8 miles. Not something done overnight and required towers to reach the upper parts of the 'canvas'
indicating the people had the tech to make rope/cordage, cut and lash towers and the organization to do the painting....

The "Ram Pump" is still used today.
It is a method of pumping water without the use of an external power source.
There are some demonstrated on you tube and older ones still in service in the Philippines.
For fun I made one my self and it really works.

 

Been wanting to make a ram pump myself,, was wondering if I could get the water flow to spin an alternator, or washer motor at an rpm enough to charge batteries. Just haven't had time to get started on it.

 

Do a site search for "hydraulic ram pump" posted by Aisa Off Grid a few years ago. There are two pdfs related to the construction and limitations of those devices.

 

Thank you ,,, wiil do ,, I spoke with Asia off Grid a few times,, really nice guy ,, I was really shocked by his passing. Thanks again.
