The new wind generator
Two Basque companies, Enerlim and NECESA, have developed a new wind generator, a wind reservoir to make use of wind energy.
This wind reservoir is much lighter than ordinary three-arm wind generators; hence, it is more economical and easier to install. On the other side, the machine is completely modular, as columns, pulleys and plates can be divided in order to make easier the production, transport and installation. The largest piece to be transported and installed is 12 meters long and 2.5 Tm. Therefore, it is not necessary to use special trucks or roads and neither huge cranes. In addition, only the structure can be seen from a distance of 4 meters. As a consequence, the environmental impact of this system, according to their promoters, is low. Neither does it involve any danger for birds, because the maximum speed of the plates is 40 km/h, and they can easily avoid them.
The wind reservoir is based on two columns of 25 meters high and there is a distance of 135 meters between both of them. Each one has three pulleys of 3 meters diameter each and they are located at different heights. Those pulleys conduct steel cables that are moving between the two columns. Perpendicular to the cables there are 53 plates, each with 25 kilograms, 12 meters high and 25 meters wide. Next to each pulley of one of the columns there is a generator of 100 KW.

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
