Micro-hydro and ram pumps

Other

Has anyone researched the availability and use of micro-hydro generators, and the (associated) use of ram pumps?
Many of us live on land with both permanent water courses and significant gradients. I often look at the water tumbling down our little creek and wonder how we could harness it.
Ram pumps are old technology largely discarded because of their low performance when compared with a fossil fuel powered pumps and, consequently, they are hard to find. To-date I have only found one "boutique" manufacturer in the US but they were once produced here in Australia. It's time for ram pumps to make a comeback.
As for micro-hydro, the systems I have seen so far are all homemade, based on reverse-engineered dynamos or the like. I have heard of "in-pipe" generators but cannot find them.
Please post a response if you have any useful info.

Hi Anonymous inquirer,

I don't have the information you seek, but I will forward your inquiry on to three local people who are knowldgeable about microhydro and most likely to be able to answer your question.

Questions such as your's don't always have a simple answer that fits into a sentence or two- there are lots of variables, and research is still in process.

If you could email me at elinwood@westnet.com.au, that would be easier than writing on this list - given that there doesn't seem to be any way of notification when a reply post is sent?? Or not that I can see.

Could post some reply to your question here though once received, so that others can learn something from your question.

What can you do during an online meeting? You can demonstrate new products to potential clients, share slideshows, collaborate with colleagues, or edit documents together. You can conduct online meetings with the same in-person features available to you as when you are holding the GoToMeeting presentation in front of a live audience. In a conference room, when comparing GoToMeeting vs DimDim, you might use a white board or chalkboard to demonstrate specific information. With GoToMeeting you use your computer to draw, highlight and point to items of interest on the screen.

I have read in an essay about RAM PUMPS. They are not advisable even they are inexpensive. The main reason for not advising it is because when it is used in prolonged time, it will mix with metal stain and could cause sickness to human.
