    They use to fire one up at the engine start up days at the aircraft museum in Port Adelaide. Not sure if they still do.

    Amazing aircraft!

    What facts. I didn't say what the last government did, i said I am sick of them blaming the last government Who cares what the last government did, Albo has been in for four years, new about the situation so he has dropped the ball. "BIG FAIL"He made a big deal out of it to score political points and has just proved he is no better then the rest. Here is the quote just so all you albo fans can read it. You can google the quote if you want to see it live. “The point of our international obligations is that Australia should have here 90 days available of liquid fuel reserves, so we are significantly in breach,” Mr Albanese said in the interview. “We shouldn’t be dependent upon circumstances which are which may be beyond our control, as you say, terms of any particular international incident, be it military conflict or other issues, will mean that we run out of fuel.”

    I must admit, I am sick of them blaming the last government. Albo made a point about the fuel security when he was in opposition so he new about it and has done nothing in 4 years so the ball is in his court. There is only so many times you can do that.

    You just insulted everyone you disagree with!

    Using Europe as a comparison to our fuel prices over here is like comparing apples and oranges. They have a very good public transport over there with a road that is bitumen also normally has a bus run along it. You can catch a train and prices being less than $100 between country capitals. Our fuel needs be cheaper once you get out of the metro area. Often it is not.

    Would not bother me at all, then I could walk to work. Spent fuel is political and public perception problem , not an engineering one. Thought this was an oddball aircraft thread.

    Yes- Micro reactors are coming and it is a no brainer. Being developed for remote community's and mines in Canada. The main problem is that they need their 20 years worth of fuel from new.

    I reckon, back in the day they use to put carb in a box and pressurise the box. The floats would have neded modifying.

    As I understand a Cessna 172 came out with 180 hp verses the 5.7 in the VY commodore was about 320hp. You could derate the commodore to 250hp and still be ahead. I would think the V8 would be slightly heavier and would need a redrive. Looks like the commercially redrives are fairly expensive. You wouldn't need to allow for stress of the slip the foot of the side of the clutch pedal on some good bitumen either.

    Tyre Pressure

    Siso posted a topic in Thruster

    Hi Everyone. Just wandering what tyre pressures everyone runs in their 2 seat Thrusters? What sort of tyres do you run? (tail dragger)
  18. Siso
    I reckon there was an australian drag engine manufacturer in the 80's that did the same thing. No head gaskets to blow. Were the early merlins the same?
  19. Siso
    Not bad for the early to mid 30's though

    Windfarms have underground cables and it is a regular occurrence, mainly at the joints. It has been suspected that as sometimes the cables are running flat out and than not carrying anything at other times the heating and cooling cycles cause the cables to grow and contract and the joints the weakest point. The cables had 3 phases in them and the joints heatshrunk? together. We ended up splitting up the cables for several metres at the joints and mounted each phase a metre or so apart to a frame underground. This seemed to fix the problem as we only had one failure in the last 6 or 7 years I was there. There a transmission lines in Australia that run up to 500kV. Portland Vic heading back towards the coal fired stations. 132, 275kV are the common ones.

    On a normal disc brake caliper the square section o'ring pulls the piston back because it twists a bit when the piston moves through it.

    Realistically to stop this we need to start putting some CEO's in prison (general population). We are told they get the big bucks because the buck stops with them. Qantas selling seats on cancelled flights, banks selling policy's to dead people, Woolies claiming specials on things at the standard price. These fines they are getting are budgeted for in the cost of doing business budget.

    heres one of them https://world-nuclear.org/information-library/nuclear-fuel-cycle/nuclear-waste/radioactive-waste-management , Its not had to fine plenty of sources. still waiting for the dirty bomb source!

    Madame Curie was around before they new what it was and safety practices weren't up to scratch. I would live next door to a power station in a heartbeat, more chance of getting run over by a truck than anything happening with a NPP, Source of information for making dirty bombs out of the long lived parts of the spent fuel please or is it from a movie(the peacemaker). X rays and gamma rays aren't the same thing. We work with stuff everyday that we should limit our exposure to. People get cancer from staying out in the sun too long. Easily researched from reliable sources on the net. end of discussion

    The long lived spent fuel tends not to have gamma rays. After a few hundred years you would nearly have to eat it to be harmful. I wouldn't as it is still a heavy metal. The high gamma emitters tent to be short lived. Cobalt 60 is a gamma emitter and has saved more lives then it has deaths. It is used for medical imaging and industry. half life of 5.27 years so after between 40 and 52 years it has decayed to pretty well nothing. 7-10 half-lives depends who you ask.
