Power Chips plc has devised "Power Chips" which generate electricity by using heat to move electrons from one side of a vacuum diode to the other. The system, currently under development, contains no moving parts or motors and can be either miniaturized or scaled to very large sizes for use in a variety of applications. Whether it is to recover energy from the waste heat of traditional engines and turbines, or to replace them completely with a compact and efficient solid-state system, Power Chips present product engineers and project managers with a broad array of design options.
