This was a big farce and they were no financial back up at any time the idea was brilliant and some other company with a financial side may well take over this project. ..with the backing of the irish and English goverments..hope it will be pursued. ..and will give the west coast a big boost financialy...why are they not more media briefing on this project spirit of ireland are now deleted from this project...but not entirely abandoned they are now talks with an american company based in canada 'who are extremly interested in the project' it seems donegal is ear marked for such a project as it is best suited for sea water levels...the valley that is been investegated is in the most remote part of south west donegal'but has sufficent evidince that the project would be extremly hard to ignore..they are ongoing tests been carried out at a regular basics......s

All a bloody farce and totally unfeasable due to economics...unless of course the Irish people are happy to continue overpaying to keep a small amount of individuals in a very cosy lifestyle. Huge land mass considering the population so power will always be expensive to deliver. Best senario for a population of cica 4.5 to 5 million or 1.2 million dwellings would be a single nuclear plant. quick cost effective and clean with a full 50 years of supply. It would generate about 7000 jobs in one go plus a supply chain of another 2000 for approximately 7 years. Work for 2 generations on site during the productive life and then the decommissioning. What are you eaiting for Ireland. Oh! and for those against nuclear power. Statistics report that a total of 13 million nuclear medicine procedures are performed each year within the United States. Think about the thousands of people who survive cancers now thanks to it, including people in Ireland.

A null-hypothesis is a default position. To overcome the null-hypothesis you have to show a certain statistical significance (or probability) that the evidence fits your hypothesis better than the default position. We’re not talking about absolute proof, just probability. Let’s use gravity as an example: The evidence that best fits the theory (by a high probability) is that gravity is generated by mass. If you were to say that gravity used to be generated by mass but now it’s mostly people, you had better be able to show a high probability that the evidence fits your hypothesis better than the current default position. If you didn’t you would be scoffed at. However, human caused climate change has never done this! The evidence fits the null-hypothesis like a glove. Why? Climate change is the norm, not the exception! It always has and always will change. There is not one paper that falsifies the null-hypothesis! By not overcoming the null-hypothesis, the human caused climate change hypothesis does not even qualify as a theory. These people who play it as a fact, are in fact in denial of the scientific method!

Why can't wave power be used to pump sea water to the reservoirs? Why can't wind generated electricity be sent direct to existing HEP reservoirs in N Wales?

Val Martin says: 16 Jun 2012 22:00

Spirit of Ireland plans are a fraud, a ponzi scheme. They admit that it will be fossil fuel generated grid power which will power the pumps to pump the water up the hill. This is common sense as there is no wind on a calm day. Its just a money grabbing exercise with the Irish consumers being robbed. See valmartinireland you tube myth about wind energy

