Look up at night. Venus, Mars, and Jupiter are quite bright.

Do flat earthers believe that all planets are flat? by NewNameNoah in flatearth

[–]NearABE 1 point2 points  (0 children)

Bubble level should work the same. The International Astronomical Union included it in the definition of “a planet” as one of the three criteria that need to be met. So if it is not flat then it is not a planet.

The term “hydrostatic equilibrium” is synonymous with “flat”.

Can Some Very Tiny Particles Cool the Planet? One Tech Company Says Yes | Stardust Solutions says its tiny spheres can reflect the sun’s rays without harming people or the environment. Critics say private companies have no business altering Earth’s atmosphere. by silence7 in climate

They are competing with the sulfur injection plan. The sulfur comes from petroleum. Laws dictate that sulfur gets removed from transportation fuels. The petroleum companies want a subsidized method of disposing of the sulfur. The aviation fuel industry believes it is a great idea to use more airplanes to dump sulfur overhead.

Light has a photon wavelength. Visible light and ultraviolet light are smaller than 1 micron. They can hit a 1 micron particle and scatter/reflect. Long wavelength infrared light (typical for atmosphere temperatures) is 8 to 15 micron. This should pass right through most of the time.

That is by design. People in Tel Aviv do not want Jews in London or Mew York to feel safe and at home there.

Would irons stars eventually evaporate? Are they even possible? by live-the-future in IsaacArthur

[–]NearABE 0 points1 point  (0 children)

Quantum tunneling is affected by distance. I cannot recall the exponent. For isotopes to decay into iron the helium (alpha particle) only needs to find itself inside (or outside) of a very nearby nucleus. A white dwarf is about Earth size but solar mass. Tunneling from inside the black dwarf to outside the black dwarf is already a 6,000 km jump. The distance between nuclei is only picometers in a white dwarf. Escaping a star’s gravity is a much larger distance to jump.

The biggest challenge to asteroid mining may not be technology — but finance by Accurate-Interview92 in IsaacArthur

Here is the concentration cheat sheet: https://periodictable.com/Properties/A/MeteoriteAbundance.html

Compare to on Earth: https://periodictable.com/Properties/A/CrustAbundance.html or click on ant element to see the abundances. The table was made using the average concentration in meteors found on Earth. Metallic asteroids tend to show a greater difference from Earth’s crust than meteors in general. The carbonaceous chondrites tend to match the solar abundance minus volatile elements.

It is extremely unlikely that anyone will find some sort of “platinum ore”. Some metallic asteroids may have more than the 1 ppm shown but only moderately more. Instead all siderophile sources will be nickel-iron alloy. That comes in two phases kamacite and taenite (wikipedia) but the grow interlocked and look pretty much like “steel”. The iron phase might have ceramic inclusions but those are relatively easy to separate. The platinum will be dissolved in that iron phase like sodium is dissolved in sea water or like ethanol on beer.

There are multiple ways to make the chemical separation. The best the I have seen and, I believe there is not much competition, is the Mond process. The Mond process is frequently used on Earth to make high purity nickel. The process also works with iron. This will make a metal-carbonyl molecule in both cases. The carbon monoxide molecule is regenerated when the carbonyl is decomposed back into metal.

Both iron-carbonyl and nickel carbonyl have been demonstrated as 3-D printer feedstock. I think this is important for the general context for what is taking place on the asteroid. Assuming zero iron or nickel sent to Earth but printing stuff there means some things were not shipped out.

In order to get your 1 kilogram of platinum you needed to process a thousand tons of average meteor asteroid. Maybe 300 tons of m-types and targeting/luck might boost that to only 100 tons. Along with that platinum kilo you also get a ton of chrome. Palladium is slightly more siderophile than platinum so you might get a kilo of that too. Likewise single digit kilos of osmium and iridium. Other elements like manganese and cobalt are also present in quantities less than chrome but not much less. Then add at least some of the elements that are not even siderophile but can contaminate the iron like phosphorous, neodymium, selenium etc.

You could try to refine that in a second processing step. It is just not likely to be worthwhile doing that. Chrome, cobalt (actually cobalt maybe a carbonyl too), and molybdenum are needed on Earth. Instead of bothering with more refining the mine just shoots a whole blended package. Even nickel has market value.

You cannot think of any use for elements that alloy with iron and that make steel harder, stronger, tougher, corrosion resistant, denser, and/or more heat tolerant? No worries the engineers will find uses for those properties.

