Yet another dubious alternative power source – this has been a good year for them so far. The latest arrival is a variation on the old ‘splitting water into hydrogen and oxygen and using them for combustion’ idea, allegedly from a company called Xogen. My skepticism is somewhat enhanced by the fact the the link to their ‘corporate site’ actually leads to a domain that’s up for sale. Obviously I’d be overjoyed to be proved wrong, but I’m confident I won’t be, at least not this century.
