Painting Solar Cells onto Steel Building Products

Researchers at Swansea University are developing a new, eco-friendly technology that could generate as much electricity as 50 wind farms.

Dr Dave Worsley, a Reader in the Materials Research Centre at the University's School of Engineering, is investigating ways of painting solar cells onto the flexible steel surfaces commonly used for cladding buildings.

"We have been collaborating with the steel industry for decades," explains Dr Worsely, "but have tended to focus our attention on improving the long-term durability and corrosion-resistance of the steel. We haven't really paid much attention to how we can make the outside of the steel capable of doing something other than looking good.

"One of our Engineering Doctorate students was researching how sunlight interacts with paint and degrades it, which led to us developing a new photovoltaic method of capturing solar energy."

Unlike conventional solar cells, the materials being developed at Swansea are more efficient at capturing low light radiation, meaning that they are better suited to the British climate.

A research grant from the Welsh Assembly Government's Welsh Energy Research Centre (WERC) enabled Dr Worsley to work with leading metals group Corus to investigate the feasibility of developing an efficient solar cell system that can be applied to steel building products.

The success of the study led to the award of a three-year project worth over £1.5 million by the Engineering and Physical Sciences Research Council (EPSRC).

Swansea University is now leading a partnership with Bangor University, University of Bath, and the Imperial College London to develop commercially viable photovoltaic materials for use within the steel industry.

Paint is applied to steel when it is passed through rollers during the manufacturing process, and it is hoped that the same approach can be used to build up layers of the solar cell system. The researchers' aim is to produce cells that can be painted onto a flexible steel surface at a rate of 30-40m2 a minute.

Dr Worsley believes that the potential for the product is immense.

He said: "Corus Colours produces around 100 million square metres of steel building cladding a year. If this was treated with the photovoltaic material, and assuming a conservative 5% energy conversion rate, then we could be looking at generating 4,500 gigawatts of electricity through the solar cells annually. That's the equivalent output of roughly 50 wind farms."

Dr Worsley will be working closely with Corus to research practical, cost-efficient methods of mounting the system on steel structures, with a view to the eventual commercialisation of the product.

He said: "This project is a superb example of the value of collaboration between universities and industry, and it is definitely important for Wales. We have a genuine opportunity to ensure that Wales remains at the forefront of this technology worldwide, driving the industry and revolutionising our capacity to generate electricity.

"I think it shows great vision from the Welsh Assembly Government that they funded the initial feasibility study. Even if we are only mildly successful with this project, there is no doubt that we will be creating an exciting hi-tech steel product that will preserve the long term future of the Welsh steel industry."

Brett Favre: “4″ says “No More”

It’s hard to call yourself an NFL fan without acknowledging the omnipresent retirement talk surrounding Brett Favre the last few seasons. Whether it be a hasty press conference at a charity golf tournament to tell us he hasn’t decided yet, or the constant paralysis by analysis last offseason until he made it official; Favre has been toying with retirement for a few seasons now.

Ironically, it was THIS offseason when the chatter had died down some. Coming off a 13-3 season and an MVP-caliber performance (by far his best personal stats in years), most [myself included] assumed Favre would return in 2008 to make one more run at a Super Bowl title.

That’s what we all get for becoming complacent. :)

This morning, Brett “4″ Favre announced his retirement.

Listening to that voice mail, you get the sense of what enormous pressure Favre put on himself to improve on 2007. And he’s right, anything less than a Super Bowl appearance would’ve been “less” than what they accomplished this year in many people’s minds.Today is a day to salute one of the greatest QBs to ever play the game.Favre’s Accomplishments

  • Three time (3) MVP [the only 3-time MVP in league history]
  • Seven (7) All Pro selections
  • Nine (9) Pro Bowl selections
  • 253 consecutive starts [something that will probably never be broken]
  • 1st all-time, pass attempts (8,758)
  • 1st all-time, pass completions (5,377)
  • 1st all-time, passing yards (61,655)
  • 1st all-time, passing TDs (442)
  • 2 Super Bowl appearances
  • 1 Super Bowl victory

Favre's longevity, durability set him apart


Was Brett Favre the greatest quarterback in NFL history? Yes -- and no.