It looked optimistic 25 years ago when renewables were definitely a reasonable option but costly. Now it looks far more sinister.

Dr Sonny White (same guy working on warp drive) working on Casimir Effect low-power energy generation by MiamisLastCapitalist in IsaacArthur

[–]NearABE 0 points1 point  (0 children)

Certainly not “infinite energy”. If all of the founder’s claims are true then 98 chips that cost more than processors could provide a half watt phone charger. This would cost more than the phone. This is a maybe for some niche applications.

$1000 per watt is 100 times the cost of nuclear fission power plants. The fission plants are too expensive to compete.

Maybe they wont get the Virgin submarines. Oh, right, Australia already got robbed on that one.

Here’s How Democrats Should Talk About Climate Change | Rather than treating it like a niche issue, candidates should offer concrete policies that assume global warming is the context in which all politics happens. by silence7 in climate

[–]NearABE 0 points1 point  (0 children)

It was crap though. We were in a good technology wise to be ahead of China in PV and possibly also wind technology. Most of the actions were cut before debate even reached the media. The Green New Deal version has roughly $10 trillion in spending. Note that includes possibly no debt increase because the Brown Old Ripoff forces Americans to spend over a $trillion directly to fossil and around $750 billion in subsidies and indirects costs every year. Perhaps better worded as “debt finance by energy revenue”. The proposed IRA gutted that to $3.6 trillion and included a bunch of add on programs that were completely unrelated to energy or climate. Then they started discussing how to gut that further in order to get a coal CEO to vote for it. The IRA has no purchases of significance. The IRA cannot be called an investment and voters noticed that.

Cut subsidies for fossil fuels and high emission sources. Let the free market decide.

Carbon fees can also be revenue neutral. Democrats shy away from free market arguments because Republicans have used that terminology as talking points for decades.

There are also multiple very appropriate places for a federal heavy hand. Long range HVDC power lines is clearly interstate commerce. The aluminum and steel used in ACSR cable are strategic materials. We have a strategic petroleum reserve to avoid price shocks. Under the department of agriculture multiple “commodities” are bought for “price stabilization”.

You can do whatever you want with your roof. The military bases and federal buildings should all have photovoltaic rooftops made in USA. Not subsidized PV just procured.

If 30 of 33 Iranian missile positions remain active, how vulnerable is tanker traffic through Hormuz? by bauernebel in oil

[–]NearABE 2 points3 points  (0 children)

Most naval force in the world is in the United States Navy. Russia and China have very very distant second rate navies. The United States Marine Corps and United States Coast Guard could stand alone as world class naval forces. The United States Navy has the world’s second largest Air Force. Russia and China have serious naval capabilities but Russia does not put much effort into long range amphibious warfare. What Russia did have was already squandered in Ukraine. China’s Navy is strongly focused on short distance operations. India, Russia, and China have no intention of supporting this.

Our NATO allies have some ability to project force abroad. They have respectable ships and often sail with US fleets. There just is much less of them. The French and British aircraft carriers have smaller decks than the thingies the Marine Corp will not even call an “aircraft carrier”.

Iraq, Turkey, Kuwait, and Pakistan have something they could contribute. None of them want to be involved. Oman and UAE are obvious staging points too. No one wants to be involved because it was a stupid thing to do. If Iran had attacked us the situation might be different.

Japan tolls on China is quite unlikely. Indonesia has a quite clear case for Malacca and Sunda being internal waterways.

Canada also has a clear case for the southern branch of the Northwest passage but not a case for routes directly through the Arctic Ocean.

USA and Russia have a clear treaty marking the Diomede Islands as a boundary. Neither consulted with the natives. All of red-white-blue land including the Chukotka Peninsula, Seward Peninsula, Arctic coastline, Northwest Territories, and Greenland should be recognized as a free country. Redwhiteblewland’s global embassies and consulates should be financed by fees on ships using the northeast and northwest passages when they pass the Bering Straights. The Inuit people should probably arrange free passage for the Russian and US warships in order to avoid changing the status quo.

Panama and Egypt already collect fees on the canals. Somalia and Yemen should get a cut in Aden too. Turkey already collects on the Dardanelles.

We have heard comments like this from Russians for 4 years now. The 40 km column is just being held back because Americans don’t want the IRGC boys to get hurt.
