  1. Below is a link to the Japanese Govts roadmap summary, as regards their aim to build a hydrogen economy. Be assured the Japanese effort to build a hydrogen economy is not a fractured effort - it is fully co-ordinated at the highest Govt level, and funded with multiple billions of yen, to ensure that their roadmap targets are largely met. The Japanese are targeting 2025 as the date for a major increase in hydrogen use, and 2030 as the date for establishing international hydrogen supply chains. However, the Japanese appear to be concentrating on hydrogen fuel cell technology as the pri
  2. ....declined to see a dentist, and continued on his merry way with his gap-tooth appearance giving him real street cred, anytime he got surrounded by hard-core beer drinkers, and he'd ordered a gin and tonic whilst right in amongst them. Of course, it wasn't just the missing teeth that gave Cappy real street cred - it was the tattoos, as well. Especially the dragon one, which snaked across his chest and down to his.........
  3. I often wondered if exhaust heat could be used for de-icing - but lo and behold, the Americans thought of, and considered that, as well - in 1940. https://ntrs.nasa.gov/citations/20090014183
  4. Both the U.S. and Japan have very active and large Energy Efficiency Depts working flat out on getting hydrogen storage systems to be effective, acceptable cost, and compatible with fossil fuels. Both countries have targets within the next few years that they seriously intend to meet. The real bugbear with hydrogen is trying to densify the gas to meet the same energy density levels as fossil fuels, without incurring major weight gain or high costs. Cryogenic hydrogen is the way to densify hydrogen, but I cannot see any satisfactory solution, as regards making a small and low c
  5. Ian, here's the link to the scientific report that came to the conclusion that air pollution in Northern Italy (specifically the Po Valley, which is highly industrialised) led to a far greater mortality rate for COVID-19 patients, than many other regions in Italy. https://www.sciencedirect.com/science/article/pii/S0013935120313566
  6. I have a serious level of concern whereby an international panel, formed by a defacto Govt (the U.N.) that is essentially responsible to no-one (because it's a global organisation), bases its entire existence on one factor, and one factor alone - global warming. This panel must continue to justify its existence to its masters (the U.N. bureaucracy) by constantly keeping to an agreed story - that the world is heating up to the point whereby in the very near future, mankind will cease to exist, such will be the drastic climatic changes. There are several problems here. The IPCC
  7. A genius in his own mind, perhaps. The thing that gets me is his absolute preciseness of the aircrafts location, based on some exceptionally weak signals. Weak signals can be from a multitude of sources. If he's confidently predicting he can find the aircraft at that pretty precise location - and it's in an area previously searched by the Fugro crews - then surely there must be logs of the seabed and other records from the Fugro search information, which can be gone back over, to see if they really did miss that pile of wreckage.
  8. The news outlets this morning are full of the latest story about a British expert who has used new cutting-edge technology to find the precisely exact location of MH370. I guess the searchers would really have liked him to be around, when they were searching during the massive, high-tech, $200M ATSB search. https://www.perthnow.com.au/news/british-expert-pinpoints-precise-resting-spot-of-missing-flight-mh370-c-4767473 This is the link to the experts highly detailed report. It is quite possible the aircraft slipped into a ravine, and was missed by the search ships.
  9. At about 6:00PM last night, I watched the contrails of two very high-flying large jets (one about 5 mins behind the other) overflying my workshop in Perth - one heading directly South, and the other one, directly S/SW. There's only Antarctica and the Southern Ocean in those directions, and you just almost never see flights heading that direction and at that height over Perth. However, I have seen them a couple of times before, in the last year or so. I'm guessing they're long-distance U.S. military flights for some reason. I haven't looked up FR to see if they appeared on there.
  10. There's nothing "lucky" about what the police are doing. They have a vast array of information sources available to them (multiple cameras, satellite photos, phone tracking, vehicle tracking, eavesdropping utilising high-tech equipment, surveillance - and good old "public information") - and they're throwing a lot of police resources into the discovery of evidence. They're doing very good work, and when it's all finished, I would not be surprised to see commendations come out of their policing work. By far the best piece of policing was examining the burnt tent, and concluding that the fi
  11. This sad reminder of how even an experienced pilot can make a poor decision, and essentially ignore the basics of engine failure, is probably a good time to re-read the coroners report, and to revisit and practise your immediate and automatic response to any engine power reduction. The crucial factor in Ross' crash appears to be the fact that a partial engine failure, is often not treated as a full EFATO, and the experienced pilot still thinks that he has enough power to carry out a turnback. I can recall at least one other fairly recent crash where an identical series of events happ
  12. There are two things that will govern the direction that energy sources for transportation comes from, in the next decade or two - and that is R&D, and any outstanding technological breakthroughs, such as in battery storage/efficiency. With the amount of money and effort going into R&D for potential future fuels and battery development, I would not be in the least bit surprised to see a major breakthrough in some area in the very near future - and I suspect that breakthrough will be in battery storage ability and efficiency. Virtually every major university in the developed world
  13. Ian - There is a company in the U.K. reworking the EE20 Subaru diesel for aircraft engine use. Their version does produce 240HP for takeoff (140 maximum sustained HP), but it also appears to weigh over 170kgs, all-up. http://www.cktaeroengines.com/ Subaru had problems with the earlier EE20 engines breaking crankshafts - but they carried out engineering modifications to the crankshaft around 2010-2011 that appear to have eliminated the crankshaft breakage problem.

