For what it's worth guys,i have an old(78)year old German engineer living next door,over the last few years he had been working on a hydrogen/petrol powered late 70's Mercedes Benz.Now doing what i do he was constantly keeping me up dated on his progress and showing me his handywork.I have to admit it all meant nothing to me and i did'nt understand what i was looking at as i;ve never seen so many one way valves relays etc.etc.etc. but i have seen this thing running and was amazed.
The sad part of all this is that the authorities quite recently got wind of what was going on in his shed when he tried to re register the old girl as a daily driver,and was threatened with all manner of grief unless the system was dismantled and disposed of in a manner suitable to our local Glovemit agency for fear of taking out our suburb in a catastrophic armageddon event!!

I guess i would'nt have known much about it had it gone,but it does beg the question about the politics of it all...After all they said Felix Wankel was a fool,Ralph Sarich,Henry Ford,the Wright Bros.the list goes on and on,i think it's called protection.
