Brilliant. To today - Edison Lost The War Of Currents, But DC Networks Are Now Making A Big Comeback
Aug 26, 2018 by Tomas Kellner
When Thomas Edison opened the world’s first central power plant on Pearl Street in downtown Manhattan in 1882, he revolutionized how people used electricity. Until then, most users generated their own power. Edison, however, used a network of cables running under New York streets to carry electricity to homes and businesses from a remote generator. This design, which seems like common sense today, was revolutionary back then.
Edison used direct current, or DC, to distribute power. But when he tried to send electricity for distances longer than a mile, his network started losing voltage. Edison’s rivals George Westinghouse and Nikola Tesla pounced on the shortcoming, and their system transforming and transmitting alternating current, or AC, has since become the norm all over the world.
But DC has never gone away. In fact, it has been staging a quiet comeback as an efficient way to transmit power from remote locations like offshore wind farms or zip it long distance across large states like Texas, and possibly even the entire United States. IEEE Spectrum recently reported that the latest incarnation of DC transmission — high-voltage direct current, or HVDC — was “readily available and increasingly affordable, and could replace the old equipment to make long-distance electric power transfers between the eastern and western United States possible.” Some of the HVDC lines could be buried along existing railroad rights-of-way to quicken the installation process.
We talked to GE Power’s HVDC expert Rafael Bonchang about the technology’s latest applications. Here’s an edited version of our conversation.

While some quotes whither to irrelevance over time, some grow in sparkle. The one of Nikola Tesla's
""When wireless is perfectly applied the whole earth will be converted into a huge brain, which in fact it is, all things being particles of a real and rhythmic whole. We shall be able to communicate with one another instantly, irrespective of distance. Not only this, but through television and telephony we shall see and hear one another as perfectly as though we were face to face, despite intervening distances of thousands of miles; and the instruments through which we shall be able to do his will be amazingly simple compared with our present telephone. A man will be able to carry one in his vest pocket." – Nikola Tesla 1926"
of yours is one of the latter. To be corny it's brilliance is electric.
One earlier Tesla quote
"If we use our fuel to get our power, we are living on our capital and exhausting it rapidly. This method is barbarous and wantonly wasteful, and will have to be stopped in the interest of coming generations. The heat of the sun's rays represents an immense amount of energy vastly in excess of waterpower ... The sun's energy controlled to create lakes and rivers for motive purposes and transformation of arid deserts into fertile land..."

Also there a birthday greeting, July 10, 2014
and totally unrelated, Happy Birthday to Nikola Tesla.

Brilliant. DesertDrifter, Thanks for bringing Nikola Tesla's genius back to today.