  14. I bought a Subaru diesel engine at a farm clearing sale, where the seller told me he'd planned to install it in an aircraft. I questioned him about whether the engine was an excessive weight for an aircraft, and all he said was, "No, not if you have the right aircraft!". But he never told me what that particular "right" aircraft was, I was too busy picking up and loading the items I'd bought. The engine has reputedly only done 11,000kms, but I can't see myself selling it to anyone with an aircraft. The engine is only a basic engine, it came with no ECU, no intercooler and no muffler - bu
  15. The need for a six-fold mining increase is not an accurate projection, because it fails to take into account, the recycling of used batteries. Battery recycling will become a very sizeable operation in the future, in every country in the world. Lead acid batteries are now recycled at a rate better than 60%, with huge savings in reduced landfill costs and reduced pollution. All batteries are recyclable, the common household batteries are being recycled at an increasing rate and very shortly lithium battery recycling will be rapidly increasing. We have to do better than just constant
  16. The changes will come a lot faster than 50 years or more. Already, numerous Govts have decreed that fossil fuels will not be supported in transport systems within less than a decade. The next stage is, fossil fuel users will be having to wear "pollution taxes", making owning, older fossil-fuel-powered items, a real cost burden. This will happen, "to reflect the true overall cost of fossil fuel burning". Just the same as the Japanese vehicle inspection/registration costs ("shaken" in Japanese) go up enormously after 6 years, forcing owners to upgrade to new, lower-emission vehicles,
  17. .....dealing with the female warriors of the Greens Party Female Collective! I mean to say, there nothing more vicious and violent than a hairy-legged Greens peace protester!" Meantimes, OT had organised top actresses and actors, and a huge number of extras for the forthcoming movie. He also organised a large number of RA-Aus ultralight owners to feature in the film, as it was to be seriously aviation-related, and more importantly, recreational-aviation-related. As with all good movies, it would feature horror sections (combat with Greens warriors), bravado (starring Cappy), d
  18. The Japanese manufacturers are pushing hydrogen fuel as a viable source of power. They are also pushing battery power, so they're obviously having a 50c each way bet. There are quite a number of global manufacturers who see hydrogen gas being fed into a slightly modified IC engine as the immediate answer. The construction industry is looking at this seriously. Lord Anthony Bamford (he of the JCB digger fame) is not convinced that batteries are the answer for construction equipment and is going down the road of simply modifying his IC (diesel) engines to run on straight hydroge
  19. .....left nostril - which regularly made for angry goannas. And when you've got a number of angry goannas, it's time to look out! However, the Stumpy Tail Lizard Farm, being another subsidiary of Turbine Industries Inc, rarely let the odd angry goanna bother them. "Odd Angry Goanna?", said OT, "That's sounds like a winner of a name for a new movie featuring the Outback, two or three crusty old pilots, some wildlife, wild animals of the interior, possibly a few camels thrown in for good measure, and several ultralights that the pilots are fighting for ownership over!" "I
  20. Our family raised a wedgetail eagle from a chick, back in the late '70's. We had a 5 acre block on the outskirts of a country town in the W.A. wheatbelt, back then. We used to do a lot of farmland clearing in that era, and finding nests in downed trees was common. We took home this big wedgetail chick we found in a nest in a felled tree, and raised him to adulthood. Couldn't do it today, too many wildlife laws, we'd be hung drawn and quartered for not having a wildlife permit, taking a protected species, and a dozen other laws, I probably don't even know about. He was abo
  21. ....show everyone at the meeting, the numerous "hacks" you could do with used chopsticks. He showed them as suitable for use as paint stirrers, how they were good for toothpicks (they get big gaps in their teeth in Tasmania), how you could use them as knitting needles (whereby bull promptly knitted up a pair of thick socks for protection against the cold at 4000 feet), how they can be used to unclog glue and sealant tubes, how they could utilised as picture frames, how they can be used as a kitchen whisk, and how they could be used to rescue toast that was stuck in the toaster. In
  22. ....took a fighting stance and flexed his biceps - and the Tyro tyre automatically assumed an inflated position. "So, who says I can't fly sh*t??, demanded Cappy menacingly. "Do you know who I am?", said aggressive XXXX. "No, who exactly are you?, said Cappy in response. And just like Norm in the Newcastle Song, the aggressive XXXX replied. "You find out, mate!", and he promptly swung.......
  23. ....being a closet gay, and this was reflected in his choice of drinks. Many a time, Cappy was asked to leave bars in the wharf area when he ordered a gin and tonic, whilst everyone else in the bar was drinking XXXX or VB. "I can't understand this rampant bullying over my drink choices?", he complained. "It's not like I've.........
  24. Wouldn't a set of wheels left down and left to spin at takeoff speed, after takeoff, take a considerable length of time to slow to low RPM's? - and wouldn't that set of spinning wheels, which are usually unbalanced due to flat spots from landing, provide a level of gyroscopic imbalance to the aircraft?
  25. There would have to be a very sizeable proportion of the population engaged in growing kelp to provide the quantity required for our current levels of fuel usage. Australia consumes 90,000,000 litres of petrol alone, every day. Daily Gasoline consumption of the U.S. is 1,285,000,000 litres. Jet fuel consumption for the U.S. is 170,000,000 litres daily. And these are 2020 figures, when fossil fuel consumption figures were subdued. I think solar-produced hydrogen, and solar-produced electricity, have vastly more potential than trying to grow our fuel requirements.
