from advanced c, i, systems climate change is the new frontier of so from our series continues on since september, 1st on d, w, the y goes in pakistan is feeding the joy of books and the is the hope for los angeles, many homeless, the ends could ocean's souls on energy needs. the

almost 40 percent of people in pakistan lives below the poverty line. aaliyah knows i me too well how tough matches were on the beach of karachi unpack. it stands a reading and see sure. it's a long weekend. the fun on the waterfront for pakistan's middle class, the country is facing a crucial test. we can sense that here. nobody believes that anything will change quickly and fundamentally after the election. if you're a guy, thing with a heart goes with the problems with these things. so if you are going right i didn't show up on the evening before, after landing, and the 25000000 inhabit at metropolis, we realize what the norm is. challenges any future government here in pakistan would face its only rain for an hour before arrival. and large parts of the capital

are practically underwater. even the next morning, the water has still not drained away everywhere. and then narrow streets of karachi is historically already district. we want to know what people expect from a new government. as a very few foreigners come to this district notorious for drugs and gain crime, we are immediately surrounded. everyone wants to tell us something. what we need here is like tricity water, gasoline. i mean, that's all we need here, but can we help our selves with that's what we need. might be a standing thought. wants to show us something that they were really proud of here. we follow him to a place that disproves all of our prejudices, greens and young women stare, spell bound, and what's happening in front of them. and they watched everything closely,

fully concentrated and engaged people started here 7 years ago. here in the boxing arena in li, our visit to this new generation is doing really well. this is pakistan's future. we all hope to step into the ring for pakistan in the future. what's unique, it's mostly girls who bandage their hands getting ready to find good preparation is important, since they're no longer friends once they enter the ring. as we meet only assumable in the boxing ring, she's tearing on her friend and is fully engaged. she herself is not fighting today, not her age group. i. the floss was, you know, are this ring is if you're going to hang and do, are going to, you know,

your readings like the, i was going the thing and i'm, once i'm reading the, for all the after the 3rd round, it's clear that her friend has one, the boxing sleek and the stands and the coach all cheer. the champion gives a friendly pan on the band. only is the star of the scene. we meet her the next day at her boxing club. at 18, she has won nearly every fund in her way. class so far in karachi and all over the country. she trains 5 days a week and gives it her own hard game and i'm not doing and i'm not, i can't do. there's an icon, the doing for boxing, so it's not good. but if you're saying that icon to anything, so you are do anything. yeah. preparing for this foreign match with her best friend, warming up before getting down to business. so i am an idiot ready to him to form

a fight and i'm so excited because i'm going to fight and that's why, you know, i like i, my feelings was angry. i redid for my opponent, for some neither of the 2 friends gives in the dance around each other, get each other, give their own to the fine boxing between girls and young women has long been found upon and conservative, most of them pakistan. but, you know, and her friends no longer want to fulfill the traditional summit and role i'm charged boxing. so people are also saying that you are a god. you are not doing this. go back to reduce because it's not your work. uh, as far as war again, but are saying that you want to go to are also involved and making the fords. and uh, like, uh, you know, uh after a matter do, you are also how is that? i so you are not doing for other things, but this is not a good thing. i think so. but things are changing. even for the men watching here,

there are more important things than tradition is going was he doing over the we should do much more for the girls and encouraged them. we have a lot of drug problems here. we have to get the use out of it. and motivate them to do sports sports. so you're gonna play cat aaliyah shows us her neighborhood. she confidently states that we don't need to be afraid if she is there. everyone knows her about it is dangerous. here you are down here. so gang wireless and like a get him for anybody. but that's why people are also saying that this is danger. yeah, and i'm not coming here and you, but i also gave him for my, uh, my 1st turn to and my family works. and so that's what people are also saying that i would not come here. but poverty is the biggest problem. packet spans economy is on the verge of collapse. aaliyah takes us to her home. she says that her family doesn't have enough to eat every day. we meet her father, we climb

a ladder up to the roof as there was no room for all of us in the small apartment. he says he was happy to offer his daughter a different life and that the blows to her face would often lead to swelling. that she is getting rid of. sometimes i have work sometimes i don't remember now was one of the best for my children and i wanted all of you to learn english properly. i sent her to a language school for a few months, but now i don't have the money anymore and i have to give it on 6 year olds a month for her education. that's too much. she's now taking her faith into her own hands and wants to become a professional boxer. 6 she accepts all all the hurdles, and in john la, she will make it every 3 minutes. she has only a train, the

around 1800000 people worldwide lack adequate housing. the issue affects even wealthy countries. the number of homeless people in the us recently hit 650000 los angeles. rock bottom, you're on skid row, the cities worse neighborhood, and one of america's most dangerous. even so we can film here because we are joined by the general and are able to get some rare insights. he's been living on the streets here for almost 20 years. he's 61 now and skid row is this life. his young son lives far away with his mother, the 6th. they see each other every 2 months. the general lives here in

