Newsletter indexAnnual General Meeting Some 24 members and friends attended the AGM of the Society held at Taunton on 15th March. At the start of the meeting we remembered committee member, John Heath, who died in February (see obituary by John Haynes). Chairman David Hutton gave a summary of the activities over the last year and John Gale on behalf of the Treasurer presented the Society’s accounts. The following members were elected :-
This year it had been decided not to elect members to a South Sub-committee and instead to enrol members from the southern counties of Devon & Cornwall on the main committee. An EGM will be held later in the year to formalise this new arrangement. This is considered to be more effective than the sub-committee, which hasn’t been operating properly for some years. We are delighted that Keith Morgan and John Ferrier have agreed to serve on the main committee. We are grateful for the past services of Roger Christy, Geoff Setter and Ted Luscombe on the South Sub-committee. After the meeting Committee member, Marcus Palmen gave a talk entitled “My Boyhood Experiences in Europe during World War II” – see report elsewhere. Newsletter index Stop Press The proposal for the largest land based windfarm in Europe involving 181 turbines on the isle of Lewis, Outer Hebrides has been turned down by the Scottish Executive, since it would adversely affect the wildlife, which has considerable implications elsewhere. Newsletter indexEnergy Fund Did you know that there is a Government Marine Renewables Deployment Fund of £50M? The problem is that few can get their hands on the money because the conditions are too stringent. To comply, companies need to have full-scale devices operating in the sea, which leaves a lot of companies out in the cold. In contrast Portugal is offering a fixed premium price for electricity for 12 years – quite an incentive! Consequently only two applications to the fund have been received to date. Also there is the Carbon Trust, an independent company set up by Government to work with private and public sectors to reduce carbon emissions and to encourage new technologies, particularly energy efficient projects. Newsletter indexNuclear Debate The Economic Research Council (ERC) produced a report in March criticising the Government’s handling of the Nuclear building programme. They said that the Government appears to imagine that White Papers are going to motivate the private sector to build nuclear power stations, whereas it is financial incentives that are required. The Times stated that there are only three companies in Europe capable of building these stations, namely EDF, E-ON and RWE, who have the financial strength to make such a commitment. America has Westinghouse (owned by Toshiba) which is at present building four nuclear stations in China. Westinghouse is wanting to use Britain as a base for launching its nuclear credentials in Europe and is urging the Government to narrow its choice of reactor designs from four to two.
Severn Barrage In January Mr John Hutton Secretary of State for BERR announced that a new feasibility study would be undertaken of the proposed Severn Barrage scheme. Mr Hutton said the study will look at the range of options for power generation from the Severn Estuary tidal range, including barrages, lagoons and other technologies. He said "It will include a strategic environmental assessment of plans for generating electricity from the Severn Estuary tidal range to ensure a detailed understanding of its environmental resource, recognising the nature conservation significance of the estuary". Newsletter indexJohn Heath by John Haynes I was very sad to learn of the death of my old friend and colleague at the relatively early age of 70 years. I first met John at Mr H. Bearcroft’s Saturday morning classes for Student Engineers, Electricity House, Bristol in ’56. John Haynes

Annual Winter Luncheon This year’s Annual Winter Luncheon took place on Saturday 26th January on a fine if somewhat breezy day. Prior to the luncheon, some members and friends met in the morning at the North Somerset Museum hidden away in Burlington Street, a rather quiet backwater not too far from the hustle and bustle of Weston Super Mare’s High Street. After being welcomed by the staff, serving coffee and biscuits, we were given a potted history of the Museum before being left free to look around the many interesting exhibits. These cover the history of the local area over many centuries and of some of the prominent families. The growth of Weston as a seaside resort is well documented and illustrated with exhibits such as pier vending machines. Attached to the museum is Clara’s cottage, built in 1864 and is fitted out with furniture and household appliances for the family of Clara Payne, her husband and her four children who lived there in around 1900. At the time of our visit there was also, a special exhibition about the experiences of teenagers from the 1950s designed by young people of today.

