New power lines and pylons

[FonterraFarmer]

" Dad,he recons powerlines are a reminder of mans ability to generate electricity!"

 

[GTB]

well i can assure you there is plenty of water here

But not enough fall in most cases. You'd be amazed how much fall is needed to make a water turbine viable and when there is enough fall there's usually not enough water. Very rarely do the two combine.

Google Hoover , Victoria falls, Igauzou etc. Dams to see what you need to make realistic Hydro power.
Lake Mead feeding the Hoover Dam is about 64,000 Ha.

 

[Will Blackburn]

Why can't existing dams be converted to hydro all that wasted energy when the water flows to Liverpool or Birmingham?

There must be less than 2m fall between Manchester and Liverpool. Tidal is the way forward, but the RSPB take issue with that.

If you have one cubic foot per second of flow and a drop of 18 feet, then you have the potential to generate a kilowatt.
Some of the regulating reservoirs in Wales do generate power. Llyn Celyn near Bala and I think Clywedog further South. There will be others that I don't know about.
A lot of sites were abandoned and destroyed when the governments new water act setting up the Welsh Water Development Authority and its sisters, set fees for abstracting all water at ruinous rates for anyone who was generating.
Anyone who has an irrigation abstraction licence care to calculate how much I would have to pay on my usage of 2.2 cubic metres per second day and night?

By my reckoning that is about £15,000 per annum
This figure does not take into account any seasonal variations or in fact differences between the different uses it may be put to

There is a vastly different charge if you return the water to the water course as opposed to spray irrigation, you may have taken that into account?

 

[Exfarmer]

No, this figure was the only one I could find off the EA tables for Welsh abstraction.

i detest nimbys with a passion they are the lowest form of life on the planet.

Nimbys are fine everywhere except round here

 

[Kevtherev]

What about dinorwig power station at llanberis? That's a hydro been there years.

 

[Exfarmer]

Is that the pumped station

When Dr Beeching was closing the railways there were outcries and large public meetings in the towns involved. The first question from the speaker was - How many of you have traveled to this meeting by car? 95% of his audience that were there to complain about the proposed loss of the trains would raise their hands.

We had a similar issue when there was a scare about mobile phone masts. Protest meetings where people were asked to sign up with their name and mobile number. 100%

We have an ongoing issue locally about pylons. If I look out of my bedroom window I can see two rows of pylons and two television relay masts; I wish they weren't there but I do like the lights coming on when I turn the switch, and watching crap on the telly on a quiet evening.

These pylons were put up in the early 1960's and there are a big set and a little set, they want to take the little set down and put up a bigger set thereby increasing the spaces between the pylons. I can see that this would be a pain for people living under the wires, as some would be winners and some would be looses, depending on whether the pylons ended up nearer or further away.

Most of our protesters, including some minor celebs and a few London journalists who have relocated, live several miles from the pylons but worry that they can see them as they drive about. My thoroughly unscientific survey says that aprox 95-98% of the people complaining bought their houses after the pylons were built. They all want the cables buried and they all what compensation for the loss of value to their property(????)

great post

Does that mean there are different charges depending on what water is used for?
15k would be very roughly what my FIT payment would be if my set qualified. It doesn't, because my father took the long view about elec. prices and ordered it when the unit price passed 2p. I would have to scrap it and install new in order to qualify.

You can get useful amounts of electric out of a Vortex turbine with as little as 0.7 mtr head. A 10kw machine requires a 1.7mtr head and 1 m3 per second flow and would be a similar cost to a 10kw wind turbine.

Why do all these environmental types find littering our countryside with wind turbines and new pylons preferable to a few nuclear power stations? I genuinely don't think it makes any sense at all. Either from a climate change perspective, a local environment perspective or an energy supply perspective. I really can't get my head around it!!

Try asking the same question on a Japanese farming forum.

An old reactor based on 50's/60's technology is hit by a tsunami it was never designed to withstand. Despite this there's no nuclear explosion, no deaths attributable to radiation and outside of the plant itself radiation levels are safe. Bloody good advert for nuclear I'd have thought. I heard that around 1500 deaths were caused by the evacuation though.

Looking at your forum name @renewablejohn I'm guessing you maybe have an interest in promoting renewables?
