Any too well how tough spots were on the beach of karachi unpack. It stands for reading and see sure. Its a long weekend fun on the waterfront for pakistans middle class, the country is facing a crucial test. We can sense that here. So nobody believes that anything will change quickly and fundamentally after the election. If youre getting with them, i goes with the problems with these things. So if you are going right, i didnt 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 very few foreigners come to this district notorious for drugs in gain crime, we are immediately surround it. Everyone wants to tell us something. What we need here is like tricity water, gasoline. I mean, thats all we need here, but can we help our selves . But thats what we need somebody to pull it up and move 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 whats happening in front of them. They watched everything closely, fully concentrated and engaged. The people started here 7 years ago. Here in the boxing arena in li are you is new generation is doing really well. This is pakistans future. We all hope to step into the ring for pakistan in the future. Whats unique, its mostly girls who bandage their hands getting ready to fight. Good preparation is important, since theyre no longer friends once they enter the ring. As we meet only assumable in the boxing ring, shes tearing on her friend and is fully engaged. She herself, is not fighting today, not her age group. Now i, the floss was, you know, are this ring is if you are going to ring and do are going to, you know, your readings like the, i was going the thing and im, once im reading the after the 3rd round, its clear that her friend has one, the boxing sleek and the stands in the coach, all cheer. The champion gives a friendly pan on the back. 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, plants so far in karachi and all over the country. She trains 5 days a week and gives it her own hard game and im not doing and im not, i cant do. Theres an icon, the doing for boxing, so its not good, but if youre seeing the 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 im so excited because im going to fight in that way. You know what like i, my feelings was angry. I retired from a born in for some neither of the 2 friends gives in the dance around each other, get each other, give their own 2 minutes to find boxing between girls and young women has long been frowned upon and conservative, most of them pakistan. But you know, and her friends no longer want to fulfill the traditional summit enrolled and started boxing. So people are also saying that you are a god, you are not doing this. Go back to redeem because its not you are worth a h bars. Why again . But are saying that you want to go to are also involved and making the fords. And uh like, uh, you know, after a matter do, you are also how is that i so youre 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 with the general. We should do much more for the girls and encouraging 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 people to play. Cat aaliyah shows us our neighborhood. She confidently states that we dont need to be afraid if she is there. Everyone knows her about it is dangerous. Here. You are so im here, so gang wireless and like a getting him for anybody. But thats why people are also saying that this is done through. Yeah. And im not coming here and do, but i also getting him for my uh, my 1st turn to and my family works. And so thats what people are also saying that i have 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 doesnt 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. As the farmers that shes getting rid of, sometimes i have words. Sometimes i dont remember now is one of the best for my children. I wanted all year to learn english properly. I sent her to a Language School for a few months, but now i dont have the money anymore. We had to give it all 6 year olds a month for her education is too much. Shes now taking her feet into her own hands and wants to become a professional boxer. 6 she accepts all the hurdles and enjoy law. She will make it every free minute. She has only a 3 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, the los angeles rock bottom. Youre on skid row, the cities worse neighborhood, and one of americas most dangerous. Even so we can film here because we are joined by the general and are able to get some rare insights. Hes been living on the streets here for almost 20 years. Hes 61 now. And skid row is this life. Because young son lives far away with his mother, they see each other every 2 months. The general lives here and this time. This is only hands. Believe it or not is my thing to. So is like a mcculler mass the the master boot. That was like the gypsy and theres to build the small pyramids where they can sit 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. Were on general duncan with his nickname and present. First came drug addiction. Then a life of crime, a bank robbery, logging, residents of people to be served 11 years to time spent reading about prisoners, right . He wrote present complaints and became inactive at one of the parks that was of the account. So remember one, now he works for an aide organization and or, and so it was 1500. 00 a month. The result of 1000 for his wife and child 500 for himself residence. You know, he believes that politicians want to keep get road this way on the road to get rid of the homeless. Here are straight to jail because the city took everything up because they want us to poverty and homelessness has always been criminalized in a city. Like a Homeless People has always been looking at a looked at 3rd class citizens, the generative society. Right. And with that said, investments have never been put in to homelessness and stuff. Right. That theyve invested or go to investments has been put in, but not in housing, but for police. And so the majority of the money, the reason why i come, you say all is because the majority of the money goes to partners and the homeless as opposed of houses in the home. Its the entire neighborhood. Its in the us or segregated and consistently neglected, especially black neighborhoods. It was called red lining, and its consequences are still felt here. The sheer already and hopelessness white helps the homeless with his organization l a can general dog on also works for it. Pete light wants to dispel, submit about homelessness or 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, then the government has no right. Right. Like the government is not responsible. Well, when you Start Talking about housing affordability, housing availability barely Start Talking about structure. Permanent housing is the key. The city of los angeles has also recognized this, but theres not enough affordable housing, a one bedroom apartment, a late 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. Not been yet. Its a day of new beginning for me. I mean, i love my place, its