The moon landing: 40 years on


As it's forty years since man first landed on the moon, I've trawled through the Speccie archives to see what we wrote about the event at the time. There's one feature article in the issue dated 26 July, 1969, which I've reprinted below. Oddly, the landing isn't mentioned on the magazine's cover - and nor is it the topic of that week's leader - but old hands around the office assure me that could have been a result of arcane printing practices, which saw the cover go to print days before the rest of the magazine. Still, the article the magazine did contain is a neat tribute to human ingenuity and daring. Here it is:

The Americans are simply an amazing people. If the qualities that the British pride themselves on show best under strain, then the qualities of Americans are most clear under the light of success. The last ten days in this country have been a strange time. But many of the personal and collective qualities that have made America what it is have been uncloaked by the simple but brilliant success of the Apollo 11 flight. And they make it easy o forget for a time the bad things and concentrate on the good.

There is first the technological power of this country, that so astonished Khrushchev on his visit , and that has magnified almost beyond recognition even in the intervening few years. The Americans have just completed an enterprise of greater technological complexity than anything tried before. They conducted the entire operation in the fullest publicity they could manage, and they brought it off with scarcely a hitch. There is a tendency to gloss over the sheer mechanics of a flight to the moon - the mathematics, the chemistry, the physics, and so on - as old hat. But for those who like myself can hardly build a card-house of more than two or three stories without developing insuperable mechanical problems, it is worth continually reminding ourselves that the machinery that put two Americans on the moon had literally millions of moving parts.

That this machinery worked so well is not only a tribute to the ingenuity of the men who built it, but a comforting proof that man can remain in charge of the machines he builds. The cybernetics of Apollo 11, the logistic equations, the critical path analyses… all these were about as far from the quadratic equations of our youth as the rockets Wernher von Braun made in his youth were from Saturn 5. But the end result of this vast system was to enable two men to go and dance on the moon.

Controlling the technical creations of the cleverest nation of scientists were two of the most admirable human qualities: confidence and modesty. It may sound odd to talk of Americans and modesty in the same sentence, but really there has been very little boasting this week. There has been a lot of congratulation, naturally, but almost no gloating. There was even, before the flight, a considerable debate about whether the Stars and Stripes should be planted on the moon; a lot of people thought nothing so narrow should mark man’s first extraterrestrial visit, and that a United Nations flag would be more appropriate. That such a debate should even be started is to me astonishing: can anyone doubt that if the first men to go to the moon had come from another country, say England or France or Ghana, they would have taken their country’s flag? One dinner-party guest said to me on Saturday: ‘You know, if you had been the ones to get there first, your astronaut would have planted the Union Jack and said: “I name this moon Elizabeth.” ’

The confidence was equally striking. Everyone knew that the mission was dangerous. No one had ever done it before, and even if all foreseeable dangers were anticipated, there was always the a priori argument that since the moon is an alien world man’s powers of perception and detection, however great, just might not be of the type to detect the dangers. And yet, in the weeks that led up to the launch, and the days of the flight, scarcely anyone betrayed that he believed all would not go well. The whole business was shrugged off with that coolness, that matter-of-factness, which Americans claim is the British characteristic they most admire.

It was in the spirit of the great adventurers… the ‘Doctor Livingstone, I presume?’ ploy. This is to me the first and strongest impression of Americans, that they are the adventurers of the world. They started that way, they have continued that way. They pride themselves on it, and it doesn’t look as if anything will stop them. Sometimes their adventures end in tragic futility, as in Vietnam and Cuba; sometimes they end in glory. But their reach will always exceed their grasp, and now that they have grasped the moon, they will reach for something else. This, the underlying romance of humanity, is in permanent conflict with the practical side of their nature.

