估，对照竞争对手当前最先进的风力涡轮机发电机技术。该项目的更广泛的影响/商业潜力是降低风力发电的能源成本，与化石燃料和当前的风力发电方法相比，同时实现一套用于全球工业的根本新型电机、发电机和执行器。在商业上，该项目产生的技术将通过利用静电和电磁力，在更小、更轻的单元中提供比竞争技术更低的扭矩成本。此外，固有的高扭矩能力通过取消变速箱及其维护提高了系统的可靠性。风能是一个巨大的、全球性的、高增长的产业，尤其是在大型风能领域。细分市场(100千瓦)。在气候变化压力越来越大的情况下，对风能等可再生能源的需求和投资将继续增加。此外，风力发电最常在农村地区种植；因此，它为农村人口提供了新的收入来源，并增加了对农村地区的投资，同时将有害的生态影响降至最低。从技术角度来看，拟议的电容式机械具有自然的高扭矩和低速特性，因此非常适合风力以外的直接驱动应用，即作为大型抽水、钻井或采矿设备的原动机。
