You must not have read the article. LP has a distance maximum. It is meant for local (in-house) connections. Telecoms are already using fibre-optic connections and have been for years (due to scalablity: same fibre can trasmit as much as the back-end tech can deliver it. You WILL NOT be getting LP from your telecom. Not to mention servers have been and always will be the bottleneck. No matter how fast you hook-up, joe-shmoes website cannot push info down the pipe to millions of people that fast.
Dude, what?You realize that the US uses DC for most of it's long-distance transmission lines, right? I imagine your turbine doesn't kick out high enough voltages or something; DC transmission done right is very very good for very long distances. We use AC power because it was marketed better way way back in the day.
Anyway, back on topic, if this is to take off, I imagine that they will throw a copper pair in there for power needs. Constraining it to powered devices would only hinder its take-off as a do-all-end-all cable. Why exactly is it (copper) not economical? Copper is dirt cheap (for now, granted), glass for the fibre is relatively dirt cheap. There shouldn't be any reason why running the two together would be a problem. One is infrared optical, one is DC electrical. They should have no reason to interfere with one another.
What, what?
AC domenated becasue it was at the time the only cost effective way to up the voltages.
It wasnt untill the late '40s that the arc valves were reliable enough for the voltages required for DC long distance trasnmission,
