  • Patent number: 10777960
    Abstract: A laser for high power applications. The laser is a lamp driven slab design with a face to face beam propagation scheme and an end reflection that redirects the amplified radiation back out the same input surface. Also presented is a side to side larger amplifier configuration, permitting very high average and peak powers due to the electrical efficiency of absorbing energy into the crystal, optical extraction efficiency, and scalability of device architecture. Cavity filters adjacent to pump lamps convert the unusable UV portion of the pump lamp spectrum into light in the absorption band of the slab laser thereby increasing the overall pump efficiency. The angle of the end reflecting surface is changed to cause the exit beam to be at a different angle than the inlet beam, thereby eliminating the costly need to separate the beams external to the laser with the subsequent loss of power.

  • Patent number: 10227918
    Abstract: A Polygon Oscillating Piston Engine having multiple pistons on one of two oscillating disks. Each piston moves in a straight line along one of the sides of a polygon within a cylindrical chamber, while the oscillating disks move in an arc about a central shaft. The difference in the straight motion of the piston and angular motion of the oscillating disk is accommodated by a slip sleeve within the piston that slides on a peg or bar mounted to each disk. The engine can be configured to operate as an internal combustion engine that uses diesel fuel, gasoline, or natural gas, or it can be configured as an expander to convert high pressure high temperature gas to rotary power. This engines compact design results in a high power-to-weight ratio.

  • Publication number: 20180087454
    Abstract: An engine configuration that uses multiple opposing piston pairs to form respective expansion chambers for expanding a gas within to move the pistons to drive a main shaft. The engine can be configured to operate as an internal combustion engine that uses diesel fuel, gasoline, or natural gas, or it can be configured as an expander to convert high pressure high temperature gas to rotary power. The pistons may be mounted on the circumference of one or more disks. For any given set of choices of numbers of pistons and sizes of pistons, disks, and gears, there are disclosed dimensional constraints useful for more efficient functioning of the engine. This engine can be provided with a compact design which results in high power to weight ratios.

  • Patent number: 9869272
    Abstract: A Rankine Expander System that converts low quality heat (heat usually at temperatures below 400 degrees Celsius) to electricity by using the properties of trans-critical CO2. The system is comprised of a compressor, an expander, three heat exchangers, and a permanent magnet alternator (PMA). It operates at pressures and temperatures that hold the CO2 above its critical point for the full cycle, and as such, attains high efficiencies even at low power. Under some conditions the efficiency can exceed 50%.

  • Publication number: 20170190647
    Abstract: A Plasma Arc Reformer for creating a useful fuel, such as Methanol, using any of Methane, Municipal Solid Waste, farm or forest waste, coal orchar rock from oil shale production, petrochemical hydrocarbons, (any carbon containing charge), water, and/or Municipal Sewage, as the source material. A High temperature Plasma Arc de-polymerizes the source material into atoms which, upon partial cooling, creates a gas stream rich in CO and H2 (syngas). Subsequent molecular filter and catalyst stages in the system remove contaminants and produce the output fuel. The system is closed loop with regard to the syngas production in that it recycles the residual unconverted gas and even the exhaust gases if desired. The large amount of heat produced is captured and converted to electric power using a supercritical CO2 Rankin cycle resulting in potentially high efficiencies.

  • Publication number: 20170070022
    Abstract: A slab laser and its method of use for high power applications including the manufacture of semiconductors and deposition of diamond and/or diamond-like-carbon layers, among other materials.

A side-to-side amplifier configuration permitting very high average and peak powers having scalability is also disclosed. Cavity filters adjacent to pump lamps convert the normally unusable UV portion of the pump lamp spectrum into light in the absorption band of the slab laser, thereby increasing the overall pump efficiency.
