Barney,
Pardon me for saying this, but your analogy is pretty wrong. An electrician is nothing more then an installer and trouble-shooter. In the long run, I'm no different then the guy who installed your carpets or unplugged your toilet.
However, I have to bring up some other facts.
First off, Franklin, Edison and Marconi weren't electricians either, they were inventors, and if you want to go a step further, Franklin really didn't invent Electricity, it has been there since the beginning of time and maybe even before that.
(Dealing with atoms and other pertinent electrons breaking valance shells, etc. Let me know if I'm boring you yet.)
Marconi invented the radio, yes, only after much help from others who taught him the theories of electricity. He explained this many times over when he was not given credit for desigining the device early on.
Now brace yourself for a shock.
Thomas Alva Edison may go down as one of the greatest con artists of all-time. He really wasn't so much the inventor as he was a businessman. He utilized people to invent for him by putting them on staff. (Doesn't this sound ironically like Rees Jones, Tom Fazio, Ed Seay, Jack Nicklaus and way too many others way too numerous to count?)
One of these staff members was a gentleman who is without doubt in my mind the man who took electrcity and developed a proper use for it. He knew more, figured out more, and even had more then unbelievable plans to change the world as we know it. Unfortunately, thanks to millionaire industrialist, James Pierpoint Morgan, (The industrialist, not the famed doctor from the great state of Indiana ) saw exactly what it all meant....
FREE ELECTRICITY
For a person of Morgan's business acumen, that just wouldn't do.
This genius's name?
Nikola Tesla
Please remember that name. He is a legend not unlike Old Tom Morris, Bill Kittleman, AW Tillinghast, CB MacDonald, Alister MacKenzie or Donald Ross.
You can thank him for discovering alternating current, radio control, three phase-electricity, power generation and transmission and many other things too far numerous to mention. He was one of the greatest genius' the world has ever known, and Edison went out of his way to not only destory him, but all of his ideas. (More Fazio and Rees?)
After many disagreements over the "positives and negatives" of alternating current vs. direct current, Tesla left Edison's employ and went to work for Charles Westinghouse who knew that Tesla was a genius and wanted to see him succeed. Together they brought alternating current to the world, first at the 1908 world's fair in St. Louis, where they succefully received the contract to light-up the fair at night, (using alternating current.) and then eventually succeeded in winning the contract to build the first power generating station in Niagara Falls, NY.
Edison, a pretty arrogant individual decided to go out of his way to show how dangerous AC current was by electrocuting elephants and dogs, showing how dangeous the stuff is. (A truth) However, the cost to utilize direct current, even today would require power generating substations less then a 1000' feet from your home, combined with voltage drop from those distances. (In other words, some houses would be brighter lit then others.) Guess who owned this patent?
(Thomas Edison)
Common sense eventually prevailed with Edison and he bought the rights to Westinghouse's patent, which was invented by Tesla.
So, in ending, how do I know all of this? Unlike messers Fazio, Jones, and Pascuzzo, I have gone out of my way to learn it and give the person who revolultionized it, his due.
I have also learned that while electrical construction is far advanced today then it was in the old days of the youth of refineable electrical power, the process and theories have not changed. When I read of the works of Nikola Tesla, I get excited to learn more. Its not boring like the instructional manual of a programmable logic controller that simplifies electrical theory. All of that equipment costs a lot of money, and while it may save time as far as installation, in the end, the old stuff works the same at a much less cost.
It is minimal.
