A heating system for heating at least one of a fluid-filled conduit arrangement and a volume of air includes an internal combustion engine provided with engine coolant that flows to and from the engine and is heated thereby. A fluid heat exchanger is provided in fluid communication with a heat transfer fluid stored in a reservoir and the engine coolant of the internal combustion engine. The fluid heat exchanger receives heated engine coolant from the internal combustion engine, and transfers heat from the heated engine coolant to the heat transfer fluid to provide heated transfer fluid. A heat generator is provided in fluid communication with the fluid heat exchanger, and receives the heated transfer fluid from the fluid heat exchanger for further heating. This heated transfer fluid may then be selectively used to heat a conduit or a volume of air.

A water purification system with a centrifugal system and a frictional heating system consists of a centrifugal unit, a cavitation unit, a cooling condenser, a vertical shaft, and a pitot tube. The centrifugal unit and the cavitation unit are mounted along the vertical shaft so that the rotational movement of the vertical shaft is transferred onto the centrifugal unit and the cavitation unit. Non-potable water is directed into the centrifugal unit to separate heavy solids. Less populated water from the centrifugal unit is transferred to the cavitation unit via the pitot tube. The cavitation unit uses friction to generate phase change in the volume of less populated water which is then directed to the cooling condenser to produce potable water.

A system for flameless heating of a fluid includes a hydraulic pump having an input shaft and a rotational power source coupled in torque-transmitting relationship with the input shaft of the hydraulic pump. A hydraulic fluid circuit is in fluid connection with an inlet port and an outlet port of the hydraulic pump. A water heat exchanger having a tank provided with water from a water source and a conduit provided with heated fluid from at least one of the hydraulic pump and the power source is arranged such that heat is transferred from the heated fluid in the conduit to the water in the tank. In one example, at least one valve in the hydraulic fluid circuit selectively limits output flow from the outlet port of the hydraulic pump, thereby providing resistance to pumping motion and heating the hydraulic fluid in the hydraulic pump.

A cavitation engine configured to produce superheat steam from injected liquid water. The cavitation engine includes a funnel shaped impact chamber having an impact surface having a temperature of at least 375 degrees Fahrenheit, a small diameter opening at a bottom of the impact chamber, and an expansion chamber below the small diameter opening. The engine includes a fluid injector having an outlet positioned adjacent a largest diameter of the impact chamber and located to inject hyperbaric liquid water onto the impact surface of the impact chamber at supersonic velocities such that cavitation bubbles are present in the injected water. The outlet of the fluid injector and the impact surface are located relative to one another such that the outlet is spaced a distance from the impact surface of between 0.150 and 0.450 inches and the injected water hits the impact surface at an angle of between 85 and 95 degrees. Impact of the water with the impact surface crushes the cavitation bubbles in the injected water to generate pressure above 1,000 pounds per square inch and produce superheated steam.

An endoscope defogging and pre-heating device includes a bag including a first seal line and first and second chambers defined at an opposite lateral sides relative to the first seal line, a heat storage/release material flowing between the first chamber and the second chamber for storing/releasing heat energy, a fixation device for securing the bag in a folded status to hold the endoscope to be pre-heated between the first and second chambers, and an actuator bendable to generate oscillation waves for causing the heat storage/release material to produce a temperature rise and then to release heat for pre-heating the loaded endoscope to about 98 F.138 F.

A dual heating process is performed in the absence of an open flame. Heat is created by a rotating prime mover(s) driving a fluid shear heater. Heat is also collected from a cooling system of the prime mover, and from any exhaust heat generated by the prime mover. The heat energy collected from all of these sources is transmitted through heat exchangers to a fluid where heat energy is desired. The fluid being heated may be glycol or air, depending on the type of heat desired.

A system for heating a structure uses a cavitation engine connected to a water supply, and to a discharge pipe, a condensate storage tank connected to the discharge pipe, the storage tank collecting condensate from the discharge pipe, and a pump connected to the condensate storage tank via a transfer pipe and being configured to pump the condensate out of the storage tank, and ether directly back into the cavitation engine for reuse or into a mixing tank for mixing with water from the water supply, and then back to the cavitation engine. The system creates a closed loop so that no water is wasted, and the energy generation is as efficient as possible.