this tax. this is only hands. believe it or not is my thing to. so is like a mcculler the master ball master boot. that was like the gyptian of those to build the small pyramids where they can fit in and they would thing thing well believe it or not, i get it. busy done here is a way for me to get away from the world. you know, stand means that he will cru, we're on general duncan, with his nickname in prison furnace came drug addiction. then a life of crime, a bank robbery, logging, residents of people to be served 11 years, a time spent reading about prisoner's rights. he wrote prison complaints and became inactive. it one of the parks that was of the council river, one of the now he works for an aide organization. and during so it was $1500.00 a month. it was the result of 1000 for his wife and child 500 for himself residents . he believes that politicians want to keep get road this way on the road to get

rid of the homeless. here were straight to jail because the city took everything up because they want us to poverty and homelessness has always been criminalized in the city. like a homeless people has always been looking at and looked at a 3rd class citizens, the generative society. right. and with that said, investments have never been put in to homelessness and stuff. right. that they've invested, quoted for investments has been put in, but not in house, they vote for police. and so the majority of the money, the reason why i come, you see all is because the majority of the money goes to police and the homeless as opposed to housing. the home is the entire neighborhood. it's in the us or segregated and consistently neglected, especially black neighbors. it was called red lining, and its consequences are still felt here. she are already and hopelessness. the feet wide helps the homeless with his organization l

a can general dog on, also works for it. pete life wants to dispel, submit about homelessness. if you create a whole policy routed in people or houses because they want to be because of their substance abuse because of mental illness and the government has no right, right. like the government is not responsible. but when you start talking about housing affordability, housing availability, really start talking about structure. permanent housing is the key. this city of los angeles has also recognized this, but there's not enough affordable housing. a one bedroom apartment in the lake cost an average of $2000.00. maria esparza was lucky. after 2 years and a homeless shelter, she found her way into a city program. and now has her own apartment, is not done yet. it's

a day of new beginning for me. i mean, i love my place, it's comfortable. i love my big, huge package. you know, and like i said, just the be able to sit here and just, you know, do you art work? right. listen to music, watch tv, and just do by yourself is very nice. you know, uh, i missed that. and in the municipal programs, there are social workers in every home to help residential get back on their feet. also for the long term is hanging over, but there's a shortage of hundreds of thousands of apartments. so because it has a lot of meaning to so the city is trying to build quickly, re purposing municipal buildings and hotels. and i'm trying to stop people from losing their homes and the 1st place what we want to do is stop the and flow into homelessness right here. now, lake county, for approximately like we're able to bring about 200 people inside every day in the

housing, and about 220 people become homeless on that day. so we're, we have to stop the info into homelessness. if we're able to solve that info, then we'll be able to solve how much that is, even with the $700000000.00 that california has made available. they struggle to cope with the problem. but only can active this seem like at the end of the tunnel. now it's just not the black and brown for people. now you have white folks in asia and folks and others who are struggling with this. a kind of, i am, have seen that with so many other new faces joining the ranks of the poor that we will be able to build the power necessary to actually have policy that values overprint the american dream may be unattainable. but there's always a little hope general dog on is trying to save some money so he can move from

a 10 to an r v the the. so the my wish a dream would be where everybody have a place. you know, like the rats and roaches. we all go somewhere to go, crawled into the cubby hole. it's evening and last angeles, and as many leave the glittering office buildings for their beautiful homes. right next door on skid row. some people prepare for another rough night. the grenada, with its tropical heat and lust greenery, is a caribbean dream. on the east of the island, norbert, julian's tranquil farm,

coconut sentiment, bananas, papayas, and frankly, the trees full of not meg to see not megs of different stages. no 4th of all, that is a very tame defeat. yeah. very tender. young. right. from that fits it goes, it could be that states. right. and then after this, these, it come to that stage. how about example here? like we actually pop separating the, the, the, the part from the not make site. so if i open it all righty. eventually if it open . right. and then it will fall apart. i know this is an adult, much will not make at 1st glance, his plantation looks like a garden of eden, but it's threatened by climate change, and the warmer is the water gets the more destructive are the hurricanes. a good

doesn't hurricanes occur in the caribbean every year of these, an average of 2.7 become devastating or catastrophic category 3 to find storms. norbert remembers one particular hurricane with horror in just a few hours. he lost everything. everything was set up, right? everything was ready to all the trees on the ground and only a few tree will find them still. so everything was flap, don't update. for us, not us though, you know, bankruptcy. we have both a month to pay us on the phone and the ring died. so try, which is it, is it is really, yeah, we those pi a vanilla or exotic flowers. almost everything trying same granados volcanic soil.

