Advances in Wind Energy: Wind Turbine in Low Winds

On September 18 was presented at the German fair Husum Wind Energy a new wind turbine with which it is possible to use the low winds, which means that we will have at our disposal more amount of wind energy.

While they are still designs, is expected for the second quarter of next year we can know in detail the first prototype which will be installed in in Osterild (Denmark).

The features of this new V126-3.0 MW with a rotor diameter of 126 meters which makes it perfect to take advantage of the low winds and, in turn, is one of the ways in which we will be able to differentiate them with its design of blades with structural shells.

In turn, as experts say, expected that with this type of design are to see reduced investment spending continues to maintain the high quality of the wind turbines.


This type of wind turbine has an area of greater, in particular sweep, a 27% more than the old turbines thanks to their shovels of 62 metres.

In turn, this type of wind turbine will make less noise reducing noise pollution.
This type of wind turbines require a prior measurement of the speed of the wind taking place thanks to the measuring towers.

There are different types of anenometros among them of three hemispherical cups that you've probably seen in any wind farm because it is the most widely used today.


Although, I have to tell you, that these towers are also used in aviation, marine, etc.

Definitely, this kind of products as V126-3.0 MW gives us a bit of encouragement and hope to those who support renewables since this means that increasingly enhance more values pro environment.

ES Pipe Waterwheel Concept Transforms Regular Water Supply into Mini Turbine

For residents of third world countries, access to regular water and grid electricity remains sporadic.

Even though the supply of clean drinking water has improved greatly with people tapping into ground water using bore wells, the supply of constant electricity remains elusive and many people are doomed to fight the dark of the night using oil-lit lamps or use the limited power a battery backup can provide.

For the underprivileged population in places like Africa, designer Ryan Jongwoo Choi has designed the ES Pipe Waterwheel concept which has the ability to turn regular plumbing into a mini hydroelectric generator.

One of the finalists at the 2012 IDEA award (International Design Excellence Award), the concept calls for a special intermediate plumbing fixture that can be attached to regular plumbing pipes.

Each time the tap is turned on, the flow of water through the pipe passes through the installed waterwheel which turns the Kinect energy from the flowing water into electricity that can be used to power light bulbs.


The installation generates clean power and only utilizes the energy created by the flow of water which is otherwise untapped. The easy to install and easy to detach waterwheel stores the power in a battery and the user can easily detach the gizmo and use the portable light wherever it is needed.

 The ES Pipe Waterwheel concept can also be used with hoses to make the process of installing and uninstalling more convenient.

Wind turbine prototype extract water from the air

In desert areas, easy access to the water is a problem, you have to carry enough water or ensure the route to power supply. However the lack of water in desert or semi desert could be solved thanks to this prototype turbine which extracts water from the air.

The wind turbine is called Eole water, its creator Marc Parents came up with the idea while living in the Caribbean. Frames Parents wanted draw water through a renewable energy thinking in areas that did not have easy access to electricity, after 10 years of r & d has achieved the wind turbine WMS1000, able to condesar and store up to 1,000 litres of water a day.

L turbine Eole water is already a reality, has been built in Abu Dhabi 6 months ago and has managed to produce between 500 and 800 litres of water per day, could get 1,000 litres a day implemented a system of Tower. With this test he has failed to demonstrate that the system works. Now the company is working with several manufacturers to produce new turbines.

It is 34 meters tall, requires winds of at least 24.14 kilometres per hour or more, to turn the rotor of 13 meters in diameter and thus generate enough energy. It produces 30kW of sufficient power to operate the system.

The air is sucked through a few holes of the turbine and generator achieves the occurrence of steam. Steam is distributed through a compressor cooling to form the humidity that condenses into water. The liquid retrieved is channeled to a tank of storage located at the base of the turbine after having been purified.
If the turbine is installed in an area that meets the requirements of the wind speed, the system is completely autonomous. It achieves its objective, a mass storage of water even in very arid or desert locations.

The turbine Eole water it has a great potential for water supply in arid areas, but also offers other facilities:
-Ensure a supply of water in isolated areas who do not have a reliable supply warehouse
-Supply of water in emergency zones where there has been some disaster,
-Provide water for organic farming, where achieving water with a system based on renewable energy is an interesting option.
 

Turbine wind, violet

The Wind energy, basically, is the transformation of air in electrical power or other useful forms of energy obtained by autogeneradores which are placed in the so-called Wind turbine, that together and grouped together make up a Park wind Kinetic energy.

However not everything is as favourable as it seems that while the use of this form of energy is sufficiently viable is noticed recently a serious problem in regards to creatures which are mobilized through the air.

These wind turbines threaten many birds and bats, by having a white or light grey which, as many know, attracts remarkably large number of insects, which in turn make come to hunt, becoming injured painting and until dead during operation.

The solution proposed by the researchers, who noticed this attraction colors both day and night, is that these turbines are painted in a glossy violet, enough as to prevent this attraction between hunters and prey that is detrimental to a large number of species.

To this research, currently in development, the influence of heat produced in the turbines has been added and their influence on echolocation ability allows to bat dodging obstacles and objects during his flight, a topic that has already been addressed in Erenovable but from another aspect.
