In the wake of Fukushima disaster, energy experts now agree that securing Europe's future electricity supply will require an increasing convergence between existing fossil fuel sources and the fast-growing renewable generation sector. Nowhere is this fusing of interests required more than in Germany, in the light of the government's decision to phase out all nuclear power by 2022. The case for integration is now compelling and is something that an increasing number of countries are going to have to consider.

The current debate among those in the power industry is how Germany will fare without a new generation of nuclear power plants and the phasing out of the existing fleet, coupled with growing opposition to coal-fired generation. Many in the industry feel that the technology most likely to benefit in the short term is gas fired generation, but that the recent nuclear-free policy offers Germany a chance to be a pioneer in a new energy system, which matches a substantial green energy sector with a conventional generation base. Chancellor Merkel has already said that her country's "fundamental" rethink of energy policy could set an example for other countries. If this is to be the case, significant new infrastructure will be required, not only in the area of power generation, but also in the transmission grid and the way that the grid interacts with these power sources. Germany's offshore wind potential is large but its prime location is a long way from the main load centers. In addition, protest groups are already expressing their fears that the unspoiled, forested center of the country will become a north-south "energie autobahn" of pylons and high-voltage cables.

However, renewable energy groups in Germany such as the BDEW Association remain optimistic. They say that Germany is unlikely to experience blackouts in the next decade as the country currently enjoys a surplus energy capacity, has a good potential for energy efficiency savings and has strong border interconnections in place.

On the other hand, RWE chief executive Jürgen Grossman has argued that, until low-carbon energy sources improve, Germany will struggle to meet its greenhouse gas reduction targets in the absence of nuclear power. His colleague Volker Beckers, Group CEO of RWE nPower said recently that "Germany has a romantic view of energy policy", and described this policy as misplaced and damaging.

Whatever your position on this issue, it is clear that Germany's power sector will experience a period of change and that traditional power sources will need to be integrated with renewable sources such as wind and solar to create a smart energy solution. The decision on nuclear power may be the catalyst needed to jump-start this revolution.

If the lights are to be kept on at all times, the smart energy system of the future needs to provide the necessary flexibility to allow new low or zero carbon power generation sources to be added to the grid. Technology development is being geared toward providing flexible solutions that enable integration of variable renewables and conventional power and these solutions are now being brought to market. Technologies addressing the challenge of integration include flexible gas turbines, fast-ramping gas and diesel engines, hybrid power plant designs, energy storage, new HVDC designs and smart grid technology.

At a strategic level, Europe's utility companies and equipment suppliers need to communicate and collaborate in order to design the integrated power system of the future. The renewable power generation market now recognizes the need for close co-operation and integration with the mainstream as green power becomes big business for the major power generating companies across Europe.

European energy policy is also being driven by a need for further integration between national energy policies, neighboring grid systems, future R & D efforts and long-term strategy. A pragmatic approach is going to be vital. While a zero-carbon, 100 per cent renewable power grid is the dream for many, for the foreseeable future the power sector in Europe is going to have to work with the sources it has available. The time has come for the all the major actors to join forces in order to deliver a cleaner, reliable and affordable electricity supply for future years.

This is an interesting article, because it is both interesting and important for all the countries in central Europe, and perhaps a few more. But all of it cannot be taken at face value.

GERMANY IS NOT GOING TO DUMP ITS NUCLEAR! It is easy to talk about it now, since that country is still comparatively prosperous, but when the reality of higher energy prices is presented to German voters, they will get the message.

Less than a year ago Merkel was running around shouting about the need for more nuclear, but when she realized that by doing so she was risking her politicak career, she joined the anti-nuclear booster club. The naive voters and probably politicians in countries adjacent to Germany do not seem to understand, so perhaps this is the place to explain it to them. Wind and solar will not do what many voters have been told that they can do, and so Germany will buy power from other countries. That means that nice people like myself will end up being punished to buy Merkel another three or four years in the limelight.

An important Belgium gentleman told a conference I attended that if Germany tries to realize Merkel's foolishness, in five years Belgium might have to ration electricity. Of course, as I pointed out, in five years Belgium can construct the largest nuclear facility in the world, and pass a law which says that Germany does not have access to its output.

Yes, the bottom line is still nuclear plus renewables and alternatives, but what is being considered in Germany at the present time is dumber than stupid.

