    What are we talking about...

    Yes, saw this recently. What may be the biggest game changer may be the sodium ion battery production. These don't burn, and don't need excessive amounts of controversial minerals.

    Dafuq 😯 Looks like someone is going to be an ex pilot. Much better than there being ex people though

    It could be worse. They might instead remove all mention of any of them, and go on to redact any mention of Enola Gay, because gay is 'woke' 🙄

    Agreed. Boonah has plenty of fields around it, but results may vary with emergency landings 😄 As long as you are within gliding distance you can easily keep out of any traffics way. After a few basic tests, which we have done it would be very safe to fly say five to ten miles away. All academic at the moment, all these public holidays have their downside as I can't get my guy to fly for a while.

    The aircraft has to be test flown around the airfield it's based at. Im mostly bummed about the fact I probably won't get to test fly my own aircraft on my own and I'll have to wait for the remaining 23 hours.

    This in fact is my next step if all else fails. I haven't asked yet but there's a guy who lives nearby who might be able to help. He's built a few aircraft and finished incomplete projects so would be easy to get him on the test schedule.

    I forgot to mention that we applied with both our names. But Ra Aus knocked me back due to my lack of recent flying hours. Which I guess is fair enough .Otherwise I wouldn't even consider selling it until I finished off the test flying.

    *THINKING OUT LOUD EDITION* As per heading, my plane only has about 3 hours of test flying on it. I'm not on the test flight schedule unfortunately. My guy at the airfield is on the paperwork. I haven't talked to him yet, but I do know he's not interested in doing all 25 hours himself. Has anyone been in a situation like this? What are the pros and cons? I'm guessing a big con would sale price.

    While I'm sure there must be some corruption in China, the perpetrators have to really be in the know, as they have the death penalty for such things there. But other Asian countries...

    So get a boilermaker.

    What is this a reply to?

    I think the idea is you want it to be quite high pressure, and lots of it, so heat is in the mix there. Possibly running through a 'radiator', which in this case is absorbing heat from the air.

    You've compelled me to look it up. Seems it's a variation on a compressed air motor, but using liquid nitrogen that is heated to become pressurised gas https://en.wikipedia.org/wiki/Liquid_nitrogen_engine As far as I can tell, this is the only car to have used a liquid nitrogen engine

    Of course if you miss out on nitrous oxide, it's no laughing matter 😀
  17. danny_galaga
    And of course potassium nitrate if ya wanna get a rocket up ya 😀
  18. danny_galaga
    I forgot to mention trinitrotoluene. Plenty of bang for the buck 😀
  19. danny_galaga
    How about ammonium nitrate? That'll give you a hurry up!
  20. danny_galaga
    Unfortunately there's a two way loss that is hard to get around - compressing the air generates lots of heat. Decompressing it, eg driving a piston engine, absorbs lots of heat, potentially freezing up the engine. This was definitely a problem with the model CO2 motors I used. You would actually get ice on the pipes!

    In fact, I think it was Peugeot that was experimenting with compressed air for a hybrid. Compressing air during braking. I was very excited about the idea, because it's much simpler than batteries. Unfortunately, as you say, huge inefficiencies compressing the air. They dropped the idea.
  22. danny_galaga
    I guess they were thinking of ammonia when they typed it?
  23. danny_galaga
    Doesn't seem like they were in a circuit though.

    I still shrug in your general direction 🤷‍♂️ 😄
