Abstract: A lighter is provided comprising an ignitable material for igniting when heated defining a recess along a length thereof. The lighter further includes a striker material for effectuating sparks when struck defining a protrusion along a distance thereof. The protrusion is shaped to be slidingly engaged with the recess for selectively securing the striker material to the ignitable material. Additionally the lighter includes a combustible handle including lignocellulosic material or polymer material for igniting when heated, the handle defining a cavity that selectively receives the striker material and the ignitable material when engaged.

Abstract: An electrical energy generation system includes an electricity generator assembly from which a tensile line extends. The electricity generator assembly is configured to retract the tensile line and generate electricity upon extension of the tensile line. A vented airfoil assembly is attached to the tensile line. The vented airfoil assembly includes an airfoil through which at least one or more vent holes are defined. Each vent hole is entirely surrounded in surface perspective by the airfoil. A vent assembly is positioned in each vent hole. Each vent assembly has an open configuration in which the vent assembly permits airflow through the airfoil and a closed configuration in which the vent assembly restricts airflow through the airfoil. Each vent assembly is controllable such that the vented airfoil assembly constitutes a maneuverable kite.

Abstract: There is disclosed a safety tire for motor vehicles which is comprised of a cord-reinforced body having a pair of generally radially extending outer sidewalls and a third center wall. The three walls terminate in inextensible tire beads which are adapted to seat on a rim and to form therewith two side-by-side, axially arranged, airtight chambers. The rim has two axially outer bead seats, and an axially inner bead seat formed by flanges each curving toward a respective tire chamber.
