Oh that's why raisins come from california.
Well, it's actually because Cali has a suitable climate for lots of niche crops. The overwhelming majority of our tomatoes, almonds, walnuts, grapes, strawberries, avocados, etc come from Cali.
Too soon xD
Oh shit, I just got the joke.
it is nice to be;) the joke is also nice^^
He has a dry sense of humour
or California could stop trying to grow rice in the damn desert.
"EVERYONE WE ARE IN A DROUGHT ERMIGERSH!", "no we are just in a desert", "NO ITS A DROUGHT GOVERNMENT HELP US!!!"
Yeah, didn't they build massive reservoirs in the early 1900's to get more people to move to LA? Also, isn't NorCal, a fairly cooler climate, doing pretty good compared to their desert neighbors?
+Joseph Stassup I live in norcal(Near Sacramento) and its pretty damn hot XD. It was at least 90 by noon. So no. Its not much cooler in norcal compared to socal
the dumb thing is rice doesn't even need much water to grow. People just grow it like that because it's easier.
tell that to the farmers. thats not a matter of public policy.

Ayyy Cody! I love your videos!
Cody you da best!!!!!!
Cody??. WTF
hey Cody, you should try to use a vacuum pump to desalinate water. and use solar to keep the water from freezing wile it boils.
What are you doing here?
Direct solar desalination was used in Chile some 120 years ago. Why can't such a simple method be massively introduced in California? Israel's southern city of Eilat uses it for most of its water.
the desalination in California is causing one of the worst and fastest extinction of local wildlife on the planet
Desalination takes ENORMOUS amount of energy, and California prefers to buy electricity at top dollar from companies in other states, rather than allow anyone to generate anything by any method inside it’s own borders.
I can't believe it! Desalination is what I've been studying for my Science Fair project this year! I'm hoping my prototype will win me something at ISEF. I'm not using any of the methods mentioned in the video though.
I'm using forward osmosis, and I can't believe they didn't mention it! In my opinion, it has so much more potential, it uses very little energy and is much simpler and cheaper to build and maintain. In my design I'm attempting to use zero input energy. My lips are sealed on any other details though, I might patent it! Thanks for touching on this topic!
Any luck?
Can we please get an update? Did you succeed in securing a patent for your invention?
Seawater is so salty... just like UA-cam's comment section.
lol
UA-cam is the brine recycling facility, except the only things that gets recycled are shitty jokes.
What the hell did you just say!?!?!?!
where does the salt come form to seawater??
From lol players
+Cycore Atleast its recycled and not thrown away to the landfill!
I lived in Los Angeles most of my life. They let all the coastal rain water drain into the ocean. stupid. just to stupid.
California has relied to heavily on their quota of water from hoover dam in Nevada. whereas Arizona has created many reservoirs to reduce their dependence on their quota of water from hoover dam.
Desalination requires energy. Power plants require water for cooling. Combine = win.
And I require what that is not contaminated with radiation
Power plants also need to service other customers, not just the desal plant, which is all it would be doing if you wanted to provide all the state's water needs.
We need more nuclear power plants anyway. The waste from those is technically a lot easier to deal with, since it doesn't, you know, go into the atmosphere. Just bury it really deep and you're good to go.
My thesis in university was centered on this idea..The people telling you you're stupid are wrong. It requires some clever design and engineering, but it's absolutely possible to have a nuclear power plant that desalinates water without irradiating it. In fact, the steam that comes out of cooling towers in our oldest, least efficient, most dangerous nuclear facilities isn't radioactive, which is precisely why they're allowed to release trillions of gallons of it into the air (I don't see how that isn't an obvious conclusion).
+spindash64 Maybe Thorium reactors.
$25,000 per month divided by 1,200 homes works out to $20 per home per month. Not too heavy a lift.
Sounds like shovel ready jobs.
We wouldn't just pay them minimum wage. You'd have o pay them more than that to get competent plant operators, and there's likely all sorts of things that you aren't considering.
da hell? 300 liters per capita per day?? how about use less? lol crazy folks...
