Putting Water to Work

#1 Post by Farside » Wed Dec 05, 2018 3:04 pm

The energy of moving water can be used to perform physical work, or harnessed to produce different forms of energy, like electricity in micro-hydro systems.

I started this topic to catalog and discuss different water based technologies that can be very useful in an off-grid situation.

This device is an interesting combination of two technologies:
1. The ram pump that uses water to pump water.
2. The trompe that uses water to compress air.

It appears that by combining these two technologies, the device can achieve a much higher air pressure with a much lower water head than is otherwise required, and the compressed air can be used for things like driving pneumatic tools, or for refrigeration.

Since I already referred to a water ram pump, here is a video on how they work and how to build one:

Since I also mentioned a trompe, here is a video of one in action.

In this case, it is used to aerate a fish pond without the need for any external energy source. But they can be used for any situation where a steady flow of air is required.
