🇨🇳 CHINA'S WIND TURBINES NOW FLOAT ABOVE THE CLOUDS China's new stratospheric airship is designed to cruise 12 miles above Earth and generate electricity using a built-in wind turbine. Up there, winds are 5 to 8 times stronger than on the ground, meaning this thing could produce serious, consistent...

Must watch explanation on clean energy by Greg Jackson on #BBCQT - also watch Tim Stanley squirm repeatedly when Jackson gives answers Greg Jackson, "We've crossed the rubicon.. Clean energy is now cheaper than fossil fuels" "Power from wind and solar is cheaper than power from fossil fuels" "Consumers don't see the benefits because our markets are run in the old traditional way" "We need market reform so when we build wind farms, people get cheaper energy" "It doesn't help that we are paying wind farms to turn off when it's windy, instead of giving people cheap power at those times" "59% of all of the renewable energy has been built in China" Fiona Bruce, "They're also building huge coal plants" Greg Jackson, "The majority will never be used, they'll be mothballed" "Why are they building green energy? It's not because they're nice people. Now they recognise clean energy is cheaper, and energy is the engine of growth for their industry, they're investing in it" "Six or seven years ago if you went to Chinese cities people wore face mask because of air pollution.. That's gone" Tim Stanley, "If you have a period where the wind dies and the sun doesn't shine, what happens, you have to rely on back up.. Rely on gas.. Import the power from overseas" Greg Jackson, "Allow me to help you with this answer.. As somebody who buys more power than anybody in the UK.. I can give you an authoritative answer on what to do" "An electric car holds enough power in its battery for a typical house in the best part of the week" "As more and more electric cars hit our roads, we have distributed storage of electricity, days on end, without wind" "It's not the whole solution but it's a big part of it.. And it helps us reduce our reliance on things like those fossil fuel backups" "It's always windy somewhere, it's always sunny somewhere.. As we connect our country to others.. When they're windy we get their power, when we're windy we sell ours to them" "By the way, we are one of the windiest places in the world.. This is a huge export opportunity for the UK"

China completes installation of world's largest single-unit floating offshore wind turbine The world's largest single-unit 16-megawatt floating offshore wind turbine "Three Gorges Pilot" was installed on Saturday in waters off Yangjiang, south China's Guangdong Province. The 16-megawatt floating offshore wind turbine consists of three parts, namely a 16 mw ultra-large capacity wind turbine, a semi-submersible floating platform, and a new mooring system. With a maximum tip height exceeding 270 meters, the wind turbine rotor has a diameter of 252 meters, with a swept area equivalent to seven standard football fields. Unlike traditional fixed-bottom turbines that are physically connected to the seabed, it is installed on a semi-submersible floating platform measuring 80.82 meters long, 91 meters wide, and with a displacement of 24,100 tons. The platform is secured through nine suction anchors, combined with domestically produced high-performance polyester fiber cables and anchor chains for seabed mooring and positioning. "To deal with the harsh sea conditions, our team has developed and applied a new mooring system, a dynamic monitoring system, an active ballast system, and 66 kV dynamic submarine cables for the first time in China," said Pan Hongguan, an offshore wind power engineer from Guangdong Branch of China Three Gorges Corporation (CTG). According to Pan, the new mooring system combines polyester cable and anchor chain, which is like adding a "spring" to the middle of the system, to deliver superior mechanical performance. The "Three Gorges Pilot" wind turbine previously completed its integrated assembly at Tieshan Port in Beihai of south China's Guangxi Zhuang Autonomous Region. It arrived at its target sea area located more than 70 kilometers off the coast of Yangjiang after a long-distance towed voyage across the Qiongzhou Strait which connects South China's island province of Hainan with Guangdong Province on the mainland. After being put into operation, the wind turbine is expected to generate approximately 44.65 million kilowatt-hours of clean energy annually, enough to meet the annual electricity demand of 24,000 households.

Elon Musk has been saying the same thing for years. Humanity is still underestimating solar energy. Not underestimating it slightly. Fundamentally misunderstanding what it is. Musk: “What would the Earth be without the sun? The Earth would be a frozen dark ice ball at roughly three degrees above absolute zero.” Three degrees above absolute zero. No light. No liquid water. No life. Not a worse version of Earth. A dead rock drifting through nothing. That is the default state of this planet without a single energy source. Everything else is commentary. The sun is not one option on a menu of power generation. It is the only reason biology exists here at all. Musk: “Because of the sun, we are at a quite a nice temperature, quite pleasant. Sort of roughly 300 degrees above absolute zero.” A 297-degree window between civilization and extinction. Every ecosystem, every economy, every human body operates inside that margin. The entire project of life fits between those numbers. And somehow the species looked at the source of all of it and decided it was a secondary energy option. Musk: “The sun powers, almost the entire ecosystem is solar-powered.” Every fossil fuel on Earth is stored solar energy. Oil is ancient sunlight captured by organisms, compressed by geology, buried for millions of years. Drilling for it is harvesting the sun’s output with a 300-million-year delay and a catastrophic loss in efficiency. The original source is still running. It will run for another five billion years. It delivers more energy to Earth’s surface in one hour than humanity consumes in an entire year. One hour versus one year. That is the ratio the world is ignoring. The argument against solar was never physics. It was cost, storage, and scale. Those are engineering problems. Engineering problems get solved. They always do. The compute demands of the next decade alone will require energy production at a scale fossil fuels physically cannot reach. The intelligence explosion does not run on oil. It runs on electricity. The cheapest and most abundant source of electricity is already overhead. It has been overhead for 4.6 billion years. We do not need to discover a new energy source. We need to stop ignoring the one that powers everything we have ever built. The star is right there. The only question left is how fast we build the infrastructure to capture it.
