Ewicon. ‘Challenge the future’ is the motto of Delft University of Technology (TU Delft), one of the leading technical universities in Europe.


Therein lies precisely the focus of the Faculty of Electrical Engineering, Mathematics and Computer Science’s (EWI) research into alternative energy generation. The prototype EWICON (Electrostatic Wind energy CONvertor) was designed as part of this research. The technology was developed by the EWI faculty in partnership with Wageningen University and Research Centre and commercial parties as part of an economy-ecology-technology government programme. The revolutionary wind energy convertor transforms wind energy into electricity without the use of moving mechanical parts, resulting in significantly less wear and tear, lower maintenance costs and no noise issues or overshadowing.

This makes the turbine ideal for offshore installations or in the city, for instance on a high rooftop. Saphonian bladeless turbine boasts impressive efficiency, low cost. אנרגיה nrg - רק בגלל הרוח. רותי רוסו, המגזין | 15/6/2006 10:27 על גג פח לוהט, באזור התעשייה של ראשון לציון, ניצבת מעין אנטנה מסתובבת לפותה בחבלים לבסיסה.

אנרגיה nrg - רק בגלל הרוח

במבט ראשון היא נראית כמו אלתור יצירתי לקליטת שידורי המונדיאל, אבל ההסבר שמציג האיש שבנה אותה, ד"ר סרגיי רוזנברג, מבהיר כי ייתכן שמדובר כאן ביצירה בעלת פוטנציאל מזומנים עולמי, שאולי תשנה את שוק האנרגיה כפי שאנו מכירים אותו. האנטנה היא למעשה טורבינת רוח לייצור חשמל עצמי. נכון להיום ההספק שלה מגיע לחמישה קילוואט בשעה (קוט"ש), שזה יותר מצריכה ממוצעת של וילה מצוידת היטב ומאוכלסת באנשים פזרנים במיוחד. רק לשם המחשה, צריכה של חמישה קוט"ש תביא לחשבון חשמל של כמעט 1,500 שקל בחודש. הטורבינה שייצר רוזנברג, איש בעל אוריינטציה סביבתית עמוקה, נועדה לענות על דרישות מחמירות של ייצור אנרגיה מתחדשת - יוזמה שעדיין איננה מלוטשת וגמורה באופן סופי. אם הם אכן צודקים, ייתכן שבשיבושים הבאים של מונופול החשמל הישראלי, במקום לשבת בלי מזגן ועם מחשב שקרס בחושך, נוכל לצחוק ולהעביר ערוצים בטלוויזיה במקביל.

Possible Dual Rotor Technology for Wind Turbines

The engineers studied the base of existing turbines and found two major problems. Startup Offering Wind Turbines That Look Like a Tree and Sound Like One Too - Business - Haaretz. Wind turbines have been touted as one possible answer to global warming, but they're terrible for birds and bats, they're noisy, and they're an eyesore.

Now, a French startup is announcing the Wind Tree, a small, silent version that it says is ideal for cities. Advantages and Challenges of Wind Energy. Wind energy offers many advantages, which explains why it's one of the fastest-growing energy sources in the world.

Advantages and Challenges of Wind Energy

Research efforts are aimed at addressing the challenges to greater use of wind energy. Read on to learn more about the benefits of wind power and some of the challenges it is working to overcome. It's a clean fuel source. Wind energy doesn't pollute the air like power plants that rely on combustion of fossil fuels, such as coal or natural gas. How Do Wind Turbines Work?

How Do Wind Turbines Work?

So how do wind turbines make electricity? Simply stated, a wind turbine works the opposite of a fan. Instead of using electricity to make wind, like a fan, wind turbines use wind to make electricity. טורבינות רוח. WIND%20TURBINES. Solar Wind Energy's Downdraft Tower generates its own wind all year round. When we think of wind power, we generally think of huge wind turbines sitting high atop towers where they can take advantage of the higher wind speeds.

Solar Wind Energy's Downdraft Tower generates its own wind all year round

But Maryland-based Solar Wind Energy, Inc. is looking to turn wind power on its head with the Solar Wind Downdraft Tower, which places turbines at the base of a tower and generates its own wind to turn them. Described by the company as the first hybrid solar-wind renewable energy technology in the renewable energy market, the tower at the center of the system generates a downdraft that drives the wind turbines positioned around its base. Invelox wind turbine claims 600% advantage in energy output. SheerWind, a wind power company from Minnesota, USA, has announced the results of tests it has carried out with its new Invelox wind power generation technology.

Invelox wind turbine claims 600% advantage in energy output

The company says that during tests its turbine could generate six times more energy than the amount produced by traditional turbines mounted on towers. Besides, the costs of producing wind energy with Invelox are lower, delivering electricity with prices that can compete with natural gas and hydropower. Invelox takes a novel approach to wind power generation as it doesn’t rely on high wind speeds. Instead, it captures wind at any speed, even a breeze, from a portal located above ground. Hanging Underneath A Bridge Is A Great Place To Put Wind Turbines. Viaducts—the technical term for arch-supported bridges—are already impressive swoops of engineering prowess.

Hanging Underneath A Bridge Is A Great Place To Put Wind Turbines

But this kind of infrastructure is about to get even more amazing, as giant spinning turbines are hung from the spans. The Juncal Viaduct in the Canary Islands is serving as a model for the project, completed by researchers from Kingston University in London. The scientists' calculations show that installing turbines between its tall legs would produce enough power for 450 to 500 homes, or around half a megawatt.

"This kind of installation would avoid the emission of 140 tons of CO2 per year, an amount that represents the depuration effect of about 7,200 trees," Oscar Soto, a researcher on the project, told the Spanish-language SINC. World’s First Airborne Wind Turbine to Bring Renewable Energy and WiFi to Alaska. Wind turbines have become airborne!

World’s First Airborne Wind Turbine to Bring Renewable Energy and WiFi to Alaska

An enormous helium-filled wind turbine will soon float over the city of Fairbanks, Alaska to produce enough electricity for more than a dozen families living off the grid. Designed and built by MIT startup Altaeros Energies, the turbine known as BAT-Buoyant Airborne Turbine will hover at an altitude of 1,000 feet for 18 months, catching air currents that are five to eight times more powerful than winds on the ground. Large wind farms floating over major cities may seem like something from a sci-fi movie, but the concept of airborne wind turbines is close to becoming reality. Altaeros has already built the world’s highest turbine that can generate twice the energy output of its ground-based counterpart. 1012431.77417395. גודל יחסית לניצול. על זה אני רוצה לדבר איתך.
