So went the Rolls Royce car ads years ago, back when Rolls actively marketed cars in the US. They used to do TV ads for Rolls. Haven't seen one for 30 years.
Actually, Rolls Royce sold off the car operation and makes its money on jet engines. And they are in trouble now. Aviation Week has a writeup on the catastrophic engine failure on the Quantas A380. Apparently the intermediate speed turbine failed, and flung turbine buckets out thru the engine casing, punching holes in the wing, a fuel tank and damaging hydraulic lines. Engine failure doesn't get worse than this.
Even worse, the Quantas engine failure looks to be related to the engine failure on Boeing's 787 program. Rolls-Royce may be in for an expensive recall and redesign.
Other problems showed up. The crew attempted to shut down the blown engine by closing a fuel valve. The digital engine control would not let them, it was programmed to keep the valve open in flight, lest the engine shut down for lack of fuel. Microprocessors can be really stupid sometimes.
Jet engine design is always a compromise between stoutness and lightness. The engine has to contain enormous forces and extreme temperatures. This calls for stout. To save on fuel, the engine wants to be as light as possible. Lightness reduces stoutness. It could be that the Rolls designers went too far in the lightness direction. This might be hard to fix, short of a complete redo.
What's worse for Rolls, is the A380 and the 787 can accept American engines and the airplane customer can order the planes with Rolls engines or American engines. Guess which engine maker is not going to be specified on future airliner orders?

Glen Beck needs a sense of humor
Watching Glen this evening. He was getting all bent out of shape about the press coverage that Prince William's and Kate Middleton's engagement were getting. He did a small rant about the media covering trivia.
Well Glen, in principle you are right. But, the Brits do such marvelous weddings and coronations. I enjoy the h**l out of them, every one. They are good fun and nobody gets hurt. What's not to like?

The internet is NOT secure, Anyone knows that.
Anyone except the TV newsies that is. Big story running today about internet traffic being diverted thru servers in China. Oh the horror.
Note to newsies, the public internet is PUBLIC, and anyone in the world can see the traffic. It's the World Wide Web. Putting anything on the web is same as posting it on the bulletin board down at your town supermarket. If you don't want to share it with the world. don't put it on the web. This goes for email, Facebook, Google, and just plain web cruising. If you don't want the whole world, including your employer, the IRS, and every noisy neighbor in the world to know, don't but it on the net.

What goes around, comes around
Obama comes home from Korea with a bit of egg on his face. He wanted to sign a Korea America free trade pact, but he wanted a few last minute changes and the Koreans balked.
Chickens are coming home to roost. George Bush negotiated the Korea free trade agreement back in 2007. But in 2007 the US Senate, of which Obama was a member, refused to ratify the agreement. Unions objected and the democrats caved to them.
Now, three years later, Obama wants to ratify Bush's old agreement, but with a couple of last minute changes that the Koreans didn't like. So, Obama comes home with bupkis.
What's worse, the original agreement, which the Koreans would have signed, is quite favorable to US automakers. It liberalized the Korean auto emissions standards to allow US built cars, that met US emissions standards, to be sold in Korea. The "minor change" Obama wanted, was a retention of a 2% US tariff on Korean cars. The Koreans are selling lots of cars with the 2% tariff, and/or building their cars in Kentucky, and the 2% tariff makes little difference in the number of Hyundai's sold here in competition with Government Motors.
For this insignificant tariff, Obama gave up a real opening of the Korean auto market to us. There are plenty of Koreans with money who would love to own a real Detroit car, say Corvette, or Cadillac, or Ford Explorer, just like they see in the movies. Right now such cars cannot be imported to Korean because of emissions laws. The Koreans were willing to essentially waive their emissions standards and allow Detroit iron in. And Obama didn't understand how important this is.
Stupidity can be embarrassing.

No pain spending reductions
Newt Gengrich on NBC this morning said the he and Clinton had balanced the US budget for years without inflicting enormous pain upon the voters. Today, the Democrats (progressive tax and spenders, all of 'em) protest that Federal spending reductions just can't be done because of the pain involved.
I think Newt is onto something here. Just reducing health care spending from 19% of GNP to 9.5% of GNP (a feat every other country in the world has managed) would free up a river of money that would solve the deficit problem.
Could it be that the Democrats are attempting to keep their tax and spend policies in place by predicting intense pain if they are not continued?

Northern Pass, Power to the People,
The Northern Pass project will run a new high voltage power line down from Quebec to Franklin NH. It will bring in 1200 Megawatts of clean Canadian hydropower to New Hampshire. Quebec has a vast surplus of hydropower which they have been exporting to the US for better than 50 years. Hydropower is a green as it gets, no CO2 emissions, no coal mines, no oil spills, no nuclear waste, freedom from fuel price hikes. Long as it keeps raining, we have juice.
To bring jobs to the North Country we need to offer reliable and low cost electricity to industry. No company is going to put in a plant without good electric service at a reasonable price.
The new power line will largely follow existing power line rights-of-way which mitigates the unsightliness. Big power lines are an eyesore, but adding a second set of towers side-by-side with an existing power line doesn't make much difference. A pair of side-by-side power lines is no more unsightly than a single line. We already have the single line, making it a double line doesn't change things much.
After much advocacy from anti-electric-power advocacy groups, the National Institutes of Health published a comprehensive study of the safety of electric power lines in 1999. The furor over power line electromagnetic fields was started in 1979 with the publication of a report linking leukemia to power line exposure. This study was inconclusive, and the effect reported was small. Numerous follow up studies failed to resolve the matter one way or another. Some studies showed no effect, some showed a small effect, and many showed different results depending upon the method used to measure intensity of the electromagnetic fields. These studies were all statistical, counting the number of cases of leukemia and using statistics to decide if the number of cases was abnormally high. Mark Twain once said there are lies, damned lies, and then statistics.
No laboratory experiments on animals has ever shown adverse effects from the electromagnetic fields around power lines. The science of physics and of chemistry shows no mechanism by which electromagnetic fields could alter the biology of humans or animals. The NIH report concludes that the risk from power line fields is unproven, probably non existent, but cannot be totally discarded because of those few statistical results.
Electromagnetic fields drop off rapidly with distance. A simple calculation shows the fields from your house wiring are as strong as the fields from a power line at the edge of the cleared right of way. So, even if there were some adverse effects, just keeping off the right of way keeps you safe.
So, in view of the great economic benefits (1300 construction jobs, $2.5 million/mile added to the tax base), the savings in fossil fuels, and carbon emissions, the Northern Pass project ought to go ahead. We need the jobs, we need the juice, and it's as green a project as there is.

Carnivale Cruise Lines
I gotta wonder how that Carnivale liner lost all power from an engine room fire. Did they have sprinklers in the engine room? Why does not a ship of that size have two engine rooms? Both with sprinklers.
We should be thankful that no one was hurt.
