basically due to whatever circumstances (width of the road, start order etc) someone has to be in front and someone has to be behind - the fact that the Stanford vehicle was following another entry had nothing to do with how it was successful, in fact one could argue it put the vehicle in some danger if the lead vehicle messed up, rolled, crashed etc. It later passed the said vehicle to go on to the win - The article makes no mention of a "Tailgating Strategy" it does say that it was tailgating another vehicle for a bit before it passed it - not sure how this is any more strategic then when I drive to work in the morning - how about this winning strategy "Don't hit the car in front of you".

Just as Europeans might not like being dependant on a US made system (and DoD run at that) We in the US may also be wary of using a European system for exactly the same reasons. Assuming that the system is ever actually deployed the winning products will be those that are hybrid systems and can utilize both systems (there actually were some hybrid GPS/GLONASS systems a few years back). I for one welcome our new European Navigation System Overlords !!
I agree, Iran is located in the most oil rich part of the Earth,One of the most oil rich countries, no reasonable person can argue that Iran needs nuke power plants to continue its industrial growth bahhhh. The only reason they want nuclear anything is to make weapons.
Bad example dude - a hybrid car gets better gas mileage primarily because:
1. Electric motors are far more efficient that gas engines.
2. The gas engine in the car can be run at a single RPM (an optimum point) since it only has to charge the betters or supply extra power to the electric drive motor - making engines that have wide bandwidths ie. 500 to 8000 RPM usually hurts overall efficiency.
3. The system can be designed to recover energy during breaking (kinetic back to potential) instead of converting it to heat.
None of these systems violates any laws of thermodynamics - I am not saying that an electric hydrogen generator would not be a great idea, I just don't think this one has any real physics or performance to back it up. If in fact there was an electric H2 generator that could supply enouhg H2 to burn all the residual fuel from an IC engine then it would be able to provide H2 at rates that could run the engine as its sole fuel source - we know this is not the case.
I agree with your analysis - the math does NOT add up - considering the amount of unburned fuel, the mass flow rates involved, and the amount of hydrogen required to burn what is left over and we have a device that itself should be able to power the car with no additional gasoline - I doubt it....
The point was that ANY additional load on the engine burns more fuel - there is no "extra" electricity just because the alternator is rotating. If there is no electrical load (current draw) on the alternator then there is no parasitic HP required from the engine (well actually a small amount due to friction in the alternator). As soon as you put ANY load on the alternator it WILL require more fuel for the engine - if you pulled off the belt from your alternator the engine would use less fuel. This is basic thermodynamics (and auto mechanics for that matter)

absolutely outstanding point - I also have bought really bad CD's because of one good song or on a bands reputation - I have also bought CD's that I had previously downloaded and really liked ! I wish the record companies would figure this out - if the band is good it will make money - if it sucks it wont.....
I RTFA, I listened to some demo's, and I can see why they are giving them away - but seriously, lots of bands allow their content to be downloaded - just because this band happens to have some members that were in bands that wrote some good tunes, does not mean that the music is good or that they are somehow breaking new ground. Go listen to the demos and then listen to this Oceans_by_Cold_Suzy this is re-capturing the culture of recording a tape to lend to your friends - not just hype...and its damn good music to boot !
OK - no arguments - this has nothing to do with... anyway until today I had never before heard it called Q-36 - so I went and did a google search and found that people call it both at about a 50% level between PU and Q. Nonetheless, I found two wave files where CLEARLY Marvin says PU, and one where it is UNCLEAR. I stick to my original statement - its PU not Q, or and BTW I'll take vi over Emacs any day:-)
the 128GB model costs about the same as a Ferrari (~$1K per GB) - as you noticed it's primary application is military and space applications - my hope is that Samsung's entry into this market will put the price point in a more reasonable area ! Even $20 to $30 per GB would be reasonable...
you can purchase one from m-systems, expect to pay about $1K per GB - a 100GB drive is in the six figure range - so far only really justifiable for military or space applications (or people with extreme amounts of disposable income)
M-Systems has been providing fast FLASH based 2.5" laptop drives in the 1 GB to 128 GB range for a while - while they are god awful expensive, they do work very well and I have used them in several mission critical applications. My hope is that Samsung can get the price point down by an order of magnitude (or two)
If you are designing a system for high reliability, under temperature extremes and such (military environments for example) underclocking is the way to go - you can minimize power and heat loads as well as potentially avoid timing instabilites that occur when you push a processor to the performance margins.

where the hell is Lexx? it makes my top 50 easily so does
Time Tunnel, Land of The Giants and The Invaders
There are a bunch of good SciFi series out there that far outranks some of the ones that made the top 50 -
I love Linda Carter as Wonder Woman, but give me a break as SciFi it does not even rate a number IMHO !
I did not say it was a good idea, but BTW thats exactly what they do in a lot of dragster race cars so that horsepower is not sapped from the engine

You made his point !

I was thinking the same thing - thanks for the chuckle my friend :-)

I agree about the drums and so does the guy who wrote and produced it - he is always tweaking - I'll make sure he gets your comments !