Your opinion depends on what it means to be the "greatest of all time." Are we talking about the quarterback who had the greatest four- to five-year peak, during which he dominated the game? Or are we talking about the quarterback who gave his team the most value over an entire career? Most of the time, when we talk about the greatest players ever, we sort of fudge the question, not judging on either criterion but rather smushing the two together.

When Bill James rated the greatest baseball players ever in his original "Historical Baseball Abstract," he chose a different route; James created two completely different lists, one for peak value and one for career value. That's also how we have to look at Favre's place in NFL history.

Favre won three straight MVP awards in the mid-1990s (one shared with Barry Sanders), but that three-year period doesn't even come close to ranking as the greatest three-year performance by an NFL quarterback. At the same time, there aren't many quarterbacks who played as well, for as long, as Favre.

In my book, "Pro Football Prospectus 2005," I published a long statistical analysis of the greatest quarterback seasons in modern NFL history. (It actually started as an ESPN.com piece, which you can read here.) Not a single Favre season finishes in the top 50, and only one (1995) ranks in the top 80. By comparison, Johnny Unitas, Roger Staubach and Peyton Manning each have four seasons in the top 50 (including one Manning season since the book was published). By including both rushing and passing performance, Steve Young comes out with four seasons in the top 20.

Favre's best seasons don't rank among the best of all time because his completion percentage just wasn't good enough. Favre set a career high in completion percentage (66.5 percent) his final season, and he never ranked in the top five in completion percentage during his peak years of 1993 through 1997 (although he led the league in 1998).

Of course, Favre didn't have a spectacular completion percentage because Green Bay's offense was built on high-risk, high-reward deep passes. Although Favre completed enough of those deep passes to be the best quarterback in the league at the time, he didn't complete enough for those seasons to count among the greatest ever.

In his best season, 1995, Favre completed 63 percent of his passes with 12.3 yards per completion. Since 1960, 24 different quarterbacks had at least one season in which they ranked higher in both statistics, including Young four times and Kurt Warner three times.

Favre also threw more interceptions and was sacked more frequently than many of the other great quarterbacks in their best years, and most of his best seasons (with the exception of 1996) came against a schedule of defenses that were below average.

For most of his career, Favre was very good, but not spectacular. What's spectacular is just how many of those "very good" seasons Favre had. Of course, Favre set all of the all-time passing records over the past two seasons, but what is impressive is that he didn't set those records by sticking around as a mediocre quarterback long after his time had passed. Based on our numbers, Favre had more value in his final season than every quarterback in the league except for Tom Brady and Manning.

At Football Outsiders, we use our complex DVOA (Defense-adjusted Value Over Average) metric to break down every single play of the season and figure out how good each player is compared to the average player at his position. Our play-by-play database goes back to 1995, so it includes most of Favre's career. Only once, in 1999, does Favre come out as a below-average quarterback -- and just barely.

In 2005, Favre threw a league-leading 29 interceptions, and most observers believed he had hit the end of the line. Yet even that year, Favre was an above-average quarterback when you consider his team's schedule. Green Bay played six games that season against the four defenses with the most interceptions -- Cincinnati, Chicago, Minnesota and Carolina -- and another two games against Detroit, which ranked seventh.

If we assume that Favre was above-average in his first three seasons as a starter -- a fairly safe assumption -- that means he gave the Green Bay Packers 15 years of above-average play at the game's most important position -- and he did so without missing a game after taking over the position in early 1992.

Compare that to the other quarterbacks who are considered to be among the best ever. Joe Montana was injury-prone for the second half of his career. Unitas struggled once he got into his mid-30s. Young had the greatest peak of any quarterback in history, but he played only nine seasons as an NFL starter. Staubach started for only eight.

Combine quality and longevity, and the only quarterbacks who can compare to Favre are John Elway and Dan Marino. Many fans would say that the greatest quarterback career in history would have to include at least one championship, and that would narrow it down to Elway and Favre.

As to which of those two men had the greatest quarterback career in history, well, we'll let the Denver and Green Bay fans fight it out for the next 10 years. At some point, Manning and/or Brady may pass them both, but nothing guarantees that Manning and Brady will stay consistent and healthy throughout their 30s. Not many quarterbacks do, and that's what made Favre unique.

