It never went into production because a proper production model was never produced, the prototype never demonstrably ran under load, and had major technical issues/downfalls. Also, BHP poured money into the engine long before it ever got close to being a production model - initial invention and investment was in the early '70s, the technology failed to deliver and by the 90's BHP had actually DIVESTED themselves - ie they got OUT of the investment. They didn't buy the patent and squash it, they wiped their hands of it, because they knew there was no money in it. So many conspiracy theorists/paranoid people out there that think every failed invention has been squashed by either "the man" or "big oil". Excuse me? Are you saying "big oil" would not quash anything that infringed on their massive profits? I'm sorry man... youre living in fairy tale land if you think they wouldnt.. Every business no matter what line of product, will try and outdo the competition.. Big Oil is no different.. in fact they are much, much worse. There is a way to run a car on Hydrogen, converted from Water. Check out this Youtube Video before you say BS.. watch ALL of it. http://www.youtube.c...77AB90EB0750C0C
