Abstract: A fuel cell system employing a reformer for developing a fuel process gas from a hydrocarbon fuel-water mixture wherein the mixture is generated by exclusively delivering a water miscible hydrocarbon fuel to a mixing tank when the level of constituents in the mixing tank falls below a first predetermined level, ceasing delivery of the fuel and initiating exclusive delivery of water to the mixing tank when the level of constituents in the mixing tank rises to a second predetermined level, ceasing delivery of water when the constituents in the mixing tank rise to a third predetermined level, with the level in the mixing tank at the third predetermined level, delivering the hydrocarbon fuel-water mixture to a holding tank when the hydrocarbon fuel-water mixture in the holding tank falls below a first predetermined position, and ceasing delivery of the mixture to the holding tank when the level of constituents in the mixing tank falls below said first predetermined level.

Abstract: An elevated and elongated boom is centrally pivoted for rocking movement in a vertical plane through the horizontal plane. Provision is made to align such plane with the direction of the wind. A pair of free wings are mounted on the fore and aft ends of the boom with control panels being oscullatably mounted on such wings for determining by their relative positions and aerodynamic equilibrium reaction thereto the angle of attack of such wings.