Robert Manne - Feb 2008 Comment from The Monthly

There are two distinct questions concerning the political events of late last year which it is important not to confuse. Why did the Howard government lose office? What does the Rudd victory mean?

Attempting to find an answer to the first is the far easier task. The Howard government lost office because its leader was old and tired; because the nation in general, and younger voters in particular, had stopped listening to the prime minister's attempts to excite baseless fears about minorities and foreigners; because a sufficient number of electors had finally realised that the prime minister's word could not be relied upon; because the government's credibility as a superior economic manager had been compromised by its incapacity to control interest rates, as it had rashly promised it could do in 2004; because on two of the great international issues of the day - global warming and the War on Terror - Howard's unseemly embrace of the worst president in the history of the United States had fatally undone his claims to statesmanship and wisdom; and because, above all, the control his government had gained in the Senate in July 2005 had tempted the prime minister to introduce one neo-liberal economic reform too many, the one for which he had spent his entire political career preparing, the grotesquely unbalanced and therefore very widely resented new workplace-relations law.

Well before the election, as the Howard government drifted to its inevitable defeat, the Right in Australia embarked upon a curious campaign, involving an attempt to provide an answer to the second question - the meaning of the coming Rudd victory - through the mounting of what is best described as an interpretative pre-emptive strike. To reveal the character of this campaign, one example, in which this magazine was involved, must suffice. It comes from the overwhelmingly most influential voice of the mainstream, neo-liberal and neo-conservative Right in this country, the Australian, a newspaper that manages to combine the ambition of an ideologically engaged small magazine; the reckless, take-no-prisoners, smart-aleck tone of an undergraduate publication; and the financial resources of an American-based global media empire.

In the September 2007 Monthly I wrote a commentary which made certain predictions about the likely outcome of a Labor victory. The purpose was to respond to the increasing frustration about Kevin Rudd that was being voiced on the Left at that time. As Rudd had committed to immediate ratification of the Kyoto Protocol, I argued that when Labor took power Australia would finally join the world on global warming. As Rudd spoke about the Iraq invasion as the worst US foreign-policy blunder since Vietnam and had pledged to withdraw Australian troops from this particular quagmire, I argued that with a Rudd victory the painful and embarrassing mini-era when Australia followed America with lamb-like loyalty would end. Rudd had been consistently critical of both the taming of the parliament's inquisitorial function and the politicisation of the public service under Howard. I argued for cautious optimism on both fronts. Because he had made education the centrepiece of his campaign, and because he was so self-evidently a true believer in the virtue of science, scholarship and learning, I argued that the appalling neglect of universities under Howard would most likely be reversed. Of all the members of the Labor front bench since the demise of Latham, only Kevin Rudd had responded to Howard's increasingly triumphalist claims to victory in the Culture War - for example, to Howard's speech on the occasion of Quadrant's fiftieth anniversary. For this reason, I argued that it was likely, in particular, that under his government the most egregious appointees to the key boards of cultural institutions would be gradually replaced; and, in general, that the sterile era when a prime minister treated the nation's critical intelligentsia as un-Australian traitors and showed conspicuous indifference to the work of the country's creative artists would also, most likely, now draw to an end. As Rudd had pledged to repeal the most draconian and unjust aspects of WorkChoices, I argued that under Labor, industrial relations would be softened and humanised. These predictions were neither heroic nor romantic. The evidence for each proposition was clear. If they could be criticised for anything, it was for stating the bleeding obvious.

This is not how the Australian saw things. On 27 October it published an editorial called "Daydreaming Left is in for a Big Surprise". According to this editorial, in Australia two elections were taking place. In the real world, "a centre-left challenger" was fighting for the middle ground against a "centre-right pragmatist". In the fantasy parallel universe of "the daydreaming Left", Rudd was "fighting to end 11 dark years of despotic rule by a scheming far-right cultural warrior". To prove the existence of this parallel universe, the only evidence cited, in some ways the only evidence available (for in the real world the Left was already muttering darkly about Kevin Rudd's ‘me-too' caution and conservatism) were the modest predictions I had made in the Monthly about the likely meaning of a Rudd victory.