Yeah Chris Urquhart there are a bunch of up front capital expenditures and then continuing expenses s $300 per household isn't so bad. Hell I shell out just that between natural gas and electricity every month. And when I think of it, as far as drinking water we spend about $40 per month right now.
$20 a month for water is ridiculous... Plus there's building the thing in the first place but no one will do that because by the time it's done the drought could very well end and then the company goes bust. The only real way is for the government to do it but they won't because the US government pisses away money on useless shit
There is the Beijiang Power Plant located in Tianjin. The power plant boiler itself uses desalinated sea water and is fired using coal. The hot steam from the exit of the turbine is used to heat the sea water in a multi-stage flash process and other industrial processes nearby, as well as providing room heating for the nearby communities. The desalinated water goes into the city water supply. The brine also goes to the same industrial processes nearby, which provides chlorine, soda and table salt from the brine. As of the hot ash from the coal, limestone is added turn the ash into cement. This way every single material that went into the power plant complex becomes some kind of useful product, except CO2: the coal's energy gets turned into electricity, industrial heat and room heating for winters, the coal itself turns into cement and CO2 (sadly that is not caught now.) Seawater is pumped in with the initial intention to be cooling water of the power plant, but it turned into a practical source of city water supply. As of the brine it is put into multiple uses after being concentrated at the power plant.
By far one of my favorite and most interesting videos D-News has provided me with so far this year. Just between the information provided and the way it was delivered, I really enjoyed this! Thank you...
Californians use 1500 gallons of water per person per day. *_CLOSE TO HALF IS ASSOCIATED WITH MEAT AND DAIRY PRODUCTS_*
*TELL THE MEAT AND DAIRY INDUSTRY TO HALT ALL OF ITS PRODUCTION LINE, IT TAKES 2500 GALLONS OF FRESH WATER TO PRODUCE 1 POUND OF BEEF!!!*
That would be a terrible idea. California products billions of dollars worth of agriculture. The state collects taxes from these sales. Sure we'd have more water, but taxes would have to go up to supplement the lost tax revenue. Not only that, but since now there's less food in the market, food prices will go up.
+bob174d *produces
Cows are terribly inefficient at turning plants into meat, just eat the plants
Or just create desalination plants
Yeah regulate civilization out of existence, that will solve our civilizations water shortage. Better yet, we should just all die, problem solved.
So eventually their problems will be salved.
pls, the puns, noo...
I'm so in love rn

Just curious, but does it look like this guys head is added on with green screen or special effects? It moves weird.
+Roman Fox Yes, SciShow is filmed in front of a green screen to easily allow different backgrounds for different topics/shows.
OK, stupid question time... Don't power plants regularly use fuel to turn water into steam? Could power plants near the coast use seawater for that, and then condense the steam into something drinkable? Presumably with some changes to the turbines, etc., to not contaminate the condensation with lubricants etc.
takes too much energy
I'm talking about water we already turn to steam.
You have a point, I wonder if there's not a solution down that line of reasoning.
They kind of do that on nuclear supercarriers. I mean, the seawater doesn't go through the reactor/turbine, there is heat exchangers.
Other forms of "cogeneration" is possible,
Where do you think the salt is going when you boil off all the water? You will have a big tank of salt very quickly.
Also high pressure high temperature steam is already quite corrosive on its own. Now imagine doing the same with saltwater that "eats" ships even when cold if not specially treated.
I live in CA. Quite possibly one of the most politically fucked up states in the union. Even the water is part of it.

Thank you for discussing this

When you guys stop growing rice in the desert and floodwatering other crops, we'll talk.
OOZ662 what state are you from?
Panda Man
Washington.
OOZ662 well there is nothing i can say thats bad about washington, washington is the best state in my opinion so i cant diss it, never mind
2:45 soo that's like... 21 bucks a month per household? How exactly is that a problem? Every household could pay that easily.
I know!
San Diego get's about 7% from the plant in Carlsbad , and that thing cost $1Bn to build.. so multiply that by about 14 if you want to get all your water that way. and it works out to about $5k for every man, woman and child. Granted the plant will operate for decades so you can spread it out but it's not cheap.