The main problem with Fukushima Power station is that is was located on the wrong side of Japan . . . the Pacific side with a high propensity for tidal waves. The north shore along the Sea of Japan is less susceptible to such waves . . . . and Japan apparently does have some seawater-cooled thermal power stations along the northern coast.

Chancellor Merkel's stand opens the door to import hydroelectric power and geothermal power via undersea power cable from Iceland. There are 2-groups of islands along the route of the proposed cable, where it may be possible to build seawater-cooled nuclear power stations that sell electric power to Germany and desalinated seawater to other customers.

"protest groups are already expressing their fears that the unspoiled, forested center of the country will become a north-south "energie autobahn" of pylons and high-voltage cables" -- The most important sentence in the article. In other words, "No nuclear, no wind, no solar, no imported energy". Have the voters of Germay been made aware of the real plans of the anti-nuclear protesters?

Ferdinand E. Banks

Len, when the German voters in Hamburg were paid a midnight visit by the RAF that set a large part of that city on fire, Goebbels came up a day or so later and told them that the war as as good as won if they kept murdering women and children. Naturally, many people did not believe him, but I suspect that a majority did. In fact, with the Russians in the Berlin suburbs and the allied air forces turning German cities into rubble, highly educated and aristocratic Germans let Hitler get away with his foolishness.

Conclusion: Goebbels was right when he said that the bigger the lie, the harder (a majority of) the people will try to believe it.

I welcome the responses to my article and and most interested my the range of views expressed. Although all European countries have their unique power infrastructures, fuel sources and national legislation, the German experiment is an important tersting ground for policies coming out of Brussels. Power industry practictioners have to have their say on this. For that reason, I am organising a debate on the subject at POWER-GEN Europe (www.powergeneurope.com) in Cologne on 13 June under the title, "German Power Policy - solution or illusion?" I hope we will hear some home truths from the industry there and in the meantime welcome any other contributions to the discussion.

What does it mean to the rest of Europe? The French are going to make a lot of money selling nuclear generated electricity to Germany!

As for renewable energy, it's really too expensive as well as unreliable and sooner, rather than later, the extra burden on the increasingly fragile European economies will be too much to bear. Spain provides a pretty good example, as subsidies for renewable energy are being heaved over the side (the lads are running out of other people’s money) as the Spanish economy takes on more and more water.

From the point of view of the US, I think Europe’s self-inflicted plight is great; our competition is pricing itself out of the global marketplace. We, on the other hand, have ample supplies of natural gas, with the “green agenda” starting down the road to economic reality. By that I mean, if “green energy” can not compete, then it fades out of the marketplace. I think nuclear power in the US faces a similar fate unless costs can be significantly reduced.

In closing, the whole idea of "zero" carbon is inane on many levels, from economics to the climate as a whole. Try as they might to avoid it, reality is simply going to overwhelm those pushing the green religion. Unfortunately, large segments of the population will end up paying the economic price for fundamentally stupid policies promulgated by politicians and their cronies lining their pockets at everyone else’s expense.

P.S. Perhaps some missed this, but a number of the German nuclear units were brought back on-line during the recent cold snap.

Ferdinand E. Banks
2.18.12
Noel, a debate isn't necessary. What is needed is some propaganda. The most intelligent politician in Sweden (perhaps) believes that nuclear can be dumped and replaced by renewables, and there are plenty of other people in Sweden and elsewhere who believe this foolishness. Merkel says that she believes it too, however what she really believes is another term in office would be lovely, and perhaps the way to get it is to support a nuclear retreat.

When they had a discussion of this topic on TV in Sweden a couple of months ago, a man who is professor of physics and a staunch believer in nuclear could hardly get his pro-nuclear sympathies out of his mouth.

Where the reduction of nuclear costs in the US are concerned, this is not only possible, but there should be people in the US Energy Department who can provide the information we need. Unfortunately however, Dr Chu is as incompetent as his president, so I dont think that we will get much help from him and his foot soldiers.

Len Gould
2.19.12
I'm curious Fred. You keep repeating that "Obama is incompetent" and I'd like to find out why your say that? Is it simply your hope that your constant repetition might have a subconsious influence?

