Hello!

While you’re here maybe you can answer this or make a video on it. explain to me why we can’t use solar towers to evaporate water to purify it while also generating electricity at the same time.

Oh yes, I know how to use my billions to stop climate change. Let's sell a book, and make even more millions

Ooh! It's Grady! I have a minor issue with the water tower listed at 2:59, and your water hammer video has all the background you'd need to understand. Basically, this video lumping it in with water towers without some caveat is slightly burying the lead. Since there is no tank on top, this tower is not very for storing significant amounts of water. The key is finding where this style is built: near pump houses built early on in the 20th century. Back then municipal water was pumped by giant steam pumps, rather than modern electric impeller style pumps. Their enormous pistons created constant pulses of pressure that would tear apart pipes without some way of letting off all that energy. In your video you talk about surge arrestors which use an elastic bladder to absorb some of the energy of pressure changes. You then mention traditional tank style water towers being able to absorb the surges by driving the water up when the pressure increase, and which consequentially also normalize the low pressure valleys by the hydraulic weight of the water coming back down. For reducing water hammer, the diameter of the water column doesn't really matter (give or take friction and resistance) as hydraulic head is simply a measure of how high up the surface of the water is. So, you really just need a pipe connected to the water network, sticking up out of the ground, open to the air on top with some screening to make sure bugs and worse debris don't get in. Make sure the pipe is taller than the maximum hydraulic head you expect so none spills out the top, and you have a standpipe. Now, in some places the standpipe is just iron pipe standing up out of the ground, and I do love when a thing's name describes exactly what it is. But some places decided to pretty it up a bit, such as the Chicago Water Tower shown at the time listed in the beginning of this increasingly long comment. And then there is my favorite, which is also a standpipe and not a "traditional" water tower: Milwaukee's North Point Water Tower. I mean, just search for some images of this fairy tale inspired piece of architecture. And to top it off, in the mid 80's an artist made a 30 foot long dragon sculpture that perched on a window of the tower for five days. Which brings to mind my actual favorite version of this water tower, which unfortunately doesn't exist in this reality (yet.) In my memory the dragon has grown larger and larger like a fisherman's prized catch until now I distinctly remember an elegant, regal copper dragon completely covered in patina from the years it spent there, body curled up around and around the tower like a powder blue Wat Samphran, watching out over and past the horizon of Lake Michigan, scanning for... hydraulic transients, I guess? And I think the world would be a better place if more municipalities dressed their infrastructure up with this level of whimsey. I'll also give some points to those communities that paint their water tower tanks with giant smiley faces.

*water engineering mentioned* Practical Engineering: Who summoned me?

I, too, commonly ask people what their favorite water tower is in a common conversation

We don't really have water towers in europe ¯\_(ツ)_/¯

@@moonam8389There's plenty in Sweden. I've also seen many in Poland and other eastern states. I think I've seen a few in the Netherlands as well.

@@moonam8389 there is a lot in Poland, some are quite old. Here is some examples from polish Wikipedia pl.wikipedia.org/wiki/Wie%C5%BCa_ci%C5%9Bnie%C5%84#Galeria

Hallo

Dude that's brilliant. But what about sink pissers?

@@germanogirardelli those people don’t even deserve access to clean water

If you use the sink only for washing hand that's fine, but if you use it to wash all sorts of stuff then the tank will get very dirty very fast.

Like the desalinate idea

Agree with all of those ideas. The main issue though with charging farmers water at cost is that it would most likely bankrupt 99% of farmers. I think the way we think of agriculture needs to completely change. We need a lot more farms just at a very small scale, that way peak efficiency can be achieved.

But if you charge farmers more you, they have to charge more for their food to stay profitable. Meaning that the price of food will go up, not everyone could afford. And the government could never pay for it either.

@@EglomHistory When the price of water is low, farmers use too much to grow thirsty crops such as alfalfa, rice and almonds. Taking too much water from underground aquifers caused the ground to sink as much as 30 feet, destroys the soils because of salt accumulation and farming land displaces wildlife. The Central Valley has good soil, plentiful sunshine, but not enough water. These farmers that damage the environment need to go out of business. Higher water price will force farmers to innovate (look at Israel being to grow food in the desert). The cost of our foods must include the damage to the environment, otherwise, soon, there won't be an environment left to grow foods.