For they are a supremely practical people. They want to know whether something can be done and what it will cost, and if possible what use it will be. Vague answers to these questions will not stop them trying a particular enterprise, but will provoke a wall of criticism. The space programme, and especially the moon programme has been clear enough in the last few years, when there were, plain for the world to see, colossal problems in the United States itself, which could have used the $25,000 million that moon programme has cost. To this criticism, the best answer has been given, a long time ago, by Benjamin Franklin, who was at the time ambassador to Paris. One of the earliest balloon experiments was in process, when he was asked: ‘What is the use of a balloon?’ He replied: ‘And what use, sir, is a new-born babe?’

The use is because it is there; the reason for doing so is because it is there. Mankind has come a long way since a poor Greek scientist was clapped in irons for daring to suggest that the sun might be as big as the Peloponnese.

Now, the moon is as big as Apollo. We have gone on doing things and going places simply because they were there. And if you are at a loss for words to describe what has happened, you are in the company of the poet:

‘And I am dumb to tell a weather’s wind
How time has ticked a heaven round the stars.’

In space at least, the Americans are the Greeks of today. They have the two great characteristics of the Athenians, acquisitiveness and inquisitiveness. They love to find practical uses for their knowledge, but they also love knowledge for its own sake. Like Ulysses, they journey and they fight.

And like Ulysses, they are not good at sitting still:

‘I am a part of all that I have met;
Yet all experience is an arch wherethrough
Gleams that untravelled world, whose margin fades
For ever and for ever when I move.
How dull it is to pause, to make an end,
To rust unburnish’d not to shine in use.’

It would be a shame if the domestic pressure in America now forced a decline the exploration of space. There is a spirit, ‘yearning in desire to follow knowledge, like a sinking star, beyond, the utmost bound of human thought.’ This spirit must be served, or mankind will be the less.

Croke Park dug up for U2 as Pussycat Dolls take over Fitzgerald Stadium


WITHIN an hour of Dublin beating Kildare in a pulsating Leinster football championship final at Croke Park yesterday, a convoy of heavy machinery had moved in to begin digging up the pitch surface to accommodate the three U2 concerts that will be held there next weekend.

The last of the 74,563 crowd were making their way out of the stadium as earth movers and dumping trucks commenced pulling up the surface. The main body of work is expected to be completed by tomorrow.

GAA officials are confident that, once the concerts have concluded, the ground staff will have plenty of time to ensure that the playing surface is in tip-top condition for the All football championship quarter-finals on the August Bank Holiday weekend.

Killarney's Fitzgerald Stadium is also in the news for musical reasons. It has been ruled out for Kerry's third-round qualifier against because the all-girl American group, are performing there on Saturday night. has been nominated as the alternative venue and Kerry have requested an afternoon throw-in.

Fearing Failure, China May Nix Hummer Deal

when a little-known Chinese company agreed to purchase Hummer from General Motors in June, the deal was initially seen as another symbol of a rising China's might. But recent murmurs from Beijing suggest that authorities might nix the acquisition by Sichuan Tengzhong Heavy Industrial Machinery; state media are reporting that Hummer's environment-crushing reputation doesn't fit with China's new drive to go green. Yet environmental concerns are just a public excuse. According to officials, Beijing's real worries are much more hard-nosed: Should Tengzhong fail to restructure the ailing SUV maker, it would damage China's image in the international marketplace. And Beijing has good reason to believe some of its domestic auto companies aren't ready to drive a foreign brand. The eager buyer is unknown even in China, and its expertise lies mainly in dump trucks and cement mixers. The past is sobering: when China's biggest carmaker, SAIC, bought a stake in South Korea's Ssangyong Motor Co. in 2004, it ran afoul of Korean labor unions, which obstructed the hoped-for turnaround. Foreign assets are "hard to digest," says Eduardo Morcillo, an M&A expert with InterChina Consulting. Still, Ssangyong was barely known outside Asia. Failing with an international brand like Hummer would cause far sharper stomach pains.

