I've read all three of your comments.
You do realize that cars don't turn the alternator off right? You'd have to actually wire that up yourself. The alternator / battery is what also runs every electrical thing in the car (you realize there's a computer, and oh my, an ignition system that requires lots of juice).
Wind drag and weight are what predominately reduce mileage, you've made both of these worse with your modifications.
2-2.5% is not a significant enough change to make any claim, the wear on your tires will actually cause WAY more error than that as time goes on (more worn tires register more distance than reality).
It's much more likely that your numbers are just wrong, and that any change in your driving habits when you decided to start being "green" make up for any true change in mileage. Pull all that crap off your car and you'll probably do even better.

I don't think you understand what a "theory" is. It's not proven, just like the "theist theory" you claim doesn't hold. You can't prove that God doesn't exist, just like you (or Dr. Hawking) can't prove that a Big Bang occured (or didn't occur). I might theorize that God created the earth to look like it's 100,000 (or pick a number) years old. You can't disprove my theory, just like I can't prove it.
Theories are like butts, everyone has them and they all stink.
...Now sure, some theories can be proven through testing and scientific rigor, but the origins of the universe (or species) sure as hell ain't one of them.

First, pick a realistic frequency range, decide what other stuff you care about.
Don't forget about probes, nice ones can be expensize, don't spend your budget then find out you need $500 in probes. Again, this depends on your frequency range.
Then, a good place to start is ebay, remember, old and working is the same as new and working +5lbs per decade of age. (old test equipment is heavy!)

Some of the new Agilent scopes are sweet, we've rented some at my office (esp if you pony up for the 15" LCD) personally, having one that requires a computer is a PITA.
Decent Agilents

Good luck.

It's not there. As mentioned in all of the comments above, the "hacker" was disappointed by not finding anything. You can find all the email online, there's nothing illegal there.
The assertion that there is something illegal has been created in a sort of slashdot liberal love-fest, that ignores facts.
