Solar power hope for P&O


mv-european-highlander-1

Peninsular and Oriental Ferries (P&O) have made large strides towards minimising their carbon footprint, but how soon can we expect solar powered ferries. Murali Podila investigates.

The company is aiming for a low emissions target based on factors such as tides, currents, and wind and wave conditions – a key definer of the amount of fuel used in ferries.

P&O has equipped one of its ferries with scrubbers to remove dangerous sulphur dioxide gases which produce acid rain. These scrubbers have earned the company international acclaim and spurred on hopes for a solar power driven ferry.

Perhaps one day ferries will be entirely powered by solar energy. First, however, some issues must be addressed. To run a ferry on batteries for an extended period of time, or power a full deck of cars and passengers with the sun, would be immensely pricey, not to mention unreliable due to weather conditions.

In the future P&O may decide to use large solar panels, which can act as sails, transforming sunlight into enough energy to power a ferry. Similar innovative designs are already in place around the world.

Alcatraz Cruises, a tourist company in America, has designed a hybrid vessel system which adapts to its surrounding conditions, efficiently gathering energy during sunny days and using a motor during rough weather. The Solar Sailor in Sydney harbour is similarly designed for efficiency, gathering energy from both wind and solar activity.

Energy produced in overcast conditions is only around a fifth of what sunlight can produce through solar panels, which, unfortunately, already generate only small amounts of usable energy. Gathering sufficient amounts of energy from the sun to move a ferry may, for now, sadly only be a romantic dream.

The English Channel (‘La Manche’)


Moonrise over La Manche by Dimitry B

Without the English Channel we would all be in a good deal of trouble. In the spirit of appreciation, Peter Moore jots down some of its vital statistics. Additional research by Murali Podila

The Silvery English Sea

‘The Channel is that silver strip of sea which severs merry England for the tardy realms of Europe’, wrote an anonymous author in the Church and State Review, on 1 April, 1863.

The author’s reverence was well-founded. The Channel did for Napoleon Bonaparte, who regarded it as little more than a dirty ditch, and it did with similar efficiency for the steel and frightful force of Adolf Hitler’s panzer division in 1940.

These are just the tip of the iceberg. All told, the English Channel has been helping us fend off nasty continental types since the days of Stonehenge, jugs of mead, King Arthur, burnt cakes, round tables and Merlin’s beard. And with this in mind, I’ve decided that it is high time for a statistic appreciation of the silvery strait. After all, it is one of the most formidable geographic barriers in history.

The English Channel: Statbox.

—  The start point, the furthest to the West, is generally considered to be at the Scilly Islands and Ushant. The end point, the Eastern end of the channel, is the Strait of Dover is between Dover and Calais.

— Its length is about 350 miles long, but its width varies from 150 miles to 17 miles.

— It’s area is about 29,000 square miles (or 75,000 square kilometres)

— The channel narrows from 112 miles to only 17 miles, going from west to east.

— The widest part of the channel is about 150 miles, between Lyme Bay and St.Malo. The narrowest part is at about 17miles between Cap Gris Nez and Dover.

— The width of the Strait of Dover, where a lot of ferries operate, is 21 miles.

— The deepest point, at Hurds Deep, is at 180m. It’s shallowest at the Strait of Dover at about 45m.

— The English channels is quite densely populated on both shores with significant port towns and cities on either side of the shore such as:

Portsmouth (population of 360,000)
Bournemouth ( 383,713)
Southampton (304,400)
Le Harve (248,547)
Calais (104,852)

— The first known person to swim across the channel (Dover to Calais) was Matthew Webb, he completed it in 21hr 45min.

— The fastest person to swim across the channel was Petar Stoychev from Bulgaria; he did it in 6hr 57min.

— The oldest person to swim across the channel was George Burnstad who swam across the channel at the age of 70 years and 4 days.

— The youngest person to swim the channel is Thomas Gregory who swam across the channel at the age of 11 years and 11 months.

— By the end of 2005, 811 individuals had swam across the channel a total of 1185 times

— The person who has crossed the channel the most times is Alison Street MBE, who has swam across the channel 43 times.

— The first crossing by air was on the 7th January 1785 by Jean-Pierre Blanchard and John Jefferies. This was done by using a balloon.

— The first passenger ferry crossed the channel on the 10 June 1821, now there is a ferry going from Dover to Calais almost every 45 minutes for most of the day!

— The first aircraft flight with passengers was made in 23 August 1910 carrying the pilots’ cat and the mechanic.

— The surface temperature ranges from 7°C in February to 16°C in September.

— The temperature of the water does change with depth on the well mixed waters in the eastern side of the channel. But the temperature drops to about 5°C in the eastern side of the channel.

— The overall climate changes a lot and is dependent on cloud cover and wind. The temperatures generally vary from -5°C to 12°C in the winter to about 20°C to 30°C in the summer.

Killer tomatoes never looked so good


La Tomatina

Never play with your food? Pavla Tolonen finds a place where you can.

Tonnes of over-ripe tomatoes, thirty degrees scorching heat and a town filled with adorably mad people ready to pellet each other into tomato juice oblivion – welcome to late-August Buñol in Valencia.

This 57-year-old tradition (officially) originally comprised only of the local folk but now attracts over 20,000 tourists a year, raking in well-deserved capital for the later tomato-drenched town of around 9,000 permanent inhabitants.

The event kicks off at 10am on the third Wednesday of every August with a public gathering to resolve the mystery of how to bring down a ham on a greased pole. After they successfully lower the ham, the council-funded tomatoes are released on to the town square, Plaza del Pueblo. The crowd bursts into song and dance, while being hosed down by friendly showers.

The start signal is by water cannon, after which the tomato bombardments last for around an hour or more. Part-takers are advised to squish the fruit before throwing and wear protective goggles and gloves. Flip-flops and cameras (except Aquatic cameras) are best left at home. Once the second water cannon is fired the festival is over, and the streets and the crowd can be hosed down.

Horrified tomato-lovers will be relieved to know that the tomatoes are not suitable for consumption as they taste bad. They come from Extremadura, in western Spain, where tomatoes are cheaper and especially grown for this event.

Naughty behaviour aside, the festival commemorates the legacy of St. Louis Bertrand (San Luis Bertràn), the patron saint of Buñol, and the Virgin Mary, or Mother of God of the Defenseless (Mare de Déu dels Desemparats), as they call her.

The origins of the event remain uncovered, but popular myths include a story of angry villagers attacking city councilmen at a public celebration. The event was banned under the dictatorship of Francisco Franco, but was reinstated with full flare after his demise.
