Mossad Accused of Slowing Iranian Nuclear Program

Bruce has posted several stories about Stuxnet lately. Four days ago, for example, he pointed to a story in the news:

This long New York Times article includes some interesting revelations.

Buried in the comments you will find my short history of the CIA’s Operation Ajax in 1953:

I’d say this is all well documented history, but I also agree it is worth keeping in mind when we consider today why anyone would bother to destabilize Iran’s nuclear projects.

…and when I say destabilize, I mean trying to kill scientists, professors and their spouses. Stuxnet is a nice side-story to build a cyberwar budget, but I think in the big scheme of risk to international relations the five recent assassinations (and Ali Reza Asgari’s disappearance in 2007) should be getting far more attention.

“each car was approached by a group of men on motorcycles, who attached explosives to the vehicles and detonated them seconds later”

My point was that Stuxnet, which had minor effect, is really not that scary compared to the list of assassinations happening in clear violation of international laws. Yet Stuxnet seems to get all the news, perhaps because of its novelty compared to motorcycle bombs. That same day, little did I realize, Der Spiegel was posting a detailed look at the assassinations, assigning responsibility to Mossad in a story called “Israel’s Shadowy War on Iran: Mossad Zeros in on Tehran’s Nuclear Program

Israel’s leaders have always worried about the possible physical annihilation of their country, and it is this perceived threat that has formed their justification for the policy of assassination, even though it constitutes a breach of international law and the sovereignty of other nations.

…the death of Iranian nuclear scientists has slowed the development of the nuclear program and sowed fear among their colleagues, many of whom subsequently failed to turn up for work on the following days.

Addicted to Risk

Naomi Klein, author of “The Shock Doctrine”, asks in her TED presentation “What makes our culture so prone to the reckless high-stakes gamble, and why are women so frequently called upon to clean up the mess?”

One thing that comes to mind when I watched this was how President Bush signed an executive order on July 14, 2008, just before the end of his term, to lift the moratorium on offshore drilling in the eastern Gulf of Mexico and off the Atlantic and Pacific coasts. The moratorium was put in place in 1990 by his father. A year earlier President Bush lifted the moratorium from drilling in Alaska, also put in place by his father.

I thought the risk policy differences, between these two men, would have been at least mentioned.

Jaguar XJ Supersport Diesel Quicker Than Gasoline

The XJ Supersport is a diesel? It’s fast. Very fast.

The 4.4 liter diesel engine will deliver a total of 375bhp and a peak torque of more than 600lb.-ft. The sprint from 0 to 60 mph will be made quicker than the supercharged XJ and will return 40mpg. Same engine is also rumored to be offered in the Jaguar XF.

It hits 60 in 4.7 seconds, only 0.01 of a second behind the Jaguar XKR sports car. Oh, that 40 mpg figure actually drops to 24 mpg in the Supersport, but it’s still impressive for a sports car today.

It also has a high-tech interior. The dashboard is a dynamically changing TFT flat-screen panel, as described in a CNET review.

All the graphics shown there are dynamic and context-sensitive, so the visuals change, depending on what the driver requires. Receive new directions from the sat-nav, for example, and the fuel gauge is temporarily replaced by a full-colour map showing new directions. Access the engine computer and the rev counter is swapped for a colour menu that gives you access to vehicle setup functions.

It’s so fast, despite being fuel efficient, the police even have a model. Actually, the police model gets the smaller 40mpg engine but it still runs under 6 seconds to 60:

The Jaguar XF Diesel S is powered by a 3.0-liter AJ-V6D Gen III diesel engine that delivers 275 hp. The Diesel S accelerates from 0-60mph in just 5.9 seconds, while top speed is limited to 155 mph.

Send Ford an email and tell them to take the lessons learned from Jaguar and offer diesel options in America. What are they waiting for?

Harnessing the Danger of Lake Kivu

It sounds like a race against time, to capture the methane gas bubbling up from beneath the water in Rwanda.

In 1986, a similar phenomenon killed an estimated 1,700 people when gas erupted from Lake Nyos in Cameroon, suffocating almost everyone within 25 kilometers of the lake.

Scientists believe a similar process occurs at Lake Kivu roughly every 1000 years, devastating life in the area. If it were to occur today, some two million people living around the lake could be killed.

In order to prevent this, the Rwandan government is trying to pump the methane out of Lake Kivu, and put it to good use.

The infrastructure, however, is not ready to support the new source of available energy.

“The gas in the lake has the potential to produce a total of 700 megawatts of electricity,” [engineer Alex Kabuto] said, adding that it is much more than Rwanda needs. “It is our aim to generate enough energy to be able to export electricity.”

But that is currently far from reality.

As things stand only ten percent of homes are connected to the grid. About 11 megawatts are generated by hydroelectric power, but most of Rwanda’s energy comes from diesel generators.

I wonder if anyone is considering this as a good use case for methane-diesel options, like experimental Volvo engines.
