Abstract: Tracking modules are effectively provided that can be arranged as systems for positioning devices, such as reflectors. A preferred reflector is small and light in comparison to prior art reflectors so that components can be utilized within reflector construction and support structure that are sufficiently stiff to accurately hold a reflector in place under expected operational drive-torque, gravity and wind loads. At the same time, a single person can install a reflector, easily overcoming a retention mechanism spring force so as to positively engage a reflector in position. This is achieved without the need for any tools, through a combination of a retention mechanism and a spring feature design. Arrangements of tracking modules are included for easier manufacture, transport of systems and installment.

A deaerator is fluidly coupled to receive condensate from the hypersonic energy harvester.

Abstract: The detonation propagation in a channel geometry which suppresses detonation propagation in one direction, allows it in another direction, and does not create flow restrictions in the channel. The geometry consists of a series of divergent sections separated by wedges that form a sawtooth shape. The detonation fails to propagate through this geometry in one direction because the detonation front is weakened by diffraction, and reignition centers are isolated from the main channel. In an opposite direction, convergent parts of the geometry support the detonation propagation, because subsequent shock collisions with oblique walls that form convergent sections create powerful transverse waves. These powerful transverse waves help the detonation propagation or reignite it.

Abstract: A flameless heater produces hot dry air utilizing hydraulic heat-transfer fluid as a heat transfer medium. The heater is powered preferably by a natural gas engine. The process begins with the natural gas engine producing rotary power which drives a hydraulic pump which directs the heat-transferring fluid through a dynamic heat generator to heat the fluid via an internal friction process. The heated fluid is subsequently circulated through a heat exchanger where a hydraulically-powered fan blows ambient air through to be heated. The heat exchanger also extracts heat from the exhaust and coolant system portions of the engine to further heat the air. The produced dry hot air may be used for general heating. It is envisioned that engines which utilize other fuel sources such as diesel, gasoline, steam, or the like could be utilized with equal effectiveness.
