Is this a possible source of fresh water? In theory this is the way it works. There is a steady migration of unskilled labor thru the US southern border. Let's put them to work. That is the region where this idea can work. You need coastal deserts and lots of unskilled labor. There are coastal deserts on the Pacific side and the Gulf side of the US border, both in the USA and in Mexico. The idea is to build hundreds, then thousands, of shallow concrete ponds. The ponds are covered with glass made from abundant desert sand. Huge pipes deliver seawater from the Pacific and Gulf of Mexico into these coastal desert concrete ponds. Unskilled laborers mix and pour concrete slabs and manufacture glass. Inside the covered ponds the temperature gets very hot in the desert sun. That rapidly evaporates seawater. The condensation collects inside glass covers and flows by gravity to a central collector. After most of the seawater is converted into freshwater, the remaining brine in each pond is pumped out to a dumping area in the desert wastelands to create salt flats. Some of that salt and minerals can also be used later.

What are your trusted aggregators? How much do they charge? (I've never heard of an aggregator)

I still don't see how the moon could affect Earth's liquid core significantly. It could 3 billion years ago, because it was so close to Earth. The liquid core has been insulated from any moon/Earth-crust friction for a long time now. Or am I wrong?

How do you get your news? Do you watch cable TV and when there is an interesting story you follow up investigating it online? Or do you search news online? I usually watch Youtube, MSNBC or CNN, and take a quick look at Fox News or Newsmax occasionally.

Yes, but did you ever hear, in the news, that Trump wanted to exactly TIE Biden's number of votes in Georgia? I never heard about it in the news.

When Trump pressured Raffensperger to cheat and give him 11,780 more votes, it would only give Trump a TIE. Trump complained he was behind by 11,779 votes ("one more than we have"), so if Raffensperger would "FIND" 11,780 votes that would exactly match the number of Biden votes, and it would BE A TIE 😁 Trump: "So look, all I want to do is this. I just want to find 11,780 votes, which is one more than we have, because we won the state." Trump knows he won the state because he has big rallies and Biden doesn't. ‘I just want to find 11,780 votes’: Trump pressures Georgia officials as state’s runoffs approach (yahoo.com)

Trump let loose a huge Freudian slip when he said this to Judge Jeanine Pirro on Sunday, March 13, in regard to Putin waging war on Ukraine. This is from the Newsweek story and would love to find the actual interview on Youtube, anyone know? Trump's word salad with Russian dressing, about Putin waging war on Ukraine: "You say, what's the purpose of this? They had a country. You could see it was a country where there was a lot of love and we're doing it because, you know, somebody wants to make his country larger or he wants to put it back the way it was when actually it didn't work very well," Trump said. Trump Says 'Lot of Love' Behind Putin Wanting to 'Make His Country Larger' (newsweek.com) Trump explained the "purpose" of this war on Ukraine was Putin wanted to make his country larger. But Trump referred to Putin waging war on Ukraine as "we're doing it." "Doing IT" means waging war on Ukraine, and the pronoun is first person plural (Putin and Trump) plotting together. Whoops!! 😁

If anyone understands these 6 constants, please summarize them for us. I think Michio Kaku said the apparent fine-tuning suggests a multiverse of universes with all the wrong parameters, but OUR universe is the lucky one! Fine-tuned universe - Wikipedia "Martin Rees formulates the fine-tuning of the universe in terms of the following six dimensionless physical constants.[2][17] N, the ratio of the electromagnetic force to the gravitational force between a pair of protons, is approximately 1036. According to Rees, if it were significantly smaller, only a small and short-lived universe could exist.[17] Epsilon (ε), a measure of the nuclear efficiency of fusion from hydrogen to helium, is 0.007: when four nucleons fuse into helium, 0.007 (0.7%) of their mass is converted to energy. The value of ε is in part determined by the strength of the strong nuclear force.[18] If ε were 0.006, a proton could not bond to a neutron, and only hydrogen could exist, and complex chemistry would be impossible. According to Rees, if it were above 0.008, no hydrogen would exist, as all the hydrogen would have been fused shortly after the Big Bang. Other physicists disagree, calculating that substantial hydrogen remains as long as the strong force coupling constant increases by less than about 50%.[15][17] Omega (Ω), commonly known as the density parameter, is the relative importance of gravity and expansion energy in the universe. It is the ratio of the mass density of the universe to the "critical density" and is approximately 1. If gravity were too strong compared with dark energy and the initial metric expansion, the universe would have collapsed before life could have evolved. If gravity were too weak, no stars would have formed.[17][19] Lambda (Λ), commonly known as the cosmological constant, describes the ratio of the density of dark energy to the critical energy density of the universe, given certain reasonable assumptions such as that dark energy density is a constant. In terms of Planck units, and as a natural dimensionless value, Λ is on the order of 10−122.[20] This is so small that it has no significant effect on cosmic structures that are smaller than a billion light-years across. A slightly larger value of the cosmological constant would have caused space to expand rapidly enough that stars and other astronomical structures would not be able to form.[17][21] Q, the ratio of the gravitational energy required to pull a large galaxy apart to the energy equivalent of its mass, is around 10−5. If it is too small, no stars can form. If it is too large, no stars can survive because the universe is too violent, according to Rees.[17] D, the number of spatial dimensions in spacetime, is 3. Rees claims that life could not exist if there were 2 or 4 dimensions of spacetime nor if the number of time dimensions in spacetime were anything other than 1.[17] Rees argues this does not preclude the existence of ten-dimensional strings.[2] Fine-tuned universe - Wikipedia

