Engineers at the University of Harvard are using the glassy skeletons of marine sponges as inspiration for the next generation of stronger, taller buildings, longer bridges and lighter spacecraft. The researchers have shown that the skeleton’s
square grid-like structure with diagonal supports has a better strength to weight ratio than traditional lattice designs that have been used in the construction of buildings and bridges for centuries. Source: Harvard University https://bit.ly/3j7dtDp

Electric highways will help to reduce emissions from goods transport The electrification of 7,500 kilometres of the most important road network in the United Kingdom
will allow most lorries to be powered by overhead catenary cables. This would make a significant reduction in carbon emissions. Engineers at the University of Cambridge have proposed the construction of an electrical charging system that would help to eliminate 65% of the carbon emitted by lorries driving in the United Kingdom. Not only is the project feasible, it is easy to scale up. Source: University of Cambridge https://bit.ly/3idguBb

Silicon for carbon in circuits Using carbon instead of silicon for transistors can make computers faster while reducing their energy consumption a thousandfold. A team of chemical and physics engineers from the University of California have made a huge step forward in their research to create carbon-based transistors. The new carbon-based metal is derived from graphene and has excellent conductive properties. Source: University of California, Berkeley https://bit.ly/2FV1Pxo

2. ENGINYERIA ELECTRÒNICA Un equip d’enginyers químics, juntament amb físics, de la Universitat de Califòrnia, ha substituït el silici pel carboni en els transistors dels circuits dels ordinadors, per tal d’augmentar la velocitat dels ordinadors i disminuir l’energia consumida.
3. ENGINYERIA ELÈCTRICA A la Universitat de Cambridge un grup d’enginyers s’ha proposat construir un sistema de carretera elèctrica i electrificar 7.500 quilòmetres de la xarxa viària més important del país. Això permetrà alimentar la majoria de camions amb cables de càrrega aèria.
