A non-ceramic, light-weight outdoor cooker made from formed sheet metal includes a double-walled kettle, with an inner wall spaced and insulated from an outer wall by an insulating layer. A domed lid is constructed similarly to the double-walled kettle and is hinged to the top of the kettle. By spacing the inner wall from the outer wall and providing an insulating layer, heat transfer to the outside of the cooker is greatly slowed. By constructing the structure of sheet metal, instead of ceramic, the cooker is light-weight, rugged, and economical to manufacture.

A rotary platform is provided for the harvest of specialty crops such as grass seed.

A load control system, in certain aspects, may be configured to decrease the amount of noise pollution of a prime mover (e.g., engine) of a service pack in that it may not require the prime mover to operate at higher discrete operating speeds to deliver small amounts of air from the air compressor. The load control system may also only increase the speed of the prime mover to a minimum discrete speed required, keeping noise at a minimum. The load control system may also maximize fuel efficiency by not operating the prime mover at the highest discrete speed at all times. More specifically, the lower operating speeds may lead to less fuel consumption.

A thermodynamic pressure generator having an oscillating valve that allows premixed fuel to enter a combustion chamber in turbulence, until it comes into contact with an annular spoiler, which converts a portion of the fuel into a Karmon vortex ring for delayed ignition. A continuous spark then ignites the remaining fuel with rapid pressure rise that kills the vortex. The fuel in the vortex goes from laminar to turbulence, adding fuel to the already burning charge, super charging it and permitting total ignition.

Exhaust gases are released radially through turbine vanes having a shape that permits a relatively low rotational speed, with sufficient peripheral speed to create torque of considerable degree. Applications include, but are not limited to, land transportation vehicles, propeller-driven airplanes, and marine vessels.
