Connection and Innovation

Linking Lake Erie via the Hudson River to New York City, the Erie Canal changed the economy of the United States. Internal waterways have stimulated advances in culture and exchange dating back to China’s Grand Canal. Many jobs were created; workers flocked to construction sites along the route. They lived together in camps, developing team organizational skills that would characterize American business. Innovation flourished; Erie saw the first hydraulic cement used in the United States. Open for business in 1825, the waterway was an instant success. Before it cost $100 per ton to transport goods over land; now, $10 per ton. A museum dedicated to the Erie Canal is housed in the only existing weighlock building in the United States (http://eriecanalmuseum.org). The Erie Canal could be called the Internet of its day: both were connection routes financed by government but developed by the private sector. Entrepreneurial ventures sprang up, soon exceeding initial cost of building the route. How does connection stimulate innovation? What’s beyond the Internet?

Chambered Locks

Posted on by zoequinn001

Chambered locks area a common feature on canals around the world. The first one, however, was located on the Grand Canal in China, dating back to 983 A.D. A lock is a mechanism for moving a boat or ship up or down an elevated portion of a river. The boat enters the first chamber of the lock, which is sealed by watertight gates at either end. The water level then rises or falls to the level of the second chamber, depending on the direction the boat is trying to go: upriver, the  chamber fills; downriver, the chamber empties. Once the desired level is reached, the gate in front of the boat opens and the process is repeated. Below is an image of a modern lock from the lower elevation.
