    I can relate to that. I loved the sound of a friend's even-firing Triumph Bonneville (until the unsurpassed Lucas-based wiring set it on fire).
    Leaning it over to the limit however was not too spectacular, as the limit was about five degrees from the vertical. Nice sparks though.

    Ah, but I never had a Triumph, mine was a Norton Dominator 99 - much better handling than a Triumph! and definitely a step up from my little 250 Suzuki (which I also loved) - despite the shitty handling my little Suzuki could thrash a lot of them on our short street circuits, however, I tended to fall off when leading! (in fact I excelled at it)!

    Yes the sound of an even firing twin like all the British big twins, BMW etc. did sound quite pleasant, - even the old Bradford vans, 2cv's etc sounded fine too!
    Then again, I did like the sound of the 180deg parallel twin Hondas with their distinctive sound, while not as pleasant did get my blood racing too, - especially the 125 racers.
    Four strokes do have good qualities too, (some)!

    This thread needs another 'kick in the ass' (or is it 'arse') - all probably due to the Ryger sensation in ESE - I sure hope that the Ryger doesn't also end up in this thread as an 'oddball prototype'!

    On the foundry thread there was mention of Hydrogen being used as a fuel and Flettner seems to be interested in that, but it is a vast subject and could probably be talked about here (as this thread is not under the "Bucket" umbrella), and maybe leave more room on the other thread for actual projects which are ongoing ( I don't want to hijack that other thread of course ie "The Bucket Foundry").

    I remember getting some plans for 'on car' hydrogen generators about 10 years ago, which seem to be lost at the moment - this could possibly eliminate some of the problems (and dangers) associated with storing compressed hydrogen.

    We had a guy here in NZ called Archie Blue (from Nelson - or was it ChCh?) who actually made it all work but sold his ideas to a big company - of course they were filed away and never used! (don't think it was a hoax, it seems to have actually worked on his old Morris 1100) - unless someone here knows different!

    I think that at least some of his ideas are now available ie if you know where to look. and I believe that there are a few ideas around which have been built on Archie's lead - no doubt someone will know and no doubt some more info will come to light!

    My thoughts exactly: http://www.kiwibiker.co.nz/forums/sh...post1130870009

    I liked the read, Will. But extracting hydrogen from water? Sure, it can be done but I find it difficult to imagine that extracting it will cost less energy than can be generated by burning it again (I use the word burning here in its broadest sense, which includes oxidizing it in a fuel cell).

    The latest idea seems to be using ammonia (NH3) as a hydrogen carrier. It's still a gas, but not nearly as fuzzy about temperature and pressure as hydrogen. And unlike hydrocarbons it is inflammable.

    Yes Frits,
    It's like the perpetual motion thing, it intrigues people and keeps them occupied - the thought must have been put there to keep them from planning crime, wars etc!

    Not an easy thing to do in the sense that the gains don't seem to outweigh the losses quite enough.
    Your idea about using hydrocarbons to produce hydrogen for use in fuel cells is a good idea - electric motors are the way to go I reckon, in which case, I wouldn't be too happy if I happened to be a gearbox manufacturer.

    Then of course the whole thing is weighed down by conspiracy theorists and other neurotics, but even if all the stories about the oil companies were true, I have often thought that if everything suddenly changed, it would set the whole world economic system on its ear and the world would be in chaos!

    I haven't been studying it much of late but a more stable carrier like ammonia might be an an answer but have you ever had a decent whiff of ammonia? I have, from a nitriding plant and it wasn't funny!
    I think that the hydrogen fuel thing stands more of a chance than perpetual motion, but I would rather spend my time trying to solve these problems than doing things like the Rubik Cube or Chinese puzzles!

    I'll do you one better - a lot better. I survived a sniff of home-made Cl2 - just. Ammonia stinks; chlorine kills if you're a bit less lucky than I was.

    Yes, just takes one slip to remove us from this earth forever (can't reset, as the younger generation tends to believe!).

    What are you on about, now W-D?

    AFAIR, all who have left the Earth have returned again ( albeit, for sure, some were toast)..

    Belief aint got nothin' to do with it..

    Back on subject though..
    - I do note that a group of young NASA engineers have recently resurrected one of those mighty moon rocket Saturn V/F1 mills..

    Not really.
    What You see in the two links are just phantasies.
    But the thinking gave a nice feeling just like riding my MZ and by far not so dangerous.
    Wife and kids apreciated that.

    But the two Honda generators tied together wasn't a fantasy!

    Did you, or your friend, try to adjust the timing of the exhaust?

    The Honda twin was just made to test if one combustion chamber seing two schnuerle scavenged AC generators would cooperate without mechanical connection between cranks.It was not uniflow scavenged so changin exhaust timing would have served no purpose.
    My three friends did not believe it would be able to start unaided and made a toothed belt that fell off when a handle was released.I was not there and they tried it and it ran nicely and hard first time.They used a hairdryer as electrical load.I came over next day and accidently cut the belt and we then decided to try without.The generators were 8 poles and could lock on each other in 4 positions 90 degree appart.First try was the lucky one and it ran for 20 seconds or so with the hairdryer on and of.The lady of the house came down and said that her shirts would smell off cheap two stroke.
    It never ran again and when my wife died it was thrown out.Being a genius was not really important anymore.

    Niels, I'm very sorry to hear about your wife.

    Was that engine configuration unique? I didn't see opposed piston schnuerle before!

    Thank You.

    It was unique and affordable .
    Its real claim to fame was being worlds first AC synchronized twin crank opposed piston engine.
    I have some better pictures somewhere and will post links here.

    Next step would have been to make a real Junkers cylinder and test fuel consumption.