Slow, Costly and Often Dangerous Road to Wind Power


rucks carrying silvery blades nearly half a football field long have been lumbering through this placid coastal town all summer, backing up traffic as they slowly exit the roadway. Huge, tubular chunks of tower also pass through. Tall pieces of machinery looking somewhat like jet engines travel at night because they require special routing to avoid overpasses.As demand for clean energy grows, towns around the country are finding their traffic patterns roiled as convoys carrying disassembled towers that will reach more than 250 feet in height, as well as motors, blades and other parts roll through. Escorted by patrol cars and gawked at by pedestrians,

Plenty can go wrong despite months of planning. In Idaho and Texas, trucks laden with tall turbine parts have slammed into interstate overpasses, requiring hundreds of thousands of dollars in repairs. In Minnesota last year, a truck carrying a tubular tower section got stuck at a railroad crossing; an approaching train stopped just in time. Also in Minnesota, a woman was killed last September when her car, driven by her husband, collided at an intersection with a truck carrying a wind turbine. (After a police investigation, local officials found that the truck driver was not at fault.)

Maine had a glitch of its own two years ago, after a truck carrying a big piece of turbine got stuck for hours while trying to round a corner near Searsport, a port near Belfast that receives many turbine parts from overseas.

In Belfast, the onslaught of turbine-toting trucks did not receive a warm welcome at first from some local business owners, who feared that rerouting traffic during the summer tourist season — the best time to transport turbines in a wintry state like Maine — would keep patrons away.

“We were afraid that the state was going to put up signs to avoid Belfast because of the delays,” said Jerry Savitz, the owner of Darby’s Restaurant in Belfast, who added that locals nonetheless supported the idea of windmills because of the clean energy they create.

After discussions with the town, the wind developers agreed to send the tall nacelles, which sit at the top of the turbine towers and contain the electrical generating components, through town at night, so few people would be delayed. Because they had to pass through residential neighborhoods to avoid low underpasses, residents feared that a few trees would need to be chopped down. But in the end, the trees were spared.

There is talk of breaking a blade up into multiple pieces, but “that’s a very significant structural concern,” said Mr. Stricker, who also noted that tower bases were getting too large to squeeze through underpasses.

In Texas, the state with by far the most wind turbines, the constant truck traffic has created another challenge: it is tearing up small roads in the western part of the state, where the turbines are being rapidly erected.

“You get what we call alligator cracking,” said Stacey Young, a pavement engineer for the Lubbock district of the Texas Department of Transportation, referring to small seams in the pavement.

One paved road in her area is “basically a gravel road now” because of the trucks going through, Ms. Young said. She has appealed to state lawmakers to require the developers to help pay for the upkeep of the roads, but so far to no avail.

A partial solution for Ms. Young’s concerns may be at hand. The vast majority of turbine parts travel by truck, but in Texas and elsewhere, some wind companies are looking to move more turbine parts by train to save money. General Electric, a big turbine maker, says rail transport can be up to 50 percent cheaper over long distances, and the rail company Union Pacific saw its wind-related shipments more than double last year.

Armory getting concrete parking for heavy machinery


Heavy machinery such as construction equipment and tanks are coming to the Keokuk National Guard Armory when a $323,000 project is completed around Labor Day.

A 70-by-85-foot section of the parking area behind the armory is getting an eight-inch concrete surface to handle the heavy machinery, according to Curtis Grant, project manager for First Construction Group, Inc. of Burlington, the general contractor. Another 100-by-40-foot portion of the parking lot will have a rock surface.

In addition, a 30-foot-long, 28-foot-wide concrete ramp is being built to load and unload the heavy machinery, Grant said.
The machinery is stored now at the National Guard Armory in Mount Pleasant, which also is scheduled to get a parking lot upgrade. No bids have been let yet on the Mount Pleasant project. Once the Keokuk armory project is finished, the National Guard will be able to store heavy machinery at each location, Grant pointed out.

A trench drain also is being installed near the metal maintenance vehicle storage building behind the Keokuk armory to handle water coming off the building’s roof and the improved parking lot.

