The nozzle you see above is part of the Safeflame, a blowtorch device that splits water in oxygen and hydrogen before recombining them both outside of the torch's mouth in order to create fire (using water!)

This method has existed for awhile, but was previously considered too pricey for wide adoption. Andrew Ellis, one of the Safeflame researchers, says they've finally managed to make it a lot cheaper and also safer than traditional propane and acetylene torches:
...the new system has been "developed to use a standard mains electricity supply, and water. The water is split into hydrogen and oxygen gases and fed into a torch where a flame is produced, which can then be used for brazing or any other industrial application where flame is used. So it's just using water to make a flame, basically."
Even more amazing is that the torch remains cold to the touch at all times, which means users can put it down anywhere they want without worrying about singing themselves.
