Very true. Energy just doesn't come out of thin air. I've talked about the electrical supercharger with some of my collogues back in school and we basically came to the same conclusion, the amount of energy needed to provide a sufficent amount of boost would need to come from somewhere...
Gee wiz you don't say...

Yea I really didn't finish that thought did I.
...amount of energy needed to provide a sufficent amount of boost would need to come from somewhere and there isn't any place that has enough wasted energy that can easily be converted to power.
I think the best idea was to use brakes, the same way the Toyota Prius uses them in their regenerative braking system.

Why don't you have a tank that holds the air, and instead of it spinning a compressor, the air just goes into the intake. You could call it retardcharger.

Actually, the best source of energy is the fuel. We are performance guys so we really don't worry about economy quite as much as we should.
With that said, give me a gas turbine engine powering a big azzed generator. Add a few batteries for storage, but not too much. Then use one electric motor per wheel with very short axles and humongous power cables to keep down resistance.
The turbine produces all the electric power you need, burns clean as hell, can be run on alcohol and still burn clean, is light weight since it isn't fancy and is optimized to run at one specific rpm and the load is varied by fuel modulation.
This gives you these benefits:
- drivetrain mass distributed throughout the car
-low overall mass
-AWD capability
-ABS, Traction/stability controls just by varying motor speeds
-Regenerative breaking
- short axles keep the motors on the frame with unsprung mass low for better road handling.
- extremely flat torque curve from electric motors and with high current capacity allows higher performance.
This eliminates:
-Most drive axle weights since there is a motor at every wheel
- almost no transmission components gears and stuff to transfer torque.
- fluid weights
There's probably more advantages but that is what I can think of now.

I always daydreamed that the motorcycle in Akira worked like this, just with two wheels and the electric motors actually IN the wheels. And the other benefit is that you can have computer-controlled active yaw/stability control that's two steps beyond what gets done now, modulating individual wheel speed on the fly. You could even pivot around your own axis like a friggin' tank.

Has anyone heard of Rotrex superchargers. It is basically a supercharger built with a turbocharger compressor but uses a different style of gear drive to allow the compressor to spin faster. I just read abou this in the February 2006 issue of Ford Builder magazine. Some of the advantages they sated in the article: - Small size ( about the size of a softball) - Efficiency (10-15% more efficient then a roots style blower) The c30 series looks like it would be the choice for our motors. You can choose different sized compressor housings. The price for the supercharger is around $1900 but it is just the supercharger and oiling system. You have to make your own bracket and intake tubing. Here are a few links.

Ok here an idea
How about a recirculating waterfall in the engine bay that spins the "hot" side of the turbo? All you would need is a pump to catch the water and cycle it back around, Think about it, could be amazing

How about having a clear plexiglass window on the waterfall and adding little naked mermaids while you are at it.
Should keep the turbine nice and HOT....for better efficiency

I did a bunch of reasearch on them a couple months ago. In theory they sound very good. The efficiencies approach turbos. The problem is that they are using Holset compressor housings. Because they are meant for diesels, you are only in an efficient part of the map for a very short amount of time. The maps are very "thin." The result is a whole lot of hot air.
Once Rotrex starts using standard compressor housings, things should get interesting.

Now your talkin!!!!!
freaking amazing im gonna patent that [censored] right quick.
If you had a high enough pressure water it could be done, Just none of these ideas make as much sense as the obvious exhaust drivin way.
But Mermaids? Nekid? In your Engine Bay  what more could you want?
