Korea builds worlds first floating solar power plant that tracks sunlight
The sun is our most important source of renewable energy. but unfortunately we havent gotten round to finding a cheap and reliable way of converting into enough electricity for all of us. However. in a small step toward achieving this goal. Korea has just finished construction of a floating solar power plant. the first of its kind in the world. Won Jihyun reports. This massive solar power plant floats on a reservoir in Gyeonggido Province. And round and round it goes. following the suns movements throughout the day. This gigantic facility. that measures around 75hundred square meters was built last.
Year by a Korean energy firm called Solkiss. The floating plant is made of roughly 16hundred solar voltaic modules installed on a floating deck. that rotates on water. Using a tracking system the deck moves in the direction of the sun to maximize efficiency. Since the floating modules can collect sunlight thats reflected off water developers say this type of plant can generate more power than groundbased systems. The groundmounted rotating system can collect solar energy for an average of 3.6 hours a day. Based on our observation from January until June we found out that the.
How Bicycle Powered Cell Phones Are Saving Uganda
Worldwide, there are more than one billion people living off the electricity grid and, while, we often hear glamorized stories of millionaires choosing to live without artificial light, they are in the minority. Many don't have a choice. Energy poverty is endemic with about 20 percent of the global population lacking reliable sources to power their electronics, businesses, and plain old light bulbs, which can be a huge problem, especially in our increasingly virtual world. This is why some of Africa's developing nations are looking to the future with solar energy in mind. People and organizations have come together to find solar solutions.
While traveling through subsaharan Africa, entrepreneur Mike Lin witnessed the many off grid families coping with dangerous kerosene lamps.We've been having so many accidents from using kerosene lamps. Children get burnt, said one Ugandan woman. And about 1.5 million people die from kerosene lamp related respiratory illnesses every year. Inspired to build a safe, reliable, energy source, Lin and his cofounder Brian Warshawsky started Fenix International, got people on board, and ReadySet was born a portable energy battery that can be fueled by the sun or pedaling on a stationary bicycle. Its introduction has transformed communities.
Before ReadySet, a Ugandan woman says, I had no hope of getting electricity. But now I just need the sunlight energy to charge my solar panel. It allows her and others to stay connected and has eliminated the need to travel and pay high fees to charge her phone, for example. And for children the majority of whom are unfortunately expected to work during the day light at night means they can do their homework and further their education. These extended periods of light have changed businesses as well, Now I.
Get a lot of customers because I have a bright light. I can even work for 5 hours at night says one shop owner. And hospitals and other facilities can use similar solar energy systems to improve their services. Solar technology is spreading throughout Africa. Partly because of this, Akon, the famous musician, launched a Solar Academy with aims to consolidate African expertise and teach people how to install and maintain solarpowered electricity. And, on a more global scale, the United Nations has decided to name 2015 the Year of Light.
Solar Panels for South Sudan
With modern technology we can turn the sun's light into energy. We are Energiya Global, and, we build utilityscale solar fields. In Africa there are 600 million people without access to electricity. Many people use diesel generators, which are both expensive and polluting. In South Sudan, We are leading a campaign to build a new solar installation on His House of Hope hospital, an orphanage and primary school in the Yei region. Currently, the hospital does not have enough electricity to operate the life saving equipment that serves the vulnerable population of Yei. Solar installations can bring clean and affordable energy to population.
Worlds first floating solar power plant in operation in Korea
Speaking of energy,. the worlds first solar plant constructed over water has started operations here in Korea. The local developers say. similar plants like this one. could one day make waves in the global energy market. Our Sohn Jungin takes us to the plant. This is the worlds first rotating, solar power plant on water. Unlike other conventional solar facilities that are fixed on land, this module is designed to move along with the movement of the sun during the day, which increases energyefficiency by 22 percent. The floating plant in Anseong, Gyeonggido Province consists of 16hundred panels that.
