Well, it did start a rousing discussion about whether it was appropriate to do so. And apparently, that is worth discussing

Yup, I'd bet so too. A similar project is under development at Georgia Tech. Here they are using pieozoelectric transducers, but that may just be for the model. The real research is for supercavitating torpedoes. This is where the torpedoes form a pocket of water vapor around themselves to reduce friction. I don't know if all torpedoes use this and if the research in the article is part of the same project. This research project collapses the air bubble causing the torpedo to either detonate or its motion to become unstable. The focus here is to determine the necessary input to disrupt the vapor pocket, not the development of the phased array.
You must not have had the pleasure of attending Chem 1A from Professor Pines. He would ask multiple choice questions that were very conceptual: "If we do this, what happens? Will blank go up, down, or remain the same?" But the key thing was that he would pose the question and then have us talk amongst our fellow students. This got people involved. This was in Pimentel Hall, lots of students. He had a way of getting people to pay attention and participate. Yes, there were those who slept through class and those who didn't raise their hands until they saw what other people thought, but they were definitly not in the majority.
I agree that some lecturers just go through the book and don't provide insight, but there are some that put effort and considerable thought into their primary job as a professor, teaching.
I suggest you find the professors that do so and get your money's worth. It will get back to the professors that have low class attendance and reviews.
The real life (and unscientific) efficiency test by the article's authors did show an improvement over the rated MPG (in fact, about a 10% decrease from 10.5 rated to 9 liters per 100 km). As I recall, direct injection is already a tested meathod to increase burn efficiency, without the electrical power conversion problems you mentioned.
But, the device did reduce pollutant production drastically (albeit measured by a puportedly unscientific emmisions test).
I think the real benefit here is the reduction of pollutants, not mileage increase (or decrease if you're not in the US).
I've taken the class. Yes, yes it does. It plays any MIDI file with a guitar part to it. It also plays "Layla" and flight of the bumblebee.
What is really amazing is that it was put together in a quarter by three students.
Also, note that Pixar uses Macs and PC's running linux for animation.
What kind of computers does Pixar use to make its movies? "We use Macs, we use PCs running
Linux," Jobs admitted. "It pains me to write that purchase order to Dell."
If memory serves me, it's a mixture of aluminum and plastic powders and most likely non-toxic. That doesn't mean you don't want the kids to be inhaling the stuff, however.
It's pretty cool. Basically, it's a microprocessor with some snap on sensors and motors. You then have the option of programming it with the included visual programming language, or you can use one of a miriad of more advanced languages availible.
Back when it first came out, my Dad and I competed in a sumo cometition held at his work. It was really fun as a high scholl student to be able to play around with robotics and see how changes in code can affect the behavior of the system.
I searched for "welding control" and got back a list with no places trying to sell me welders or welding supplies. Mostly, I got back useful papers that are not availible through my school's library. This is where this idea could shine.
Good Stuff.
The system does need a overhaul, though.
Just my two cents.
While PIXAR uses macs for light use (i.e. the person working the front desk uses an iMac) the computers used for higher load applications (not to say that solitare is not high load:) ) have always been suited to the job. When SGI was king at graphics rendering, that was what they used, but Linux is cheaper and can muscle through it. I doubt they would switch over to G5's now as they just finished switching out the renderfarm for new boxes.
Is there any other reason to watch TV than to catch one of 3 different daily showings of the simpsons? This thing would be useful if you're stuck somewhere far away from your fix.:)

There are over five years of projects with pictures, video and more.
By the way, the develoment TA, Akio (not me), is looking for a job ;)

Now, I don't know for sure when the Concordia project was made, but I do know the GaTech one was made in 2000.

Nothing like trying to draw a circle on that sucker.
Yeah, I prefer the scabbed edge.
Worst website ever!
No, it uses a free piston hydraulic pump that runs off catalyzed hydrogen preoxide. Actually quite small and light for the power it provides.
...that will put him in pound-you-in-the-ass prison...
Shouldn't that be Federal-pound-you-in-the-ass prison?

Why don't they just give up! This is just wasting a lot of time. Bastards.
The wonderful folks at Princeton are keeping track of our activities. Check out the effect of slashdotting on their traffic here.

Just make 'em out of diamond and all your problems are solved. Great heat transfer coeficient so you don't have to worry about heat anyway.
Just so you know, Disney has extremley little to do with making the movie. They are the distribution and marketing, little else.

Now I'm REAlLY lame.
FP!!