Of course this assumes you want to get it all from the sea and not just replace the missing water due to drought.
thats the cost of making the fresh water
But how can they make money on it? That's the real problem.
thats still chump change, especially if youre talking about water, the thing that all life on earth desperately needs to live.
i mean, im in the us navy and im primarily based on an aircraft carrier and the ship cost about that much to build, let alone its yearly cost.
Love how you explain and don't just state.
The Brien can be sold to companies that produce chlorine gas and make Sodium hydroxide. Since brine is electrolyzed to form NaOH and Cl2 products. Furthermore, if one has a mercury cathode one could also produce a mercury sodium amalgam to later produce sodium metal. All of which are very useful chemicals in the industry.
2:41 so a little over $20 a month per home. It may not be ideal but it is manageable.
You forgot about the cost of building one of these plants. Probably cost close to a $1bn.
It should be charged by usage. Farmers would be using a lot more than non farmers.
+Randy Randerson then Farmers would charge more for thier products, genius
Olvin Lara Why should the consumer in the valley pay for their usage of water instead of passing that cost to people who use the food?
gotta do what you gotta do.
02:13 Not true. In Israel desalination provides more than 50% of the drinking water, and this can increase to almost 100% even given current capacity. Israel's Mediterranean coast is 273 km long, meaning about 3.2 km per 100,000 residents. California's coast is 1,350 km long, meaning about 3.4 km per 100,000 residents. This means that with the same coastal utilization, California can provide the same amount of water to its residents, the vast majority of whom live close to the coast. Australia's desalination plants also provide up to 50% of each region's water demands, and their capacity can expand significantly.
This will free up the natural water sources for agriculture, but of course the long-term goal is to use treated waste water for agriculture, since desalinated water is considered too expensive for this purpose. In any case, getting water inland is really not that much of a problem long-term, but you need to make significant infrastructure investment. Israel's natural water sources are mainly in the east of the country, while the sea is in the west, meaning that for its desalination program, the national water company (Mekorot) had to invest billions into new conduits and pumps to reverse the general water flow in its system. California will need to do the same, because both desalinated water and waste water will now come from the west.
I think the reason we're not putting in the infrastructure like Israel has is because our community decision makers are motivated by profitability instead of building infrastructure for long term public good.
thank you!
Permaculture earthworks could drastically reduce the effects of drought in California if implemented. The earthworks like swales and key line design using a Yeoman's plow holds water from the rainy times of the year in the soil vs. channeling all the rain runoff into temporary rivers and directing it out to sea.
Or just stop trying to grow the most water hungry plants there are like pistachios, IN A DESERT!
And usa is called superpower.
Or almonds.
Or even better, stop letting corporations drain the few existing bodies of fresh water from said desert
Yeah just avoid adaptations to climate problems. And move away. Great solution.
Recycle heat from industry and power plants to vaporize that seawater!
👏👏
Solar desalination is usually a byproduct of solar power plants using collectors, where the steam is used to drive a turbine. So you produce fresh water AND electircity, to boot. Solar collection power plants are larger and more expensive than PV plants, but they can transform a larger portion of solar radiation than PV panels (ca 0.4 kW/m² compared to 0.2 kW/m²) into electricity
To sum this video up:
Maybe.
Thanks SciShow. Way to put.
Related question, in a solar desalination plant why not create evaporation flats at the end to provide salt? This is effectively how we have gotten salt deposits in the past which we mine for the salt, so why can't we get the water for drinking and the salt for food from the same source?
My assumption is that since salt is DIRT CHEAP, that wouldn't really make sense...plus this isn't _table salt_, it's whatever combination of random minerals (and microbes) is in seawater.
...Although there must be a way around that, if we've been doing that forever. I guess we used to just eat the rock salt and such, too??
+May your swords stay sharp! (mysss29)
The cost of processing the salt(for whatever purpose it is put to) would have to be considered in terms of disposal. Even if they make a loss selling the the salt I imagine it would be nearly as bad as if they have to pay for proper disposal. Though there is the possibility that it might be used for stuff like CO2 sequestration or even fracking...
