I just came across this site: http://www.engwonders.byethost9.com/pindex.html
as a result of visiting the subject of the next article.
http://www.engwonders.byethost9.com/e034.html

A friend and I walked up to this rather interesting reservoir that had formed part of pumped storage system. In this case the power for pumping up to the reservoir 1000 feet above the river was totally derived from the flow at river level.

The reservoir was contained by a reinforced concrete square box, 192' x 192' x 15'.

Very interested article. What would have caused it demise?

I'm not sure. Perhaps the cost of electricity from the grid started to look more favourable than the maintenance costs of the of the generators and pumps. Perhaps leakage became a problem.

It's true that there are many pumped storage schemes and they generally draw power from the grid to pump water up to the reservoir. The reason being that power companies do not like large changes in load over the course of a day.

The thing that really impressed me about the Kirnie Hill scheme was that all its power for pumping was taken from the river 1000 ft below the reservoir. There was no connection to the grid.

Hi
I remember a TV programme about the Lakes-Manchester Aqueducts. http://www.engwonders.byethost9.com/e039.html

They are totally gravity fed and it struck me that it should now be possible to insert power turbines into the aqueducts in order to generate power as well as deliver water to Manchester.

Glasgow has a similar gravity fed water supply bringing water from Loch Katrine 40 odd miles away. Those Victorian engineers were definitely a breed apart.

Those Victorians looked a long back in history for their inspiration:

Back in the day, when "everyone" thought that wood-coal-oil would last for eons, renewable energy wasn't much of a discussion point at the pub.

Maybe the problem rests with the short term system of Government, for which I don't have an answer but it is my belief that trying to cure global warming by installing huge cooling fans is not the way forward. There are days when some of them are not even switched on ... Wink

We are an island, the tides come and go twice a day, tide tables are predictable for centuries, wind is not, neither is solar power. I have no idea why we do not use sea power more.

solar power is variable and wind power is more so. tidal power is if harnessed very powerful and relabel too.
however its mainly down to cost of development and maintenance for any underwater apparatus that seems to be stumbling block.
plus no tax relief etc .if we look at say thames barrier .it has water control sections that can be altered to set a given water flow rate ( or none ) an dis adjustable so flow height over each barrier can be set and. altered as tide height does.
assuming either sides of main 'free' flow section for ships/boats to cross barrier, were set up to contain and divert water ( funnel?) through a turbine then. free power. would be available twice a day for as long as equipment worked . possibly not enough generation though to make it worthwhile to a power company .. imagine though say a bank of such turbines set. across whole mouth of rivers around UK.. that may be worthwhile output !

Ignoring the cost.

High tide in (Example Blackpool) and Hi tide in (Example Cleethorpes) are 7 hours apart.
