This technology has me curious. It's called Wind Sail Propulsion. It's still in the 1.0 stages IMO. It's kind of interesting though and could potential save on fuel costs to get things across the ocean. It harnesses wind energy to assist or, in some cases, serve as the primary... means of propelling ships. Another technology is the Flettner rotor, which uses the Magnus effect—created by spinning vertical cylinders in a wind stream—to generate forward thrust. Unlike sails, the rotor is powered by its own motor, allowing it to generate propulsion even when wind direction is unfavorable. Do you see potential for this kind of technology? What kinds of potential problems could arise? 🤨show more

🇺🇸 ENERGY SEC. WRIGHT: WIND AND SOLAR CAN’T REPLACE RELIABLE ENERGY "The problem with wind is that the wind doesn't always blow. If the wind is blowing, you can say it's powered by wind power, then the wind stops or the wind gets weaker. Something has to fill that gap in always be there. So when you add wind and solar onto a grid, you don't remove the need for coal plants, for nuclear plants, for natural gas plants, that work all the time. So to maintain two grids instead of one grid is always more expensive." Source: Fox News

CNN: He claimed that China builds a lot of wind turbines and manufactures them for others, but refuses to use it itself, barely uses wind power. In fact, China is the world leader in the use of wind power. It is building additional wind power in China far faster than the pace at which the U.S. Is building in the United States itself. So the idea that China is just, you know, foisting this terrible source of energy on other countries while refusing to use it is a reversal of reality.

To get you in the mood for the Winter Olympics, here is some wonderful 1951 footage of the British ski team training in a wind tunnel. Despite having this technology available, sadly the best a British Skier could do in Oslo in 1952 was Hilary Laing's 24th place.

•042426• new interview of #zhanglinghe with Movie News for "The Answer is Earth" documentary 💬🌱 ZLH🚀: this is a small souvenir they gave me when I visited the wind turbine manufacturing plant. 👤: I know you really like these kinds of things. ZLH🚀: yes, this is the motor of the wind turbine, located at the highest point of the turbine shaft. these are the blades. they look small now, but in reality, when I went to the wind turbine manufacturing plant, it was about 80 meters long. really huge. and the proportions might not be accurate. when we stood below it, it was incredibly impressive. it works like this: the wind comes from this direction and drives the blades to rotate. then the motor converts that kinetic energy into electrical energy. there are cables below that can directly transmit the electricity to a substation, where it's stepped up or down in voltage, and then sent to places on land where the electricity is used. that's how a wind turbine works. 👤: it's a very meaningful souvenir. ZLH🚀: yes. 👤: where are you planning to put it? ZLH🚀: before I brought this with me, I usually keep it next to my computer.

$There is no energy transition. Oil, coal and gas still supply 87% of the world's energy - roughly the same share as 20 years ago. Despite trillions in subsidies, solar and wind barely register on the global chart, accounting for just 6.5% of the primary energy supply. Fossil fuel use keeps rising, particularly in China and India. The renewable revolution can still only power a small fraction of the planet, and only when the sun shines or the wind blows. This is the data the headlines leave out. The transition isn't happening. It's a slogan.$

🇮🇳ELON: INDIA HAS MORE ’PROMISE THAN ANY LARGE COUNTRY IN THE WORLD" Reporter: How do you see PM Modi's leadership in making technology inclusive? Elon: "He wants to do the right thing for India, he's open and supportive of new companies. There is a tremendous amount of potential for a sustainable energy future, including sustainable energy generation through solar and wind. The amount of land required to power all of India is only 1 or 2% of the land. Very doable. We're also looking forward to bringing Starlink to India, which will be very helpful to remote or rural villages without access to the internet." Source: DogeDesigner

Australia needs to take advantage of AI before it takes advantage of us. This is quite the show. The progress in AI technology as demonstrated by these robots is both impressive and scary. Impressive as to how far AI technology has come, and scary in the sense of the potential job losses AI will bring. Australia really needs to get up to speed when it comes to manufacturing and technology skills. The sooner we up skill our workforce to ensure we are not beholden to foreign controlled AI the better.