the caribbean drain still exist with a sense and unique flavors, sentiment, pepper cloves, and cannot make the the music clumps and specialty restaurants and the port of capital st. george's fill up and the evenings the tourism is in full swing until the next hurricane. most islanders rely only on hope, met the next to retain sparrows. we'll just close our eyes and get through it. send them and then we'll provide caribbean spice for as long as possible. the small caribbean islands might completely vulnerable in the middle of the ocean . if a hurricane approaches the alarm bells ring in the media real logical operation center

and granada airport as with monster, hurricane events which reached the dangerous category 5 will probably be it made landfall on september 7th, 2004 that a half an hour. i think we had some speed off 11175. our strong ranada was set back decades. it's hard to imagine what will happen and the next hurricane hits the island you could be working for 50 is the build up. every thing i didn't want the, the one that's, that is all you had to gone. i mean, we saw that in the i 5, most of the victories went on. a lot of people live off that we

meet norbert julian's family at dinner. they're all deeply religious. they say that god confronts people with small trials and big ones, such as past and future climate catastrophes. hurricane ivan pulled the ground out from under his feet. since then, his harvest has not been enough to live on norbert julian's main job. driving a bus, not meg is no, just the hobby, the could oceans generate power. the technology to hong this ocean energy has existed for more than a century. it's known as ocean some energy conversion, whole tech. why has it yet to be embraced?

when you look at the surface of the ocean, the water here can be quite more because it's easy to find the sun and tropical waters that can be around 26 degrees celsius. at a 1000 meters deep, the temperature reaches roughly 4 degrees celsius. and this difference in temperature is what ocean thermal energy conversion utilizes. it's quite simple. you need a heat exchanger, the warm surface water heater of fluids that has a low boiling point. that fluid evaporates creating a theme. and that's theme runs a turbine, generating electricity similar to our regular steam engine. then the spring gets cooled by the deep sea water back into liquid. and the cycle repeats. this technology was late in 1881 by french physicist junk awesome dolphins on his student. josh quote then actually built the 1st book on successful tech plan in 1930 later interest in tech p to an oil prices exploded during the coil crisis and

1980 us president jimmy carter signed a loan to ensure the production of 10000 megawatts of electricity from opec in the next 2 decades. currently, there are 2 unsure of research plants, one on the island of coma in japan, with 100 kilowatts and the other one. and one are you with 100? 5 kilowatts. french developers were sent to launch a 16 megawatt plant in martinique and 2020. but the project has reportedly been shown due to technical difficulties. there were other research projects as well, but non lasted very long. so even though it's not a new idea, this technology is still very much in its infancy. most of the pilot plans were set up on shore to make a tech commercially viable. at, at a large scale, you need to go off sharp. this is him on kugler from the kite ocean engineering, which has been developing low tech parts in hawaii since 1979. you know,

the 510 amount of pipes, what do you need for your, your cold water and even for your return to your discharge pipeline, as well as the amount of trenching in shore line crossing that for commercial scale plants would just be infeasible. stem costs for him to as well going off shore makes it possible to install multiple tech platforms next to each other. similar to offshore wind parts. but currently costs are still more than double the price of other renewables. the tricky construction of the deep sea water pipes are turned off for major investors. last, before we get into that, let's look at whether it's technology companies use the major limits. in fact, the is that we need a big temperature difference between the surface and the deep sea water. warm surface water is available all year round in the tropical equitorial cell. so, oh, tech would help bring more energy to tropical islands. many of

them still rely on peaceful generators. studies even suggest that if you disregard practical and financial hurdles couldn't power the entire world, hypothetically. today, estimates for a $100.00 megawatt. oh, tech plant range from $780000000.00 to $1500000000.00. and there is another big, unknown cold water pipe and the pipes, the cold water pipe. these days hard plastic pipes up to 3 meters in diameter or no problem. but for 100 megawatt plant, you didn't pipes almost 4 times that size. they haven't even been developed yet. it is complex because the pipe needs to be stable. i'm flexible at the same time to not break apart when it gets hit by waves or currents. development is tricky. and india no tech plant never went online. because the deep sea water pipe failed. and

even if an old tech plant were to work, it could be destroyed by a storm. that's what happened to one of the 1st pilot plants in 1930. this uncertainty has driven away companies with more than $40000000000.00 us dollars in revenue, lockheed martin was sent to build the biggest tech plant to date and china, but dropped the project due to its cost. but it's possible that costs could be caught. for example, in the heat exchangers to give you a bit of perspective, the heat exchangers on a commercial scale attack plan are about a 3rd of the entire project cost. so the, the reason that these are so expensive for commercial attack is the up to you taking in deep sea water is very corrosive. we've developed what we call the thin foil heat exchanger. and as the name implies, we're using bin foils or, and the purpose of that is basically we're trying to reduce the amount of material and also the size. another big question mark is the actual effect on the

environment because you're moving insane amounts of water. we're talking about $4300000000.00 leaders of warm water and $2200000000.00 leaders of cold water per day for a small plant. there are a lot of question marks about our tech, the economics, the environmental side effects, the cold water pipe and today's ponds. i just way too tiny to figure anything of that out. and in the last 10 years, not much. this happens without serious investment, won't be taking off any time soon. would you like more insights and solutions from around the world? if you want to meet the people fighting climate change, visit us on facebook. if you want the story behind the headlines, follow us on instagram. and if you want green lights, tax checkouts optic till the