Michael Keller
2.20.12
Fred, I do not share your confidence in the prowess of the US Department of Energy. Quite the opposite, actually. Nuclear power is expensive because of the large amounts of steel and concrete needed to build the units coupled with the stifling regulations/bureaucracy that significantly extend the construction schedules. There is no "magic nuclear cost reduction bullet" hidden in the bowels of the US government other than perhaps getting rid of counterproductive and needless regulations (and bureaucrats).

As for Obama, he is not only incompetent, but corrupt to boot. Just about every policy he has created is taken from the "big government" playbook, with end result of visiting economic ruin on the average American. What is more, the goal of most of the policies is to pay back his contributors, with the ultimate aim of getting re-elected, thereby increasing his (and his followers) wealth and power. While that is always an element of just about any political operation, Obama has taken it to an extreme that is severely damaging the future of the country.

Ferdinand E. Banks
2.20.12
Len, Michael Moore put it this way: HE HASN'T DONE WHAT WE ELECTED HIM TO DO!

I keep saying that he is incompetent because he hasn't done what I want him to do: end those stupid wars, and put the money wasted in them into the kind of educational system that I want and the US needs - and here I am NOT talking about universities. Aside from that, I also think that Romney is better for the US than Mr Obama - a lot better in fact - and this time I think/hope that the American voters might get the message.

The thing I especially can't stand about Mr Obama however - and please note my language - is that he makes the kind of mistakes that an intelligent man should not make. For instance, what or who gave him the idea that Dr Chu knew what he should know? People tell me that if he gets four more years, he will straighten up and fly right. That is something like expecting George W. Bush to stop ruining the American economy with his nonsense - and not just the American economy. Most of us except the rich are in trouble because of George. and that includes yours truly.

I'd love to have another description for Mr O.,and I also know that the American voters might supply us with another bungler, but assuming that the Republicans can find somebody to run who can add two plus two, then I think that we can dispense with our president. But please note: I was afraid that the race thing might work against Obama, but fortunately it didn't. What I am afraid of now is that it might work for him, because that soap opera showing him sitting in the White House situation room waiting for the denouement of the Bin Laden episode was about the saddest thing that I could imagine an American president doing.

Ferdinand E. Banks
2.21.12
Michael, I have no confidence at all in the prowess of the USDOE, but there is one thing I am sure that they can do if they had the right director: supply us with accurate information about the US and global energy scene. I am certain of that. For instance, why is it that so much nonsense comes through on shale gas. Shale gas is very likely important, but when 'they' start talking about a hundred years at present or future output rates, I know that something is very wrong.

As for the position of the government in all this, it is their job to make sure or try to make sure that if or when the (aggregate) oil price goes up by another twenty dollars, we will not have to experience another macroeconomic melt-down. This is what the voters and non-voters want their government to do, although they may not be aware of it. AND THE GOVERNMENT PLAYS A CRUCIAL ROLE HERE, JUST AS THEY DID IN WW2. Where the oil price is concerned - which is a tax on all of us - OPEC is in the drivers seat, and only the government - or a consortium of governments - can do something about it.

You say that Obama is corrupt. Maybe he is and maybe he isn't, but I doubt it. He is just plain incompetent. He doesn't have the right reflexes for that job. If they had wanted a president from Chicago, and Al Capone had still been alive, he would have been a better choice. As for the corrupt people, those are the millionaires dreaming about becoming billionaires instead of making the US what it could and should be.

If Merkel’s decision is indeed based on reelection reasons, then her decision would have to rank as one of the most venal in history and an insult to the German people. Or is the German electorate once again failing to understand the problem and being patronized?

So many failures in such a short time - when was it, 1870? (That’s when my grandparents were being born) they became a country. In the 30’s they were perhaps the best educated and most sophisticated country on earth.

Ferdinand E. Banks
2.23.12
Don, six or seven months before Merkel brought forward this nuclear retreat foolishness she was talking about the need for more nuclear. However, I really and truly would not care what happens in Germany if it would not cost be equivalent to a tax on me.

The German economy is strong enough now to purchase electricity from the surrounding countries when or if they close the German nuclear facilities. IThe strong get stronger although they may lose their charms in the end. In the world that I would like to see or manage, I would let the Germans dump their nuclear, and then prohibit most or all of the electric exports to them. That may not change their mind about nuclear, but it would depress the ruinous electric prices we often have to deal with in this country.

