What Hollande should do now

How the new French president can oblige the Germans to play their part in Europe's growth strategy.

Francois Hollande comes to power at an interesting conjuncture, with Europe in crisis and the political mood on the move. It is a shift of mood not just amongst the electorate - most of whom have long been opposed to austerity (all we saw last Sunday was their chance to express their views in elections) - but amongst the political class and the technocratic elites. Voices arguing that Europe needs a growth strategy as well as a fiscal consolidation strategy are finally emerging from the IMF, from the Presidents of the European Council and the European Commission, as well as from a growing number of European leaders.  Angela Merkel swept everyone before her when she demanded a new European Fiscal Compact only months ago, but today is beginning to look surprisingly isolated with calls for a re-think coming not just from Greece and France, but also from Belgium, Spain and Italy.

Politically, Hollande therefore has more potential clout than might initially appear. Despite this the reality remains that, financially, virtually all the economic power in Europe lies in German hands and, hardly surprisingly, the German Chancellor has rapidly stated that as far as she is concerned, austerity rules. At the same time Hollande can hardly go off on a spending spree of his own. The markets would pulverise him. 

What then can Hollande do?  Pre-election, he was hardly a radical on curbing the calls for deficit reduction, merely saying that France should go slower and have a further year to consolidate. But there is one significant other possibility. In consultation with like-minded colleagues, he should turn the discussion on its head and say to Germany: we fully support the need for fiscal consolidation, but, as good Europeans, we all expect equality of treatment. In particular, you will understand that 2+2 must equal 4 and so if there are to be no deficits there must be no surpluses either.

More precisely, he should direct attention to the current text of the Fiscal Pact. Title III, Article 3, sub-clause 1 (a) reads as follows:

the budgetary position of the general government of the Contracting Parties shall be balanced or in surplus*

*[emphasis added]

The removal of these last three words would make a fundamental difference. Not only is it the case that, economically, the removal of deficits will in any case require the removal of surpluses - but more importantly, it would place on Germany the obligation to play its part in financing the growth strategy without which such fiscal consolidation is impossible.

To underline his point, Hollande might add some history. The error in the current European Fiscal compact is identical to that made at Bretton Woods in 1944. That discussion was about balance of payments surpluses and deficits, but apart from this shift of focus, the problem is identical. Those at Bretton Woods insisted on countries acting to correct deficits but without placing a reciprocal obligation on surplus countries. There is still the widespread view that Bretton Woods worked smoothly from the start. It did not. It was massively breached by the UK in 1947, when as the Bretton Woods arrangements required, we liberalised capital flows - but then, against the rules, had to re-impose them virtually straight away to prevent a forced devaluation. The system was only saved when in 1948 the US launched Marshall Aid, a stimulus of a kind not even contemplated by the Bretton Woods agreement.

Reminding Germany of this history would be salutary; at least some of their current prosperity stems from how their post-war recovery was financed. And Hollande’s pressure in this direction can hardly be too uncomfortable for the German Chancellor. Asking for less taxation and more spending is not the most difficult of messages to deliver to a politician – even in Germany.

Inside Big Ben: why the world’s most famous clock will soon lose its bong

Every now and then, even the most famous of clocks need a bit of care.

London is soon going to lose one of its most familiar sounds when the world-famous Big Ben falls silent for repairs. The “bonging” chimes that have marked the passing of time for Londoners since 1859 will fall silent for months beginning in 2017 as part of a three-year £29m conservation project.

Of course, “Big Ben” is the nickname of the Great Bell and the bell itself is not in bad shape – even though it does have a huge crack in it.

The bell weighs nearly 14 tonnes and it cracked in 1859 when it was first bonged with a hammer that was way too heavy.

The crack was never repaired. Instead the bell was rotated one eighth of a turn and a lighter (200kg) hammer was installed. The cracked bell has a characteristic sound which we have all grown to love.

Big Ben strikes. UK Parliament.

Instead, it is the Elizabeth Tower (1859) and the clock mechanism (1854), designed by Denison and Airy, that need attention.

Any building or machine needs regular maintenance – we paint our doors and windows when they need it and we repair or replace our cars quite routinely. It is convenient to choose a day when we’re out of the house to paint the doors, or when we don’t need the car to repair the brakes. But a clock just doesn’t stop – especially not a clock as iconic as the Great Clock at the Palace of Westminster.

Repairs to the tower are long overdue. There is corrosion damage to the cast iron roof and to the belfry structure which keeps the bells in place. There is water damage to the masonry and condensation problems will be addressed, too. There are plumbing and electrical works to be done for a lift to be installed in one of the ventilation shafts, toilet facilities and the fitting of low-energy lighting.

Marvel of engineering

The clock mechanism itself is remarkable. In its 162-year history it has only had one major breakdown. In 1976 the speed regulator for the chimes broke and the mechanism sped up to destruction. The resulting damage took months to repair.

The weights that drive the clock are, like the bells and hammers, unimaginably huge. The “drive train” that keeps the pendulum swinging and that turns the hands is driven by a weight of about 100kg. Two other weights that ring the bells are each over a tonne. If any of these weights falls out of control (as in the 1976 incident), they could do a lot of damage.

The pendulum suspension spring is especially critical because it holds up the huge pendulum bob which weighs 321kg. The swinging pendulum releases the “escapement” every two seconds which then turns the hands on the clock’s four faces. If you look very closely, you will see that the minute hand doesn’t move smoothly but it sits still most of the time, only moving on each tick by 1.5cm.

The pendulum swings back and forth 21,600 times a day. That’s nearly 8m times a year, bending the pendulum spring. Like any metal, it has the potential to suffer from fatigue. The pendulum needs to be lifted out of the clock so that the spring can be closely inspected.

The clock derives its remarkable accuracy in part from the temperature compensation which is built into the construction of the pendulum. This was yet another of John Harrison’s genius ideas (you probably know him from longitude fame). He came up with the solution of using metals of differing temperature expansion coefficient so that the pendulum doesn’t change in length as the temperature changes with the seasons.

In the Westminster clock, the pendulum shaft is made of concentric tubes of steel and zinc. A similar construction is described for the clock in Trinity College Cambridge and near perfect temperature compensation can be achieved. But zinc is a ductile metal and the tube deforms with time under the heavy load of the 321kg pendulum bob. This “creeping” will cause the temperature compensation to jam up and become less effective.

So stopping the clock will also be a good opportunity to dismantle the pendulum completely and to check that the zinc tube is sliding freely. This in itself is a few days' work.

What makes it tick

But the truly clever bit of this clock is the escapement. All clocks have one - it’s what makes the clock tick, quite literally. Denison developed his new gravity escapement especially for the Westminster clock. It decouples the driving force of the falling weight from the periodic force that maintains the motion of the pendulum. To this day, the best tower clocks in England use the gravity escapement leading to remarkable accuracy – better even than that of your quartz crystal wrist watch.

In Denison’s gravity escapement, the “tick” is the impact of the “legs” of the escapement colliding with hardened steel seats. Each collision causes microscopic damage which, accumulated over millions of collisions per year, causes wear and tear affecting the accuracy of the clock. It is impossible to inspect the escapement without stopping the clock. Part of the maintenance proposed during this stoppage is a thorough overhaul of the escapement and the other workings of the clock.

The Westminster clock is a remarkable icon for London and for England. For more than 150 years it has reminded us of each hour, tirelessly. That’s what I love about clocks – they seem to carry on without a fuss. But every now and then even the most famous of clocks need a bit of care. After this period of pampering, “Big Ben” ought to be set for another 100 or so years of trouble-free running.
