Only on the west coast and in particular the Bristol channel and IIRC the bit between Ireland and Scotland is there any tidal flow worth capturing. By the time you get to the other side of the North sea, there is no tide left. Swedens shores are tideless and Denmarks are slight. the east coast of britain has much lower tides than the west |

To be honest, a few more major grid incidents like 2008, but slightly more severe to actually result in forced domestic load shedding (ie power cuts without warning) would change a few people's minds about nuclear power. Even the beardy tree shaggers, possibly. 2008 was close enough with emergency DCI (Demand Control Imminent) alerts being sent to the network operators. Wouldn't take a lot more to get to major power cuts. Sadly, National Grid seem to have hidden the system alerts webpage that used to be publically readable, so it's hard to know how much they are panicking in the future. If you want some good reading, google for National Grid Blackstart. At least they're prepared, But it's not an easy process to restart the grid if it all fell over which isn't entirely improbable. -- Tim Watts Hung parliament? Rather have a hanged parliament. |

I think you have missed the main point. As Bruce said tides follow a predictable cycle but what he missed is that tides at different places occur at different times. At any given time you can find tides round the coast at every possible state from high to low and ebb and flow. That's true. But it is the case that existing power stations are distributed around the country to meet regional demand. There are not huge transfers of power from one end of Britain to the other. The National Grid is there to serve regions by connecting regional power stations with their regional consumers. With tidal power you can't easily do that, other than covering the country with pylons to a far greater extent than exist today, and transmission losses become significant. There is also the issue that there are only a few sites where tidal power will be viable, if indeed it is viable at all. The idea that the entire coast would be suitable is fatuous in the extreme, because long stretches of the coastline have very low (near zero) tidal currents. So that takes us back to pumped storage, as I said before. which has similar drawbacks in that most demand is NOT at the bottom of a 1000 foot damn holding back a lake the size of loch ness, so you STILL need massive power cables connecting prime generators not just to customers but ALSO to pumped storage, and you STILL need AS MUCH pumped storage as generating capacity. So again, as with wind., you double up the costs. Of generating AND transmission, half of which is idle at any given time. I wonder which is the next blind alley the discussion will take? Photvoltaic, in which the whole sahara is covered with silicon panels that survive dust storms and camel attack, whilst massive terawatt cables snake under the mediterranean, untouched by Islamic terrorist hands, to emerge into a neon lit Europe, thus solving all our energy problems and a cost of only 50 times the gross national product, or 300 failed banks. |

It struck me as significant that it cost £6billion to build 60 miles from St Panc to Dover - this is a very crowded country. Also, when I once had to go Cambridge-Glasgow, it cost something like £60 on EasyJet and £300 by train. Given the huge subsidies for the trains, that hints to me that trains consume much more of society's resources to provide the same service, although I have no numbers here. Train prices vary wildly - a couple of weeks ago, I travelled from London KingsX to Inverness, in first class, for 52.80. (Standard would have been about 40.00, so I splurged.) Well I know a very hiugh up person iuna very large train company, and the way he explined it is this. "Franchises vary, as do subsidies. Train operator A has a franchise on a main line from London to the North. He paid a bloody lot for it, and so its not subsidised, its taxed. It gets commuter traffic, so its profitable and humongous ticket prices, BUT its the only train to get into London for 9 a.m. However operator B has a completely different franchise. He is operating a local service out of grimy Northern town on branch line C. He is subsidised to ensure that local train services exists. His trains, however, can escape onto the main line and go to london, 'as part of the local service' He charges almost nothing for the tickets, because he doesn't need to: He gets paid to run trains, not carry passengers' |

But if the Chapmans and Bloomfields of this world are to be believed, nuclear is so cheap that it needs no subsidy at all. So why aren't the companies who are poised to start building the next generation of nuclear power stations hard at work? Because the figures don't add up! I told you. Because there are no figures they can add up, when a huge part of the cost equation is an unknown *political* situation. EDF fully intends to build new stations on existing and new sites. It has planning permission, BUT it wont if it thinks a bunch of bearded lunatics are going to sit in the road, or that it will have to meet insane safety targets, or insane decomissioning targets. They are therefore demanding very hefty subsidies from the taxpayer before going ahead. No, they are not. Perhaps Messrs. Chapman and Bloomfield should go to these companies and tell them that their cost projections are completely wrong. Then Chapman and Bloomfield could set up as energy consultants and clean up ... as we know with nuclear waste, there's a lot of cleaning up to do! You know jack **** about nuclear power, or finance. |

"The Natural Philosopher" wrote in message ... But I believe we have the best chance with what we now have. I don't rate the LibDems much, but they carry 23% of the vote, and that gives the whole shebang more perceived legitimacy, No one won the election. All lost. Some lost less than others. Like those in mid-table at the end of the football season. They did not win the title, but never lost as they were not relegated. It is like Stoke City, Fulham and Sunderland arguing who was best in the league this season. Only a few points apart yet some scored more goals and some had better goal difference. Rather petty to argue about pedantic details in mid-table. Labour never lost in that they could have been in power if they wanted to - but at a price. The price to them was not worth it. The Tories were prepared to pay that price. In the sordid shameless dealings Labour won. The Tories did not implement fully what they wanted - they mainly represent the top 5-10% of the population and their gift to them, inheritance tax, was not delivered, as was many others. You could say they partially lost, but not by much. For 4 consecutive elections the Tories failed to get a majority. And they are in power. As Lord Faulkner said the Tories didn't give much away. The Lib Dems sold out on PR,which would have stopped the likes of the Tories getting in power again. |

More crap from an idiot. He has never heard of the Credit Crunch. He needs locking up. |

"Bruce" wrote in message ... So why aren't the companies who are poised to start building the next generation of nuclear power stations hard at work? Because the figures don't add up! Correct.. you don't spend millions on a project that needs but doesn't have government approval. You get approval first. Nothing will happen until the government decides to allow some to be built. Also remember that labour deliberately bankrupted the privatised British Energy and nobody was going to invest while labour was in charge. |

And who is building windmills with no subsidies? That's a fair point. But if the Chapmans and Bloomfields of this world are to be believed, nuclear is so cheap that it needs no subsidy at all. Bruce is sounding more and more like Dribble these days. |

To be honest, a few more major grid incidents like 2008, but slightly more severe to actually result in forced domestic load shedding (ie power cuts without warning) would change a few people's minds about nuclear power. Even the beardy tree shaggers, possibly. It appeared that the Government (the one that has just been kicked out) had no interest and no figures on how low wind power output actually gets when the weather conditions are unfavourable either from lack of wind or from too much wind and their only contingency plan for lack of power was to take industry off line. |

The marine environment is very challenging. Highly corrosive, teeming with life, very high loadings, unfriendly to workers. Great place to park a wind farm then. ;-) |

Butbutbut... The tides are not simultaneous. They vary from place to place (Southampton has twice as many as most other places as well) This should be enough to reduce the peaks/troughs. True, but the variation from north to south in Britain is only a few hours (can't recall the exact number). The more salient point is that not everywhere on the coast is a suitable turbine site. You need spots where tidal currents are very high. You need to put those nice people at: http://easytide.ukho.gov.uk/EASYTIDE...electPort.aspx right then. I started to extract the figures below to counter TMH's claim that there wasn't much range to our tides but here is as good a place as any to post them together, with times. Today's figures used. Time is GMT and range in metres. Place Range time East Coast Leith 4.4 8.20 River Tees 4.1 9.44 Grimsby 5.1 11.54 Hunstanton 5.5 13.12 Lowestoft 1.7 15.35 Harwich 3.3 17.33 Southend 4.8 18.55 West Coast Avonmouth 10.8 7.09 Aberdovey 4 8.11 Liverpool 7.4 11.02 Morecombe 7.5 11.25 Maryport 6.8 11.25 Times for the East Coast are for low water. Times for the West Coast are for high water. The grater the tidal range the greater the tidal flow or, in the case of tidal barrages the greater the potential. Tidal barrages have the potential to generate serious amounts of energy but the capital costs are enormous. Machines to tap tidal flow are I suppose on a par with wind turbines but should be cheaper to build and install as well as being more predictable. (In case it still isn't apparent to Bruce I am not a fan of windmills). |
