"This the best until we will make the better one". You probably encounter within a similar sentence of VW commercial. Denmark's Vestas has the connotation in accordance with being best but in a different area; Wind Turbine.
MHI Vestas Offshore Wind unveiled its uprated 8 MW wind turbine, enabling its 8 MW platform to reach 9 MW at specific site conditions. The company’s prototype at Østerild broke the energy generation record for a commercially available offshore wind turbine on Thursday 1st December, producing 216,000 kWh (actual figures 215,999.1 kWh) over a 24 hour period. What do you think about competition up to now? Vestes is the commander in chief. Let's look up the wind turbine league: http://www.windpowermonthly.com/10-biggest-turbines The new V164 can reach a rated power of 9 MW depending on specific site conditions. The increased energy production per wind turbine will add greater value for many projects and save on Capital Expenditure (CAPEX) costs as fewer machines will be needed to meet the park capacity. “We are committed to delivering turbine technology that is in line with the development of our industry, based on our 20+ years of offshore experience. Reliability remains a key enabler, and our approach to developing our existing platform supports this strategy,” said Torben Hvid Larsen, CTO. “Our prototype at Østerild sets yet another record for power production, producing 216,000 kWh over a 24 hour period. We are confident that the 9 MW machine has now proven that it is ready for the market and we believe that our wind turbine will play an integral part in enabling the offshore industry to continue to drive down the cost of energy.” The 9 MW wind turbine is part of the product portfolio designed to deliver affordable offshore wind power. The turbine is based on the V164-8.0 MW, a machine already installed at the 258 MW Burbo Bank Extension, and which has a firm order book of over 1.6 GW. Installation of the first project with the most powerful serially produced turbine was successfully completed on 14 December 2016, utilising the V164-8.0 MW. MHI Vestas has further developed this platform in a continued commitment to deliver affordable offshore wind power. Source: http://www.mhivestasoffshore.com/new-24-hour-record/

Have you ever heard Hudway ? At first look, you suppose that they probably use hologram technology that is absolutely false and cost up to build such a gadget. The company, unveiled in kickstarter, has designed a gadget which reflects your route to windshield. The idea is based on the basic law; reflection. Even if the idea is simple, the design is novel: What do you prefer horizontal or vertical ? You do not have to make a choice. Tunisian company Tyer Wind has been working on a novel design that use structure and working mechanism of Hummingbird Wings. Either horizontal or vertical, wind turbines have several disadvantages as vibration, bird carnage, noise, installation cost, etc despite of green energy production. The company has recently issued an introduction on Youtube which has no information regarding efficiency as below: What are the advantages of this novel design ? Efficiency: TYER is a highly efficient wind converter as confirmed by our in-house tests. Such performance was made possible thanks to its revolutionary kinematics, its aerodynamics features (It generates work during both downstroke and upstroke) and its smaller swept area (as compared to other wind convertors) Integrity: Tyer wind converter is able to convert the resultant force of the lift and the drag forces into work and has, therefore, limited level of drag at the structure. This has 2 major advantages: (1) Lower solicitation at the mast resulting in lower civil works costs, (2) Tyer wind converter can resist high wind velocity and therefore can generate higher energy output. On the other hand, and since the wings are based on an ocillating concept, Tyer converter generates limited vortex (as compared to that created by turbines) which would be tranquilized backwards quite quickly allowing a higher density of installed machines (in a wind farm). Ecology: TYER wind converter is a perfect illustration of Bio design that mimics Nature. The machine has a great landscape integration potential and limited visual impact. It is also bird friendly and could be adapted to any environment (rural or urban). Source: Tyer Wind Plus: Hummingbird is in a Wind Tunnel. Let's check this amazing sweety birdy Aerospace company Pratt & Whitney is integrating its new PW1000 PurePower engine into modern aircraft. The company wants to make them 15 percent more efficient using an unconventional approach to turbine engines.
Pratt & Whitney is renowned for its aircraft engines. Now the company wants to improve the traditional design of jet engines and reduce the impact of supersonic turbulence. The solution is remarkably simple, yet highly sophisticated. Instead of using a solid shaft which links the compressor to the turbine, the team introduced a gearbox to alter the speed at which the compressor spins. Spinning the compressor slower seems counter intuitive, however, by spinning the blades at subsonic speed, the turbulence is minimized, achieving an optimal speed to best improve efficiency. Previous tests revealed the engine is 15 percent more efficient, and since the compressor no longer runs at supersonic speeds, the sound is significantly reduced as no shockwaves are created. In fact, up to 75 percent of the noise can be reduced. Traditional turbine engines rely on a compressor to feed air into and around the combustion chambers. The majority of the air cools the engine while a small portion is used for combustion to rapidly accelerate the gas into the turbine. The turbine uses some of the energy from the gas to spin up incredibly fast. Both the compressor and the turbine are connected to a shaft resulting in both to spin at the same speed. The engine works remarkably well. The more gas passing over the turbine blades, the faster it will spin. This causes the compressor to spin faster and pull in more air, thereby feeding the turbine more air to combust, creating more power and the cycle continues. It seems like an ideal scenario: the faster the turbine spins, the more air, and therefore the more power. The theory is true for the most part, until the compressor blades reach the speed of sound. Reaching the speed of sound creates an intense shockwave. Anyone who has heard a shockwave understands the shear power exerted by such a force. The shockwaves contain highly compressed and uncompressed waves which travel in series in the form of turbulence. Since the turbine blades are not very large, the shockwaves impede on the compressors ability to force in more air. As a result, the fuel efficiency is severely impacted. Achieving such an impressive reduction was no easy task. Pratt & Whitney invested over $10 billion and 20 years in perfecting the Geared Turbofan engine. The engines are much quieter, fuel efficient, economical, and environmentally friendly. Some airlines have already incorporated the new engines into their fleet, leaving the skies a little more green.

Vacuum cleaner is an option to apply easily but not the exact method to complately cleaning process. So, what is the method that metal powder could be cleaned up entirely ? We absolutly need interaction. Magnetic force is the method to picking up every piece of powder from ground. Scientist from Rice University in Texas and Kazan University in Russia who have discovered a method to dispose radioactivity from water has been working on this smart idea and they have finally found the right (and also cheap) material to realize the method. Oxidatively modified carbon (OMC) which removes the radioactive strontium and cesium out of the water. It purifies the water to a level that makes it safe to be poured back into the ocean.
They have recently published an article related the method in Journal of Carbon: http://www.sciencedirect.com/science/article/pii/S0008622317300350 Detailed information could be obtained: |
