NTT will let for sale the system in May this year first only in Japan for approximately 190 USD, and in near future in the rest of the world.
Greeting. I'm from the future. 2015. This is old tech made in 2004. But got popular only last year(2014). Lol.
I already made one for myself with just an lipo and solarpanel and a regulator
how come they aren't using this technology now in new phones like iphone nokia 5800 or idou????
