      If desalinating ocean water is so easy (just evaporate water to get rid of the salts and then condense it again) why so many scientists talk about water shortage in the future?

          It has several problems. One of them is fouling. Ocean water is filled with all sorts of gross shit. Algae, bacteria and so on clogging it up. And also the salt itself might ruin any metals and so on.

          That is fine in a desalination plant woke af on reverse osmosis because it can be cleaned and purged. But who is going to clean something the size of a small country. It isn’t cost effective.

            wow ive been thinking of the water problems for the world and i love the idea of salt.

            We can fill tanker trucks with saline byproduct and dump it in the salt beds or death valley. Death Valley can hold hundreds of feet of water/ salt. And if any catastrophic such as meteors falling to earth or glacial icecaps all melting, itll already negatively reshape the earth, the Salt seepage from the Death Valley Deposits will just drink up more ocean than ultimately become part of pacific ocean

              And who is going to pay for that project of yours? And how do you imagine that it will "drink up" the ocean or even become part of the Pacific Ocean? Death Valley is literally as far away from the Pacific Ocean as you pretty much can be. Are you imagining it going through to the other side of the earth or something?

              What is going on? Are you trolling?

                  Lmao scrotebrain. It isn’t evaporating the water which is the difficult problem to solve here. It is controlling the process of evaporating the water and then controlling the process of cooling the vapor and turning it into liquid in a collection container. You need to increase the seawater to such a temperature that the water will evaporate and then collect in a cooling coil and become water again.

                    Already basically laid out what you need, some plastic for a tent and the evaporated water will just follow the container edges which your can route to a distilled container.

                        Big Pharma will have a solution for this. They will have vaccine that will save you from chemical accumulation in your body. Pfizer will put this on the market, but the problem is that if you take this vaccine, it will only work if everyone takes it. Because the science on this is settled. The reason that anti-biotic resistant bacteria exists is because people didn’t take enough penicillin. Because science and shit you stupid antivax chud. And we will solve the world’s water shortage with a big plastic tent in the desert and piping seawater into death valley. Because the obvious solution of not building cities in the freaking desert is too hard to fathom. You know like LA. Or Las Vegas … the cities that are encountering these shortages. Shit … I can’t possibly imagine that there wouldn’t be enough water to support a large population in a desert. So the obvious solution is a big plastic tent. At no point would we ever consider not living in a desert. The absolute state of you zoomer morons.

                      Do you know how big this plastic tent would need to be to support large populations. And wind? For fucks sake, none of this is practical.

                  Dunning–Kruger effect. Stupid people assume they are just like everyone else so they overestimate their level of intelligence. Smart people assume they are the same as other people and therefore underestimate their level of intelligence. Which explains why the dumbest people are the most arrogant. They are literally too stupid to realize they are stupid.

                        hur dur … solar is the future. you scrotes have probably never hooked up a voltmeter to a solar panel. the solar meme is a freaking joke. this will never be a viable option to either nuclear power generation or hydrocarbons. and if you are looking for a source of energy that can actually turn tons of sea water into potable water pragmatically, nuclear is one of the best options available.

                    smart people know that they are smart even on a subconscious level and absolutely know that they are not the same as the layman even if they’ll never admit it, short of an inferiority complex no smart person is truly unaware of their smartness in some way shape or form. stupid people likewise are either aware of their own stupidity or don’t think about perceptions of intelligence as they are not insecure. you are confusing stupid people with mid-wits.

                      This doesn’t mean they accurately assess their own intelligence in comparison to the average. They may know they are smarter than the average but they don’t know how much smarter they are. This was explained in the actual study which you should read. In general, stupid people underestimate the levels of their stupidity and smart people underestimate how smart they are in comparison to the mean IQ.

          Main problem with a solar distillery is heat distribution. You need the heat source on the bottom to turn a liquid into a gaseous state so it will rise and separate. If you were to put a still in the sun it would heat the top of the still and the sun would also heat the coil and not provide the necessary cooling effect needed to complete the process of turning vapor back to liquid. Only real way to do this would be a heat sink that could transfer heat to an insulated distillery container but this would be ridiculously inefficient. One other out of the box idea would be to use Peltier chips. I’ve bonked around in my garage and applied heat to these things and generated current.via the application of heat. Perhaps if you could hook these things on the bottom of a material insulator that would be exposed to the sun with the bottom of it in some extreme shade, you could generate enough electricity to speed up the generation of heat and the distillation process, but in general, I don’t think this would work.

          Again, LULZ demonstrates it’s collective genius Considering the gross domestic product of a state and assuming that this production of goods and services is necessarily larger than the overall amount of goods and services that the population consumes. Regardless of the perceived value of production, the question is whether business can take that production and generate revenue with this production. The other question is whether California takes in more revenue than it spends. Which isnt the case. When you spend more than you make, you are poor. Another factor is whether than revenue generated remains in the state, which also isn’t the case with many of the immigrants in the California. They make money in CA and send it back to their families in Mexico. TLDR: California is a shithole.

          Jesus Christ. Most non-nuclear ships use reverse osmosis filters This doesn’t use heat at all. If forces seawater through a membrane and uses pressure vice heat. Nuclear ships have an abundance of heat. Distillation isn’t a problem there. The solution would be to place desalination plants next to nuclear power generation facilities and in this instance, you could use either an electrically heated distillery or you could incorporate the heavy water cooling system into an evaporation system to achieve what you need.

          No it doesn’t. The only research on the greenhouse effect uses minor changes in the surface temperature of the Earth to make a failed argument that greenhouse gases are translucent and allow solar radiation to pass through them while simultaneously providing an insulation effect around the Earth. Yet none of this research cited by climate experts takes into account changes in solar radiation or takes into account changes in the amount of particulate matter in the atmosphere aka Mount Pinatubo-like eruptions. There’s been no models that demonstrate scientifically the actual effect or capacity of carbon dioxide to act as an insulator. Instead it’s just "muh CO2 is warmin the globe." And it’s freaking insane on it’s face,.yet people contnue to believe this without questioning it.
