    Don't let him get away. Offer him a pot of gold and if that doesn't work, lock him in your basement. (have you got a basement?)

    Still looking, can't remember where I put that pot of gold.
    Its not in the box marked GOLD/POT so I guess its laying around the workshop somewhere. Or maybe its all gone up in smoke?
    Lock him in the basement? Thats a German thing isn't it, greasing his palms with cash I'm sure will do the trick.

    I think that's an Austrian trick

    does this link work?

    maybe I am intetested in sterling cycle engines, heat via a parbolic curve. This above CO2 to ethanol system, if it were to work, will need LOTS of (free) energy.

    Yes, working for me, and looks really interesting indeed (when I've checked it out properly) - sounds too good to be true, (next they'll be complaining that we are depriving the trees of Co2) causing deforestation

    Imagine racing around the treestumps in the Woodhill Desert! !

    yes Will, it does sound too good to be true and you know what they say.
    But if it were, I would like my solar energy stored in liquid form thankyou. I guess the conversion efficency will be dismal or some fish hook like that.

    I think the fish hook is a lack of torque and slow speed.
    Are you mean these

    All well and good but I don't think a sun dish would be all that useful in the Waikato, perhaps a rain dish? But what if?

    So are you meaning a true Stirling engine
    I would rather your next one be a gun power engine if you could harness the energy of gun powder in a proper reciprocating engine.
    Renewable just Sulphur charcoal and saltpetre I think you can even make it out of pig dung.

    Cow shit makes some pretty good gas - and from what I can remember of my days on Waikato farms, there is an abundance of that!

    There is probably quite a bit of energy going to waste in the form of the methane gas being given off which could be tapped into (if if we could be bothered to get off our arses and use it) just needs to be stored in the right place! - and doesn't need to be highly compressed I believe - excellent for Stirlings! ( or melting metal).

    And it's definitely green! - No bullshit! (bulldust to our Aussie mates)

    I think that there would be a few issues with blocked jets and just think if the exhausts got blocked with (pig dung?) and you had a backfire!!

    To get back to foundry stuff, has anybody here got any experience with microwave melting of metals? - my circumstances in future don't make it look good for a proper foundry (no space).
    I tried microwave melting a while back but it was a dismal failure and I put it away and didn't persevere - the problem may have been because the microwave I bought was not the 1100 watt it was said to be (not sure though, as it had no label on it), but it was cheap and it actually is a good kitchen microwave at the moment! .
    However it never did get the little clay graphite crucible to much more than to about 90 deg C.(it was packed around with carbon - charcoal in this case), maybe I should have used graphite? - but some people do manage to melt metal in microwaves, so where have I gone wrong?

    Will, you are right, this is a foundry site.
    But not much foundry stuff happening it seems.
    So in the interim I guess stuff gets talked about that could be cast or has been cast or is just bullshit.

    Myself, casting has ceased due to rain, rain and rain. And a broken crucible, again, expensive game. All set to cast some new cylinders but now have to wait for finance to catch up, bugger it.

    Is it possible or feasible to make one with say a SS with a ceramic coating.
