The 3.2 litre CDI out-accelerates the 3.2 litre gasoline engine, in this car. (That's why the CDI is priced higher than the gasser in the U.S.: If it goes faster, it should cost more. Nice logic!)
On another diesel performance note, check out:
Land speed record for pickup trucks (217.202 mph) is set by street-legal diesel-powered truck, which pulled its own team trailer from L.A. to the Salt Flats. And, it wasn't trailing a plume of black smoke!
we used gallons of vegetable oil to wind up with a couple litres of fuel.
Then you were doing something wrong.
Some facts: one gallon of vegetable oil will produce one gallon of biodiesel (you also add some methanol and lye, but not in large quantities).
One acre of each of these crops can produce this many gallons of biodiesel: soybean 49, sunflower 84, canola 76.
when she said it produced no carbon dioxide, I just switched the channel.
Biodiesel produces no net increase in carbon dioxide. Burning biodiesel does release carbon dioxide, but the plants grown to produce the biodiesel convert carbon dioxide to oxygen in the same or higher amounts.
All diesels can run on biodiesel. The only issue is that biodiesel is highly solvent, so it will "eat" rubber hoses and gaskets. They must be replaced with synthetics.
If you are planning to run straight or waste vegetable oil (SVO/WVO), then you need to modify the vehicle.
Biodiesel is not SVO. It has been processed with methanol and lye to convert long carbon chains to short.
The use of biodiesel in a conventional diesel engine results in substantial reduction of unburned hydrocarbons, carbon monoxide, and particulate matter compared to emissions from diesel fuel. In addition, the exhaust emissions of sulfur oxides and sulfates (major components of acid rain) from biodiesel are essentially eliminated compared to diesel.
And:
The CO2 released into the atmosphere when biodiesel is burned is recycled by growing plants, which are later processed into fuel.
ie. Biodiesel provides no net increase in carbon dioxide.
Most comparisons focus on the difference between biodiesel and dino-diesel, not gasoline. However, in general, gasoline has higher levels of greenhouse gasses and unburned hydrocarbons. Biodiesel produces more nitrogen oxides than gasoline, which, combined with unburned hydrocarbons, makes smog.
The article is making something mundane sound really impressive. A little research shows that there is an entire community of Ultra-Large Format Photographers who will laugh at this guy.
After all, ULF cameras can be easily purchased commercially, at sizes up to 20x24:
Ebony cameras (Look at bottom-left frame for 20x24 cameras).
Film (which comes in single-shot sheets) must be custom-ordered from Kodak, Fuji, Ilford, Bergger, etc.
As far as the focussing question: these cameras have movements such as tilt and swing to change the plane of focus so that nearby blades of grass and distant mountains are all in focus.
Again, nothing innovative, radical, or impressive is described in this article. If the reporter had bothered to do some research, he would have found some far more impressive photographers to highlight.
We can divert resources from subsidized production of corn-based sweeteners (that are making everyone fat) to biodiesel. Switch from drinking sweetened soft drinks to water, and there is a good supply of raw material for making biodiesel.
Then encourage development of biodiesel/electric hybrids.
Since the Ferrari laptop has a logo and red paint job, does this one have an ugly Hummer-style case? Does it make machine gun sounds when you fire it up?
4. I find it offensive to refer to the general public as "consumers". Maybe it's just me, but it reeks of a corporate world view where the only thing that is relevant is the exchange of goods and services and lets not forget where your place is in this relationship.
Whenever you hear George W. Bush speak, replace the word "citizen" with "consumer". Then, everything he says makes more sense.
In the case of U.S. corporate world view, the fish stinks from the head.
Well yeah, if you shoot N-2 all the time, you end up with some very "flat" negatives, which are very difficult to print.
One of Adams' goals was to get his negs as close as possible to printing on Grade 2 paper. I would have to assume that is because printing onto higher contrast paper add some "compromise" into the final quality.
With HDR digital capture, you can take any tonal "slice" you want, or compress and expand tonal ranges, with no penalty (assuming you have enough bit-depth in your original data). You are not limited by your output (printing) medium, in this regard.
Adams would be very excited about the potential of digital to capture more information than film is capable of.
High Dynamic Range digital sensors/cameras already exist. The only thing lacking, right now, is the high resolution, single-shot capture, and portability you get with a large-format camera, compared to scanning large-format sensors (which are only practical for studio work).
Previsualisation is born from the understanding that the medium (film) has certain limitations in what it can capture. Thus, a decision must be made in the field, at image capture time, about what information is important to capture, and what can be thrown away. Adams had a thorough understanding of the limits of his medium (from film through to printing), so he could make these decisions.
If you are able to capture more information in the field, you then increase your option to make decisions at printing time.
Adams was very interested in the technology of photography.
In his day, Dr. Land's Polaroid system was a controversial and "new-fangled" technology, which most established photographers dismissed out of hand, just as digital is controversial and oft-dismissed now.
Adams was very involved in the development of Polaroid instant materials.
Ultimately, he sent over three thousand memos to Polaroid.
One of Adams' famous Yosemite photographs,
El Capitan Winter Sunrise,
was shot on B&W Polaroid negative material.
Adams was always open to new technologies and ideas if they could provide him with more control over his medium, and increase quality.
If he rejected a new development, it was usually because it did not take him in the direction he wanted.
As far as digital goes, he would not only be interested in it, he would be actively guiding its development towards his personal and professional goals.

I don't know about double, but:
The diesel engine is 20-40% more thermally efficient than the gasoline engine, ie. it loses less energy to (wasted) heat production.
Diesel has more energy per volume than gasoline, ie. a gallon of diesel contains more energy than a gallon of gasoline.
So, you will get more miles on a gallon of diesel, all other things being equal.
All diesels can run on biodiesel. The only issue is that biodiesel is highly solvent, so it will "eat" rubber hoses and gaskets. They must be replaced with synthetics.

I'll insure my wrist for $60k, in case of carpal tunnel syndrome!

Yeah, but IBM has also contributed. They added all of SCO's intellectual property into Linux! :-)
I, for one, won't start saving until they come out with a replaceable battery...
Start saving!
You can replace an iPod battery yourself for $49, or pay Apple $105.95 to do it.

What are they doing with my feet? Give 'em back!
Microsoft does not "innovate" anything.
To be accurate: They can make a second-rate copy of Google for less money.... After a few versions, it will become usable.
The French are very patriotic. They love France.
However, they are often anti-American.

Will Rob Enderle buy one?
Free trade has three requirements:
Outsourcing of jobs to India does not satisfy the third criterion. Technically, it is incorrect to call it "free trade".
The only true free trade system I am aware of is the European Union.

So, we'll being seeing some Waco-style standoff between the RIAA and a CD-bootlegging cult on the news?
Yeah. I want to start giving out traffic tickets to all of the dumb*sses here in L.A. who can't drive.
Where can I buy a siren and flashing lights?
No one has contracted Mad Cow Disease from their shoes....yet.
It looks like FWB's RealPC is a strong candidate. The management struggle accompanying the exposure of RealPC vaporous nature is also entertaining.
