check out this website and have a look at their "fuel saving" stuff.

their electro charger looks good but some of the others ?

modmonster -

I've been tracking the electrocharger for years and it doesn't seem to have gotten past the university-test bed. See this thread.

The other stuff probably falls into the realm of "I Want To Believe". This site did motivate me to try an el-cheapo flea-bay version of the "Hot Inazma ECO" Hyper Voltage System :

Hyper Voltage System – by Sun Automobile :: Sigma Automotive

I paid ~$25 instead of the $90 that the Hot Inazma Eco goes for.

We speck-you-mull-ate-ed that it is some kind of ultra-capacitor. See this thread. I can't say it worked one way or another, but it didn't seem to hurt either.

The "cigarette lighter" version is interesting because it documents some numbers :

Do NOT mistake this as the older "non-Super" model please! Hot Inazma Pocket Super is a new voltage stabilizer based on Hot Inazma technology. This new 2009 "Super" model uses higher-capacity capacitor than the original one. Connect it to your cigarette socket to get peak operation efficiency. A/C, stereo, lightings & many other electrical components in your vehicle are constantly creating a load on your car's electrical systems. These cause fluctuations in voltage which prevents the vehicle from performing at optimum efficiency. Hot Inazma Pocket is designed to stabilize battery voltage for enhanced electrical system efficiency. It also saves on gas, reduces emissions, brightens lights, reduces audio noise interference, purifies the cabin air by emitting negative ions (rated at 2,500~3,000 ions per cm3). New 2009 model uses dual 470 µF capacitors.

Ok, two 470 µF capacitors would mean ~950 µF. Here are some 470 µF capacitors :

Electrolytic Capacitors - 350 µF to 999.9 µF

Part Number        Capacity  Volts    Type                 Type Price   
(CFE) 000470R00DAO 470µF      16v     Axial TCX471U016E1G,  A   $ 1.25 
(CFE) 000470R00EAS 470µF      25vdc   Wendell Radial        R   $ 0.80 
(CFE) 000470R00AFA 470µF      400v    Radial Snap-In        R   $12.00

Sooooooo, 470 µF capacitors are cheap, but the pocket charger costs $130, .

Yes. I would put the capacitor closed to the coils supply to get maximum local charge.

Regarding high voltage ignition, just found out a collections of experiments under the name of "water spark plugs": http://www.google.com/url?sa=t&sourc...mmDlro55wjhZmA

Something might be worth while and similar to what shown on the site.

Note that a boost converter is quite cheap to do with today electronics.

What they are trying to do has been out forever (msd ignition comes to mind- 1978?).. but it is an informatve site with details.

I have an old school ignition.. I am remnded of crud on the battery, and no diode as a pssible reason, or prevention of back emf... I should read up on msd's version and install my own. I have played with resistors for ECU circuits with great success..but ignition is a scary thought to me.. I must get over it.

When I get to it, I will post the 3 dollar cure..maybe even from radio shack. (thier stuff is ever so tiny however)
I have ordered from the net.