That is interesting. It looks like the lower the mass, the easier it is to build and use. Too difficult on Earth, maybe even Mars, but the moon and asteroids are possible places to park a one-g space station with an elevator attached to the moon or asteroid. "Because of the Moon's lower gravity and lack of atmosphere, a lunar elevator would have less stringent requirements for the tensile strength of the material making up its cable than an Earth-tethered cable. An Earth-based elevator would require high strength-to-weight materials that are theoretically possible, but not yet fabricated in practice (e.g., carbon nanotubes). A lunar elevator, however, could be constructed using commercially available mass-produced high-strength para-aramid fibres (such as Kevlar and M5) or ultra-high-molecular-weight polyethylene fibre. "Compared to an Earth space elevator, there would be fewer geographic and political restrictions on the location of the surface connection. The connection point of a lunar elevator would not necessarily have to be directly under its center of gravity, and could even be near the poles, where evidence suggests there might be frozen water in deep craters that never see sunlight; if so, this might be collected and converted into rocket fuel." Lunar space elevator - Wikipedia

I don't see why you could not add living modules 2 at a time. It would be like constructing a merri-go-round while it is spinning. The tethers between two sets of balanced modules intersect at a hub point. At the hub the length of tethers may be adjusted to perfectly balance the 2. I like the idea of hollowing out an asteroid. You are creating a habitable void inside as you extract valuable minerals and water-ice. Then after you build a base inside the asteroid you have retro rockets get it spinning so those living inside would have one g as they stand with their heads pointing towards the center of the asteroid, AND they are protected by rock shielding.

"A space elevator is a proposed type of planet-to-space transportation system.[1] The main component would be a cable (also called a tether) anchored to the surface and extending into space. The design would permit vehicles to travel along the cable from a planetary surface, such as the Earth's, directly into orbit, without the use of large rockets. An Earth-based space elevator would consist of a cable with one end attached to the surface near the equator and the other end in space beyond geostationary orbit (35,786 km altitude)." https://en.wikipedia.org/wiki/Space_elevator If a space elevator could be constructed on Earth, it could also be done on the Moon, Mars, or any other moon in our solar system. If the space station was parked near an asteroid, with a tether between your one-g rotating space station, the gravity is so low that transport between work and home would be a short commute.

That sounds like a good idea. You start with "two balanced units, with a 224 meter tether." Then you can add more balanced units, two at a time. Over time many more pairs of balanced units can be added. It would be nice to park your rotating space station near an asteroid that has water ice, to create air, water, and fuel. The crew work an 8-hour shift in zero g, then take a space elevator to the space station, where they can sleep and recreate in one g for 16 hours. Even exploring Mars or the Moon, it would be better to have living quarters in a space station, orbiting the planet or moon.

This is the sweetest version I've heard, better than Led Zeppelin's version. Interesting instrument!

Is L2 a good place to have one or more telescopes dedicated to scanning for threatening NEOs and bolides? Or orbiting the moon?

Everything you need to know about L2.

Does that mean that if we could actually see a certain number of stars in a given patch of our galaxy, or a nearby galaxy, the JWST would be able to see 100 times as many stars? Also will it be able to detect 100 times as many distant galaxies on the edge of the observable universe? Yes, a little further back in time, not 100 times as far back. I thought "JWST is 100 times as powerful as Hubble" meant that a JWST photo will have 10 times as many pixels along the horizontal and 10 times as many along the vertical (10x10=100), compared to a Hubble photo of the same region of space. But as said above, 100 times as powerful means able to detect light that is 1/100 as bright as Hubble is able to detect. If the JWST was focused on Pluto, will it be able to resolve 100 times as much detail as the Hubble could?

What boggles my mind about JWST is that it is located four times the distance to the moon. That seems very, very far away. 😀 Once again I ask does anyone know what it means to say JWST is 100 times as powerful as Hubble"?

My experience is nothing was ever mentioned about the voting process, how ballots are transported, tallied, and kept secure from sketchy "employees." Also, they should explain what voter fraud is, how people try to commit voter fraud, what is the punishment if you get caught, etc. I've heard that real voter fraud is very rare is most commonly done by impersonating someone you knew that died.

Does anyone think that people should understand the voting process for their individual county? It seems to me that in high school, in the 12th grade, just before voters are 18 years old and can vote, they should take a civics course that explains, among other things, the voting process in their own county. Maybe this already exists in high school, anyone know? I still don't know exactly what happens to my mail-in ballot after I drop it in the box. What security methods are used to ensure nothing funny happens with the ballots? What will happen when the handling of the ballots is controlled by a certain party?
