Obviously not everywhere has flowing water and even where there is, it not provide enough power for practical use. The amount of power that can be provided by a stream depends on to two things. These are called the head and the flow. The head (measured in metres(m)) is the vertical drop from the top of system (where the water enters your pipe/penstock) to the bottom (where it is released). Head should not be confused with the distance between the top and bottom of the system (which should be kept to a minimum). It is the difference in height, the drop, that counts.

Photo: Watercone Passive Solar One Step Water Condensation FTW! We wrote about the Watercone back in 2004 , but considering how much TreeHugger's audience has grown since then, it's likely that only a handful of you were reading the site back then. I think it's time to have a second look at this very clever device that has the potential to help provide clean drinking water for millions of people who are lacking access to clean water (or if they do, maybe the access is intermittent and they could use a plan B).
This information is provided as a service to those wanting to try to build their own hydraulic ram pump. The data from our experiences with one of these home-made hydraulic ram pumps is listed in Table 4 near the bottom of this document. The typical cost of fittings for an 1-1/4" pump is currently $120.00 (U.S.A.) regardless of whether galvanized or PVC fittings are used. Table 1. Image Key All connectors between the fittings are threaded pipe nipples - usually 2" long or shorter.
Canyon Hydro has developed this Guide to Hydropower to help you gain a basic understanding of how "home power" micro-hydro systems work, and what goes into the design. We’ve tried to keep the content objective and hype-free, so you won’t see information about specific Canyon Hydro systems. (But we do hope you keep us in mind when you’re ready to build your hydro system.) If you’re just starting out, we think you will find this information extremely helpful. If you’re already a senior hydro engineer, you may be more interested in Canyon’s Utility/IPP Systems .