Malcolm Rawlingson
2.24.12
Ms. Merkel is a politician. As Fred so eloquently puts it her job is to get re-elected and she cannot do that by supporting nuclear power. That does not mean that she does not support nuclear power. She is also a physicist and knows full well that German nuclear plants are safe. So how does a smart politician dig herself out of that one. Well one shuts down the local nuclear fleet (no loss of jobs since it takes many years to de-comission a nuclear plant) and imports nuclear electricity generated in France and the Czech republic. That is where Germany is getting its electricity - not windmills or solar panels.

So she still is supporting nuclear power (in France) has lost no jobs (in Germany) keeps the competitive edge because French nuclear power is still relatively inexpensive AND she makes it APPEAR like she is pro-environment by appearing to shutdown nuclear industry in Germany. It is actually quite brilliant. She is of course a complete liar and a hypocrite but she is a politician after all.

Once Fukushima fades from the headlines and the amount of spare capacity France has to sell decreases she will start them all up again....just as Japan will do.

Harry,

Bringing Geothermal Power from Iceland to Germany - you gotta be nuts. That project would cost trillions. Laying undersea power cable is a very very expensive business. They would have to be DC links as plopping 500 kV lines under the sea would pose massive problems.....there is a reason why 500 kV lines are high up in the air. Air is an insulator seawater is a conductor - a very good one. It is not quite as simple as drawing a straight line between a couple of islands on a map the the earth. The line losses alone would be staggering. You need to rethink that idea.

Not sure what you were saying about seawater cooled plants in Japan...they are ALL seawater cooled and they are ALL on the coast for that very reason. I had the opportunity to visit Takahama Nuclear plant some years ago. Very well run plant.

As noted the Japanese will find that the cost of importing oil coal and LNG will destroy their economy and like Germany will restart all their nuclear plants. Merkel is awaiting a recession that will inevitably hit Germany as her opportunity to start up the nuclear plants again.

Nigel,

The grid in Europe already is a highly integrated system. That is what is keeping the lights on in Germany. If you think it is a few windmills and a few solar panels running German industry - give your head a shake - twice.

If the wind power business in Europe is so good how come Vestas in Denmark is laying off thousands and going broke? Using gas turbines and diesel generators will keep Germany dependent on Russian oil and gas supplies. Great for Gazprom stupid politics for Germany. And storage systems - where? This notion of a 100% carbon free electrical system can only be accomplished with nuclear power. Nothing else comes close to being able to do it. For the last 40 years all I have heard of is these great technological breakthroughs in battery and other technologies that are "just around the corner" ready to transform the electricity business and here we are 40 years later using the same technology we always have - because it works.

As for wind and solar power - it only works economically when subsidized by government and if you dig into the financial woes of Spain and Portugal you will see that billions of dollars of borrowed money have gone into idiotic power schemes that are not financially viable. These subsidies are - as someone noted above - being ditched overboard as the economic realities of life start to hit home hard in these countries.

Should Merkel not be lying to her population and leaves German nuclear plants off line for an extended period you will see the German industrial machine stopped in its tracks and it's products becoming increasingly expensive and uncompetitive.

The German people - as pragmatic as they are will sooner have nuclear power than a third world standard of living like they are trying to impose on Greece.

Malcolm

Ferdinand E. Banks
2.25.12
Malcolm, the Germans have not imposed anything on the Greeks. They imposed it on themselves by joining the EU and the European Monetary Foolishness. This country - Sweden - is full of fools who voted for Sweden to go into the EU, thinking that they would win on the deal. Note the word "fools". Isn't that the right word for giving up control of your borders, and on top of that deregulating electricity because that suits the morons in Brussels.

Malcolm Rawlingson
2.25.12
Thinking about it Fred - you are right on. The Greeks really did it to themselves although I do not think the Greek people themselves ever voted for the EU but they did vote in the politicians who thought they were entering the land of milk and honey. The UK (my birth country) adopted the same foolishness as Sweden. Now you get prosecuted for selling bananas in pounds instead of the dictated kilograms. Complete and utter stupidity.

Malcolm

Malcolm Rawlingson
2.25.12
Well, I heard today that Germany has just restarted three of its shutdown nuclear reactors because of the cold weather across the country. Ha Ha. What a joke Merkel is.

Apparently German people do not want to freeze to death. Just cannot imagine why. I wonder if GreenPeace is distributing blankets? Did not hear that as headline news on the media did we? Do you think the media is a tad biased against nuclear. I think it is now fully self evident.