David Spurrgeon says: 03 Apr 2012 16:30

Large wind turbines require a large amount of energy to operate. Other electricity plants generally use their own electricity, and the difference between the amount they generate and the amount delivered to the grid is readily determined. Wind plants, however, use electricity from the grid, which does not appear to be accounted for in their output figures. At the facility in Searsburg, Vermont, for example, it is apparently not even metered and is completely unknown [click here].* The manufacturers of large turbines -- for example, Vestas, GE, and NEG Micon -- do not include electricity consumption in the specifications they provide. Among the wind turbine functions that use electricity are the following:† yaw mechanism (to keep the blade assembly perpendicular to the wind; also to untwist the electrical cables in the tower when necessary) -- the nacelle (turbine housing) and blades together weigh 92 tons on a GE 1.5-MW turbine blade-pitch control (to keep the rotors spinning at a regular rate) lights, controllers, communication, sensors, metering, data collection, etc. heating the blades -- this may require 10%-20% of the turbine's nominal (rated) power heating and dehumidifying the nacelle -- according to Danish manufacturer Vestas, "power consumption for heating and dehumidification of the nacelle must be expected during periods with increased humidity, low temperatures and low wind speeds" oil heater, pump, cooler, and filtering system in gearbox hydraulic brake (to lock the blades in very high wind) thyristors (to graduate the connection and disconnection between generator and grid) -- 1%-2% of the energy passing through is lost magnetizing the stator -- the induction generators used in most large grid-connected turbines require a "large" amount of continuous electricity from the grid to actively power the magnetic coils around the asynchronous "cage rotor" that encloses the generator shaft; at the rated wind speeds, it helps keep the rotor speed constant, and as the wind starts blowing it helps start the rotor turning (see next item); in the rated wind speeds, the stator may use power equal to 10% of the turbine's rated capacity, in slower winds possibly much more using the generator as a motor (to help the blades start to turn when the wind speed is low or, as many suspect, to maintain the illusion that the facility is producing electricity when it is not,‡ particularly during important site tours) -- it seems possible that the grid-magnetized stator must work to help keep the 40-ton blade assembly spinning, along with the gears that increase the blade rpm some 50 times for the generator, not just at cut-in (or for show in even less wind) but at least some of the way up towards the full rated wind speed; it may also be spinning the blades and rotor shaft to prevent warping when there is no wind§ Could it be that at times each turbine consumes more than 50% of its rated capacity in its own operation?! If so, the plant as a whole -- which may produce only 25% of its rated capacity annually -- would be using (for free!) twice as much electricity as it produces and sells. An unlikely situation perhaps, but the industry doesn't publicize any data that proves otherwise; incoming power is apparently not normally recorded. Is there some vast conspiracy spanning the worldwide industry from manufacturers and developers to utilities and operators? There doesn't have to be, if engineers all share an assumption that wind turbines don't use a significant amount of power compared to their output and thus it is not worth noting, much less metering. Such an assumption could be based on the experience decades ago with small DC-generating turbines, simply carried over to AC generators that continue to metastasize. However errant such an assumption might now be, it stands as long as no one questions it. No conspiracy is necessary -- self-serving laziness is enough. Whatever the actual amount of consumption, it could seriously diminish any claim of providing a significant amount of energy. Instead, it looks like industrial wind power could turn out to be a laundering scheme: "Dirty" energy goes in, "clean" energy comes out. That would explain why developers demand legislation to create a market for "green credits" -- tokens of "clean" energy like the indulgences sold by the medieval church. Ego te absolvo. (One need only ask utilities to show how much less "dirty" electricity they purchase because of wind-generated power to see that something is amiss in the wind industry's claims. If wind worked and were not mere window dressing, the industry would trot out some real numbers. But they don't. One begins to suspect that they can't.) *There is also the matter of reactive power (VAR). As wind facilities are typically built in remote areas, they are often called upon to provide VAR to maintain line voltage. Thus much of their production may go to providing only this "energy-less" power. †Much of this information comes from a Swedish graduate student specializing in hydrogen and wind power, as posted in a Yes2Wind discussion. Also see the Danish Wind Industry Association's guide to the technology. The rest comes from personal correspondence with other experts and from industry spec sheets. ‡An observer in Toronto, Ontario, points out that the blades of the turbines installed at the Pickering nuclear plant and Exhibition Place turn 90% of the time, even when there is barely a breeze and when the blades are not properly pitched -- in a region acknowledged to have low wind resource.

I hope the project is still on course. It would be such a shane if there are red tape issues holding up the show

Eamonn says: 28 Jan 2012 1:44

Anybody know whats going on now with regards this fantastic project. I saw lately on Irish Times that Enercon (a german wind turbine manufacturer) is readying to set up in west of ireland to build the turbines for this project.

D. Cullen says: 31 Oct 2011 1:35

I am amazed at the self interested objections of people who have not even taken the time to investigate the potential of this project for the good of all the Irish population.

Alan says: 24 Oct 2011 15:23

Asked the same question this time last year,, When , when , when.... this looks like a no brainer. why are people not jumping up and down about this.

Spirit of Ireland Group

About the Speech:

Graham O'Donnell and Professor Igor Shvets presented and discussed the group’s recently announced strategy to make Ireland energy independent within 5 years and a net exporter of energy thereafter through the large-scale deployment of wind farms and hydro storage on the West Coast of Ireland. Through the use of Wind Power they hope to change Ireland's energy landscape.
