Systems and methods for a multimode propulsion system (MMPS) are presented. The MMPS includes a chemical thruster, an electric thruster, and a shared propellant tank. The MMPS further includes a propellant decomposition chamber that transforms, via a catalytic and/or electrolytic process, the propellant from the tank into vapor form for use as gas propellant by the electric thruster. The electric thruster can be configured for targeted ionization of one or more constituent species present in the vapor form of the propellant. Flow activation/control from the tank to the chemical and electric thrusters is provided by a fluidic feed system. The branches include a check valve and a pressure regulator in series connection. A normally closed squib valve prevents propellant flows/leaks from the tank to either the chemical or the electric thrusters when the MMPS is not in operation.

The invention provides a plasma production and control device that may be used in propulsion (e.g., satellite propulsion) and/or industrial applications. The plasma production system comprises a unidirectional magnetic field.

The golf club cover is a cover adapted for use with golf clubs. The golf club cover is designed to protect both the head and the shaft of the golf club. In order to more appropriately pad and protect the shaft, the golf club cover opens into two segments that can be wrapped around the head of the club and wrapped tightly around the shaft of the club. Once properly placed on the golf club, the golf club cover is held in position using a plurality of magnets. The golf club cover comprises a head piece, an elastic band, and a shaft padding.
