Abstract: An apparatus is provided for producing sulfur from hydrogen sulfide. The apparatus includes a container containing a solution that includes hydrogen sulfide. Within the container, and at least partially submerged in the solution, is a photo-anode, formed of an N-type semiconductor, and a photo-cathode, formed of a P-type semiconductor. Each electrode is at least partially covered with a catalyst material. The photo-anode and photo-cathode are electrically coupled to each other and develop charges of opposite polarity when exposed to a light source, which causes the sulfur to separate from the hydrogen in the solution. Also provided is a method for producing sulfur from hydrogen sulfide.

Abstract: An apparatus for converting solid waste. The apparatus includes a container at least partially filled with a solution. A cathode and an anode are disposed in the container and at least partially submerged in the solution. The container further includes an oxygen supply and an opening in the container for receiving waste material into the solution near the anode. The anode and cathode are electrically coupled by an electrically conductive path. Oxygen molecules are reduced at the cathode whereby electrons are added to the oxygen molecules in the solution so that, together with H+ ions, water is formed. Electrons take part in the dissociation of the waste material in the solution and are accepted at the anode. In addition, chemical reactions on the electrode surface occur. The electrons then move to the cathode through the electrically conductive path, producing an electric current between the anode and cathode.

Abstract: A device for converting solid waste to gaseous form. The device includes a chamber for holding waste material and molten eutectics. The chamber has at least one opening for receiving the waste material into the molten eutectics. An oxygen supply and an ozone supply bring oxygen and ozone into the molten eutectics. The waste is heated by the molten eutectics and combines with the oxygen and ozone to form at least carbon dioxide, which can be removed for use, disposal, or storage. In one embodiment, a grate contains the solid material and prevents it from reaching a top surface of the molten eutectics and a blade mixes the eutectics, waste material, oxygen and ozone. Also provided is a method for converting solid waste to gaseous form.

Abstract: A conduit is arranged in a substantially vertical configuration and has an input and an output for passing a gas through the conduit interior. A catalyst material is present within the conduit. A heat source heats the conduit to a sufficiently high temperature so that the gas reacts with the catalyst and produces a byproduct and hydrogen gas. A vibrator or other mechanical device is coupled to the conduit and causes the carbon to detach from the conduit body. Also provided is a method for producing hydrogen gas.