The editorial was based on a series of falsifications which, even judged by the standards one has come to expect from the Australian, took me by surprise. By sleight-of-hand the editorial turned support for the Rudd decision to ratify Kyoto into an ambition to "transform the nation into a wind-powered, mung-bean-eating Arcadia", and the desire for a more independent Australian foreign policy within the frame of the American alliance into the hope to have Australia "withdraw from ANZUS". Those who regretted the Howard government's prosecution of the Culture War, as I did, became the kind of people who wanted to make "gay marriage compulsory", whatever that was supposed to mean. And those many people, like me, who hoped that a Rudd victory might help "restore morality to public life" were ridiculed as erstwhile communists who mistook Kevin Rudd for "Che Guevara" and who had not yet realised "that the use-by date on Das Kapital is well and truly passed." (I have been accused of many things in my life but never before of being a closet sympathiser of communism.) The Australian helpfully felt the need to point out that Rudd was a Christian conservative, simply ignoring the morally radical interpretation of the relevance of faith in politics Rudd had famously advanced in his Bonhoeffer essay in the October 2006 Monthly. It pointed out that his wife was a global businesswoman, somehow implying that this positioned not only her but also her husband at a great distance from anything that could be associated with the contemporary Left. Not only did the editorial argue that the major parties under Rudd had grown closer than at any time in Australian history, something that was at least arguably true; more deeply, it suggested that Rudd offered no substantial alternative to Howard of any kind. If anything, it argued at one point, Rudd was now outflanking Howard on the Right. Four weeks before the election, the Australian would make no prediction about the result. Yet there was one prediction it would confidently make. "The agenda of a Rudd government is likely to be much closer to the position advocated in the editorial columns of this newspaper than the outdated, soft-left manifesto supported by our broadsheet rivals."

The editorial was both revealing and characteristic of much right-wing response to the impending victory of Labor in the last months of 2007. On the surface it mocked, with its usual indifference to nuance and truth, all those foolish enough to believe Australia would be a substantially different and kinder country if Rudd Labor was elected. Just beneath the surface it revealed that a certain kind of panic was gripping the hearts of those members of the right-wing commentariat - those people whom Guy Rundle has christened the Power Intellectuals of the Howard Era - who now sensed that, in the absence of a friendly government with interests they could help promote and enemies of that government they could help target and destroy, their cultural power would gradually ebb away. Even if a Rudd government was indeed elected, through mounting what I have called a pre-emptive interpretative strike of the kind seen in the Australian's pre-election editorial line, the mainstream Right could at least console itself with the thought that even after Howard's removal nothing of significance would change.

Whether the Rudd government will change Australia substantially and whether that change will be unambiguously for the better is a more complicated matter than it might at first appear. In part it is complicated because all new governments are to some extent unknown quantities, even to themselves. In part it is complicated because, even without conscious dissembling, in the effort to take power, particularly in a conservative-populist era like our own, particularly when the government is led by a politician whose most outstanding capacity was conjuring fear, prudence requires that Oppositions do or say nothing that might unduly frighten the horses. And in part it is complicated because it is becoming increasingly likely that - unlike the Hawke government, which came to power near the end of a recession, but like the earlier Labor administrations of Whitlam, which was governing when the stagflation crisis hit, and even more so of Scullin, which took power on the eve of the Great Depression - the Rudd government will find itself governing in testing economic times. Nevertheless, there are good reasons not only to believe that with Rudd changes of substance will occur but also that they will make Australia a substantially better country.

