Cooling without electricity

Friday, 22 November 2019 09:18
The process is called radiative cooling and consists of blocking sunlight to avoid heating. At the same time it radiates infrared light that is directed to the atmosphere, cooling down the device noticeably below room temperature. It is a special isolation, called air gel, composed of polyethylene foam and that…
The production of batteries for electric vehicles is growing and Europe does not want to lose ground to Asian manufacturers. China, for example, is the producer of 61% of the batteries, so it would be interesting to start producing in Europe, and Spain could be one of the countries where…
Thermosetting compounds are formed using fiberglass, carbon or aramid, which is combined with resins such as polyesters, vinyl esters, epoxies or phenolic resins. These compounds are used in various sectors, but they stand out in particular in the manufacture of aircraft or spacecraft parts. Thanks to the research and development…
An American company, specialist in refueling and transfer technology of fluids and gases, has developed a revolutionary coupling that greatly improves handling time and safety in hose loading and unloading processes. Until now, camlock-type couplings have incorporated safety handles that require the use of both hands for closing and opening.…

Magnetism to produce hydrogen

Tuesday, 03 September 2019 10:06
One of the most promising energy sources for the environment is hydrogen generated through the division of water, a reaction in which oxygen and hydrogen are produced. Now, thanks to researchers from the Catalan Institute of Chemical Research, this hydrogen economy is closer than ever. Researchers at the Catalan Institute…
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

Monday, 29 July 2019 07:21
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…
