Besoeker,
£1.25 million is the basic cost of the wind turbine, after a bit of research I discovered that all the costs involved to install an off shore Turbine is in the region of £1 million and after it’s lifetime of 20 to 25 years it will be another £500,000 to de-commission it at todays prices, so probably about £3 to £5 million in 20 to 25 years time. Another cost involved is the annual rental cost of the land they are sited on, on land farmers are receiving about £40,000 a year for each Wind Turbine, as for those off shore if it is the same £40,000 per annum for each Wind Turbine.
As most beaches and seabeds out to 12 nautical miles in the UK are Crown Property then that income must be going to the Royal Family.
I still have not been able to find out about certain names that I am sure are involved in ownership and investment of the Wind Turbines.
Yes but nothing like the Severn Estuary scheme. And then there is the problem at slack water. How do you manage that? .
I’m not pro hydro schemes for power. As it happens I designed a few such systems. One in Fife was the largest. It was originally used for a mill race and later it was used to power in the paper mill. That was 500kW. Just to get an idea of scale the whole mill was 5,000 kW.
Besoeker,
I can see what you mean about slack water in the Estuary, but that shouldn’t be such a problem with off shore Turbines further out to sea.
As you say you are not pro hydro schemes, when obviously I am (and probably an advocate for "many of the old ways were better than the new and why change for the sake of change) but it is great to learn things from someone the other side of the fence so to speak and it is great that we have both been polite and considerate to each others stance when so many others could have developed it into a slagging match.
Oops - I was in a rush and I made an error! I AM pro hydro schemes. I have engineered a few but not quite on the scale of The Three Gorges Dam !!
Would I be wrong in thinking that batteries have been made in the past using saline and Zinc, or carbon…Wouldn’t it be grand if we could build perpetual batteries using sea water. No moving parts and an endless supply of power.
Wiki says:-
Salt water battery
Description
A saltwater battery is a type of battery that uses a mixture of salt and water as its electrolyte. Unlike traditional batteries, saltwater batteries are safer to use because they are non-flammable and environmental friendly. This makes them to be an eco-friendly energy storage solutions. Wikipedia
A good idea. But 460 Wh is not a lot. A typical UK residence is 10,000 Wh per day.
