Spanish company Vortex Bladeless is developing a new way to generate wind energy without blades or a spinning rotor. Its cylindrical mast oscillates in the wind, and an electromagnetic generator converts this motion into electricity. With low maintenance and no rotating blades, the technology could be useful in urban... show more

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? 🤨

#zhanglinghe at press conference of documentary "Exploring the Future: The Answer is Earth" in Beijing🌱 Q: have you heard of Betz's Law? zlh🚀: it refers to the limit of how much wind energy can be converted into electricity. there is something called the Betz limit, which means that when a wind turbine converts wind energy into electrical energy, there is a maximum efficiency. about 59% or more precisely around 59.3%. this is a physical limit. to actually reach this limit, the conditions must be very ideal. for example, factors like the static pressure before and after the rotor, and the number of blades, all need to be in an optimal state. in real life, wind turbines don't reach that ideal. an efficiency of about 70%–80% (of the theoretical limit) is already considered very good. and in our country, the wind farms I've visited are basically among the best in the world, their conversion efficiency is extremely high.

How big is the world's first 20MW offshore wind turbine? On Feb 5, the world's first 20MW offshore wind turbine successfully completed commissioning and was connected to the grid in the waters off southern Fujian. Standing 174 meters tall with 147-meter blades, one full sweep of its rotor covers nearly 10 football fields. With just a single rotation, it can generate 50 kWh of electricity — enough to power one person for about 17 days. Follow our reporter's lens as he steps into the installation site.

Testing in Norway has found bisphenol A (BPA) in discarded wind turbine blades. BPA is an industrial chemical and recognized endocrine disruptor that can interfere with the body's hormone system. Authorities now want independent testing of soil, vegetation, and water around wind farms. Turbine blades spend decades exposed to rain, hail, ice, UV, and mechanical stress. They erode and crack, with old blades cut up and buried. We now await the test results to see exactly how much BPA escapes into the environment.

Wind power is sold as clean, but the turbines need extensive raw materials. Taking just the blades, a single set of three blades uses as many as 40 mature balsa trees. Balsa wood is light, strong and flexible, which makes it useful inside giant turbine blades that need to bend with the wind. Demand has surged and legal supply cannot keep up, so wild balsa is cut from protected Amazon rainforest where it should not be touched. It is then mixed into the legal supply and passed off as plantation wood. By the time it reaches manufacturers, illegal rainforest timber looks clean on paper. More than 500,000 balsa trees are illegally logged each year to feed wind turbine demand. Protected forest cut down, indigenous land raided, biodiversity destroyed - sold to the West as "green" energy.

Came across this awesome innovation to harness the power of the wind through tulip shaped wind turbines ! Flower Turbines, based in the US and the Netherlands is installing small flower shaped windmills which pose no danger to birds and other wildlife, particularly in urban settings. The company claims that they create very low noise which is undetectable to humans. This “eco-art” turbine is supposedly cost effective & easy to install making wind energy available for everybody. We must look at these options at #TNClimateMission

THIS VORTEX TURBINE COULD BE A GAME-CHANGER FOR ENERGY. 🚨A Belgian company (Turbulent) has created a hydraulic turbine that uses the natural vortex of water to generate electricity 24/7. 💥It installs in rivers, canals, or existing waterways. Advantages: • Very low environmental impact • Only one moving part → almost no maintenance • Installation in about a week • Works as long as there is flowing water • Can power homes or small communities It’s simple, clean, and it actually works. So why isn’t this kind of solution being massively deployed everywhere there is flowing water?

Back in the early 1900s, before electricity was common everywhere, a Swiss company called E. Paillard & Co. engineered a clever solution-a fully mechanical wind-up fan. Instead of wires or batteries, it used a tightly coiled spring motor, just like a clock. Once wound, the stored energy slowly released through gears, spinning the blades and producing a gentle breeze for up to 30 minutes. These fans were specially designed for tropical regions and remote areas where electricity simply didn't exist. Lightweight, portable, and surprisingly efficient, they offered comfort in hot climates without any power consumption. It was a perfect example of early innovation-simple physics turned into practical everyday technology. Even today, many of these fans still work after more than a century, showing how durable and well-crafted they were. In a world now chasing sustainable solutions, this old invention feels ahead of its time-a reminder that sometimes the smartest tech doesn't need electricity at all.

A turbine blade at the Vineyard Wind Project off Nantucket shattered in July 2024. Thousands of fiberglass and foam fragments washed into the ocean and onto Nantucket's beaches. Every south-facing beach was temporarily closed to swimmers while cleanup crews collected the debris. Federal regulators halted power production and further turbine construction while the failure was investigated. The company, GE Vernova, traced the failure to a manufacturing defect at its factory. Specifically, insufficient bonding inside the blade. Inspectors found the same bonding defect in at least 66 of the 72 blades already installed, with the blades ultimately having to be removed. GE Vernova later agreed to pay Nantucket $10.5 million over the incident. That is a remarkable environmental fail for technology being sold as the "clean energy future."

