Do not forget the most Important one to a hot day. Sublimation phase change. This is easiest to demonstrate on a very cold beer, often left in freezer a few minutes to long. Your beer comes out perfectly chilled but on the point of almost changing phase to solid. Now if you tap the bottle the extra energy introduced is sufficient to instantly sublimate and change phase. A tiny amount of energy, just from the friction of molecules on movement, the gas pressure changes in concert enough to cascade to a solid. Also happens when the pressure drops by opening the bottle or can. This all happens in a few seconds and will form ice which then turns to aerated ice to foamy ice and then just foam and beer as it loses to ambient temp its high speed magic. Its a science lesson in a perfect cold package. I have a passion for cold cold beer and always love this trick , as long as I have a currently liquid one on hand. The science of vitamin beer.....priceless. Lucky I am dedicated to scientific method. Off to the laboratory to do more beer........

I never reuse beer I have consumed. Oh........you meant oil? Nah , if the Alfa decides she does not like that oil mist, who am I to argue. Never give her anything but fresh pure coarse plus. Her belly at 6.6 litres allows for lustful healthy thirst. I don't pee in a cup and then redrink it either.

Brilliant engineering always has its place. But a German beer gives better quality. The Italian beers provide flair. A English beer should never be drunk when doing electrics. Damn you Lord Lucas....

Bex, Good to see you have not aged.

Love it. Years ago....I had a very forty Alfa Romeo. Could be heard for miles at night. Alas a non deaf police patrol waited in anticipation and sprung on the Alfa. The actually wanted to have a purve mainly. They did however laugh at the catch can, since I ran four pods on alloy ram tubes. A bespoke stainless bracket, tube and a Orchy juice bottle. It worked fine.......... Fine was coming if I did not change it. Some just don't appreciate quality engineering.

Sure the VW crew got caught. But the EU cracked down. People got jailed, billions on fines, consumers were compensated in Europe. Management took a bit hit. Not perfect but a far cry from the USA. In Europe if found out you generally get punished and systems change. I the USA unless politicians want your head, you get a raise.

Sage advice. I will never unless a absolute emergency get on a 737 Max. Just not trustworthy to me. Even with a top airline, they can't trust the aircraft. Why would I? Jet flights are a rarity for me, I am selective. I vote on ethics,safety and integrity. None apparent at Boeing.

They are only doing some flights to move fire fighters. They are not doing anything a commercial lift can't do. So more a branding exercise for gov than a big effort. But if you watched Parliament last week, you would not know they cared.

Government need to get off the fence and realise the new regime of fire. We need the military to be available and respond like it is war. Other countries have no issue doing this. We can't just let fires start and not do everything possible as early as possible to stop the fire before it get way out of control. The Tassie fires were let go when early work could have made a big difference. Not just the military either. The gov needs to invest billions a year in machines and personnel. This is a national emergency that will only get worse. We are watching billions of land, farms, homes and millions of animals die. We need to treat fire like a enemy in war, it his no mercy and will not stop without rain and or massive human effort. If the use of military assets means they wear, good. At least they are been used, as are the personnel. RFS should be much better resourced and paid for their time, trained free and fully supported. We don't do pay free police or military volunteers, so why should fire fighters be used and abused because they want to help. All society needs the RFS so should pay.

I have the same problem as Bex, Everywhere I went yesterday, at my side was a vision of me. At the yacht I inspected, when I had a beer and fish at the docks. Even in the bloody car. Bloody twin brother

I only trust west systems. Simple, easy and well known. I have tried other brands and not gotten the consistent quality needed. About to do mods to glass boat and will use west, ply and micro etc. Also making a diy safety collar for hull. Too many old nuggets drowning lately. That is epe foam probably., Boat coat has a good name just never used it. I feel the low % part 2 expoxies are inferior. Ratio gets a bit critical, west is more accommodating to diy.

I am sure you meant 0.5 mm not 0.05mm. Will such thin 0.5 mm be string enough? Is their a inbetween you can get like .75mm?

We take our whole lives wrecking the planet. The least we can do is not make a toxic tomb for ourselves. Either feed me to the fish and make me protein or plant me under a tree and I can feed the future. No box. no fuss but have a drink and party well.

A issue with RAA doing the fee collection is a vested interest in more fees to collect and higher fees for airports rather than resisting the charges as they should on our behalf. I can see dollars in their eyes now.

If it involves google or Facebook, The precautionary thing would be to assume its not a innocent mistake. They even admitted to data manipulation and political influence are all fine for profit. If you believe they are innocent .... I have a bridge to sell you.

His money was well spent if the aim was to put the lnp back in power. It worked a charm.