*wouldn't
Ken Oakleaf
Ah, that's true. I do wish the video went into more detail on what happens to the 'brine'. I wonder what value the different other salts in seawater have....
omg desalinated water costs 20 dollars per month per home, too expensive, i'll just drink my own pee thank you.
That only covers the cost of electricity to power the plants.
not the cost of building the plant, or paying the worker's.
When I lived in Florida it was 120 a month
Just make the water and give it away and make the middle class pay for it. its a democratic plan if i ever heard of one, come on Obama, just add it to the health care plan!
for the brine, you can use solar power to basically disinfect and dry the brine, and filter the dry particulates for further recycling.
California has numerous 'ancient' riverbed fragments that if dredged and reconnected {with pumping stations over level faults} might transport fresh water through most of the central valley... it's 'logistical'...
Much of California's usable water is from underground reservoirs. Considering it is also one of the most populous states, its not surprising that resources would be getting stretched.
*Watching video about droughts* *Looks outside* It's pouring rain..
send us pls
plz help us

"I have a sandwich so world hunger doesn't exist" I know it's a joke but I think this is funny too :)
SoCal native here and I can tell you Cali has the most efficient drainage system available. huge storm water runoff channels, pipes you can drive into etc. basically all the rain for the year falls in just a few days and all that water is packaged up and shipped to the ocean. before us that water would quench the land and replenish groundwater for trees to tap into and bring to the surface for other vegetation. From what I understand the top 3 offenders are 1. runoff mismanagement 2. dredging the bay (killing the annual flood cycle) and 3. global warming
In the cayman Island ALL tap water in every home, condos and hotels is from desalination since 1989.
in QLD australia, we built a RO desal plant during an extended drought,
it rained again and now every one says it was a waste of money - hindsight maybe, but if the government didnt do it and the drought continued, we'd have no water
The way to do it is to use government money to keep the facility in place anyway. Its like a reverse power plant, you put in power and get fresh water, but like a power plant, its a big piece of infrastructure that you cannot build overnight. It needs access to the sea, needs to be connected to the high voltage electrical grid, and able to add fresh water into the water supply, so only few locations are suitable.
So i can think of 4 good reasons to keep it running at a deficit if the government can afford it: To buy excess electricity from nearby renewable producers of solar, wind, geothermal, to add fresh water to the system to keep supply up and prices down, to keep the jobs, and above all else: To have it when you need it next time. If done right its just an indirect governemnt subsidy for green/renewable energy, fresh water, and local jobs. There are worse ways to "waste" money.
SA did it too, I'm not sure if it's 'really' being used either
To be honest two thirds is pretty good for a desal plant.
But what's the demand?
theconversation.com/how-drought-infrastructure-can-help-us-get-through-floods-12056
we were close to 30% capacity in our main dam in southeast QLD - a city without water is not a nice place to live - en.wikipedia.org/wiki/Water_restrictions_in_Australia#Queensland 2006 we hit level 6 restrictions,
- they call it botched now, but iit nearly became our only option
Hey, let's live in a desert, fucking great idea right?
Wait ! now what about inviting some millions of illegals, and say the place is a sanctuary for them ???
What could possibly go wrong ?
??
All we have to is build Petr.... Wait, that was built 2500 years ago...
You can pipe the water 100s of miles away to farm land. They do that in Mid East. Plus Dsal would reduce pressure on water demands if cities drinking water came from such a process.
To SciShow. $25,000 a month for 1200 homes = about $20 a month, per home, for electricity. I would think that would be reasonable, especially with a water shortage.
I saw a bird today
it was pretty
i see birds everyday
k then
Interesting
Did you kick its ass?
Well why don't people just try to stop the global warming process? Oh wait this is a political issue somehow.
I like the somehow😄
Because a large subset of the population does not want to be accountable for their actions, and think they deserve everything for themselves.
