Abstract: A poop catching system and methods configured to removably hold a bag using at least one bag constrain; an extendable element configured to produce at least two position in the bag: opened and closed; such that in the opened position poop can enter into the bag and in the closed stop poop from exiting the bag; and a handle to allow the bag in the open position to be held underneath an animal while it is evacuating. Further aspects include that that the extendable element is a sliding plate and the poop catching system further comprises a fixed plate with mating geometry and in the closed position the sliding plate and fixed plate are flush to one another. Still a further aspect involves the at least one bag constraint configured being a gate type bag constraint.

Abstract: An apparatus and method of creating a high combustion rate in a combustor used to burn combustible matter. The combustor comprising a cylindrical combustion chamber extending vertically with at least one side loading bin for loading combustible matter into the combustion chamber while combustion is ongoing. The combustor creates a high combustion rate by inducing an acoustic excitation and an ascending vortex in hot gases that is reflected by a conical surface, converting the ascending vortex to a descending vortex. The shear between the ascending and descending vortices increases mixing. The descending vortex acts to separate the small, fully-combusted particles from larger particles that are thrown by centrifugal force back into the combustion zone.
