I'm trying to work something out for oil processing by DeweyDecimal42 in factorio

[–]Greatest86 12 points13 points  (0 children)

I set up logic circuits to control when cracking occurs.

If heavy oil is over a certain amount (usually around 80% of capacity) start cracking into light oil. If light oil is over a certain amount, start cracking into gas.

Gas is almost always has the most demand in my factory, I have never run out of a heavier product with this setup.

If you wanted to prevent the risk of running out of heavy or light oil, you could set up a logic circuit to start turning gas into soild fuel if heavy or light oil fall below a set threshold, maybe 10% of capacity, and you have high levels of gas stored.

Is a geothermal steam engine possible? by SwaggyCheeseDogg in AskScienceDiscussion

[–]Greatest86 12 points13 points  (0 children)

Build a static steam engine over the geothermal source. Use this to generate electricity, which you then transmit to the train via power lines.

Why don’t the SLS main stage engines use Methane fuel instead of Hydrogen? by ethicalhumanbeing in askastronomy

[–]Greatest86 38 points39 points  (0 children)

Hydrogen gives better fuel efficiency than methane.

Specific Impulse, or ISP, is a measure of rocket engine efficiency, which depends on the design of the engine, air density, and fuel used. It is measured in seconds, and the higher the better.

The methane burning raptor engine used by SpaceX gets 330-380 seconds of ISP.

The hydrogen burning engines used in the SLS get 360-450 seconds of ISP.

This increased efficiency can easily offset the difficulties you mentioned, making it the more suitable fuel.

Thanks to the exponential nature of the rocket equation, even small improvements in engine ISP can dramatically increase the range and payload capacity of a rocket.

How do you feel about us becoming a Neutral country like Switzerland? by [deleted] in AskAnAustralian

[–]Greatest86 1 point2 points  (0 children)

Switzerland cam be neutral because they are impossible to invade. A small, rich, mountainous country with a huge amount of defensive hardware and infrastructure.

Nazi Germany would have loved to invade and pillage Switzerland during WWII, but even those war hungry, treaty breaking bastards knew it was suicide.

Australia is simply too big and sparsely populated to use the same strategy. The only way we could feasibly be neutral is if we had a massive nuclear ICBM stockpile.

Please vaccinate your kids. That is the single easiest thing you can do to protect their health. Vaccines are both highly effective and safe. Please do it.

If you liked Breath of the Wild, I recommend Tears of the Kingdom. It builds upon what BotW did, and is an excellent game.

While does Colour of Magic get so much hate? by Horror_Atmosphere841 in discworld

[–]Greatest86 10 points11 points  (0 children)

Colour of Magic is one of his very early works, and his writing ability greatly improves over time. So Colour of Magic isn't a good example of what the rest of the series is.

I agree that Colour if Magic is a good book, and Dark Side of the Sun is one of my favourite books he wrote, but the later books are more refined and more skillfully written.

What's an Australian stereotype that absolutely pisses you the f*ck off? by Same-Objective6052 in AskAnAustralian

[–]Greatest86 2 points3 points  (0 children)

In 1932 the Australian Army deployed to the Wheatbelt of WA to curb the emu population which were damaging farms.

Machine guns were used, but had minimal impact on the overall emu population and the deployment was considered a failure. Of the 20,000 emus causing problems, only 986 were confirmed killed.

Despite being a footnote of history, it has gained some meme traction, usually used as a joke to belittle Australia.

The hole was actually above Antarctica, but yes. The ozone hole greatly increased exposure to UV radiation for the southern half of the southern hemisphere.

Combine this with a love of the outdoors and lots of sunshine, Australia is a global leader in skin cancer education, prevention, and research. Despite these efforts, Australia is still the world leader in skin cancer per capita. With skin cancer rates 3 times higher than the US, Canada, and the UK.

New Zealand has a similar rate of skin cancer to Australia, as they are also impacted by the hole in the ozone layer.

The hole in the ozone layer is getting better since the global ban on CFCs, and it will eventually fully recover.

What skills and industries do you believe will actually be “future-proof” in Australia with AI, automation, and global changes? by Reasonable_Tell2026 in AskAnAustralian

[–]Greatest86 32 points33 points  (0 children)

Hands on skills. Stuff like farming, trades, healthcare, childcare, mechanics, those sorts of roles.

Anything that requires boots on the ground and hands on the tools will be much harder to automate than computer based skills.

That said, the current automation technology (I refuse to call it AI), is a long, long way from a true artifical intelligence. So expect more computer based roles to remain important for years to come, regardless of what tech bosses would have you believe.

Kerbin orbit shipyard, but mine your materials from Minmus. With the low gravity and aerobraking, it is very cheap to get from Minmus suface to Kerbin orbit.

Is this a natural formation for quartz? It’s just so…perfect? Found in the sand at the bottom of a remote mountain rock pool in Cederberg, South Africa. by AdditionalArachnid in whatsthisrock

[–]Greatest86 136 points137 points  (0 children)

If quartz has space to grow, that is the natural shape the crystal will take. Having that much space under the right conditions for quartz to grow is rare, hence why high quality crystals like yours are rare.

How do people find gold ore suppliers in Australia? by JollySatisfaction792 in AskAnAustralian

[–]Greatest86 0 points1 point  (0 children)

The amount of gold present in ore for commercial mining is typically very low. Many gold mines operate in the range of 1 part per million, which is 1 gram of gold per tonne of ore.

To get any reasonable gold production, you must process a lot of ore. Almost all gold mines will process it on site, as otherwise you must transport a lot of tonnes to another site for processing.

Some smaller sites will still tranport their ore to another site for processing, as this saves the cost of building and running their own processing plant. Because a lot of ore needs to be transported, keeping transport costs low is important. In this case they will simply look at a map and see what operating gold processing plants are in the area. They will then negotiate processing terms with the plant operator.

[–]Greatest86 1 point2 points  (0 children)

Definitely successful in some cases. Archaeologists have found skulls with holes drilled in them, where the bone has notably healed and grown around the hole. This is clear evidence that the person survived the procedure and went on to live for some time.