Because it's estimated to cost 1.5 trillion dollars to cool the earth 1/20th of a degree Celsius. A lot more expensive than most desalination plants lol!
I'm pretty sure that global warming is irrelevant to the California drought. like 4% sure.
Climate change would increase rainfall, but only in certain areas. An simplified way to think of it is wetter places will get wetter, drier places will get drier.
man how i would love to be able to go back to school and learn more about this so i could help out. a dream job.
the brine from desal plants is quite mild. Less than 2x the original salination levels. It is frequently put back in the ocean, and done properly can be quite safe to do so.
Perhaps if oil companies had not been permitted to stifle solar energy development and adoption, it would now be available. A state which has too much sun seems lie the logical choice for solar powered everything.
yeah and let birds die like ants under a microscope great Idea
well, the whole world economy is based on oil, the whole world geopolitical power divisioning is based on oil control, USA whole might is based on oil and numerous military bases around the world that guard it. If oil gets to be useless piece of shit thanks to advanced solar energy it will nullify USA influence and achievments. Countries would become truly independent with their own infinite solar energy, the fragile balance of powers will crumble and world chaos will begin, all out wars, all economies fall, famine - and all that not somewhere far but in USA too.
+Random Made birds dying versus everything on earth dying. Not too hard of a decision
which is why its best to let the market move over to solar instead of making a legal policy, that way it is a gradual change and the worlds interests switch to something else. Changing the world to solar might be the quickest way to defeat ISIS, or atleast put a large dent in their pockets.
Thats only if you use solar plants, It would be a far better idea to have solar panels on your roof with a battery pack in your garage, that way its near impossible to take out the grid because each home is its own grid. (short of an EMP) atm half the grid could go down at any time, it has 0 safeguards for cascading failure like what happened a while back and people were without power for a long time
So I think the obvious answer is a desalination plant powered by a nuclear reactor. This is 2016, can't we do that safely?
A nuclear plant, probably right on the coast to be close to water/cooling, in the middle of a major earthquake zone. What's the worst that could happen?
dude, it's been more than a century since Tesla invented the high voltage AC transfer to a long distances without significant losses...
Tesla invented nothing like that.
+superdau I believe Tesla did invent exactly that. It's odd to me that in the age of information nobody can be bothered to spend 2 seconds searching google before they say something about things they know nothing about. Use your resources people!
Use your own advice before commenting please. He did not invent AC, only improved it.
"The first alternator to produce alternating current ... constructed by the French instrument maker Hippolyte Pixii in 1832."
Tesla was born in 1856.
Dude the timing is real
I live right by that desalination plant in Carlsbad. It was a power plant.
ANYONE HERE LIVE NEAR CARLSBAD CALIFORNIA WHERE THERES A DESALINATION PLANT
Yup
yes i do
Heyo
Exactly, I saw this video and was like. ¿Qué?
Just leave the water in the sun. It'll heat up there.
😆
And when it dries up from that, we can get and sell sea salt.
Plus if you add solar panels and submerge them, you take the heat that is lost from the solar panels and put it into the water. Fresh water and sea salt at later stages.
@@alantonix213 and where do you think the water goes if the sun heats it up?
I actually did a paper on this in a Master's class I took several years ago. Some countries, like Kuwait, get the vast majority of their water from DeSal. Those countries also use water per capita like it is going out of fashion, to the tune of 600+ gal/per/day, in the US it is between 200-300 on average depending on region. Australia, which also went through a water crisis "solved" their problem through water conservation and education of saving water, they average about 100 gal/per/day. The main problem with DeSal, like you mentioned, is energy. Its not so much that the water isn't there, or that the technology can't support it. But it is the vast amount of energy needed to undertake the project, Kuwait directly controls their energy costs so it is not as big of a problem for them. They also don't have many other options for freshwater. CA, and the US in general could benefit most from water conservation techniques, while researching clean energy to power the DeSal plants for the impending water crisis as population increases.
Lease the laguna salada from mexico and pump out the brine from the salton sea, then pump in fresh seawater and let mangroves desalinate it through transpiration
Why not just fucking hydroponic farming and use 1/3rd to 1/10th of water used by normal farms.
