A combination firepit and water fountain having a fountain base with an opening in a top surface of the base. A circumferential ignition coil is located within the opening and is connected by a fuel supply line to a source of gaseous fuel for providing a fire. A circumferential flameproof enclosure surrounds the ignition coil in the top opening of the base. A fountain top is also located centrally within the top opening so that the flameproof enclosure surrounds and circumscribes the fountain top. A water pump located in the base supplies a water flow out the fountain top and down the sides thereof into the interior of the fountain base, where it is recirculated.

An all-purpose gas stove structure capable of increasing its air intake includes an all-purpose opening-covering case, an extended supporting frame, and at least one gas nozzle. The all-purpose opening-covering case includes an opening-covering case body for covering the heat source-receiving opening of a roasting/grilling device completely, and a gas controller with a gas operation unit for controlling the state of communication between gas input and output ends. The extended supporting frame is a box with a protective lid, is coupled to the inner side of the opening-covering case body at one end, and has a stove burner opening at the opposite end. The lateral walls of the protective lid are formed with vent holes. The gas nozzle is provided on the inner side of the stove burner opening. The all-purpose gas stove structure allows a ceramic roasting/grilling device to have a higher air intake and therefore produce higher heat.

A method for operation of an industrial plant having an energy accumulator unit for production of synthetic natural gas, a power plant unit for production of electricity, an oxygen tank, a carbon dioxide tank and a water tank. In a first operation mode the energy accumulator unit is supplied with excessed electricity from the public grid to produce synthetic natural gas, wherein the produced synthetic natural gas is discharged in a gas network, while oxygen and water which are produced together with the synthetic natural gas are stored in the oxygen tank and the water tank correspondingly. In a second operation mode gas from the gas network together with oxygen from the oxygen tank and water from the water tank are used in the power plant unit to produce electricity, which is supplied to the public grid. This way electricity production excess is efficiently accumulated for industrial or municipal use.

The present invention provides a multipurpose outdoor gas fire place having a frame with a gas outlet about its center and at least three adjustable radius arms for connecting to a gas canister housing, a gas line with an output control valve and a first end able to be securely connected to a gas canister through a pressure regulator and the second end able to be securely connected to a gas outlet and a cover-tray that fits over the gas outlet for burning gas. The arms have connectors on the ends for securing the frame to the gas canister housing that has an open top for receiving the cover-tray. The cover-tray distributes the gas about its middle and along its perimeter for burning gas and has a central adapter in line with the gas outlet for connecting a second gas burning element.

Various embodiments of the present disclosure provide a combustion-powered fastener driving tool fuel cell assembly including a fuel cell, fuel cell adapter, and fuel cell adapter cap for a combustion-powered fastener driving tool. The fuel cell, the fuel cell adapter, and the fuel cell adapter cap enable both the fuel cell adapter and the fuel cell adapter cap to be attached to a fuel cell and particularly a sealing member of the fuel cell in one efficient step. This single step process can be done manually or automatically, and is substantially more efficient and less time-consuming than the known fuel cell assemblies.
