Cartif of Valladolid Foundation, the Center for Renewable Energy Development (Yield) CIEMAT (based in Lubia, Soria) and the company Unisolar, the town of Bejar Salamanca, have begun this year a research project that is intended to be aimed at developing a hybrid plant with two renewable energy sources (biomass and solar photovoltaic solid) capable of generating electricity and heat to provide a solution to energy supply in isolated areas as Latin America. The project, called Hibrelec, is an important aspect of development cooperation for these communities.
“It focuses on building a small biomass plant hybrid photovoltaic solar energy which is intended to provide power in isolated locations that do not have a good connection to the electricity grid,” explains researcher Ceder DiCYT Luis Saul Esteban. The scientist, who coordinates the works in which the center of CIEMAT, believes that these facilities are “viable in the medium term” and may represent “an important contribution to isolated communities.” The work began about two months ago with the search for potential sources of biomass in the three participating countries in the Americas: Chile, Colombia and Cuba. The Ceder involved in the design of gas cleaning system invocrudados in the gasification process, “important for the proper functioning of the engines.” The research, taken together, is coordinated by the Foundation Cartif.

Fifty years after the invention of the laser, a team of scientists from Yale University (USA) has built the first AntiLaser the world. With an inch in diameter, this development could have applications in the new generation of computers “optical” and radiology.
“The device absorbs the incoming laser energy and transforms light rays into electricity or heat”, told SINC A. Douglas Stone, a researcher at Yale University (USA) and member of the team that developed the first AntiLaser the world.
The mechanism, called “perfect consistency buffer (CPA for short in English), two laser beams focused to a specific frequency within a cavity that contains a disk of silicon as semiconductor material. The hard lines of light waves that bounce off indefinitely until absorbed and converted into heat, as detailed in the article published today Science.
Fifty years after the invention of the laser, “the running AntiLaser Optio fundamental process that has not been studied so far,” said Douglas Stone. It is, therefore, a laser that works in reverse: absorb light at specific frequencies rather than emitting it.

Researchers from Nanophotonics Technology Center at the Polytechnic University of Valencia are working on developing the next generation of flexible photovoltaic panels within Silicon Light of the European project, coordinated by the Centre for Energy Research of the Netherlands (ECN).
This type of panel, made of plastic and weighing less than 1kg/m2 is particularly useful for areas with limited way, roofs that do not support much weight and in other applications such as awnings, mobile tents for events, tents for humanitarian campaigns and even in the sails of a sailboat to power the boat.
“These are structures that allow power supply quickly, easily and at low cost facilities and areas that can not support much weight. They are also very simple to install, in fact, unlike traditional panels, these ‘rolls of plastic photovoltaic’ can be installed in minutes, “said Bill Smith, a researcher at the NTC.

Researchers at the Robotics Group Vision and Control at the University of Seville with the Systems Engineering and Automation University of Malaga to develop a system that combines traffic monitoring cameras and distributed sensor networks to overcome the current difficulties control devices. This is an excellent research project which the Ministry of Economy , Innovation and Science has funded 103 800 euros.
The traffic monitoring systems have been developed in recent years are based mostly on visual images from cameras or sensors centralized. Therefore have limitations due to variability in lighting conditions during the day and night, the presence of phenomena that limit visibility such as fog, rain or smoke, and the complexity of the stage with forks , tunnels or changes of direction.
To overcome these obstacles, researchers Vision and Robotics Group Control of Universidad de Sevilla together with the Systems Engineering and Automation of University of Malaga is developing a 3D system for detection and traffic monitoring cameras and combining distributed sensor networks .
Experts propose a sensing system based on several different devices such as cameras with multispectral bands , ie that detect different parts of the spectrum – which will be added to nodes containing various sensors distributed throughout the road.

Students and professors of the School of Industrial Engineering at the University of La Rioja have created ‘Zemic (Zero Emissions Pollutants)’, a project-driven electric car generates no emissions harmful to the environment or produce noise. It also has superior performance to diesel and gasoline engines, and a system recovery of braking energy.
This ‘vehicle powered entirely by electricity’, as it is called in the project, has the chassis of a buggy, three batteries, an electric motor and a series of modules that will power systems control.
CO2 emissions generated by the transport sector in our country accounted for 29.8% of the total (at European level, 32.1%). They are caused by propulsion systems currently used for road transport, diesel engines, gasoline engines and heat engines, which produce CO2 emissions, noise pollution, emission of particulates and other toxic gases (hydrocarbons).
In addition to the inefficiency of such machines (more than half the energy produced is lost as heat) are not able to harness the energy of motion of the vehicle or recovered may be lost as heat in the discs brake.
In contrast, the electric motor supports the recovery of energy under braking and also has other advantages: the energy required for the manufacture of batteries is higher than that required for the processing of gasoline, and mineral resources (lithium ) which are essential raw material are more widely spread in world geography.

Scientists at the Universitat Politecnica de Catalunya (UPC) has designed a new system for determining “a simple and objective” color and stains the skin using a computer and a camera, which will study the chromatic variations in the dermatological treatments, according to a study published in the latest issue of the journal Skin Research and Technology.
Josep Pladellorens Professor, Department of Optics and Optometry of the UPC and one of the authors of the study, explained to SINC that this technique avoids subjective perceptions in the analysis of skin colors, besides being cheaper and easier to use than the
traditional spectrophotometer, “and without noticeable loss of precision in the results.”
The system requires a digital camera connected to a
computer with CCD, illuminating the skin with a constant light source to standardize the various shots. Once recorded the image, identifies a specific software CIELab coordinates, a model that fits Colorimetric “enough” to human perception, which quantifies the colors by analyzing luminosity ( “L”), the balance between red and green ( “a”) and balance between yellow and blue
