That gear dated back to the 1940-50s (it was 1968 at the time). It wasn't broadband though. -- Your character is your destiny. |

What we're working on is actually through water. |

Not waves bouncing through, but information travelling through.
Best part - testing shows it can work without pipes. |

 mc5w join:2002-06-14 Independence, OH | Metal underground gas lines have an insulating coating in order to make cathodic corrosion work better. This way, the direct current electric field is concentrated at the surface of the pipe where it is needed the most. The insulation cuts down on the current needed so that the current only needs to flow where there is a chink in the insulation.
Similarly, plastic gas lines have an insulated wire both so that they can be traced and so that cathodic protection current can reach isolated metal pipe sections.
What this technology does is to put a carrier signal for the broadband on top of the cathodic protection voltage. This is not that much different than how CATV has 48 volts nominal, 60 volts DC maximum to power the amplifiers and the fiber to coax boxes. Some of the CATV power supply boxes that I have seen have a 48 volt battery bank inside to ride out short term power failures. The voltage required to fully charge a 48 battery is 60 volts, 65 volts to fast charge. The radio frequency cable TV and DOCSIS signals coexist with the 48 volts.
However, most natural gas services have a dielectric union ( usually in the meter bar ) to keep the cathodic protection current from going into the furnace and flowing through the equipment ground for the service. This means that the broadband signal would have to be tapped on the supply side of the meter.
Also, Dominion East Ohio Gas would never go for this as they are paranoid about safety. The reason why is that during World War 2 the War Materials Board made East Ohio Gas build 2 liquified natural gas tanks out of substandard thickness steel and insulation. Eventually, both tanks ruptured and burned down a whole neighborhood. The sewer system turned into a giant flamethrower. If you want your gasfitting job to pass inspection, do not mention this incident to the inspector from Dominio East Ohio Gas. They are still sore about it. |

 | reply to Derfel Derfel is going to rename a local lake 'Lake LAN'! lol
What will the encription be?
