Latest Patents

One of Stewart's latest patents is an energy conversion system that utilizes an efficient split cycle solar energy conversion method. This innovative system employs sensible heat storage to isolate a solar receiver loop from a Brayton cycle engine loop. The process begins with charging a sensible heat storage unit via the solar receiver. This unit is then switched to the inlet of the Brayton cycle turbine, where it discharges its stored energy. The system can achieve an overall thermal/electric conversion efficiency exceeding 60%. Additionally, the Brayton cycle engine can operate with a sensible heat storage unit charged from fuel-fired sources, allowing it to utilize 'dirty' fuels without damaging the turbine blades.

Another significant invention by Stewart is a harnessing device featuring a locking head and an attached serrated strap with gripper rails. This device is designed to encircle and secure items effectively. The head includes a guide channel for the strap and an internal locking tang. The serrated strap is equipped with side rails that grip the encircled items, enhancing the gripping action through the inclusion of serrations on the rails.