@@gr8bkset-524 farmers have to already maintain their lands environment or they can’t make it profitable. I see that you mentioned you live in the Suburbs of Los Angeles in another comment, well I live in rural Alberta both my grandfathers were farmers. And not everyone could afford the raise in the cost of food. The farmers are more important to our survival then Bill Gates, Greta Thunberg or KZfaq’s: we should respect them not plot to put them out of business

I think a lot of Texans are wondering about this at the moment.

Answer: A private company or a legal entity owned by the central government or local municipality generates electricity at a power plant that is fueld either by Coal, Oil or Nuclear or they use a giant wind farm usually located a few miles at least ~10 miles away from the city border or they'll use solar panels (wind & solar are extremely uncommon) or they'll build a dam on a usually large section of a river which is generally located at the edge of the city. Most cities then send this electricity from the source to a transformer where it then travels through large pylons to smaller transformers where it is then sent through smaller pylons to individual buildings either above ground travelling through wooden poles or under the pavement/sidewalk. Some cities like London will build dedicated tunnels under large and wide rivers so that the grid can span both sides of rivers such as the tunnel under the River Thames in London. Most electricity in cities is generated by coal, oil or nuclear in plants in industrial estates in urban areas or just outside or on the city border where a plant failure will do less damage but will be further away from consumers of electricity . Most coal, oil and/or nuclear is transported to the power plant by rail using either dedicated frieght rail lines or on branch lines or they'll transport by road using a truck/lorry powered by Diesel (in most places), hydrogen or CNG or in former soviet states such as Ukraine they might use electricity by use of trolleybus wires and with oil specifically they'll use an oil pipe for the most secure method of transporting the fuel for the plant. Specifically in Texas, there is an electricity shortage because eco-communists like Bill Gates or Greta Thunberg pressured the Texan state government to end the use of "non-renewables" which means anything that isn't wind or solar and whats happened is that the big storm they had, has covered all the solar panels making them unusable and the the wind turbines have frozen up so they can't spin during high winds and only a few years ago they had decomissioned some (I think it was nuclear but I'm not entirely sure) power plants that didn't use wind or solar as a source and now they can't generate enough electricity to the grid which is something that's been going on in Calafornia for years its just that in CA, they started importing electricity from other states despite the high cost & low efficiency rates of doing so...

@@wclifton968gameplaystutorials well damn are you a lecturer? 😂

@@bishbosh4815 nope. This is all stuff I've learnt in my own time and some of it was in GCSE geography but most of it in my own time. An extra note as to whats happening in Texas is that I've heard that one of their nuclear plants wasn't prepared for the winter storm and so that has also contributed to the electricity shortage. I also gave this video a thumbs DOWN due to a William H. Gates sponsorship, a man who wants to depopulate the earth and usher in global communism.

@@wclifton968gameplaystutorials you're not a student even then?

you mean a aqueduct? they are still being used. at 5:27 that is how they often look like even if they do get higher of the ground if needed.

In one comic-book adventure Asterix the Gaul passes by one of them being built and says, "The Romans are ruining the countryside with their new construction!"

This video titled "How privitised systems that rely on a price/demand model ultimately only hurt the poor and benefit the rich"..? :lol

You beat me to it

@@AshLilburne price demand model? Read the DOE's order #202-21-1 from 2-14-2021 stating extra energy couldn't be generated for under $1,500 Mw/h. That called a govt planned, price fixing, bread line venezuelan economy

Desalination, ‘nuff said

👁👄👁

my hometown :) came here to make the same comment.

@@din6040 Haha, same!

@@din6040 I grew up about 40 miles west of Roch so I spent quite a bit of time there too. Good times.

How would you deliver that water across Europe? How much would be the cost of setting such a cross-region infrastructure? Think twice... how many people live in Slovakia compared to entirety of Europe? When will the underground water run out?

@@David_Journey not that difficult a lot of networks are already linked.

Yeah we'll be fine until we get a constant stream of climate refugees that will make 2015 look like childsplay. Although I'm less worried about the refugees than the nazis and other extremists they will give rise to

Wouldn't it evaporate within 2000 years?