***** No it is growing in water instead of soil. It allows you to vertically grow, but is not needed.
***** Hydroponic plants are just as cheap if not cheaper
+KamiltheCamel And how much will the power and building materials cost?
[to Connor Peake] I think the idea that you wouldn't NEED the thousands and thousands of acres for that productivity, is pretty much exactly the point?
Ice pascual It doesn't matter power is cheaper than water. They can use solar power. Also BTW do you think normal farming uses 0 power? Like hydroponic doesn't use that much more especially in CA when the light is free and you don't need grow lights. This is a major solution, but as normal people hate start-up costs
Oh crap a "Natural Disaster" I feel triggered so you can't monetize this video.
I made the suggestion for this video, thanks for the shout out lol
I We thank you, We thank you All ❤️🔥 😊 🙏🏻
i remember back in the late 90s israel offered a new desalination tech. to california for super good price but the anti Israeli geniuses turned it down for whatever reason. things would be much better.....maybe it is time to revisit our middle eastern allies for help. they have it perfected by mow.
And it never rains😑 it has been 5 years since i have seen snow in California... I moved to California 5 years ago...So yea
It's all your fault
"They say it never rains in southern California"
it rarely rains
brick house
It's a song lyric.
+Gamesman01 Tony Tony Tony lol. I thought of that when I went to Disneyland in LA last year. The people around me of course were happy
We can also make our own solar distilleries at home. Not like we don't have an abundance of sunlight or anything 😉 this also would be a great way to offset individual impact on the grid. You can also use the sun to heat your water reserves as well. Just think, the less you need your water heater the more you save on power. Food for thought anyways. Great video guys! Love the show 👍
large magnification domes combine with solar electronic heat would work really great
plus the brine could be turned into sea salt wich could be marketed and sold
Lol just drink water bottles, duh
Water bottles in California are bottled in California, so...
How will you water the crops? How about the wildlife? Where will you get the water? If its local you aren't solving any problems. If the water is not local then you need to add the shipping costs, the energy cost of recycling all those bottles which assumes that they are recycled. If you try to pipe it in then you have some serious mountains in the way. I'm not saying it's impossible, its just impractical.
Sean Peacock I was being sarcastic
duh! How can you not love when carcinogenic plastic leeches into your drinking water?
We do it in Perth, Australia as we have been in drought for 17 years
desalination plants could sell the salt, as sea salt for cooking if it meets health and safety, or maybe road salt if it doesn't, it wouldn't supplement all of the costs, but it would do something
We're gonna build a well, it's gonna be yuuuge, so deep it'll make your head spin.
Build a well! Build a well! Build a well!
I've been wondering about this a lot lately. Thanks for making this video. What do you think about FLIBE reactors to desalinate water?
I did a research paper on the California drought in college. Desalination is definitely viable and can be a supplemental source as said in the video, but the real long term solution is to improve the efficiency of the system by recycling waste water. Countries like Singapore that have implemented water recycling keep their reserves above 90% full even in severe droughts.
Nice key on that drought map
Ugh we're gonna need a lot more than that considering that water tables around the world are being used at a surprisingly high rate(above replacement rate)
Could send clean soft water (has cloride via sodium chloride already in it) from the Atlantic to every home, then run soft / salt water to showers and toilets, then people have a small distiller at the kitchen which disinfects and removes salt for drinking, about a gallon a day per adult.
If the shower water is too soft people can buy a water de-softener, or whole house reverse osmosis system
California's agriculture uses so much of their water. MULCH is a huge part of the answer. A properly mulched garden/field will use 10% of the water as one with bare soil where the water is just evaporating and the microbes that would help store the water are baking and dying in the sun. MULCH and mycorrhizal fungi increase water storage immensely. But using glyphosate kills mycorrhizal so effectively, even at 50x more diluted than standard dilution. Water saving solutions are out there, people just don't seem like they want to change.
The Carlsbad desalination plant makes the water warm it's kind of nice in the winter
Can you do one on cerebral aneurysms? I had one rupture at 19 and would love to learn more!