AGM Talk Marcus Palmen, our web master, willingly stepped into the breach, when David Hole was forced to pull out due to having an operation. He gave us a fascinating talk on “His Boyhood Experiences in Europe during World War II”. Marcus had to explain first that he was born in Finland and brought to Hull by his parents in the 1930’s and they were here when war broke out. Marcus’s father was a seamen’s padre with the Lutheran Church. They were required to return to Finland in 1941, so the story was about this amazing trek across Europe at the height of the hostilities. The family left the UK in a Flying Boat from Poole Harbour to Lisbon, then by plane to Madrid. There they caught a German plane to Berlin and then by train to the Baltic and by boat to Helsinki. We were all pleased to hear that the family returned to Hull after the war, which explains Marcus being with us today. John Gale Newsletter index
Portsmouth Report Members, wives and friends, a complement of 36, descended upon the Queens Hotel, Southsea, a gem of Edwardian splendour, on Friday evening of the 19th April for a “Sea-faring Weekend”. The first evening’s dinner was followed by a talk by a Portsmouth Tourist Office guide, who was positively gushing with enthusiasm about the many things to do and see in Pompey.
Members News Patrick Bilyard – Patrick and his wife were due to join us at Portsmouth, but due to illness, he had to pull out. We wish him well. Temple Back Development The redevelopment of the Temple Back site (Bristol’s first generating station in 1893) is nearing completion with only the front façade retained since it had a preservation order on it. The scheme offers 125 sq.ft of office space possibly housing around 100 people. The new building is anticipated to require very low energy costs 50% lower than other 1990’s buildings in Bristol. The agents said that low energy consumption is increasingly important since Energy Performance Certificates for commercial premises are due to come into effect later in the year. Newsletter indexNight In 1940 This participative blitz evening organised by member, John Dike, was a great success in Backwell in March in the local WI Hall. You may recall that SWEHS were intending to run this, but decided that we wouldn’t get enough people to attend and so my wife, Valerie, took on the challenge with the help of Backwell Drama Club, who sold 90 tickets at £10 each to include supper, all in aid of a charity.
Nuclear Archive The National Nuclear Decommissioning Authority are to invest £8M to create a UK Nuclear Archive. It is to be built near Caithness Airport in Scotland. This is surely a surprising choice of site, since it is not the most accessible place in the UK. Newsletter indexBangkok North Power Station (Electricity Generating Authority of Thailand - EGAT) Fig.1 Bangkok North Station set no.3 This station had an installed capacity of 237,500 kW, and as originally built it was designed to burn either lignite or oil and the lignite conveyors were installed. As far as I am aware this station only ran as an oil-fired plant. Combustion Engineering Inc supplied the three boilers; those for units 1 & 2 generated 580,000 lb of steam per hour at 1,495 psig and 1,005 deg F, while the boiler for No 3 unit was rated at 700,000 lb of steam per hour at 1,500 psig and 1,010 deg F. The steam turbine generator sets were supplied by General Electric and units 1 & 2 were rated 75,000 kW each, generating a three phase, 50 Hz current at 13.8 kV, at a speed of 3,000 rpm; the unit transformers were each rated at 90,000 kVA, with a low voltage of 13.2 kV and a high voltage of 69 kV. No 3 Unit was rated at 87,500 kW at 3,000 rpm, the unit transformer being rated at 105,000 kVA; all of the alternators at this station were hydrogen cooled. This station remained operational until after the turn of the century, the site has now been cleared and I understand that a new combined cycle gas turbine gas fired station is now being built on this site. Fig.1 Bangkok North Station set no.3 The other large thermal station at Bangkok South remains in service, when I visited it in September last year a new combined cycle gas turbine station was in service on an adjacent site, with the structural steel work in course of erection for a second such plant.

Marine Turbines The World’s first deep-water device is to start generating electricity within weeks. The first free-standing turbine has been lowered into place at the SeaGen Tidal System at Strangford Lough, County Down, N.Ireland. The system is made by Marine Current Turbines (MCT) based at Stoke Gifford north of Bristol, and assembled at Harland & Wolff Dockyard. The 1.2MW turbine has two 16m blades which will be turned by the water streaming in and out of the Lough.