The most important reason lies not in the policy arena but in the more fundamental field of core values. Even though it is true that John Howard had an almost carnal desire to take and hold on to power at almost any cost - the fatal flaw that led to the farcical events at the time of APEC, amusingly outlined by Paul Kelly in the Weekend Australian of 15 December, when Howard refused to honour his solemn pledge and resign when his party no longer wanted him, simply because he was frightened of appearing like a coward - it is a major misunderstanding to think of him as a mere pragmatist or opportunist. For John Howard was one of the most ideological prime ministers this country has ever seen, whose thought was basically shaped by the two great currents of the contemporary, and especially the English-speaking, Right: neo-liberalism, the powerful and coherent market-based faith, and its fellow-travelling twin, neo-conservatism, that remarkably influential but philosophically incoherent set of beliefs first formulated in the 1970s in anti-leftist intellectual circles of New York, which centred on the beneficence of American power, the ambition to spread democracy across the globe through the use of that power and on the dangers posed to the true and decent values of ordinary people in the West by politically correct, morally relativistic, self-hating elites. The place of ideology in Howard's thought has recently been acknowledged by the most powerful right-wing think-tank in the US, the American Enterprise Institute, which has decided to offer him its prestigious Irving Kristol Award.

Not only was the thought of John Howard shaped by an Australianised and banalised version of neo-liberalism and neo-conservatism. As with his spiritual soul mate, President George W Bush, Howard's commitment to this pattern of thinking must play a part in any explanation of his government's end. As Sir Nicholas Stern put it so well, global warming represents the greatest example of market failure in the history of humankind. At least in part because he was a true believer in neo-liberalism, Howard was notoriously incapable of rising to the challenge of global warming, which was made real to the Australian electorate with the arrival in the settled areas of the south-east of perhaps the most severe drought in the nation's history. And in very large part because he was a true believer in neo-conservatism, Howard committed Australia to the greatest folly of that cause, the invasion of Iraq, whose meaning was made evident to the voters through the daily television pictures of the terrorist bombings in Baghdad. As a consequence of his ideological commitment to neo-liberalism and neo-conservatism, then, Howard's reputation was in the end fatally undermined.

I must admit I would have voted for Labor in 2007 if it had been led by the drover's dog (or even by Bill Hayden). But in fact I voted Labor with enthusiasm and as a convinced Ruddite because of the two articles he published in the Monthly in October and November 2006. What these articles revealed was that, almost alone among the members of the Beazley front bench, Rudd saw the need to distinguish social-democratic Labor from the twin neo-liberal and neo-conservative philosophies of the Howard government.

Rudd put his finger on the central contradiction of the contemporary Western Right: simultaneous support for the revolutionary dynamic of an unbridled capitalist economy, and the ambition for the restoration, through the preaching of a doctrine of a moral conservatism, of an earlier social order based on religion, family and community. Rudd saw in Howard's new workplace-relations legislation a concretisation of this contradiction, in which a government committed to family values and family stability was simultaneously encouraging its members to see themselves as factors of production who would discover, through individual contracts made with their employers, the best terms and conditions they could achieve after bargaining in a free market for the sale of their labour. Under contemporary conditions, Rudd argued, the neo-liberal Right had only three foundational values: liberty, security and prosperity. Rudd proposed the need to add to them three additional values derived from the Christian socialist and social-democratic traditions: equity, community and sustainability. Rudd spoke about asylum seekers, the challenge of global poverty and of our generation's moral obligation to ensuring the wellbeing of the planet with a moral directness that we had not heard from a senior Labor figure since the fall of Keating. In answer to the market fundamentalism of the Right and their Hayekian suspicion about the place of altruism in the public sphere, he proposed a return to the wisdom of an earlier insight derived from politically engaged Christianity, as exemplified in the life and thought of his hero, Dietrich Bonhoeffer, namely the urgency of the insertion, in the centre of our political values, of the needs of the vulnerable, the marginal and the weak. No one prominent in Australian public life had spoken in this timbre since the time of Sir William Deane. When I first read Rudd's Bonhoeffer essay I could scarcely believe my eyes. I thought the ministers of the Howard government and the right-wing commentariat would proceed to tear him apart. Thankfully I was wrong.

