Electricidad wireless

Si hay algo que haga falta hoy en día para muchísimos ámbitos de nuestra vida cotidiana es una batería: móviles, cámaras de fotos, máquinas de afeitar, mandos de consola, reproductores de mp3, PDA, portátiles, linternas, GPS,…

Desde hace años se trabaja en hacer más eficientes dichas baterías. Más pequeñas y de mayor duración. Pero en el MIT parecen pensar que no es suficiente, así que han optado por investigar la forma de conseguir transmitir electricidad sin cables.

De momento el resultado más positivo les ha permitido mantener encendida una bombilla de 60 watios durante una hora a dos metros de distancia. Que no es un mal paso para comenzar.

El equipo interdisciplinar de investigación ha conseguido este éxito haciendo resonar emisor y receptor eléctrico con un mismo campo magnético.

A mi personalmente este tema me da un poco de respingo, aunque supongo que los prejuicios terminan pasandose con el tiempo. Veremos si esta vía de investigación llega a algun lado.
