Posted: 28/11/2011 22:44:34 Reply | Quote I recall that Pelton Wheels are very efficient and seeing some in industrial use with a snail-like cast iron inlet manifold and multiple jets with exhausted water discharged axially. I think that the mine at Laxey on the IOM had a few Mac Adam Fourneyron turbines to work compressors etc towards the end of its life. Any ideas about power outputs and head of water required? Wilkpedia gives the basic formulae, but somebody must have produced a nomograph or spreadsheet at some point. http://en.wikipedia.org/wiki/Pelton_wheel I live in an area with deep valleys around Stroud with plenty of small steams and rivers. We are always trying to fend off the wind turbine brigade from erecting any more of those horrors. What could be simpler than set up a few of these little beauties instead. Water would be returned to the river and could be used lower down. The Frome had a number of water mills on its route in the old days. By the way, does anybody know whether hydraulic rams were ever use for pumping in mines - there are lots of them round here but they work to a relatively low head. Hydraulic rams have only two moving parts, a spring or weight loaded waste valve (the clack valve) and a delivery check valve making them cheap to build, easy to maintain, and very reliable. In addition, there is a drive pipe supplying water from an elevated source, and a delivery pipe, taking a portion of the water that comes through the drive pipe to an elevation higher than the source.

Posted: 29/11/2011 08:21:37 Reply | Quote Roger, stop and think for a moment and you will realise that you can't use a ram pump to drain water. It has no ability to suck, it only pumps a proportion of it's own feed water. So the mine would fill up quicker than the ram can pump! IP: 95.148.25.206 |

Posted: 29/11/2011 10:04:53 Reply | Quote Oakeley used an injector -as (if I remember correctly) so did Rhosydd. The Oakeley one was on floor H, supplied with water via a pipe from Llyn Iwerddon down the old vertical balance shaft. The injector lifted only the one floor from H up to G - the main drainage level at 1200gpm. Grahami -- The map is the territory - especially in chain scale. IP: 212.219.117.103 |

Water would be returned to the river and could be used lower down. Sorry to pour cold water (dreadful pun!) on your aspiration but unless things have changed since my time with a river authority - admittedly 25 years ago - you'll be charged for abstracting water to generate electricity. So you'd have to factor in the cost of the abstraction licence into your cost benefit analysis of your proposed installation. Given the trend in energy prices however, it should still be financially attractive if you can install a pelton wheel or turbine (turbines are more efficient than pelton wheels) large enough to generate all or most of your needs. Do post to let aditnow members know how you get on! IP: 92.26.78.190 Edited: 29/11/2011 18:39:44 by Graigfawr |

You could claim ROCs though which can be a very lucrative way of "generating" some income. No pun intended...  -- O'r graig, egni. |

Posted: 30/11/2011 10:53:20 Reply | Quote Graigfawr – you are probably quite right of course. It couldn't be that simple in this country! But I don’t see why you couldn’t get together a co-operative of landowners and other interested groups and it would not be impossible, I think, get an Act of Parliament to form something like “The Stroud Hydro-Power Company” etc. It is interesting to think that Water Authorities have monopoly rights over water power – effectively privatising gravity! With a certain amount of Parliamentary Hurrumphing, I suppose you might argue that hydro power should be put on the same competitive level with wind….. IP: 212.139.241.222 |
