Yes, after you insult their country, it's always impressive to get their name wrong.
Perhaps someone will correct me on this, but my understanding of the Tesla coil is that it is the electrical equivalent of the playground swing.
These aren't "illegal" lines, merely undocumented lines.
Wrong, these devices tap the lines by transformer action, at a different voltage, they need a different (in this case smaller) number of turns. I have even heard of people putting these sapping transformers in bird houses and raising them near the power line. They don't need to be touching. Oh, and changing the voltage on the line requires re-engineering of every transformer the utility provides and they should look at the size of the insulators on every pole, very expensive.
Good plan, but no plan is perfect, and many of the paying customers would also not get the message. A 50% increase may not be enough either, lots of equipment could be built to handle this.
A better plan would be to put regulators on all paying customers lines and then you could do your high voltage burn on the illegals, but the regulators are expensive and it may be easier to just pay some other poor people to cut the wires.
American Anti-gravity has an ongoing project to create "lifters". The book has detailed construction information. For brevity, you can see the web site and MPEG videos of test flights here.
This is a lifter in flight. The power is fed to the corona wire on the top of the triangle. There are thread tethers below to keep it from flying out of the box. The lifter is just some balsa wood sticks, aluminum foil and some 30 gauge magnet wire for the corona wire. Power input is 30,000 VDC at 1 mA.
Which is why I was truly only kidding. I know no plan like that could ever be implemented without the power company exposing themselves up to vast liabilities.
Still, it would be satisfying, if only in the short term.
LOL! You're probably right...sigh..
Then why do they take them down?
I think you missed my ironic commentary on "illegal" vs. "undocumented" immigrants.
Regarding the backward state of Mexico.
I think it is because the Mexican government discourages and sometimes outright forbids the importation of technology that would get them out of the stone ages.
Something about the theory of keeping the masses busy so they will not have the time or energy to rise up and overthrow the status quo.... And let the excess migrate elsewhere!!!
Ah... I follow.
Thanks for the link.
Very interesting subject
It is always nice to think that once in a while justice prevails. lol
"I love the smell of burning resistors in the morning....It smells like....Justice!"
I like Tupperville's commercial for winn dixie too (in Auburn country), but the smell of overheat in an electronics circuit is ladden with too many bad memories for me. (And a lot of the time my fault!) *sighing* Take care Sam, FRegards.
Tesla coils work through the 'magic' of tuned 'tank' circuits - what we call in the trade a "tuned tank (LC) circuit"
LC (Inductor and Capacitor) or 'tank' (resonant circuits) have the ability to store energy, alternately between the magnetic field in the coil and then alternately in the electric field in the capacitor.
Excitation of the secondary 'resonant' tank is done via the un-tuned, low voltage, high current primary; the primary and the secondary are coupled via a magnetic field (magnetic flux).
High voltages are developed via this mechanism: a slow-moving voltage source is applied to the primary, the current builds up in the primary - and then is interrupted, this creates a 'step' current function containing MUCH high frequency energy which is 'captured' by the secondary winding which is linked to the primary magnetically; high voltage is produced according to the well known equation:
e (in volts) = L (in Henrys) * di (the change in current in Amperes) / dt (the change in time in seconds)
di e = L * ---- dt
How about this elevator controller. That's a 40HP motor I'm leaning on, with open cable sheaves, etc. Notice the dates on the control drawing.Looks like the controller board and motor up at Tanglewood Resort (up on Lake Texoma) elevator ...
I don't suppose Tesla coils have practical applications. (?)Aside from easily generating high voltages easily - the principles incorprated in a Teslas coil are embodied in every day items -
- in that tuned circuits where primary and secondaries are linked by magnetic flux/a magnetic field are incorporated in everyday AM and FM broadcast radios and their transmitters to automotive (spark) ignition systems (even though the secondaries of the coild are *not* strictly tuned, they do 'ring' owing to the stray interwire capacitance that exists in any physcial coil).
This one is in a building on Maple St. near downtown Dallas.
