We have an exciting post today focusing on one of the pieces of equipment at our United Downs site – the turbine! Read on to find out the turbine’s role in our geothermal power plant! Our Project Manager, Charlotte Wilkins, explains more about the turbine below: “The turbine, seen to the left of the below picture wrapped in silver insulation, is the central component in the ORC system. When the superheated motive fluid is released into the evaporator, it immediately changes state from a liquid to a gas, and this creates pressure in the evaporator. The pressure escapes down a pipe to the turbine, and by acting on the turbine blades, forces it to spin. The spinning turbine is used to turn the generator, which by turning a conductor in a magnetic field, induces an alternating electric current. Thus the turbine takes potential energy from pressure converting it to angular kinetic energy at the turbine and then electrical energy at the generator. The generator and turbine have been carefully aligned using lasers and then locked in position to ensure minimal noise and vibration. The turbine itself is continuously sprayed with oil to prevent wear, and the oil is collected and recirculated; it is estimated that it will only use one barrel of oil a year.”   Follow us to keep up to date with the exciting developments happening at our United Downs site over the coming months, as we prepare to switch on the UK’s very first geothermal power plant!

Wind, steam, or hydro, there is no turbine on this planet having an efficiency exceeding 30%. There is no electromagnetic generator on this planet having an efficiency exceeding 25%. Accumulatively (such as in a wind turbine), the efficiency of the turbine/electromagnetic generator combination is less than 7.5%. This means, of the energy fuelled/generated by these combined machines, more than 92.5% of this generated energy cannot be consumed by us. (100% of this generated energy is detrimental to our environment). This further means that there is the potential to increase the efficiency of the turbine/generator combination by more than 13 times,,,, 1,300%. Or,,, one wind turbine should produce/generate the same energy as 13 equally sized existing wind turbines.   The “flow” of energy in generators and turbines can only be fractionally defined by Newtonian physics. As such we are unable to measure or even contemplate more than two-thirds of the energy generated/produced by these individual technologies. This monumental hole in our science gives rise to and perpetuates delusional notions of FREE ENERGY machines. We cannot continue to power this planet with technologies upholding archaic and backward physics. 

All roads on the #EnergyTransition journey are paved with #NaturalResources. In 2023, estimates are $1.0 trillion of metals were used to built renewable power. Quote from Material World by Ed Conway -“Consider what it takes to replace a small natural gas turbine, pumping out 100 megawatts of electricity, enough for up to 100,000 homes, with wind power. You would need around 20 enormous wind turbines. To build those turbines you will need nearly 30,000 tonnes of iron and almost 50,000 tonnes of concrete, along with 900 tonnes of plastics and fibreglass for the blades and 540 tonnes of copper (or three times that for an offshore wind farm). The gas turbine, on the other hand, would take around 300 tonnes of iron, 2,000 tonnes of concrete and perhaps 50 tonnes of copper in the windings and transformers. On the basis of one calculation, we will need to mine more copper in the next 22 years than we have in the entirety of the past 5,000 years of human history.”

Wind turbine nodding, also known as 1st tower fore-aft, refers to the movement of the tower in the direction of the wind. This phenomenon can lead to fatigue and, in extreme cases, catastrophic failure. As such, it's essential for engineers to verify that a wind turbine design can withstand site-specific fatigue loads throughout its entire design lifetime. The dynamic behavior of the blades and nacelle must be separated from the tower in terms of structural natural frequencies to prevent resonance. If the frequency of the blade's torsional or transversal modes is close to that of the tower, nodding resonance is likely to occur. To mitigate this issue, engineers must consider system-level design, ensuring that the wind turbine's components are designed to work together harmoniously. Neglecting this aspect can lead to problematic consequences. Note: This illustration is a scaled-up version of wind turbine nodding, intended to help visualize the phenomenon easily. In reality, the movement is much more subtle and not as exaggerated as depicted here.

QUESTION: Does the method of Blade Testing shown in the video reflect how it was engineered and consistent with the real world in confronting the forces of nature while operating at harsh conditions? Answer: No! it doesn't reflect and is inconsistent. Only a few were addressed. My Engineering Career was spent in technical reviews of more than millions of Engineering Documents from Multi-Billion US Dollar Projects Internationally such as: Design Criteria and Specifications, Load Combinations, Hardcore Engineering Calculations, Engineering Drawings, Shop Drawings, And Construction Methods. As a Technical Person in Authority, I Comment, Reject, and Approved before a particular structure is allowed to be built to protect the interest of the Owner. Our Free of Charge Technical Review on this Blade Testing topic: 1. The reciprocating movement shown does not represent the wind loads acting on the blade. That reciprocating behavior is done by a seismic force not by wind force. The wind force attacks in one direction normal to the blade's exposed area with a sustained magnitude of force until the blade breaks. Have you ever seen an erected windmill behaving in that manner? None! That's O.A. 2. How And Why does the blade break? The wind industry oftentimes flaunts that the composite materials they use made up of layers of carbon fibers and epoxy resins are highly rated strength and lightweight. They are correct but half-truth. Here is a complete statement, the composite materials forming the blade is only high strength in tension, but is very weak in compression. That is the reason why turbine blades failed in the compression side when they fold at the weak point, that's where the compression point is identified. 3. Is there a fix for weak compression ? Answer : In the construction of buildings, the compression resistance is efficiently resisted by high-compressive strength concrete material, while the tensile resistance is resisted by steel bars to balance the defense mechanism against the destructive forces both compressive and tensile. Blades missed the balance. 4. So, how to strengthen the compression side of the blades because it can't use concrete material? Answer: This is an unfixable problem, and is the main reason why no Windmill can survive a moderate hurricane/ Cyclone/ Typhoon above 150 to 250 KPH windspeed head-on. 5. What measures the Windmill industry has taken so far to fix the compression weakness? Answer : Very little, they put additional framing made up of light materials like wood/ aluminum/ others to add a little resistance. Why very little? because if they make bigger frames, the blade will become very heavy and would not spin due to being overweight and also the cost of blades would become uneconomical. 6. Is there any other efficient means? If there is, you won't be seeing any blade breaking again while on duty or at the very least no cracking. This is an independent technical opinion.