Bigger Biomass Station Approval has been given for the world’s largest biomass power station, which is to be built in Port Talbot at a cost of £400M. The station, to be fuelled by wood-chips, will be built by Prenergy Power and completed by 2010. The Times article never stated the KW size other than it would be eight times that of the UK’s biggest at the moment. The crazy thing about this project is that the wood-chips will be imported from “sustainable forests” in the Americas. The chance of guaranteeing the sustainable bit seems pretty slim to me. Existing Nuclear British Energy is hoping to extend the lives of two of its Nuclear Power Stations by ten years – they are Hinkley Point B and Hunterston B. They have permission to extend from 2011 for another five years. They plan to spend £90M over the next three years upgrading the reactors, boilers and transformers. At Oldbury, which is to be taken out of service this year, a publicity campaign is being mounted on the decommissioning strategy up to 2018.

Smart Meters Austin Philp from WPD attended a conference on Smart Metering at the IET, Savoy Place recently on behalf of the Union Prospect. The importance of Smart Metering was expressed as encouraging consumers in more energy efficient use and will eventually remove the need for meter reading and estimated bills. Pretty challenging stuff! A representative for the Government body BERR (Department of Business, Enterprise and Regulatory Reform) was present, but Austin was quoted as saying that it would be difficult with the fragmented nature of the ESI, posing massive interoperability problems. Newsletter indexSolar Power There is such a demand for solar panels that there is now a shortage of Silicon, the major material involved in constructing solar panels. The specific material is polysilicon converted from common sand by a heating process into a very refined crystalline form. The German manufacturer is proposing to double the size of their factory output. A few more factories would be needed if the idea put forward by Jordan’s Prince Hassan recently to build millions of solar panels in the North African deserts. Thus capturing the wasted sunlight and transmitting the electricity to Europe via cables under the Mediterranean Sea – or should I say “piped under”, since it might be a pipe-dream! Home Wind Turbines I believe that our members are not rushing out to install wind turbines on the houses. Just as well since I have read that they are not very successful. Firstly it would take 15 years to recoup the ‘green energy’ to compensate for the energy used in manufacturing the turbine in the first case. They are also less efficient than publicised due to wind speeds being roughly a third of those predicted. Thus it would take years to rcoup the money spent on the installation.
Acquisitions Two archival items have been deposited with us, the first by new member Ian Hopley, being detailed papers about the mathematical formulae formulated by Clerk Maxwell after considerable research by Ian. The other is the Operating Manuals for East Deptford Power Station, which we wouldn’t normally keep, but we decided that they would be a typical reference of that period.
Galileo Galilei It is anticipated that there will be a celebration next year for the 400th anniversary of Galileo building his first telescope in 1609. As most people know, he was tortured by the Roman Church to recant on his then advanced views of the planetary system, so it is pleasing to note that he is being rehabilitated by a statue being erected in the Vatican Museum gardens. Newsletter indexThermostats Following the death of a baby in Taunton in 2007 caused by an exploding hot-water tank, it has been revealed that thermostats controlling immersion heaters need to be designed to a certain standard incorporating a fail-safe switch, which turns the device off, if the thermostat fails. Many local authorities will now be faced with replacing all their older thermostats. Newsletter indexCongratulations - - - to all those born in the 1930's, 40's, 50's, 60's 70's
Sageism You don’t stop playing when you get old, you get old when you stop playing! Improved Hi-Fi This story was reported in the HI-FI Critic Journal last year. A HI-FI enthusiast lost his electricity supply and when it came back he was surprised that his HI-FI was noticeably better. He asked the utility fault engineer, who was in the vicinity, what had he done? The answer was that he only replaced the substation fuse with a larger one. The enthusiast decided that the source impedance had been reduced!! Newsletter indexStriding Pylons Ref your newsletter from August 2005: I’ve been searching for the music for the “striding pylons” power company advert for years, and think I’ve found out what it is - Tchaikovsky’s Violin Concerto in D (1st movement) about 6 minutes into the Itzhak Perleman recording (available on i-tunes).
