A WALK THROUGH SAN FRANCISCO 100 YEARS AGO

THIS UNIQUE NEWSLETTER HAS PRESERVED THE TIME, LIFE AND SPIRIT OF A CENTURY AGO TO OUR DAYS. AT THAT TIME IN AMERICA (SAN FRANCISCO) THERE WAS A MIRACLE TECHNOLOGY WORKING THAT SURPRISED THE WHOLE CIVILIZED WORLD WITH ITS HIGHEST TECHNOLOGY FOR THAT TIME. IT WAS A TRAM WITHOUT THE USUAL ELECTRIC WIRE. THE DRIVE FOR IT WAS AN UNDERGROUND CABLE TO WHICH THE TRAM CAR WAS ATTACHED USING A METAL CLAMP. WHEN THE CLAMP WAS LOOSEN, THE TRAM STOPED, AND THE CABLE CONTINUED ITS MOVEMENT, WINDING ON THE DRUM AT THE END STATION. THIS GENIUS, FROM THE POINT OF POINT OF TECHNICAL SOLUTION, ENGINEERING DEVICE WAS ELEMENTARY AND SIMPLE, LIKE EVERYTHING GENIUS! SUCH TRAMS HAVE BEEN PRESERVED IN SAN FRANCISCO TO THIS DAY AND STILL AMAZE VISITING TOURISTS WITH THEIR “HIGH TECHNICAL PROGRESS” IN THE AGE OF ELECTRONICS AND SPACE TECHNOLOGY.