Where are all the global warming pundits in Europe now? Wasn't is supposed to be getting warmer??

Or does global warming mean it is getting colder. Oh - I forgot - it's climate CHANGE now not global warming so that means we can blame all cold spells and all warm spells and all normal spells on CO2. Any weather pattern at any time in the future is now due to CO2.

I get it now - we can blame EVERYTHING on Global warming - even the need to start up dangerous German Reactors. Or did the cold weather suddenly make them more safe. Yes that is it. Cold weather makes nuclear reactors in Germany safer so they can be started up. That has to be good for a Government funded research program.

Malcolm

Ferdinand E. Banks
2.26.12
They could have another nuclear incident in Japan tomorrow, Malcolm, and the Japanese would still turn to nuclear.

They have no choice, and the Japanese people are intelligent enough to get the message - now or later. I have some doubts about the people who own that country however. The last time I was in Japan I was told that regardless of what students and teachers in general thought, Tokyo University is still the only university that counts if you want to buy into the Japanese ruling clique.

What I do absolutely believe though is that no more mistakes will be made in the location, construction, management or regulation of nuclear facilities.

Len Gould
2.28.12
I find the direection of the conversation above has a couple interesting points. On the EU zone problems, I've concluded that the sentiment to create the EU zone was correct, but the implementation was flawed. The flaw was leaving ANY country / currency in the world outside the saystem. As long as there are two or more currencies in the world, speculators and traders will exploit issues of timing, demographics etc. to cream off a "false profit" (LOL) by trading among them, and corrupt politicians will exploit methods such as inflating away debts, excesive borrowing in foreign currencies etc. etc. in the short term to get re-elected regardless of the long-term consequences. Only a single world currency makes any sense in this "free-trade world". Continuous endless problems similar to present until then.

On solar generation, solar thermal with thermal storage in many areas would be competitive now AFTER the efficiencies and improvements gained by building an initial 8 GW (see Sargent & Lundy engineering study). That first 8 GW needs to be done rapidly enough to exploit the advantages of volume manufacturing, and it needs to be subsidized because the first 8 GW will not be cheaper than competitors (especially N Gas at these prices. Suspicious?) and therefore private capital can't build it. After the economies of scale develop with the first 8 GW THEN solar thermal will compete on the market with any other fuel, and will provide increasing reliable baseload generation, with small amounts of N Gas backup, as the prices drop. That's how we should be doing things, gets us weaned off polluting our grandchildrens planet and leaves some fossil fuels for future generations.

But then, these things will NEVER get past entrenced interests of the wealthy.

Malcolm Rawlingson
2.28.12
Len, Sorry my friend but there are few things more polluting than making solar panels and covering large areas of land with them. That is NOT a legacy I want to leave my grandchildren. For a start these panels require silver which involves significant pollution of ground water at the mine site.The net amount of power you get back out of a solar panel is not worth the effort of making it. The energy density is far too low for any real practical benefit to humanity. Malcolm

Len Gould
2.29.12
Malcolm: "there are few things more polluting than making solar panels and covering large areas of land with them -- power you get back out of a solar panel is not worth the effort of making it" -- again, reference please (especially re solar PV being a user of silver). Your anti-solar tirades are beginning to sound desparate LOL.

Kent Wright
2.29.12
Len's Sargent & Lundy feasibility study on solar thermal completely ignored the actual availability of water in desert lands where solar input is at maximum. S&L seems to have made an assumption, apparently out of thin air, that plenty of water will be available AND at constant 1999 prices to boot! Plentiful and cheap water ain't gonna happen.

According to figures released by a University of Michigan study, the water consumption for parabolic trough, wet cooling, solar thermal is around 1000 gallons per MWh. Scaled to 8 GW is 192 million gallons per day, or 7 billion gallons per year. I think that means finding a couple more Colorado Rivers out there in the desert southwest somewhere. …or maybe we could pipe water down from Canada at a bargain price.

Len Gould
2.29.12
Kent: Is seawater available? Combining solar thermal condenser cooling with desalination facilities actually increases availability of fresh water. Perhaps a gravity feed from ocean into the below-sea-level depression inland in California. Or you can implement aircooled condensers with only about a 1.5% drop in efficiency.