comfortable. I love my big huge you know, and like i said, just to be able to sit here and just, you know, do you art work, right. Listen to music, watch tv. And just be by yourself. This is very nice. You know, uh, i missed that. And in the municipal program, there are social workers in every home to help residents get back on their feet on. Is it also for the long term is hanging over, but theres a shortage of hundreds of thousands of apartments. So because it has a lot of meaning to it. So the city is trying to build quickly, re purposing municipal buildings and hotels. And im trying to stop people from losing their homes and the 1st place what we want to do is stop the inflow into homelessness. Right here, now lake county, for approximately like were able to bring about 200 people inside every day in the housing, and about 220 people become homeless on that day. So were, we have to stop the info into homelessness. If were able to solve that inflow, then well 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 and we can active is c like at the end of the tunnel now its just not the black and brown for people now. 2 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 theres 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 direction or roaches. We all go somewhere to go, crawled into the cubby hole. Its evening and last angeles, and as many leaves 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 lush greenery, is a caribbean dream. On the east of the island, norbert julians tranquil farm, coconut sentiment, bananas, papayas, and frankly the trees full of not meg. To see nothing makes a different state is no fault of all that is the very time to meet 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 wait, actually pop separating the the, the pod 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 its threatened by Climate Change and the warmer the water gets the more destructive are the hurricanes. A good dozen hurricanes occur in the caribbean every year of these, an average of 2. 00 become devastating for catastrophic category 3 define storms. Norbert remembers one particular hurricane with horror in just a few hours. He lost everything. Everything was set up, right . Everything was ready, the audio trees on the go. So only a few, 3 or 5 minutes to so everything was flap, dont update for us, not us. So you know, bankruptcy. We have both a month to pay us on the phone and the ring died. So what time would you say is there a year with us . Papaya vanilla so exotic flowers. Almost everythings right, same granados volcanic soil. The, the caribbean trains still exist with its sense and unique flavors, sentiment, pepper cloves, and cannot make the, the music plums and Specialty Restaurants and the port of capital st. Georges. Fill up and the evenings the tourism is in full swing until the next hurricane. Most islanders rely only on hope, but the next to retain sparrows will just close our eyes and get through it. Send them and then not mike will 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, ro, logical Operation Center and granada airport as with monster, Hurricane Events which reached the dangerous category 5, the property, it made landfall on september 7th, 2004. And thatll happen though, i think we had some speed off 11 on 175, our strong ranada was set back decades. Its hard to imagine what will happen and the next hurricane hits the island. You could be working for 50 years to build up everything. I didnt want the the one thats that is all the hardwood gone. I mean we saw that in the i 5 most of the victories when those a lot of people live off of that. We meet norbert Julian Stanley at dinner. Theyre 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 julians main job, driving a bus. Nutmeg is now just a hobby. The could oceans generate power. The technology to hong this ocean energy has existed for more than a century. Its known as ocean some more 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 its 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. Its quite simple. You need a heat exchanger, the warm surface water heat of fluids that has a low boiling point, that fluid evaporates creating a theme. And thats 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. Ill send dolphins on his student, josh quote, then actually built the 1st spot on successful opec plan. In 1930 later interest in opec. Pete, when 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 coolant and 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 its 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 that, a large scale, you need to go off sharp. This is him on kugler from the college ocean engineering, which has been developing low tech parts in hawaii since 1979. You know, the size and amount of pipes, what do you need for your, your cold water and even for your return your discharge pipeline, as well as the amount of trenching in shore line crossing to add 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, lets look at whether its 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 zone. So, oh, tech would help bring more of an oval energy to tropical islands. Many of them still rely on peaceful generators. Studies even suggest that if you disregard practical and financial hurdles couldnt power the entire world, hypothetically. Today, estimates for a 100. 00 megawatt. Oh, tech plant range from 780000000. 00 to 1500000000. 00. And theres another big, unknown cold water pipe in 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 think pipes almost 4 times that size, they havent even been developed yet. It is complex because the pipe needs to be stable. Im flexible at the same time to not break apart when it gets hit by waves or Current Development is tricky. In 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. Thats what happened to one of the 1st pilot plants in 1930. This uncertainty has driven away companies with more than 40000000000. 00 us dollars and revenue, Lockheed Martin was sent to build the biggest tech plant to date and china, but dropped the project due to its cost. But its 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, a tech plant are about a 3rd of the entire project cost. So the, the reason that these are so expensive for commercial attack is the canyon deep sea water. Its very corrosive. Weve developed what we call the tin foil heat exchanger. And as the name implies, were using bin files. And the purpose of that is basically were trying to reduce the amount of material and also the size. Another big question mark is the actual effect on the environment because youre moving insane amounts of water. Were talking about 4300000000. 00 leaders of the warm water and 2200000000. 00 leaders of cold water per day for a small plant. There are a lot of question marks about attack the economics, the environmental side effects, the cold water pipe, and todays ponds. Ill just wait to tiny to figure anything of that out. And in the last 10 years, not much this