Just in case someone wondered... I do not take overseas airtrips, never have. I have a frugal scooter for most travel or use public transport . I borrow a car if needed. I buy very little packaged food. I travel only if really needed. Have not been in a jet for 11 years at all. I do not buy much and use wisely My prop flying is rare and not as a just burn fuel exercise. So I accept and adapt to the reality. Each makes their own choices. My family are farming stock since the 1830's . Merinos, crops and even cotton. I think I have a reasonable take on things, I am not a latte sipping urbanite in nature nor training. I started the multidisciplinary team at UWS Richmond in agriculture/horticulture and social ecological systems in 1997 to develop industrial Hemp in Australia. We got a research licence to grow and trial. There was no pay in it. All money went to research costs. The government barriers were massive. Industry hated us. Farmers of cotton were very keen to get involved. The levels of cancer and other effects from the pesticides drove them to us. No amount of effort could overcome the political nunskulls for another 25 years. Then they saw a buck in it personally and changed. I also work in disabilities, always have. I am not talking out my arse. I have no vested interest other than concern for our blue orb and life on it. I don't earn a cent from any side. I do not begrudge a person their lifestyle or job but collectively we must change course. The sooner we do the easier it is.

Yes, Decentralised power systems are far more efficient and much easier to do with the users owning the grid. Ie homes, businesses , farms etc. From standalone to local networked new suburbs, townships - community non profit model is ideal. Maximise the benefits and lowest cost. No profit motive just fair payment for renewable power. The economic multiplier for a community is huge. All that power and its jobs is local, as is the billing money. Plus bills are a lot smaller overall. So more money can be available to spend on stuff we need for a good life. But big business, power companies and money men hate that idea. To them democratization of the power to the people kills their old business model.

Jetr, Would you prefer all water for upstream farmers to use at will and bugger anyone below? We know water is a flood and drought issue but hiving it off just destroys the system that would get those high flows in rain times. Look at Mexico, the USA has created a desert by taping all the flows of the Arizona river before it flows past the border. It has had massive effects and all so those up stream can grow anything they want, so Las vegas and Nevada can be spots of green in a desert. California gets to grow almonds. Wars will be fought over water access in the future. China is damning every source it can and stopping flows into border countries. Even our military accept this will cause war.

Growing fodder with desal at least feeds something but is a short term high expense stop gap of a very political nature. It is a very dumb way to get feed for stock and definately a case of government picking winners- those who get to grow with the water will get windfall profits I expect. This is costing hundreds of millions of public money.

So you are suggesting that all the water resources should be for farming only or what mining? You do know that nature needs water to exist? What right do some at the top of a system have over everyone further down? And the communities that use those lakes of potable water, what about the wetlands? Constantly flowing rivers are not the enemy of farmers, when they don't flow the environment and local economy collapse. How do you think SA would get water to drink, or should they desal so a farmer can plant cotton? Your attitude about water says a lot about your view. I have never promoted pumped hydro as a big solution but merely as a way to capture energy that would be a total loss.

Mate, I never said make it illegal, I said industry policy should aim to suit the best possible use of the limited water and resources we have. Governments, business bodies, farmers federation all pick winners and losers when they lobby. Governments all do it everytime a decision on anything is made. When policies are made, laws, regulations, political decisions and trade deals. All involve a opportunity cost. If x amount of water can only be used then it is governments responsibility to guide how that water is priced and used. IF the best bang per litre for the overall community, environment and economy is sought- then cotton is a poor use. Picking winners when doing our water policy and esp the Murray Darling system is a big cause of the problem we are seeing- they had a very big opportunity to guide the market and become more sustainable but choose a capitalist money grab version instead. Stupidity in making decisions does not mean make none but choose wisely. Agreed and as a policy we should not encourage nuts trees like almonds, the long term water use is extreme and drought can wipe them out for years. Look at California, huge amounts of water they can not afford is going to almonds and the rest of agriculture , the populace and environment suffer greatly. That is the long term experience. Tell that to other farmers who do not have access to water downstream and whole communities. If you are saying a export fibre crop is better than food crops consumed here, you need to think about carefully. The economic and flow of benefit is much better for the food side. More labour and output stays local and generates jobs. As a export crop cotton is reliant on mass imports of energy, machinery, chemicals, seed development (BT Cotton)- this inputs are mostly just imports and even when made here are from imported parts and capital. The more you import to run a export industry- you impoverish local opportunities over foreign ones. The benefits are felt by few and the real cost to others who farm or use the rivers is great.

As the report stated without substantial support and policy assistance they will not exist. A lot of the so called claimed starts are now been put on slow mode. Any new plant will still have massive support and not required to internalise all costs. That is the model they use. Allowing any nuclear is a pronuclear stance and picks it as the winner for 40-50 years, the level of support is fundamental. It can never be removed as economics change. Prices and support are baked in. That is picking a winner and providing huge amounts of real and potential treasure from the public.

And thats the bitch of it. A prick to remove but if you want unmarked sheets it is generally all that is available. Then you get to scratch it removing it. But storage is the bugger unwrapped as well. Have not had paper supplied ones. I bet a paper coated one would be best and easiest to remove. To have to resort to soaking, vingear etc is ridiculous in 2019. Its not like the bloody stuff is cheap or anything. Rant over.

See if we ever needed proof, the evil Thatcher had a small conscience and respect for facts, it is there. Come on fellas if she can do it, anyone can. Or at least see the oncoming bus blinking its lights, slamming its horns and get out of the bloody way. Even John Howard could do that.
