    Abstract: A stove top barbeque may be used with common stoves to provide grilled cooking results. The stove top barbeque includes a base, a lid, and a grate for supporting food. The base includes lower flutes for catching liquids, and inverted upper flutes above the lower flutes to guide the liquids into the lower flutes. The lower flutes are staggered upwards from the middle pair outwards to distribute to distribute the flame below more evenly. This configuration allows for direct flame-grilling of food placed on the grate. The upper and lower flutes have a gradual slope to carry liquids to a trough along the front of the stove top barbeque. The grate lifts off for cleaning. The lid has an open position and a closed position over the base and is removable by lifting from the base. A catch holds the lid open in a nearly vertical position to drain condensation.

    Abstract: A solar receiver for exposing heat absorbing particles to concentrated solar radiation. The solar receiver includes a chamber having an aperture through which concentrated solar radiation can be received within the chamber. An inlet means provides for introducing an inflow including solar absorbing particles into the chamber. An outlet means provides for discharge of an outflow from the chamber. The inlet means communicates with the chamber for introduction of the inflow into a first section of the chamber in opposed relation the aperture. The outlet means communicates with a second section of the chamber disposed between the first section and the aperture, wherein fluid flow from the inlet means to the outlet means is exposed to concentrated solar radiation received within the chamber. The first section diverges in a direction towards the aperture, and the inlet means is configured to introduce the inflow tangentially into the divergent first section.
