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... show more

The Department of the Environment didn’t answer the question so I will. And I quote: “Bisphenol A is a highly toxic synthetic organic compound used in the epoxy resins of turbine blades. Epoxy resins contain 30-40 per cent bisphenol A and turbine blades are the largest global consumer of epoxy resins. The annual global production of bisphenol A is about 2 billion kilograms and is increasing because the spearing of the environment with wind turbines is today’s fad. Bisphenol A is an endocrine disrupter that has been linked to about 80 diseases including cancers and reproductive disorders. It is lethal for young children. In 2012, the World Health Organisation warned about the potentially carcinogenic properties of endocrine disrupters and concluded that they pose a global threat to public health. The European Food Safety Authority has massively reduced by 1,000 times the dietary intake of bisphenol A to one hundred millionth of a gram per kilogram of body weight per day. All this is public record information which the wind industry must know. The leading edges of turbine blades shed fine dust and blade edges only have a 5-year guarantee. Each blade sheds a minimum of 0.2 to 2.5 grams of bisphenol A in dust per year. This dust is spread wide and far by wind. If one gram of bisphenol A gets into dam waters, 10 million litres of water are rendered unusable. Over the life of a turbine, this equates to pollution of half a trillion litres of water per turbine. This is real pollution, not the alleged pollution of carbon dioxide, the gas of life. This dust from eroding blades has covered large areas of our planet and bisphenol A is leaching into soils and waterways. This is a toxic time-bomb.” Quote from: #auspol

"Unless I'm Absolutely Starving, I'm Not Eating Canned Soup Ever Again." Dr Andrew Huberman One serving of canned soup everyday for 5 days caused 1,000% increase of toxic BPA in urine. "Unless You Have A Powerful Reason To Consume Canned Soup---Don't Consume Canned Soup." More than 1,000% increase from only one serving for only 5 days is alarming knowing the harms that BPA does to the body. BPA is Bisphenol A, a known endocrine disruptor that mimics estrogen in ways that can activate or block estrogenic pathways. Every canned food HAS to have a lining to provide a barrier between the metal can & the food contained within. Make sure the lining used in your canned goods, if you purchase food in cans, is labeled BPA Free. This applies to every canned good including canned drinks, every can has a lining. BPA is classified as a hazardous chemical & is banned for use in food products in Europe. The US FDA still states BPA is safe & allows its use in food. BPA is used to line cans to lock in fresh flavor, but acidic ingredients like tomatoes, onions, & citrus, break down the BPA & get released into the food. Look for "BPA free" labeled cans when buying ANY canned goods. Look also for food products in Tetra Packs or processed in glass jars to avoid BPA. BPA Bisphenol A Has Numerous Harmful Effects: Endocrine disruption: BPA can mimic or block hormones, which can disrupt the body's normal functioning. This can affect the reproductive system, mammary glands, metabolism & cognitive function. Developmental and health problems: BPA can cause developmental & health problems in children, including learning & behavior conditions, early puberty in girls, diabetes, obesity & heart disease. Cancer: BPA is a factor for the development of various cancers, including breast, prostate, ovarian, cervical, & lung. Neurodevelopmental diseases: BPA has been linked to an increased of neurodevelopmental diseases, such as autism spectrum disorder (ASD). Respiratory issues: BPA can cause respiratory irritation & may affect normal respiratory function. Eye damage: BPA causes serious eye damage. Allergic skin reactions: BPA causes allergic skin reactions. BPA can be released into the environment at any stage of a product's life cycle, from production to consumption to disposal. You can reduce your exposure to BPA by using BPA-free products, avoiding heat & choosing fresh whole foods. 👇Randomized BPA Canned Soup Trial👇 👇Bisphenol A Harmful Effects👇 Speaker: Andrew D.

Major wind turbine manufacturers have been hit by an asbestos scandal. At Australia's $4 billion Golden Plains wind farm, testing on turbines has come back positive. Units are now quarantined and the manufacturer is launching global checks across its supply chain. This follows the asbestos found at a number of Chinese turbine manufacturers. Serious environmental concerns are now mounting. Wind blades can't be recycled, not economically or at scale. So tens of thousands of tons of blades are dumped every year, buried in pits with endless more coming as first-generation turbines hit their end of life, which is typically just 15 years. An industry sold as clean is leaving mountains of toxic waste that can't be recycled.

