Due to climatic change, new ways for the production of sustainable fuels are being investigated and one is to use sunlight to recycle CO2, combine it with water and convert it into hydrocarbon-based fuels. However, although this concept is very attractive, this process, often called artificial photosynthesis, is not yet…

Wood as additive manufacturing

A Swedish Company specialized in doors and windows, uses a 3D BLB printing machine with different bio-composites. Bio-composites are products of plant origin such as wood, straw, cork, etc., mixed with a polymer. They are capable of printing 2,5 x 1,5 m. It currently offers materials with 50% wood fibers…
The Company Arpa from Zaragoza, experts in the design, manufacturing and installation of mobile campaign equipment for isolated or conflicting areas, in order to lead the change to a more sustainable world has launched the Arpa Change. A hybrid photovoltaic installation capable of generating energy and hot in a single…
Lightyear has provided the world’s first electric car with solar recharge and with a “long-range” autonomy, up to 725 kilometers of autonomy (in WLTP cycle), and which is postulated as a clear Tesla competitor. The model is called Lightyear One and it can charge its battery directly with the sun…
New light-emitting diodes, or LEDs, have been created from a nanomaterial that emits ultraviolet light. It is the first time that someone creates ultraviolet light on a graphene surface. According to its developers, from the Norwegian University of Science and Technology (NTNU), it is a new electronic component that has…
Finally! 10 years later, the “Generalitat” of Catalonia plans to give a boost to renewables in the region. The Government has initiated the procedures to repeal the so-called anti-renewable decree of Catalonia. This is Decree 147/2009, of September 22, which regulates the applicable administrative procedure for the implementation of wind…
Stronger and more flexible than graphene, a boron layer of a single atom could revolutionize sensors, batteries and catalytic chemistry. Not long ago, graphene was the wonderful new material. A super strong sheet formed by atoms in the shape of a chicken coop, which can form tubes, balls and other…
Using a technique of statistics and artificial intelligence, known as clustering, scientists from the Solar Energy Institute of Polytechnic University of Madrid (IES – UPM) and the Institute of Micro and Nanotechnology of the Higher Council of Scientific Research (IMN-CSIC) have found a practical way to include in your calculations…
The growing hybrid or electric automotive market has given the definitive impulse to the massive use of lithium batteries in dimensions and quantities higher than those simply incorporated into uses with smaller powers or as storage of domestic photovoltaic installations. To this, it can be added the large storage stations…

Green energy from wine production waste

Thursday, 21 March 2019 11:30
The transport sector contributes about 28% to the world’s primary energy consumption, and more than 90% of its consumption comes from petrol. For this reason, different International policies promote the transition of the use of petrol in transport by other sources of energy, such as electricity and biofuels. Although biofuels…
