El Instituto Tecnológico de la Energía (ITE) ha presentado en Bruselas dos proyectos relacionados con aspectos claves para el desarrollo del vehículo eléctrico y un sistema de eficiencia energética que permite reutilizar el agua caliente sanitaria y reducir el consumo de energía en un 85%. También ha dado a conocer un sistema que permite controlar a distancia las instalaciones de generación eléctrica. En el marco de la presentación en Bruselas del libro 'Redit 14 razones para innovar', el ITE ha presentado el diseño del cargador eléctrico de Renault elaborado por la empresa GND, adaptado a la normativa relacionada con la compatibilidad electromagnética, punto clave en la investigación del vehículo eléctrico. Además ha presentado la Estación Inteligente de Recarga (EIR) de vehículos eléctricos de Electric Lloc, que se ha convertido en referente nacional de este sector –afirma el Instituto–, al aportar avances en cuanto a hardware y software.

El Centro Tecnológico Avanzado de Energías Renovables (CTAER) ha contratado a Abengoa para que construya una instalación única en el mundo. Ha sido bautizada como ―Central Solar de Geometría Variable‖ y tras ese nombre está un catedrático de termodinámica de la Universidad de Sevilla llamado Valeriano Ruiz. La novedad que aporta Central Solar de Geometría Variable estriba en la movilidad de sus elementos. Hay una torre central y un campo de helióstatos, pero con la particularidad de que los helióstatos se asientan sobre unos soportes móviles, unos raíles circulares concéntricos en relación a la torre, que permiten el movimiento alrededor del receptor.

El desarrollo de dispositivos electrónicos flexibles se está

convirtiendo en algo bastante habitual tanto en líneas de producción como en el ámbito de la investigación. Dentro de estos desarrollos hemos visto que gran parte de los esfuerzos se centran en el uso de sustratos plásticos y,

por otro lado, en el uso de nanotubos de carbono como

base de una estructura flexible pero a su vez robusta. En

la Universidad Estatal de Carolina del Norte han seguido

la senda de los nanotubos de carbono y parece ser que han desarrollado un método de fabricación de conductores elásticos basados en este material, un trabajo que podría servir de base al desarrollo de una nueva generación de dispositivos electrónicos elásticos y flexibles.