By 2050, the world is forecast to face 43 million tons of decommissioned wind turbine blades. These blades are built from high-strength composites made to survive years of weathering. Still, every single turbine standing today will age out before 2050. Most are difficult to recycle, so most are likely to be buried. But Europe now has a landfill ban for blades coming into force. Nations like Germany, Finland and the Netherlands are already blocking landfills. But they still have blades to dispose of. So the waste is pushed elsewhere. Blades are exported to countries where burial is still allowed, such as the UK. Net zero creates a mountain of composite waste. And then has the audacity to call it green.

Receipts are lined with BPA. One of the simplest ways to lower your exposure to this endocrine-disrupting chemical is to avoid handling them. It might feel trivial, but repeated exposure adds up. Cashiers and others who handle receipts daily have much higher BPA levels in their urine—evidence that BPA is absorbed through the skin while working. Crucially, nitrile gloves (not latex) block BPA absorption. If you’re handling receipts regularly, they’re a must. Hand creams and sanitizers can increase BPA absorption up to 100-fold. The practical takeaway here is apparent: If it’s not your job, skip the paper receipt and choose electronic instead. Small, consistent habits like this reduce your total chemical burden more than you might think.

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.

Consuming one serving of canned soup daily for just five days caused a staggering 1000% increase in urinary BPA levels—jumping from 1.1 µg/L to 20.8 µg/L. That’s one of the highest concentrations seen outside of industrial settings. Another study found that drinking from a BPA-lined can increase blood pressure 16 times compared to drinking a beverage from a glass. Other evidence suggests that urinary BPA levels found in these studies are also linked to disruptions in hormones. This isn’t just about canned soup—the same principle likely applies to other canned products, including soda, sparkling water, and other canned foods. It’s important to recognize that many aluminum cans are lined with plastics containing chemicals like BPA. The key takeaway here is awareness, and by reducing how often we consume food and beverages from these containers - we can limit exposure to BPA and potentially reduce risks associated with it over the long term.

#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.

Why does the turbine stop responding to stronger flow in the high-speed case when your natural instinct would expect it to keep speeding up? At that point, the blades are mostly interacting with the disturbed wake they created themselves. So, torque from different regions start cancelling and flipping in sign. The system hits a saturated balance. More inflow doesn't mean more net rotation, just more turbulence around the equilibrium. If you don't believe me take it up with: Wind Energy Explained (Manwell, McGowan & Rogers, 2010) or Aerodynamics of Wind Turbines (Hansen, 2008).

A modern wind turbine looks deceptively simple from the outside. The largest onshore turbines now use blades stretching beyond 80 metres, sweeping more than 20,000 m² of air. Yet the entire structure rotates at only around 10-20 RPM. Actually, inside the nacelle is a precision gearbox that transforms this slow, high-torque rotation into the 1,000-1,800 RPM required by the generator. This gearbox is one of the most demanding mechanical systems in renewable energy. It continuously transmits megawatts of power, while surviving changing wind loads, vibration and billions of fatigue cycles over a 20-25 year lifespan. Inside are planetary gear stages, precision-ground alloy steel gears, advanced bearings, lubrication systems and cooling circuits. Some of the largest geared turbines contain close to 1000+ liters of specialised synthetic oil to manage lubrication and heat during continuous operation. A single large onshore turbine can cost around $4-5 million, with complete projects costing significantly more after foundations, roads, electrical systems and installation. The goal is for the machine to recover its capital cost within roughly 5-10 years, then continue producing electricity for decades. This is why reliability is the biggest challenge. Gearboxes, bearings, generators and electrical systems remain critical failure points, pushing engineers toward better materials, sensors and predictive maintenance. The scale of this industry is enormous. China has become the world’s largest wind turbine manufacturing and exporting hub, with several Chinese companies among the largest turbine suppliers globally. Building a wind turbine is not just about capturing wind in an efficient manner, It is about creating a machine that can convert wind energy into electricity for millions of hours with minimal human intervention and sustain millions of load cycles.

Microplastics have been found in 100% of sperm samples tested. Studies show microplastics are linked to abnormal sperm shape and impaired motility, which means sperm can’t move as efficiently—bad news for fertility. 31% of the microplastics found in sperm come from polystyrene, a plastic commonly used in food packaging. Even worse, polyvinyl chloride (PVC)—used in water pipes—breaks down and leaches microplastics into tap water, a major source of exposure. Microplastics often contain BPA, a known endocrine disruptor that mimics estrogen. Research shows that men with higher BPA levels have significantly lower testosterone and reduced sperm quality. Reducing exposure is key: avoid heating plastics, use stainless steel or glass for drinking, and filter tap water with systems like reverse osmosis that remove microplastics. The goal is not panic—but informed action. To learn more about how microplastics impact reproductive health, the brain, the cardiovascular system, and hormones, check out episode 95 of the FoundMyFitness Podcast. Show notes:
