  1. Mennor, what you say is true but only half of the story. One part is that the wind farms are in the north but the power consumers (industry) are in the south and a vast programme of transmission line construction has started, at a huge cost, to connect the country directly. A lot of their power is currently (sorry) routed through neighbouring countries and it destabilises their grids. Wind energy in general is not a stable source of power particularly in variable wind speed conditiond. Without the inertia of thermal turbo alternators the system would not work. Also wind is not dispatchable , i.e. it does not cater for load increase or decrease, this balancing is done by thermal generation.. Unfortunately the general public is never informed of the very many real drawbacks of renewable generation and the real liability is that there are times where Europe is becalmed so virtually no wind power. This actually means that we need as much thermal generation capacity as peak grid demand meaning all the capacity of installed wind generation is wasted. No wonder Germany's electricity is so expensive, similarly as is ours. It is ludicrous that our government is planning to shut the few remaining British coal fired stations without any plan to replace that plant with new dispatchable plants. Not only that it leaves our grid at the mercy of gas supply and this is generally constricted during very cold weather, when peak electricity demand is greatest. We relied on coal to keep our grid functioning when the 'Beast from the East' hit the U.K.. That will surely occur again in the future. The relatively minute amount of CO2 from these stations is not a reason to shut them without adequate replacements. I believe it's a matter of when not if we have a major grid failure due to the inept policies of various energy ministers of our government. Because of this I have bought a diesel generator for our small business as insurance. Alec

    May's Brexit Plan

    Hello Rod, the thing to remember si that the E.U. has never been a democratic institution, it is a supranational one and run by selected officers. Alec

    Now there's lightening and lightening

    Hello RedRooster, " They could have left the washers off too " Many a true word said in jest. Colin Chapman saw a new mechanic to Team Lotus working on one of the cars and he ordered him to remove all the washers he had just fiited on whatever he was working on. Add lightness was one of Chapman's mottos. Alec

    May's Brexit Plan

    Hello all, I think there is some confusion here between Europe and the European Union, which is not a country at all but a ruling body over all member countries. Run by selected not elected people who wish to subvert all national aims of their members. The whole purpose of the European Union is control and not trade as we were told originally by Heath and endorsed with Wilson's referendum in 1975. It is proving to be very difficult to extract ourselves from this dictatorial body and will, no doubt take many years before we can start to really make headway again. We need a better class of politician if we are to make the most of our opportunities, as they have been out of practice for forty years or so as rubber stamp weilders of legislature. To compound it they seem to not only have passed into law the directives but gold plated them making them even worse. A classic example is the Climate Change Act, a law that is so detructive to the U.K. and yet all but 5 M.P.s voted for it. Alec

    Audi emissions group action

    Hello Paul, forgetting the very small amount of hydro, imagine two scenarios, no evs and evs. The grid load will be x with no evs and x + ev's , renewable genration cannot respond to load, you get what you get. With the + evs that extra load will be provided by more fossil fuel generation, in effect evs are fossil fuel powered. This is unlikely to change for decades and begs the question why are we expending large of amounts of money promoting them and adding extra infrastructure.

    Audi emissions group action

    Hello Nick, those will be relatively small given the total amount of electricity generated over the life of the station. Alec

    Audi emissions group action

    Hello Paul, was this research carri dout in France where most of their power is nuclear. In the U.K. electric cars will be fuelled by fossil fuelled generation which will alter the picture dramatically. Alec

    Differential pinion height

    Hello all, does anyone have the correct pinion setting height for a 3.45:1 saloon diferential. The workshop manual does not give this figure seimply detailing the setting tool which I do not have.. my Jaguar workshop manual gives this as 2.625" for a H4 Salisbury axle but I'm nor sure if the Triumph is the same because of differing ratios. Any advice or information as to where I can find the data? I can measure the existing pinion but would rather be able to double check to ensure the correct setting. Thanks. Alec

    Brake fluid cock-up

    Hello Nick, I'm no chemist so I heeded his advice? He did sort out the problem I had though. Incidentally I don't think the addition of methanol stops some people :-) Alec

    Brake fluid cock-up

    Paul, I had cause to speak to a Girling engineer about a problem, and flushing came up an I said the same " I know that the proper job is to empty the system, flush it with meths, " and his response was on no account use meths on brake systems as it is mineral oil based and will damage the seals. so I didn't. The silicone i use from Automec says on the package that it will mix with dot 4 type fluids but any advantage will be lost. Alec

    Home Power Generating

    Hello Mattius, the modular nuclear reactors gain on initial cost, or so it's claimed as they can be mass produced. The longer term down side is the staffing levels of say ten small plants versus one large plant. I can see their running costs being much higher? Incidentally, I worked at Trawsfynydd nuclear plant many years ago, long since shut down. Alec

    Home Power Generating

    Hello Motv8id, The Tesla battery (100 Megawatts) in South Australia state is good publicity but as a total answer to South Ausrtralia's many problems it is not. What is little publicised in the media is that South Australia has also bought 500 Megawatt of diesel generator back up. The battery will discharge completely in little over an hour, the diesels will provide, typically about 90% of capacity forever and a day. My interpratation is that the battery bridges the time lapse between the detection of a power shortfall and the diesels getting started and going online. Solar plus battery for grid independence, I'm sceptical but it depends on the loction? It certainly is a total non starter in the U.K, solar output now is pretty dismal. One factor that has upset the cost equation is the increased cost of grid supplied power simply due to the burden of renewable generation costs. Alec

    Camshaft Bearings

    Hello Roger, I have a Lister HR6 generator, but your one at 850 sounds wrong. For 50 Hz you should be at 750 rpm, assuming a four pole pair generator? Alec

    My weekend so far

    Hello Nick, another Daimler V8 was the 4.5 litre version of the 2.5 fitted to the Daimler Majestic Major saloon. Despite it's size it was very quick for it's day. I think William Lyons killed it off as it was a better and faster car than the Jaguar Mk 10. Alec
