Los avances en nuevas fuentes de energía no tienen que venir necesariamente del campo de los polímeros e iones de litio, y los nuevos materiales, o eso es lo que piensa Sony, que ha logrado extraer electricidad de unas láminas de cartón corrugado en cantidad suficiente como para alimentar un ventilador acoplado a un pequeño motorcito. La base del experimento, que suena como una alternativa para generar electricidad en situaciones de emergencia, se aprovecha de un efecto por el que las termitas son capaces de producir energía al alimentarse de madera, algo que ha sido transportado al campo químico, que reacciona con la celulosa que compone el cartón.
Una división de la firma nipona mostró este avance en una exibición en Tokyo, donde replicaron el experimento con un pequeño contenedor lleno de pequeños trozos de carton, el elemento químico reactivo y una base que transmitía la energía eléctrica al motor que movía el mini-ventilador. El cartón corrugado podría ser reemplazado de manera efectiva por otro material de similares características que esté fabricado con celulosa, cuya cadena de glucosa se consigue romper con unas enzimas, lo que produce iones de hidrógeno y electrones. Los electrones fueron capaces de proporcionar electricidad para alimentar el circuito, mientras que los iones de hidrógeno reaccionaron automáticamente con el oxigeno creando agua.
Por supuesto, no es algo que se pueda aprovechar como fuente de energía primaria para gadgets en un futuro próximo, sin embargo sí parece una magnífica opción, a largo plazo, para generar pequeñas cantidades de energía que sirvan en momentos de emergencia, como un fallo eléctrico generalizado, o en situaciones en las que necesitamos un respaldo. También es especialmente interesante en zonas menos favorecidas, que carecen de suministro estable de electricidad. De cualquier modo, por el momento el “pequeño experimento” de Sony produce poca cantidad de energía eléctrica a un bajo voltaje, y todavía pasarán algunos años antes de que la tecnología esté lista para su comercialización. Según la firma, este procedimiento sería adecuado para alimentar pequeños dispositivos como reproductores MP3, pero no podrá reemplazar completamente las baterías convencionales.










Y si lo prendes fuego tambien extraes su energia.
Sí sí, pero esa es más peligrosa, y no me gusta el sabor de la barbacoa al cartón :/
mientras no hagan una Play Station de cartón diciendo que no necesita conectarse a la luz …xDDD
I know it’s a weird dream, all my dreams are! I just wanna know if annoye has a meaning to offer?I had a dream I moved into like this hotel/apartment/bungalow thing in Georgia. It was absolutely disgustingly filthy. It was just crawling with HUGE insects that looked like they were from horror movies. None were smaller than my head and some were so surreally awful they looked like animated. The walls were just caked on with grime, everything was gray or dull green and even the air was just smokey with filth.I was so upset, and I kept trying to kill all these massive bugs but I just couldn’t do it. I’d get too scared or they’d run away or they would be just too big to kill.A lot of my family was there, in an upstairs area where there was a dirty pool table and a balcony. They acted like everything was fine up there; they were just drinking and talking.I was in the basement, where most of the bugs and mess was.I remember distinctly one part:I went into the backroom/bedrooms area of the basement where there were two beds and luggage everywhere. I saw this enormous green, thick caterpillar and a smaller but still huge black centipede.And they were spazzing out all around the room. The caterpillar had like, a fake face: it was this creepy smile with big black eyes, but that was just a pattern on his fur because I could see his real face under it, which was a lot like a spider’s face.And it was making this freaky squeaking noise and sometimes he’d crawl under the bed and I’d freeze and wait for him to come out, but then I’d hear him like right next to me on the wall and it was awful. I was so determined to kill him and that black centipede.I tried throwing stuff at them, but they’d wriggle away. After a while of throwing lots of stuff at them, they both crawled into my suitcase.Which really freaked me out!!I could hear them breathing in the suitcase and that creepy huge caterpillar making wheezy squeaks. So then I went upstairs to get my aunt who came down with me. She basically shoved her arms into the suitcase and I was like, WAIT THEY’RE RIGHT THERE! RIGHT next to her arm, but they were under like a notebook.She was like ah! and yanked her arms out. Then she slowly lifted the notebook and they were laying there breathing heavily but otherwise staying very still.Then she got some lotion and hairspray out and first sprayed the big caterpillar with it, which made his skin deteriorate, and sizzled the fur off, so his back was sort of see-through and thin. Then she like pierced his back with the nozzle of the lotion and filled his body up with it.When he breathed in, the lotion would sink into this purple liquid in his body, and then when he breathed out the lotion would expand.And he kept doing that till he burst at the seamsThen my aunt covered him in paper towels and was walking away with him but I never saw how she got rid of the centipede (if she did) or where she went with the creepy-ass caterpillar because I woke up.
“cuya cadena de glucosa se consigue romper con unas encimas” … encimas, ¿o debajas?
Llámelo encima o enzima, al final lo has entendido, ¿cierto? :P
Gracias por la corrección sarcástica.
De nada, hombre. Por cierto, has dejado los pequeños trozos de cartón del pequeño contenedor sin pequeñas tildes.
