Innovative wind turbines in design

Recently, the International Energy Association (IEA) announced the global renewable energy source for the first time over coal energy, in which wind energy accounts for a large proportion. Currently, new technological innovations in wind turbine design are no longer a mystery and become the fastest growing form of clean energy sources. Engineers have developed new equipment that is more efficient, safer for humans and animals.

1. The world's first wind turbine

Typhoon wind turbines invented by Atsushi Shimizu to exploit a large amount of energy contained in storms often hit Japan. He estimated that a storm containing a huge amount of energy could power the nation for 50 years if exploited.

This system is designed to withstand the terrible wind from storms, has an isotropic shaft system and can customize the rotational speed of the rotor. Tests have been carried out and the results are promising. Shimizu is currently on a mission to connect with investors to build larger realistic versions in the hope that someday in the future will be able to use the energy from the storms to supply the network. National electricity.

2. Wind turbines with wind and water

How does a wind turbine generate electricity when there is no wind?

Certainly with traditional turbines this is simply not possible, but a new project from Max Bögl Wind AG and GE Renewable Energy allows the connection of traditional wing turbines with hydroelectric technology to create power generators The first hybrid in the world - combining wind and water. The German Swabian-Franconian Forest project will start with four wind turbines with a capacity of 13.6 MW. The first phase is expected to connect to the grid in the next year, and the second phase will add a 16MW hydroelectric plant expected to be completed in 2018.

3. Wind turbines in the air

While most wind power projects are firmly placed in the ground or at sea, a number of recent initiatives have taken turbines up in the sky, where the wind moves fastest. The first aerial wind turbines launched in 2014 in Fairbanks, Alaska are called BAT-Buoyant Airborne Turbine designed and built by MIT Altaeros Energies, located at 1000 feet (equivalent to 300m) thanks to helium and shaped gas. shaped like a giant cylindrical balloon. This wind turbine takes advantage of 5-8 times more powerful wind energy than on the ground. The 18-month experiment created enough energy for dozens of households. Due to its high position advantage, the BAT system can also transmit WiFi and mobile signals, as well as weather sensors.

4. Wingless wind turbine

Bird safety when flying near wind turbines is a problem. To reduce the danger, engineers created the Vortex Bladeless generator, shaped like a large, thin straw instead of the usual fan blades, helping to harvest energy from the moving winds. air. Because this system occupies a small area, some can be installed in the space of a single-blade turbine turbine. The founder of Vortex Bladeless emphasizes equipment that cuts production costs by 53% and maintenance costs by 80% compared to traditional turbines.

5. Hopper wind turbine

This innovative wind turbine is capable of producing 600 times more energy than traditional windmills. SheerWind Invelox Turbine is a funnel-shaped wind power generator that harnesses the wind on the ground and increases the speed of the internal wind thanks to the miniature funnel-shaped structure and many sudden knots. The system can operate even in low wind conditions and because there is no external wing rotating at high speed, it does not pose a danger to local wildlife. This device is also less expensive to build than traditional wind turbines.

6. Wind turbines are friendly with birds

This is one of the oldest designs on this list, as the 89-year-old veteran Raymond Green was also a design bird lover in 2012. He named this wind power generator as the Catching Wind shaped. like a funnel and giant speaker. The wind will enter and then be compressed to create more energy at the internal turbines. This wind turbine has no moving parts so it does not threaten birds when they fly by. Green has expanded this system and hopes that both residents and industrial zones can create renewable energy without endangering birds.