When a helicopter hovers near the ground, its rotor blades push down massive amounts of air. This powerful downwash creates a violent wind vortex on the deck. If the ground crew leaves even one piece of plastic or canvas unsecured, it transforms the landing zone into a trap . The vacuum effect sucks the lightweight tarp straight up into the rotor disc and the danger is catastrophic. A rogue object wrapping around the rotor head can instantly disrupt airflow, destroying all lift. Worse, the sudden mechanical resistance can tear the transmission apart, stall the engine, or shred the tail rotor, sending the aircraft into an uncontrollable spin. In this clip, you can actually see the sheer strength of modern engineering. Instead of snapping like twigs, the blades act like giant machetes. Modern rotors are built from advanced composite layers wrapped in titanium leading edges. They are designed to withstand massive kinetic forces, allowing them to literally shred the fabric mid-air. Even though the helicopter managed to fly away, it’s not out of the woods. The extreme stress of a rotor strike can cause invisible, microscopic cracks inside the blades. This aircraft is headed straight to the hangar for a complete teardown inspection before it ever leaves the ground again.

“Work has been suspended at a major wind farm project south west of Warwick after storms snapped a wind turbine blade. McIntrye Wind Farm recently connected some of its turbines to the grid, those works are on hold as it investigates the incident.” “The 458MW Coopers Gap wind farm in south west Queensland, the newest and biggest wind project built to date in Australia – is to undergo major repairs after faults were found in its commissioning process. AGL, which operates the $850 million project and is a joint owner through the Powering Australia Renewables Fund, said in a statement that the blades of one of the 123 turbines will have to be replaced entirely, while GE Catcon is also going to replace “generators” – referring to the equipment in the nacelle at the top of the wind tower – in a further 50 turbines.” •••••••••••••••••••••••••••••••••• Not only are wind farms unreliable in terms of wind dependent generation. They break easily as we saw last week on the Darling Downs. If the blades on a wind farm can’t survive a summer storm on the Darling Downs they will be useless. This is just another example of wind farms being unreliable. A few years ago wind farm had to replace 50 out of 123 turbines just after it was commissioned. Australia cannot not afford to be pursuing Net Zero policies being pushed by the two major parties. We should focus on using our coal, uranium and gas resources instead of imported materials.

I just posted an industrial-sized electromagnetic perpetual motion generator video ... and immediately, every bot, skeptic, and shill across the internet rushed out to mock it. They can laugh all they want. Thousands of videos already exist showing handmade perpetual motion generators that run entirely on their own....no external electricity needed. These machines generate more power than they consume, delivering true net-positive energy. They wont run forever without any care, but the maintenance required is remarkably minimal. The benefits? Absolutely incredible. Clean, limitless energy is no longer science fiction. The energy revolution has begun and eventually, these machines will be mass produced. It's inevitable⚡

Absolutely wild footage, this is a real world engine failure in a MD500 (Think Magnum P.I. helicopter) over Kauai, Hawaii out on a tour flight. You’ll probably have to watch this a few times but the video starts out with the helicopter under power and then the engine sound goes silent. The beeping you hear is the engine-out audio beep to inform the pilot that engine power has been lost. This maneuver that pilot is doing is called a Autorotation and the way to think about helicopter flight, the engine is turning this big fan (rotor blades) on top of the body and sucking in air from the top and projecting it downward to overcome the force of gravity. When engine power is lost, you experience a reverse in airflow because now gravity takes over and the air flow is coming from the bottom of the main rotor disk. The only thing the pilot can really do is to make sure the rotors keep spinning by changing the pitch of the rotor blades through the use of the “collective” which is a lever next to the pilot’s left leg and it only moves up and down. The pilot has to manipulate the collective during an auto rotation to make sure the blades keep spinning. If the pilot pulls up too much on the collective, the rotor blades will bite too much of air causing a resistance and slow the rotors down. If the pilot doesn’t pull enough collective.. the blades will speed up and potentially cause a catastrophic failure. The other control the pilot has is called the cyclic. This cyclic sits between the pilots legs and and manipulates individual pitch of the rotor blades to tilt the rotor disk aka “big fan” and make the helicopter go forward, backwards, left, right. So essentially in this type of emergency, you have to manipulate the controls in a delicate balance because no matter what, gravity is taking you to the ground because the engine is no longer producing power. The pilot did an outstanding job here given the geography and limited amount of flat terrain to put the helicopter on the ground. Thankfully it sounds like no souls were lost and only one injury according to a news report (see the link below)👇 Of course there is a lot more to helicopter aerodynamics but I’m trying my best to put this in simpler to digest terms. Big thanks to Combat Learjet for sharing and definitely worth a follow!
