VW XL1 Diesel Claims 261mpg

A group of security experts recently mentioned to me that the Oil-producing countries are all well-aware that their resources are limited. They explained this in terms of Iran’s urge to develop nuclear power.

Whether or not you accept that argument, it makes a fitting backdrop to VW’s decision to announce a super-efficient fuel-economy concept car at the Qatar Auto Show.

Take half a regular TDI engine, reduce the body weight about half, and sprinkle in some high tech bits and you get the XL1:

Now, Piech’s Volkswagen has combined state-of-the-art technology, from common rail diesel-supplemented plug-in hybrid power to carbon-fiber-reinforced polymer lightweight body material, to create the XL1. The concept consumes 0.9 liters of diesel fuel per 100 kilometers, the automaker says, which translates to an EPA fuel mileage figure of 261.3 mpg. That mileage equals 24 grams of CO2 per kilometer, VW says. Our CO2 converter converts 261.3 mpg to 0.30 pounds per mile. VW chose to unveil this car as part of an auto show in Qatar, the one part of the world where fuel efficiency isn’t much of an issue.

CIA Launches New Spy Satellites

The successful launch of a Delta IV Heavy configuration from America’s West Coast means the National Reconnaissance Office (NRO) payload L-49 is on its way into orbit.

Delta 352’s payload is officially classified; however it is widely believed to be a KH-11 “Improved Crystal” electro-optical reconnaissance satellite. The KH-11 first flew in the late 1970s, replacing earlier film-return imaging satellites like the KH-9 Hexagon. Instead of returning images by film, KH-11 satellites transmit them electronically. Four separate generations of KH-11 satellites have been identified, with the later two unofficially referred to as KH-11B or KH-12.

KH-11 satellites are designed to produce high-resolution images, which are then relayed to the ground via Satellite Data System (SDS) spacecraft in molniya and geosynchronous orbits. They are reported to resemble the Hubble Space Telescope.

The launch of NRO L-49 came amid a period of increased activity in terms of NRO launches. One Medium and one Heavy payload were launched during the last four months of last year, and in the next year two heavy, two medium and one light payload are scheduled to fly. Two NRO CubeSats, QbX-1 and QbX-2, were also launched in December aboard a Falcon 9.

I noticed an amusing comparison on pickuptrucks.com of the Dodge Ram 3500 Heavy Duty Diesel to the NASA rocket.

Delta IV Heavy:
Max payload 28,650 lbs
51,000,000hp
0.00087mpg
$600,000 to fill up
0-60mph in 15 seconds

Dodge Ram 3500 HD:
Max payload 25,400 lbs
350hp
11.8mpg
$118.65 to fill up
0-60mph in 10.4 seconds

The rocket mpg calculation seems off, since it’s calculating only the first stage and not the total distance traveled after liftoff. More to the point, it is hard to believe that a 2011 Dodge pickup still only gets 11.8mpg.

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.
