Abstract: A fuel tank assembly includes a fuel tank including a fuel inlet. A fuel cap is threadably engageable with the fuel inlet. The fuel cap has a grip provided for manipulation by a user. A vent path extends between a vent channel and the interior of the fuel tank. In a first configuration, the fuel cap is fully threaded to the fuel inlet to a fully closed position. The assembly is operable to transition to a second configuration in which the vent path is unobstructed and the fuel cap is fully threaded to the fuel inlet to the fully closed position. To enable unthreading of the fuel cap from the fuel inlet, the fuel tank assembly is operable to transition from the first configuration to the second configuration in response to a movement that does not alter the threaded engagement with the fuel inlet.

Abstract: High efficiency conversion of heat energy to electrical energy is achieved using a ring of metallic components and anodically sliced, reduced barriers, high purity n-type and p-type semiconductor wafers. Energy produced by heating one set of fins and cooling another set is extracted from a ring of bismuth telluride based n-type wafers and antimony telluride based p-type wafers using make-before-break control of MOSfet switch banks. Standard AC frequencies and DC output result from rectification of make-before-break high frequency switched very high currents in the ring and a DC to AC converter. Solar energy stored in porcelain fragments extends the time that solar energy can be used as the heat source for the thermoelectric generator device.