12ken It probably won’t, unless something happens to the water output into the body of water. Otherwise it would’ve evaporated 2000 years ago.

What part of Texas though? Panhandle water definitely tastes different than coastal water than does the hard hill country water.

@@Wells306 as someone who has been to many different areas in Texas, I can confirm this.

​@@Wells306 I'm talking about the current water crisis. Most of Texas either has no water at all or is under a boil advisory. Where I live in Dallas the water is unsafe and smells like sulfur.

@@realjohnsomeone Most of the time the water is of pretty good quality, but all the pipes are bursting in texas right now.

I'm in East Texas. The source in my town is an aquifer, but in the nearby city it's a man-made lake and recycled from waste and tastes so terrible you can even taste it in the drinks from fast food soda machines and sometimes even the food.

In Zichron (Israel) we have a giant mural in ours and it's super old, it's been there since 1882

Chek mate😉

We have Mountains

Former RochMN resident here, I love that weird thing.

mn has all the best water towers - lindstrom (in vid) and rochester

Desalination creates other environmental issues, such as disrupting and killing local marine life. Also it's extremely power-intensive. It could be done in a green way with micro-nuclear power plants, but often these urban areas are spooked by nuclear energy and vote against it.

The bigger problem is that it's much much much more expensive than piping in natural freshwater

@@buddabulletproof And? We should pay more for water. It isn’t infinite

@@razzy1 sure. Just saying that cost is the reason why desalination instead more widespread. Maybe we shouldnt build megacities in deserts, or have agriculture in Southern California, either

@@buddabulletproof yes thats true, but we also shouldn’t be eating so much meat. Currently if the us switched completely over to just eating vegetables, it would only use the size of 1 of the smaller states, and it would use much less water. As of right now the us uses like half the country for meat production.

If you live in Milwaukee, I know you aren't saying "I don't know!" to the question "what is your favorite water tower?"

@@UrbanPanic North Ave water tower has that classic stone castle look to it. I think it's just for display now and no longer in use.

Zzzzzzzzzzt......and you mucked up the entire grid by not investing in key infrastructure protection measures. There goes the electricity, now those water pumps just failed, the oil refineries are now stressed. What are those poor fire fighters going to do? Let the large apartment burn. Smooth move Exlax.

He's too busy buying up all the US farmland...seriously, he's the largest owner of private farmland in the US with 142,000 acres.

I like this channel and this video, but, yea. Hard pass on Bill Gates, his book & his opinion. I understand the need of sponsors, of course.

Not a lucrative business venture. For many billionaires philanthropy is just a way to get good PR and a tax write-off

Use it as road salt.

Step 2: dump phosphorus into the lakes.

step one - build desalination plants step two - if you do not have ocean front property build a pipeline to the ocean

What is them?

grass is the #1 most cultivated crop in america. no wonder they're like cows.

@@michaelmichael2382 water supplies.

Not only Americans use water supplier for watering plants

@@michaelmichael2382 this is true, though grass (at least as used in most lawns) should be a much lower priority than it is. Also, When you water it is super important. Late evening is best. (No risk of the droplets causing lensing effects that damage the plants, And far less water is lost to evaporation.) Also, most other countries have less lawns than the USA, at least in areas that don't get enough rain to support the grass naturally. More proper farmland or high density housing, less suburban sprawl dumping huge amounts of water into unproductive uses like keeping the lawn green in the hottest part of the year (grass can, generally, survive the dry and heat of summer (in climates where summer is fairly dry), its leaves just go brown and dead in the meantime. But that doesn't look nice, so for maintaining lawns enough extra water is expended to simulate spring and autumn rains. Which is very wasteful.) Watering the plants that will actually die otherwise is perfectly reasonable (well, unless you've chosen Particularly unsuitable plants), likewise for food crops. Lawns, though, are mostly pure vanity, and in climates that don't naturally support them, utterly wasteful.

Have you visited the Inland Empire? (San Bernardino and Riverside counties) I’m originally from Riverside and a lot of families have pools in their back yard. A pool on a high rise is actually efficient when you consider the number of residents per gallon of water used.
