El último cable: una (no tan) prosaica innovación - contra la antitipia :-)

La entrada es de The Economist y refiere a los esfuerzos por "liberar" al teléfono móvil (e inalámbrico) del cable que le lleva, desde la toma de la pared o el carro, a través del cargador, la energía que recarga sus baterías; liberación que nos alcanzaría de una vez también a los usuarios; loables esfuerzos ¿alguien diría que no?

Extracto, el camino se ha visto:

"IF THE father of electromagnetism, Michael Faraday, could be transported into the 21st century, he would no doubt be awestruck by the iPhone. After five hours of tapping its touch-screen to browse the internet, make calls, play games and determine his location via satellite-positioning, he might also find himself a little puzzled. Why, with all the advances in technology and communications, would such a sophisticated device still need to be plugged in to be recharged?..."

Pero aunque la ciencia las tenga "claras", la tecnología no "alumbra" así no más, sin parto...

Extracto, el camino no se ha caminado del todo:

"To seasoned observers of the electronics industry, the promise of wireless recharging sounds depressingly familiar. In 2004 Splashpower, a British technology firm, was citing “very strong” interest from consumer-electronics firms for its wireless charging pad. Based on the principle of electromagnetic induction that Faraday had discovered in the 19th century, the company’s “Splashpad” contained a coil that generated a magnetic field when a current flowed through it. When a mobile device containing a corresponding coil was brought near the pad, the process was reversed as the magnetic field generated a current in the second coil, charging the device’s battery without the use of wires. Unfortunately, although Faraday’s principles of electromagnetic induction have stood the test of time, Splashpower has not—it was declared bankrupt last year without having launched a single product..."

El cable es un estorbo pues con varios cables es inevitable el enredo; enredo que se explica, si se quiere explicar, por la "ley" de la antitipia: dos o más cuerpos no pueden ocupar el mismo lugar al mismo tiempo :-)
