A torch assembly for igniting a target fuel includes a torch including an elongate wand having a handle end and an opposing forward end, and a torch head located on the forward end of the wand. The torch head has a central axis. The torch head includes an outer surface, a fuel supply chamber, and a plurality of circumferentially spaced apart jet channels fluidly connecting the fuel supply chamber to the outer surface. Each jet channel is configured such that, when a pressurized flow of a gaseous torch fuel is supplied to the jet channels through the fuel supply chamber and ignited, each jet channel directs a respective flame jet forwardly and radially outwardly from the outer surface at an acute angle to the central axis.

A polymeric protective cover for a torch includes a thermal insulation surface layer for isolating the heat emitted, to protect a user from burns, and such protection for any belonging that may come into contact with the torch. The polymeric cover includes any or all of the following: (i) an open end, (ii) a closed end, (iii) an optional flexible strap, and (iv) a plurality of ridges on the inside and outside surface area. The heat and fire-resistant cover is shaped to fit securely on the torch barrel immediately after use of the tool so that its user may use it as a transportable, light-weight cover which may be used with the strap that circumvents the torch and secures to the polymeric cover. The aforementioned strap may also be attached to securely hold the torch barrel upright at various angles while in use by its user.

A portable electrolyzer includes an electrolyze chamber with an anode and a cathode as electrodes, a membrane, a water source, such as a water storage vessel, a gas tank, a gas compressor, an electric power supply, and a pulse-width modulator. The electrolyzer further includes i) a thermoelectric cooler attached to the electrolyze chamber and/or a gas tank, ii) an ultrasonic generator connected to at least one electrode and/or at least one sonotrode, and/or iii) a mixer capable of mixing the aqueous phase inside the electrolyze chamber. A process to generate and store hydrogen with the electrolyzer, the use of the electrolyzer e.g. for welding with a hydrogen flame, to convert electricity from renewable energies into hydrogen and to store said electricity in the form of hydrogen, and/or for heat generation by burning hydrogen in a porous burner are also disclosed. Furthermore, a blowtorch including the electrolyzer is disclosed.