There was a time when the visions about the future of this country of the then prime minister of Australia, Paul Keating, and the then editor-in-chief of the Australian, Paul Kelly, were so close that I mischievously described them as the most influential Irish-Australian double act in the history of the country. During the Howard years their visions drifted farther and farther apart. On the eve of the 2007 election, Kelly claimed that the Howard government had been extraordinarily successful in delivering unprecedented prosperity without undue inequality while, in the foreign-policy field, maintaining close relations with both the United States and Asia. His central claim was, in essence, that the Howard government had continued the work of its predecessors, under Hawke and Keating, in creating what Kelly labelled the new Australian settlement. The public intellectuals who could not understand this were fools. Keating's analysis could not have been more different. For him, in the mendacity that had pervaded the public sphere, even over questions as serious as the commitment to war; in the cruelty that had been witnessed in the treatment of the asylum seekers; and in the squandering of the opportunities to advance the great causes of multiculturalism, reconciliation and the republic, the Howard government had reversed the cultural trajectory of all Australian governments since the time of Whitlam and had undermined what he called "the moral basis to our public life". Readers will not be surprised to hear that it is Keating, not Kelly, whose summary I believe is right. In the short term, historians will provide answers to this question. In the long term, History will be the judge.

A generous moral vision does not make a government good. But without one, it cannot but be bad. For me, that has been the most important lesson of the Howard years. Although he is obviously a canny, cautious and highly ambitious politician, nothing that has happened in the past 18 months has led me to doubt that the basic Christian social-democratic convictions Kevin Rudd expressed in his articles of 2006 are not sincere. The vision Rudd expressed there was measured but generous. That is why I anticipate the next three years of Australian politics with some trepidation but also with rediscovered hope.

The Professional Cricketers Association FICA slams 'anti-competitive behaviour' over ICL

Tim May, the chief executive of FICA, the international players' association, has expressed his concern over attempts by national boards to impose bans on players who have signed for the unauthorised Indian Cricket League.

Making clear that FICA "neither supports nor rejects the ICL", May said that his organisation's primary aim "is to ensure that players rights are upheld and that governing bodies do not unreasonably restrain players from plying their trade".

He said players were only under an obligation to play exclusively for a body when they enter into a contract with them to that effect. "Where a player has chosen not to enter a contract with a particular governing body or alternatively has not been offered a contract the player should be free to play wherever he likes."

His comments come in the light of reported moves by the Pakistan and New Zealand boards to refuse to grant their players No Objection Certificates which are needed by them to play for English county sides. "What we are now seeing is that governing bodies are introducing a variety of measures that will limit the ability of players who play in the ICL being considered for competitions under the jurisdiction of those [boards].

"A governing body can devise its own qualification rules - it's whether they are unlawful or not, whether these will be acceptable to player associations. These are where the issues of unreasonable restraint of trade, discrimination and various anti-competitive behaviour arise."

May made it clear that "FICA and its player associations will defend the right of players to seek employment without fear of unreasonable restraint of trade, discrimination and the collusion of a number of bodies to monopolise employment and restrict movement in the market".

He said it remained unclear what the objection to the ICL is, "apart from it being an unwanted competitor. No governing body has yet satisfactorily explained to players' associations why ICL is such a danger to cricket. In any other walk of life, it's accepted that competitive markets are more desirable than monopolistic markets.

"We have heard public comments that ICL has the propensity to take a significant amount of the games' revenues away from the global revenue stream and that all countries will suffer accordingly. Incredibly the other countries just sat aside silently when the BCCI derived US$2 billion out of the games' potential revenues for the BCCI's exclusive use - which I presume was pretty much the same US$2 billion that ICL were suppose to suck out of the system.

"Countries have also objected to ICL revenues being diverted to private enterprise rather than the development of the game - they have conveniently cast a blind eye to the fact that a significant proportion of the ongoing profits of the 'official' IPL tournament will be distributed to private enterprises, not the game.

"I am staggered given cricket's significantly small number of professional cricketers that the creation of a further 60 or 70 professional positions is viewed as a negative for the game."

One argument put forward against the ICL is that it has no effective anti-doping policy. "Neither do half of the ten Test playing nations," May countered. "I don't hear countries saying they won't play other countries because they don't have anti-doping policies.

"For many, if not all, countries, the number of these players that will embrace IPL will only increase, as players are increasingly frustrated by low remuneration, lengthy absences from family and the direction and governance of our game. While all other sports are bending their backs to attract talent - cricket seems hell bent on ridding itself of its talent.

"The big question is ... what is more of a risk to the game. The ICL, or the policies being constructed by our governors?"
