      I don't think whoever wrote the blurb for the story RTFA on it being debunked last time.

      What was debunked is the idea that if you burn lots of money, break a few laws of physics, engineer electronic devices that can modulate information transmissions at rates orders of magnitude faster than the best we've got right now (but will cost under $60 apiece), and break a few more laws of physics, you can transmit data over the power grid in the exobit range. (That's thousands of gigabits.)

      Yeah, and it's in limited use in the US. It does require a fairly clean power system that doesn't mess up the imposed RF signal, including not "cleaning up" the power by filtering the RF signal out. And it requires that all your electronic gear have power supplies that do filter out the RF signal (or a device that does it that's plugged into the wall outlet). I've worked in a couple of development labs where we did exactly this. But these requirements pretty much rule it out for most commercial power systems.

      But the main evidence that the story was about a con job was the quote

      By piggybacking on this magnetic field, instead of on the electricity itself, he could obtain almost limitless speeds of transmission. [emphasis from the article]

      This clearly implies cluelessness. Now, you might not expect a manager type to understand what's wrong with this statement. But you'd expect that they'd have some EEs on their payroll, and an EE's basic reaction to such a statement would be to snicker and say "Yeah; right."

      Any manager who continues saying such things after a few minutes discussing it with their EEs is clearly involved in a con, and knows it. In his next con, he's gonna market a truck that doesn't damage the roads like other trucks do. His explanation will be that trucks do their damage by harming the base that the road is built on. But his trucks only drive on the surface of the road, so they won't damage the roadbed at all.

      (Hmmm ... Maybe I shouldn't suggest that. Someone will decide it's a good idea, take out a patent, and start marketing it ...)

      Yeah, you can transmit data by piggybacking it on power lines. But making it work on a legacy power system is gonna be expensive. Ripping out the system and building a new one would probably be cheaper in many (if not most) existing systems.

      In short it is possible, but using the relatively insensitive machines that were proposed once before, without changing the specs of the power currently being transferd, the signal would have to be so strong that the electricity grid would radiate excessively, And the proposed means of shielding that raditaion is so expensive so as not to be worth it.

      It CAN be donel. You do realize that your phone's run off of the electriicty supplied by the phone line (I.e. unless your phone has an answering machine it does not need to be plugged in.)

      There are 3 Barriers to doing it, and if we conquer ANY one of those barriers we can do it: [li]Use far more sensitive reading and writing mechanisms (or a dramitcally different method). [li]Use good RF shielding on the power lines [li]Change the power grid specs dramatically.

      While changing the shield or the power grid specs dramatically would require a massive revision of our powergrid, the first option is VERY likely to occure with the next 10 years, if it has not already happened, and will not be expensive or require masive upgrades.