Five trees were removed during the work in Keokuk, and they will be replaced with five new blue spruce trees or some other variety, Grant said.

Kemppi FitWeld 300 MIG/MAG


The Kemppi FitWeld 300 MIG/MAG, a machine that the company said is designed to save input power compared with MMA tack welding in heavy equipment manufacturing.

The three-phase 400V 50/60Hz machine is rated 300A at 20 per cent duty cycle, has a 43V open circuit voltage, and can be used with mild steel solid and flux cored wires as well as stainless steel and aluminium wires from 0.8 – 1.2mm.

Features of the Kemppi FitWeld 300 include the QuickArc clean arc ignition, which produces minimum spatter and fast arc stabilisation.

The GT WireDrive gives a rapid response to welding gun trigger signals, as well as for multiple-arc start use.

The GasGuard automatically prevents welding when shielding gas is not present or is accidentally disconnected for the machine.

Brights in-built lighting provides welders with a cool white light to make wire spool changes and parameter adjustments easier and safer in low-light working conditions.

Other features include a control panel for setting voltage and wire speed arc parameters, 2T and 4T gun switch selection, strong grab handles, enclosed wire spool holder, shielding gas flow adjustment, and easy polarity change, which allows positive or negative welding.

Two wildfires in western Canada near full containment

VANCOUVER, July 22 (Xinhua) -- Two wildfires in Kelowna area in Canada's western British Columbia province are close to full containment Wednesday, while a third one continuing to grow, according to fire officials.

The two massive wildfires in Glenrosa and Rose Valley are 80 percent under control and are expected to be fully contained later Wednesday, but it will be some time before they are extinguished, said fire officials.

Jason Johnson, the Emergency Operations Center Director said: "It has been a difficult few days and the emergency isn't over, but the news that the Glenrosa and Rose Valley fires are close to full containment is most welcome."

Local media reported that firefighters fighting the Glenrosa fire, estimated at 300 hectares, were working to create a fuel-free barrier on the southern flank of the fire. Fire crews at the Rose

Valley were working with heavy equipment and supported by helicopter bucketing to contain the fire, estimated at 100 hectares.

With the firefighters gaining upper hand over the fires, nearly half of 11,000 evacuees who were forced to flee West Kelowna because of forest fires were allowed to return home Tuesday, and fire officials said the remaining are expected to return late Wednesday afternoon. But they will remain under an evacuation alert, which means they have to be ready to leave at a moment's notice.

Many returning residents felt relieved when they saw their houses standing there but some were surprised to find their evacuated homes had been visited by thieves who took advantage of the situation.

Resident Barbare Kreibom told Canadian Broadcasting Corporation Wednesday that she was "shocked" to find her son's gaming system and skateboard stolen. Although she felt "violated," she said some people lost much more to looters.

Cpl. Dan Moskaluk of Royal Canadian Mounted Police said police had received at least 10 confirmed reports of break-and-enters from the evacuated homes in Glenrosa, and appealed to returning residents to keep an eye out for clues about criminal activity around their property.

As of Wednesday noon, the wildfire burning at Terrace Mountain has swelled in size to about 2,000 hectares from about 1,800 hectares one day earlier. The B.C. Forest Service is aggressively battling this fire with 175 firefighters on the ground, with seven helicopters and heavy machinery continuing to build guards around the fire's perimeter. This fire is estimated to be 30 percent contained.

Though there is no structure immediately threatened by this fire, authorities issued a new evacuation order affecting 10 properties and 13 people north of Kelowna, local media reported. Besides, an evacuation alert has been placed for approximately 2,200 residents and property owners living in several communities.

The three fires blazing across West Kelowna started Saturday afternoon and were spreading rapidly within hours. They are believed to be caused by people and an investigation team is conducting an examination into the fires' causes.

Of the total 2,024 fires that happened in British Columbia in 2008, 41.8 percent were human-caused, according to figures from the B.C. Forest Service.