Can produce 2thousand kilowatts of energy per day,. which is enough to supply about 200 households. The concept of movable solar panels is not new, but other versions consume a great amount of energy to rotate. This one does not. Using water buoyancy, two motor engines are enough to operate an 8thousand square meter generator that follows the suns movement to maximize efficiency. The installation can withstand winds of 50 meters per second and can adjust its level depending on water level changes. Water fountains around the module are designed to lower the temperature of the water to prevent.
Elon Musk Tesla and SolarCity Will Accelerate the Development of an Energy Solution
The reason I put so much time and effort into creating Tesla was because, it's always said to me that the transportation won't go electric and should go electric, but we have an unpriced externality in the negative effects of gasoline and on the environment and also in the wars that we fight and national security and that kind of thing. Whenever you have an unpriced externality you can't quite rely on the market to do the right thing. So in order to have electric vehicles come sooner than they otherwise would.
Electric vehicles were always going to be the longterm transportation mechanism, but to make that day come sooner, you have to bridge the gap with innovation. That was the goal with Tesla is to try to serve as a catalyst to accelerate the day, the day of electric vehicles. And I think when all is said and done, I am hopeful that historians will look back on Tesla and say that Tesla advanced that by at least 10 years, which that would be a huge victory of mine. in my mind.
SolarCity, of course, is on the energy production side of things because it doesn't help if we have sustainable consumption of energy, but then that energy isn't produced in a sustainable way. I feel quite strongly that solar power will be the single largest source of electricity generation by midpoint of the century. In fact, just a simple extrapolation of the growth of solar power would for sure, that that's obviously going to be the case. And also when you consider that the earth is almost entirely solar powered today and that the fact that.
We're not a frozen ice ball at say 4 degrees kelvin and it's just due to the sun. And the whole ecosystem is powered by the sun. There's just an itty bitty amount of energy that we need to do complicated human things. It's a tiny amount of energy really compared to what the sun puts on the earth every day. And we just need to capture a little bit of that and turn it into electricity. So we have to try to accelerate that with innovation. And that's what SolarCity is about.
Yosef Abramowitz on Ask The Source
Yosef, There are tens on millions watching the show, what message do you have for our viewing audience This climate issue affects poor people around the world primarily, and we can beat it. We can beat it with the cooperation among countries, using Israel as a platform to solve global problems, like climate. We invite your viewers to join with Israel any which way. Through investments. Through charity. We're going to be launching very shortly a crowdfunding campaign for His House of Hope in South Sudan. South Sudan is also a poor country, faced with a lot of conflict. They have asked us to do solar power for one.
How to Install Solar Panels Mounting Rails on Roof for Solar Panels
All right, we're getting ready to mount our rails up here, and I've got some blocks of wood. Pressure treated lumber already mounted, from one of my last solar projects, so we'll reuse those when we can. This roof is over the laundry room, and it's facing almost directly south, which is perfect for a solar exposure. Not too difficult for that top end. Let's get some down at the bottom now. Drill a couple of holes here, so we've got a couple more blocks of wood, just to rise this up off the roof. Give a.
Fulbright on the Millennial Trains Project Lala, South Africa
Music I'm on a train. Giggles My name is Nhlalala, and I am from South Africa. We're on the Millenial Trains Project, which is a project to bring people together across the country and with Fulbright across the world. I am on a Fulbright scholarship to do my PHD, in Neuroscience, my focus is on obesity. I went to see a school nutrition program which is done by Liberty's Kitchen. And it's amazing. They try to teach kids, school kids, first they teach them, empower and they nourish. So they teach kids about.
Healthy living, healthy eating, they empower them through the programs they have, youth development, and then they feed the school kids. There are definitely parallels, especially when it comes to childhood obesity, in South Africa it's increasing. I am used to being in the lab. It's different looking at from a social side, cultural, and community. I learned a lot. Especially it was good going through these cities with the Americans, learning from them. I'm Nhlalala Mavundza, I am a Fulbright from South Africa and I am on the Millennial Train.
