Giant ‘telescope’ links London, New York – CNN.com

LONDON, England (CNN) — As the first splinters of sunlight spread their warmth on the south bank of the River Thames on Thursday, it became clear that after more than a century, the vision of Victorian engineer Alexander Stanhope St. George had finally been realized.

The Telectroscope lets Londoners and New Yorkers see each other in real time.

In all its optical brilliance and brass and wood, there stood the Telectroscope: an 11.2-meter-(37 feet) long by 3.3-meter-(11 feet) tall dream of a device allowing people on one side of the Atlantic to look into its person-size lens and, in real time, see those on the other side via a recently completed tunnel running under the ocean. (Think 19th-century Webcam. Or maybe Victorian-age video phone.)

And all the credit goes to British artist Paul St. George. If he had not been rummaging through great-grandpa Alexander’s personal effects a few years ago, the Telectroscope might still exist only on paper, hidden away deep inside some old box.

But fortunately, St. George could not bear that thought and thus decided he should be the one to finish what his great-grandfather had started. It was quite simply the right thing to do. Plus, it would make a pretty cool public art exhibit.