This is the second time I see this comment like
Thoughts regarding the Drought crisis :
From what I have read water generally needs to be filtered first and probably needs to be distilled as well. As far as I can understand mountains of charcoal if not "activated charcoal" needed for filtering water.
Controlled burns to minimize chances of forest fires? How about harvesting trees and shrubs for charcoal and mulch?
Practically it seems like the USA should develop dynamic water management in every county and every neighborhood.
In water shortage areas like California dynamic methods of salvaging water and storing water as seen on desert homesteads should be developed.
Even in areas that are are not experiencing water shortages should harvest any fresh water and store for emergencies. Fresh water should be shipped from areas with more fresh water to areas with water shortages. Water needs to be salvaged & harvested from rain and fog.
Perhaps there is some way to dam up the Lake Pontchartrain to start turning it into a fresh water Lake .
Large Farms should try breaking up into smaller farms 1-5 acres. Small Farmers can then conceivably manage Water and Agricultural development in a more dynamic manner.
It seems that millions of passive solar water distillers should be manufactured and organize utilization of these.
Mountains of charcoal probably needed for water filtration.

Thank you
I like this guy, his voice is calmer than Hank's
The whole concept of water rights, especially in drought stricken and prone places like in California really boggles my mind
Here in Australia where we get multiyear droughts every decade or so the government has encouraged and subsidised the installation of rainwater tanks and by law (where I live) every new house needs a rainwater system installed to meet the building code standards.
Most of these systems are just used for garden irrigation (there was also encouragement to replant lawns with drought resistant varieties), toilet flushing, clothes washing and maybe showering/bathing. Although some houses are also setup to collect and recycle their greywater
Yay! My SOMETHING SOMETHING was mentioned!
hey scishow i have a question if the pencil i was holding in hand was extremely radioactive would i be able to tell? would it feel warm and tingly or would i just end up sick days later? thanks!
I saw a video with a guy named Kirk Sorenson who proposed that extra heat from a LFTR(a type of liquid thorium reactor) could be used to desalinate seawater.
LItterally was talking about this is class then it gets uploaded
I'm from California and we are definitely in a drought please help us out and spread this video for awareness! good lookin
Easy solution, use the heat from a nuclear reactor to act as the thermal component in the flash approach. Since you don't need to convert the thermal energy into electricity you could probably get a very good efficiency out of it.
Sadly, I suspect the stigma against all things nuclear will prevent the suggestion from being put into practice.
Nuclear is satan according to green(greed) energy minded groups in office.
On our island of curaçao all our water comes from the sea and it's extremely clean and great to drink
Hi there is an Australian inventor (can't remember his name but it starts with a Z) who devised a method of having a double channel going inland with a glass top. As it flows it evaporates from one channel to the other. At the end you get clea water. Easy
How do you get rain? Evaporation now put it in an evacuated system and get water at high volume and low cost sunlight heats hotboxes with plumbing it goes to the expansion chamber becomes steam salt falls out then goes to a cooling chamber where it condenses to pure water, cold intake water is the endothermic source for condensation you can run it on the expansion rate of hot water to pump the system with one-way valves.
How about building an aqueduct from the Mississippi River beginning near Memphis and ending in southern California? Could also help Texas, New Mexico, Arizona, and Nevada along the way!
Great video, but what would they do with the left over concentrated salt water or salt? I know it could be purified and sold as salt, but salt is cheap and it may cost more to process and sell the salt, then it would to just dump it. The problem is, you don't want to dump it on land, but you don't want to put it back in the ocean, which may make the immediate area where water is taken from, saltier, making de-salination less effective. I suppose they could separate the extraction and dumping by using distance and timing, but i'm not sure. It would be funny to store them in large barrels and bury them like toxic waste.
@scishow how much of CA water is used for fracking and oil in general vs agriculture?
reforestacion and small retention
When the coastline is forested, _it rains downwind._ If we want Southern California, Arizona, and Northern Mexico to become _Green,_ we'll need to plant coastal forests from the southern tip of Baja all the way up to San Francisco.