Marc Andreessen says AI is hyper democratizing. “Is the future of the world going to be one or a small number of companies, or for that matter, governments or super AIs that kind of own and control everything?” “Or is this a technology that's going to diffuse out and be in everybody's hands?” “This is the time in which AI is actually hyper democratizing. It has spread to more individuals, both in the country and around the world in the shortest period of time of any new technology I think in history.” “The best AIs in the world are in the consumer products.” “This technology is going to be in everybody's hands. And everybody is going to be able to use it to optimize the things that they do, have it be a thought partner, assistant for building companies.” Marc Andreessen 🇺🇸

Warriors of Calradia be ready to truly command the seas in War Sails! ⚓ It’s all about mastering the rhythm between your sails, wind, and oars. Unfurl your sails to chase the wind, furl them when precision matters most, and always keep an eye on the wind dial - green means go, red means resistance. 🌬️ Each rig changes the game: Square sails give explosive bursts, Lateen sails keep your pace across angles, and Hybrid rigs balance both. When the wind fades, your oars take over - row steady or go full power for speed, but remember, fewer hands left to fight! Get it right, and you won’t just sail - you’ll own the sea. 🌊 #mountandblade #bannerlord #warsails

Mendocino Engine. The Mendocino engine is an electric motor that can be powered by any type of light, be it sunlight, moonlight, or even artificial light. It features a magnetically levitated rotor, almost completely eliminating friction. Its primary application so far has been for technology demonstration purposes only; it is said to be incapable of generating power on a large scale and is kept in plain sight, hidden under the label of a toy. Movement generates energy, right? Free Energy.

We currently pay £1.5 billion a year to switch wind farms off when it's too windy. Rachel Fletcher from Octopus Energy has just told Parliament that could soar to £10 BILLION by 2030. Ed Miliband is writing cheques for wind farm developers before the grid can move their energy to where it's needed. This is a political choice and it is making electricity expensive.

Elon Musk: Here's what we need to have a fully sustainable energy economy. “There are three elements to a sustainable energy future. One is sustainable energy generation, which is primarily wind and solar. There's also hydro, geothermal. I'm actually pro-nuclear. I think nuclear is fine. But it's going to be primarily solar and wind as the primary generators of energy. The second part is you need batteries to store the solar and wind energy, because the sun doesn't shine all the time, the wind doesn't blow all the time. So it's a lot of stationary battery packs. And then you need electric transport. So electric cars, electric planes, boats. And ultimately we can have a fully sustainable energy economy. And it's those three things: solar/wind, stationary battery pack, electric vehicles. So then what are the limiting factors on progress? The limiting factor really will be battery cell production. So that's going to really be the fundamental rate driver.” Source: TED, April 14, 2022.

Sequoia's Ravi Gupta and Pat Grady on potential layoffs and why the AI doomers are wrong: "Technology is neither good nor bad, it's what we do with it. The same technology that powers a nuclear bomb can power a nuclear power plant." "A lot of what people are doing when they go and talk about the technology is they talk about all the things that might happen. I would rather us talk about the fact that it's going to get more and more powerful, and it's more and more incumbent on all of us to make sure we use it for something great." "If I could give my kids one thing, it wouldn't be kindness. It wouldn't be curiosity. It would be agency. The technology is going to be what all of us make of it."

Solar and wind are sold as cheaper than coal, gas or nuclear using a number called LCOE (Levelized Cost of Energy). But LCOE is a junk metric. It pretends that one-megawatt-hour of intermittent power is the same as one-megawatt-hour of reliable power. It isn't. When the sun doesn't shine or the wind doesn't blow, you still need electricity. So backup plants (coal, gas or nuclear) must run in the background, ready to fire instantly. LCOE fails to count that cost. It also ignores the miles of transmission lines for remote wind farms, the giant storage systems to cover lulls, the stabilizers to keep frequency steady, and the massive overbuild needed just to survive bad weather weeks.These hidden costs explode as wind and solar take over more of the grid. On paper, LCOE makes these renewables look cheap. In reality, they drive up costs system-wide. That's why nations with the most wind and solar have the highest electricity prices. LCOE isn't just misleading, it's a lie.
