real poverty is a cornerstone of low carbon energy generation. but stems have become bigger and more controversial. yet the water pressure in our pipes goes must be on tap. so how does want to get to our attempts in the 1st place as a commercial water supply system bring the waterfront? this source as sweet sites delivers it to people. the majority of countries comes out of your time, then it's taken away. treated then put back today and this is an initial jeremy. she and her team had examined the research on in pipe turbine technology. this process is very energy intensive. you need a lot of and i see is waterfront location to location, to treat it, to distributed among people. some cities are lucky and they have lots of it comes from higher altitudes. so gravity does, most of the job and less energy is needed to transport. but in berlin, london, odella, for example, the water supply system relies on pumps. and in some countries in the middle east,

the water needs to be celebrated 1st. that observes 4 times more energy than conventional voltage infrastructure. we also need a strong water flow, so it doesn't take 10 minutes to fill up the firewall to it doesn't come from reserves. at higher altitudes we need pumps. but stop pipes 1st and due to too much water pressure, reinstalled the wise. it's called pressure walls. they basically remove the excess of pressure. that is where all the juicy energy is wasted and varying pipe takes on it. you can come in at turbine in the pipe, would convert the excess pressuring to electricity. you know, what happens when a turbine spins right? it generates good, all the electricity let's find out how this works and principles. i am setting up a little circuit, the clinic, depth, and cage. it's to harness static just be generated from this tiny walter turbine. i can charge of battery to run a multiple turner light and charge my phones with it. this is of course, just

a tiny, tiny water turbine. we can still bigger one so that it would, there is an abundance water flow. the energy that can be created depends on the turbine, as well as the amount of pressure in the pipes. if you really don't have a solid number to say this is and this is how much energy we can generate. but the reality is, the, the cost, the world, the baby have felt that water systems, water is moving from location to location. and it is, it, it can potentially be used to generate and are see different studies give different estimates. one report for the us department of energy estimates that in pipe turbines could produce 1.4 to one gigabyte of electricity across the us. that's quite that conservative estimate. it would be enough to power at this $1000000.00 homes in the us for more than $10000000.00 in india. yes,

it housing the us to is this 10 times more than one in india. but that's another story. other studies are more optimistic. all the research that from the usa is up to $43.00 gigabytes of energy per year, could be harvested in the state of massachusetts along if lots of companies created their own energy using their infrastructure, the price of water control and that, that a great piece of news is that these turbines can be retrofitted without harming the environment. the operators love it. powering the charging stations. this is greg some of the he's company has been charging customers in pipe electricity. how cool is that? yeah, i mean the biggest challenges that we have is that it's new and so. ready anything that's new, people always want to understand what impact is on their operations.

but when, whenever i do a presentation or whatever our team is presenting to people who. ready are knowledgeable about water distribution, they get, they get it immediately, is the cost is in it a thing, and these new systems i'm not getting sent to wise. in many places. people can be cover the cost in couple of years or less than that case. and that's what we have seen, obviously, it depends on the scale of the project, as i said, the cost of electricity. but then again, you need to have enough upfront capital to be able to invest in these systems and then have time to cover them. this might be tough for small businesses, but the municipalities and big companies have a responsibility to step up. countries in the global south have a great advantage as they are currently expending their walter systems. india is diverse, largest consumer of groundwater, and most of its cities don't have constant running water at the moment. but the country is planning to invest hundreds of millions of dollars to provide its huge population with pressurized water,

247 subsidies that are already on board with this technology. take portland, oregon, for example, harnessing the power of in pipe water to lights up their streets and power, essentially the public and fist ect. and the eastern 3rd the of the are but couldn't use already generating to media and lots of electricity and sending it to the local. great. and it doesn't stop there in san francisco, money cape them, they're all catching onto the potential of the attempt energy flowing in the streets. you could say that in pipe technologies in energy hero with a low profile, it makes the most of what's already in place. while reducing the reliance on fossil fuels with 0 to very low environmental impact. 7, right? well, it isn't in the are facing dealt like conditions. i'm serial scarcity off what this comes with grief consequences. so the local communities, i'm so the closest to you are up to, is witnessing for in water tables. and this has its own consequences,