Mangrove forests would add to this effect as well. Also, a chain of artificially constructed islands, each being well-vegetated, would further add to this effect as well.
The reason Syria and Northern Iraq are now desert areas, is because the Levant was heavily deforested just before the Bronze Age collapse. The Ancient Egyptians imported massive amounts of cedar wood from Lebanon, though, they reported the first shortages around 2300 B.C. (don't quote me on that exact date).
The Akkadian Empire was the world's _first true "Empire,"_ because they were the first to permanently staff a professional, full- time military, as opposed to hastily arming conscripted farmers in times of conflict, which was the standard operating procedure for all other civilizations.
The Akkadians were able to do this because of a massive agricultural system, that sprawled all the way up to the foothills of the Caucusus Mountains, with endless grasslands producing grain for them.
Once the Deforestation in the Levant became severe enough, the droughts began further downwind, and starved the empire right out of existence, along with all of its contemporaries (who were simply "civilizations," _Not "empires"_ ).
So yeah- we need to start planting trees en masse up and down our western coastline.
We could add a third bin to the curb in front of everyone's house- compost. If we had a nationwide compost collection service, we'd have the needed material to turn sand/clay into black soil. Those artificial islands I mentioned would definitely need that, and to create mangroves, we'd have to use dikes, rocky barriers, and partially submerged levies to create areas where soil could actually stick around, even whilst being submerged in sea water and subjected to tides.
We'd also be sequestering absurd amounts of Carbon too, and we all know that rainfall is more reliable in a milder climate.
To further that specific cause (cooling Earth down a bit), we'll need huge sheets of reflective tarps, floating on buoys, in the Arctic Ocean, to help sea-ice form earlier in the year. Once the ice forms, we move the tarps, because ice reflects sunlight all on its own. It's just the liquid water that's a problem- it _absorbs_ solar radiation in the form of heat, causing a runaway melting effect.
We could also use huge ships, surrounding the tarps, to block swift currents. If the water is moving less, and the sunlight is being reflected, we'll get that seed-ice by Autumn, and then we can move the reflective tarps to the edges of the ice, to help it grow fast.
If this ice project is started on a shoreline, we could build permanent dikes, to deflect currents, and create a baseline of coastal sea ice that never melts.
Space-mirrors aren't a viable option yet, _so giant tarps it is!_
I actually got the tarp idea from Switzerland, where they cover their glaciers like this, to slow down melting.
Have they considered using the motion of the waves for part of the pumping or pressure problem? Either as a direct pump motion or to generate electricity? That might make it more cost effective. Just a thought. Goes back to my childhood in the 70s when they were considering all kinds of renewable natural energy sources.
I have a idea. Build a satellite in space in a low geosynchronous orbit. Have it convert that uninhibited solar power into a tight beam laser at a desalination plant that can focus the light onto a pool of sea water. The water will steam up and presto fresh water from a constant source of energy. Pump the brine out of the bottom of the pool. Turn that brine into salt crystals and build stuff with it, or sell it to hunters for deer bait.

Can you please make a video on cracking joints? I need to show it to my mother :))
I'd suggest that you use desalination only when you've reduced your water use as much as possible. Could you maybe do a video on the methods typically used in dryland agriculture to minimise water use, new technology and how that relates to CA?
Crazy idea. Build to plants next to each other. One a solar desal plant and the second a solar plant that melts salt and in turn powers turbines. The plant with mirrors focused on a point. The desal provides all the slat you need and eventually the salt power station provides electricity. Any excess power can also be diverted to homes and local communities. Thoughts?
Fun fact, in the virgin islands (U.S) the municipal water is unfit for human consumption. People have rain water cisterns attached to their homes and drink bottled water. Most resorts operate their own RO plants. The EPA is infamous for shutting down resorts for mismanaging their RO plants but do nothing, for or to WAPA, (Water and Power Authority)
You can water crops with saltwater. Add a little sugar and food coloring, call it Brawndo, then you can water crops with it. It's what they crave.
