Hi,

Maybe the phone companies do not welcome the extra load on their lines if more and more people connect to them...   ;D

I don't know the law in the US, though I imagine it is not much different from Australia.

Here it is illegal to connect any device to the telephone network that has not been specifically approved.

Simple as that, apart of course from the theft of electricity.

Yes, I think its illegal everywhere,
Similarly stupid free_energy idea is to connect waterwheel(turbine) and generator in-line to City central water pipe line :o
As more customers (thousands!) use the water - as more energy you get,
This inventor had no idea that in principle it is stealing because water company uses pumps ...
Even you own this company - you will stole from yourself :'(
cheers,

This is hilarious!

I can imagine what happens when you draw too much current (it is monitored and limited by the TELCO).

You draw more current than normal telephone devices....
The electronics at the Telco list your line as possibly shorting or wet...
The Telco sends a technician to investigate - maybe more than one...
They start some distance from your home so it takes a bit of time to locate the problem....

They find the problem is in your house....

The labor, material, and test equipment usage fees appear on your next phone bill.

Current Telco systems in the US locate the problem without sending a technician. This isn't cheaper because they make you pay for the technology.

I'll bet the Telcos love these devices!

FCC equipment manufacturers are limited to 80uA (I think. It's been a while) during on-hook conditions.

Off-Hook current will be limited to the battery and loop. Published battery voltage is 48V (but usually around 55V) with an internal series resistance of 600 ohms.
While off-hook you will normally see around 20-40mA with a voltage of 8-12V depending on the loop.
Many systems will disconnect the current if the line shows inactivity for very long.

Ring cycles do not allow much.
Standard private line frequency is 20hz, 90vac, (with the same loop resistance and battery resistance) with a cadence of 2 seconds on 4 seconds off.
Some systems have frequencies ranging from 16hz to 66hz if they have not upgraded their ring generators since the party line days.

Take care.

Oh! Bummer if you have really tense muscles and you bought the Russian phone line powered vibrator.

I suppose these products may indicate why Chernobyl was such a disaster.

With the world economy the way it is expect to see other quality products pop up.

A far better power source is buy a 12V photo cell array from Habor Freight. Use it to maintain the charge on the car battery you borrowed from your Mother-in-Law's car.

I can imagine what happens when you draw too much current (it is monitored and limited by the TELCO).

You won't be drawing any real significant power, because all telephone systems use high impedance bridging circuits at the exchange point of connection. This protects the equipment at the exchange (and/or customers PABX) from inadvertant short circuits or other conditions such as "A leg" or "B leg" to earth faults on any copper pair or pairs.

Around the world telephony systems are mainly between 600 to 1000 ohms impedance (minimum/s) for copper pair connections. At 50volts DC this limits the maximum line current to a range from 83mA to 50mA. Even the AC ringer which is superimposed on the DC  (to ring your phone) which is usually between 75 volts - 90 volts experiences this high impedance restriction.

@hoptoad

Good information. The impedance is the key. I'm very familiar with the tech.

My local CO uses 5ESS switches. I've been in the building to see the nice battery bank used. The digital switches monitor many line parameters. A higher than normal current draw (even 10's of ma) will be logged and may trigger an automated maintenance ticket.

The power available is tiny but it is still theft.

LO....bloody L....


Like 50 bucks for a stinking local landline, laden with collusional and rapacious fees aint.


What the hell do you think the realization of free energy will be considered, if these robber baron utility hyenas will come after you for a stinking milliamp or two?


Brrrrr.....starting to feel a bit 'schilly' in here.....

@ SomedayIsle,

You are completely missing the point. It isn't about the few milliamps of stolen electricity. Telcoms are weary about any device being connected to their system that they haven't tested and approved. Incompatible devices can do great damage to the system. That is why unexpected drains on power are so closely monitored. It simply is an indicator that something is happening that shouldn't.

I don't think it is in anyone's interest to have the phone system collapse because some idiots are using phone powered Russian vibrators.

As well they should be....


Craaack!


Thank you 'sir' may we have another.