likely seats in northern it to me she's season onto the locals. is a familiar face, a lake got the gen column, of which she has been faring torres over at least largest lake for 40 years. but never before has you seen the lake like this in spring? where there once was water? now people can walk to the island, the middle school saw last year when the lake was pretty full, the water went up to over and adults waste line very well. so, but i let you in to get anything good more and the situation is very serious. so there's a lot of all we can do is wait and helping lorraine from the make, the why the level rise again, doing it so bad news for his water taxi business fraud

or at least 40 percent of the people preferred across on foot. and then when they went to head back this summer, tired of walking and take my boat instead. this is the only boat he can still moore at san diego island. his 2nd cutter is stuck at the port. no one chief knows remembers a time when the water level was as low as this. not at this time of year. the southern tip of the lake investigator delgado ilario medical on the records, the water level. every morning. she works for the regional water authority at his pest all on the bus side of the level is 60 centimeters below average compared to the previous year. so the, the, uh, the terminal around this time were normally at one meter in 20 centimeters over the defined 0 point, a toyota method this year. read just 47 centimeters, pasano off into sound walk. what on the set, the to and to me, 3,

with so little water, the power plant, a few kilometers down the river has stopped to just beyond eliza, solely on say them from this spot. you loud kalani controls the water flow from lake top desk. do you disagree with the part of the year? i can see the long as in check, but nothing is blocking the barriers. think us about the quick cause. i mean, you've got a gummy, everything's fine here. still. she opens and closes the locks. this water is supposed to flow from here onto the fields and farm and south of lake god. uh. but there isn't enough of it now. of course certainly by law, etc june. we normally don't reach this level until mid summer and finds a cale fletcher for that audit. it's almost what i'm trying to do. the impossible to sort of the, the, we have to strike a balance between the needs of residents living along the lake and farmers in the valley, out of the colleges and the valley. that's no easy task. and mistakes are high

. last summer's heat, wave cost farmers 6000000000 euros. just east of like got the you're swapping farmer more and they'll come up. site is very worried about another drought. this time, most of us on the fields are almost try it out now already you can see it just by the dust that gets kicked up when we till the soil combine. yeah. me through the mentor. i'm already on the current situation presents farmers like what in know with tough decisions. i better to be see mean it does actually time to plant cries, but i don't even know what i could plan to size. so the core in, for instance, takes lots of water if you know, if you know, but i don't know if we'll have enough water from the irrigation system until harvest time of the, i mean, we're clearly see me effects of global warming. the farmers and regional government

have taken one 1st step. they used you funds to renovate and seal the 1st section of the water channel. this channel is over 48 kilometers long, and waters fields and meadows throughout the region. a follow as you need to, once the work is completed in 2 years, will save about 150000000 cubic meters of water a year. give what that means, more water for our seo. so according to an italian research institute, 50 days of continuous rain could change the situation. but the weather forecast is predicting sunshine over the coming weeks and they've got it. the meaning chief and his water taxi aren't the only ones who might face a tough summer. water really is something that we can often take for granted, but often engage annuals and get sustainability is very important. and today we learned about several ingenious ways of doing the same. but you let me know what did you like most about today's episode on what would you like to see more of you

can email us or right to me directly on my twitter. i will see you next week until then take care goodbye. my gosh, the,

the, the page, the beginning of a story that takes us along for the ride. it's about the perspectives culture

information. this is the, the news w. mine's not just under the other day. so much is happening all at once. we take time to understand this is the day in depth look at the current news, events analyzed right? experts to come to critical. i think yours not just another show. this is the weekdays on dw guardians of truth. my name's jumped into and i have paid almost every price of being enjoying this in a country like to tease taking on the powers that be the risk every thing

they want to me and they try many times during dar this activist journalist and politicians living and anxiety, what drives them to the too much for my shoulders, but i have to hold this way because i'm responsible for the future. our country for the people, far behind the bus, the courageous effort against corruption and political crimes. in our series, guardians of truth. watch now on youtube dw documentary. it's all just practice or is that the name to base in brooklyn, lithuania, 7 months before russia attacked ukraine, affility documents, daily life, the town hour. the people live for o'clock dealing with the growing tension.

change their world currently go in and the insight starts joining on dw, the . this is the, the news line from ballot tough talk against the wagner group from russians vladimir putin. he says that the most in there is who let the fails. mutiny were entirely funded by the russian states and profited from government contracts. and on a trip to south africa, germany is foreign minister says the war and ukraine is what.
