I'm not a technician, but I know that I now get 12MBps (via DSL) and they haven't exchanged the phone lines. So they must have come up with something.

- ori_b 14y agoThe physical copper wire is still the same, but you're no longer talking to the phone system on the other end of it, as I understand it. DSL is no longer using the "phone line". It's just using the phone cable. The battery analogy would be creating a fuel cell in a AA (or whatever) form factor. It circumvents the limits on battery technology by not being a battery, in spite of plugging into the same physical slot. (NB: I am not a DSL technician, I could be wrong).
- Tichy 14y agoMaybe, but the point is the constraint was never "use the phone system", only to use the cable.
- ori_b 14y agoThat's not the takeaway I got. What I got is that the (communication endpoint,fundamental energy storage) technology has to change before there can be large improvements in (network speed, energy storage capacity).
- Tichy 14y agoSure, but that article seems to make some assumptions about batteries that might be irrelevant. The requirement is not "a battery has to power the car", it is just "a clean energy source has to power an electric motor".