Oh but I keep forgetting how the religiously anti-solar fossil fuel supplier crowd refuse to support anything which actually has a chance to support society until every last ounce of fossil fuel is gone.

Acquasol project - Australia

SOLAR THERMAL POWER GENERATION AND SEA WATER DESALINATION -- Stephen Kaneff -- Energy Research Centre, The Australian National University/ ANUTECH, Canberra A.C.T. Australia 0200

"Economic aspects are becoming favourable for the use of large dish-based systems, especially if associated with desalination."

Malcolm Rawlingson
3.1.12
Len, I just came back from Australia. It is really hot and sunny. It was not hot and sunny when I returned to Canada. As usual you cherry pick. I have said countless times here that solar electric and solar thermal are likely viable in hot sunny regions of the world----more suited to individual rooftop installations so there is no additional land use. You advocate their use everywhere and have yet to answer any of the basic questions for their use in cold climates which are:

1. It snows. Who will clear the snow from solar panels. 2. Last night here we had a typical sloppy wet ice mixed with snow storm. All the solar panels are covered in wet sticky snow and ice. Their output is zero. 3. We have short days in winter.

The onus is on you to come up with the data support a nut case idea that solar panels in Canada produce more energy than is used in their manufacture. I maintain that they do not. I do know that nuclear DOES work day in day out and I see first hand solar and wind often NOT working.

Malcolm

Malcolm Rawlingson
3.1.12
Well Len, I am not sure if you actually read the article you linked to or you really wanted me to take this article seriously. But let me point out something to you. It is on Page 30 of the report. It is a serious weakness of the system.

"In summary, for example, the conversion efficiency to produce steam at 500°C and pressure of 5 MPa, for insolation in the range 400 to 1100 W/m2, is about 90% (steam enthalpy at ground level to direct beam input) for a collector with clean mirrors"

Note CLEAN MIRRORS. As soon as they start to get dirty the efficiency drops like a stone. What makes them dirty in Australia.....sand and dust storms in the desert for one. They get covered in red dust. Everything in the desert is covered in the stuff. It gets everywhere. When I was there last year there were major forest fires in the Southern part of Western Australia. Any solar array would have been covered in soot. With thousands upon thousands of these mirrors who would get the job of cleaning them? The highly abrasive dust dust would wreck any mirrored surface in weeks - especially when blown around by the wind.

This article has not only convinced me that these systems will not work in Canada it also convinces me they will not work in hot countries. Great in theory but in practice it is a complete bust.

France has one of the installations described here which they built in the 70's. It seems that nuclear is a better choice for them. They did not build hundreds of these installations they built 50 nuclear plants instead.

I am concerned that your faith in solar is based on pure theory not on the necessary practicality of operation.

It reminds me of one of Alexander "Kingdom" Brunel's failures when he built an underground system that used a vacuum arrangement to move a train through a tunnel. It worked great on paper and it did work for a while until the rats which populate many underground tunnels in London took a liking to the vacuum sealant which was beeswax - and ate it. End of great engineering achievement.

Even great engineers get it wrong.

Malcolm

Len Gould

Malcolm. a) I'm advocating for the subsidizing of construction of 8 GW solar thermal in a relatively short time period, eg. 5 years. I know it won't be economic compared to fossil fuels, even in sunny southern California or Nevada, but then the next builds would be competitive, and from then on, as efficiencies of volume increase the competitiveness, the areas where the system would compete would rapidly expand until eventually it would include many areas in Canada. The payment of the needed initial subsidies to 8 GW should be as broad as possible, eg. federal US and Canada,

b) I don't think that dust / dirt is such a huge problem with the systems as you maintain. Could you provide a reference?

Len Gould
3.1.12
Initially the subsidies should go to a) licensing the reciever tube technology from eg. Siemens b) setting up manufacture domestically c) immediate research on advancement of receiver finishes, flexible connections and higher temperature collection fluids d) integration of de-salination technologies e) development of integrated fossil-fueled backup heating f) development of optimized dry condenser systems g) thermal storage systems. After 2 years for whatever low-hanging fruit can be gained with this effort, then begin constructing 1,500 MW / yr and subsidizing their output initially at 9 cents / kwh, ending after 8 MW at 0 cents / kwh.

Len Gould
3.1.12
(sorry, meant "after 8 GW")
