Sorry...something weird happening with my reply ] Essentially the same process as coal liquefaction. Both rely on the production and catalytic conversion of methane in a hydrogen rich environment. We have all this coal sitting here that no-one apparently wants and it’s only cost of processing that stops us building large scale plants like the Germans did in WWII. Methane hydrate doesn’t offer anything over coal as a source of liquid fuels unless you are a net importer of coal, like China.

How?

Methyl alcohol is commonly known as Wood alcohol and is very poisonous And tastes awful. It’s added to ethanol at about 5% v/v to “methylate” the spirits to deter people drinking it In a process known as denaturing. i used ether and castor oil in my model aero engines but they were diesel type. It wasn’t only the aeroplane that got high. kaz

With respect to the Minister, there are more than 4 reasons as can be seen at https://www.dhhs.vic.gov.au/sites/default/files/documents/202003/Stay%20at%20Home%20Directions%20.pdf Unfortunately , there is no provision for maintaining property (hangars) and chattels subject to Deterioration (aircraft) Unless it is an emergency.

A lot of drenches contain chemicals in doses that will kill humans, too. Big difference between a ruminant gut and yours.

Sooner or later they will want to drill for it under Antarctica.

That’s how it comes. Doesn’t need to be “made” like avgas. Largely consists of methane with small quantities of the heavier hydrocarbons mixed in. Usually pumped in its gaseous form because of energy costs of liquefaction processes. Highly flammable with combustion in air producing primarily CO2 and H2O but may also produce SOXs and NOXs as pollutants depending on nitrogen and sulphuric content (similar to dirtier coals). Propane’s, butanes and even pentanes are more stable, less volatile (but can still go bang).

The most dangerous energy game of all. https://www.forbes.com/2008/08/29/energy-methane-hydrates-biz-energy-cx_wp_0902gashydrates.html Methane CH4 is the simplest hydrocarbon. It doesn’t form dipoles under pressure easily and to keep it a liquid at room temperature requires a tank that can maintain a pressure of about 32,000 kPa. That’s a tad more than your average aircraft fuel tank can manage. Low temperature are therefore necessary but you expend a lot of energy getting there The heavier “methane” hydrocarbons such as propane and butane are relatively easy to liquefy and store As evidenced by your bbq bottle. Their molecular structure isn’t symmetrical and the establishment of dipoles under pressure is that much easier. Obviously, the hydrate form itself cannot be used in aircraft because (1) the methane content is only around 30% of the mass of the ice and the amount of energy therefore available in that form is very small; (2) its not stable once released from the pressure/temperature of its source environment; and (3) there are significant safety issues associated with carrying liquefied methane in an aircraft...mix it with air in the right proportions and apply a match! The tanker depicted, if it is carrying methane, is essentially a huge liquefaction vessel with extracted methane under pressure and at at very low temperature.

And ABC report described the Jacobs Well aircraft as a “privately owned recreational aircraft”. At least it’s apparently not a Cessna.

Can’t tell you the name or I’d have to......no, no, it was a clip on Messenger and it now won’t open again. Sorry.

Hope you are ok? Lots of misinformation flying everywhere. just had an episode of a TV series sent to me in which the Chinese supposedly created a Coronavirus weapon with 90% mortality to take over the world. The sender was adamant this was Covid-19. The psychology of fear.

“You may not like the wealthy people, but they are the ones paying for most of the stuff that most people get from their government. If that goes away who's going to pay for your healthcare and pension then? I have no prejudice against wealthy people, but I question your statement that they are paying for most of the stuff people get from government. There is a huge difference between comparing the income tax rates of wage and salary earners where the highest paid 2% pay the largest Amount in income tax, and the taxes paid by owners of large mining corporations (for example) who have access to an enormous array of minimisation measures most of us can’t even comprehend.

Beautiful little aeroplane, highly aerobatic, NFG as a fighter against mono planes. The last biplane fighters in RAF service were the Gloster Gauntlets which fought amazing battles in Denmark. Highly manoeuvrable but 250 mph was their limit. Two .303 didn’t cut it, either.

That was the first band only time they escaped being slaughtered. The Me 109’s thought they were Spitfires and attacked from above. Defiant had quadruple machine guns pointing to rear. After Me109’s realised what they had, they attacked from below and killed may good men because of Air Ministry intransigence.

That’s an Auster

I hardly ever do a wheeler because you lose the very attribute that gave it purpose..STOL. Three points with the barn doors open and you can land it almost anywhere..and I have. But in 750 hours I haven’t ground-looped YET.

Wasn’t a cherry red one, was it? Mate had one at Coldstream YCEM and it was a delight to hand prop.

You didn’t give it enough time. They do grow on you, especially when you learn to fly them properly.

My young fellow and family are in Singapore. Foreign Correspondent has been looking at how Singapore managed it so well without a massive shutdown. Planned early, had adequate PPE and medical supplies on hand and people have high confidence in Government. Testing, testing, testing. https://www.dhhs.vic.gov.au/sites/default/files/documents/202003/Stay%20at%20Home%20Directions%20

Another magnificent day in paradise (SHEPP) and sitting on the ground looking at the sky. Autumn is a brilliant time for flying here and it’s flowing off the calendar at a very disconcerting rate. The Chinese trainees from Mangalore YMNG are still active with touch and go’s, and the twins are droning around the NDM, but nothing local at all.

I think the dual approach is fine, I just wish they had listened and acted sooner. Commentators like Bolt and Jones are positively dangerous IMHO.

I guess if you are travelling for one of the valid reasons, and only with family in the vehicle, you are ok, but it’s not terribly clear and reports suggest open to interpretation by police. If I fly from SHEPP airport to Wahring, for example and then walk around the boundary of this ALA for exercise, and do not approach another person, I’d suggest I’m complying with the letter of the restrictions, but not the spirit. Furthest I’ve been is to the lake around the corner for a quick walk with the dog. I feel terribly sorry for the flying schools which are deserted here.
