Abstract
In a preferred embodiment, an umbrella has a reflective concave face serving a radiant energy collector when the umbrella is invertedly mounted, and a clamp clamps onto the umbrellas shaft a vessel containing water partially filling the same, the vessel being of narrow thickness and being supported at a point of converging reflected rays of energy, the vessel having upper steam space connected to a heating-vessel for heating typically a cup of coffee by heat-exchange with the coffee cup, and having a drain conduit for draining condensed steam back to the liquid-containing vessel, a steam conduit channeling steam through a liquid trap for removing water droplets carried by the steam, and the umbrella when upright serving as typically a beach umbrella which shifts with the wind by virtue of the shaft being off-set from the center.
