Re : 
"And you cannot use the setup on a car with an O2 sensor, as it will fake it out and screw up the mixture"

 Whoa there Hoss............that takes out a LOT of cars !!
like 95 % of gasoline cars  on the road these days.

And..........they promote it like it's 'the perfect free thing' and 'works on any car' .....
so what's the real story ?
If this 'not with an 02 sensor car' .........that takes out all gaoline watercooled vanagons.
And leaves only a few non-california air-cooled Vanagons without oxygen sensors, stock.
( which is what you have in Wa on air-cooled vanagons mostly ) 

but ..........there must be a way around it, or we're not getting the entire story here, but most cars have oxygen sensors nowadays.
And thanks Darly for pointing out some realities - 
like electrode life if current draw is too high.
They always make it sound like what I call 'Free Automatic' ...........Mother Earth News is famous for this - they'll have you believeing your car will run for free off just chicken manure.........
and the real truth is that there are downsides, challenges, and issues to overcome.
Not that I doubt that it can be done, and savings realized.  it's just not 'free automatic' is all.

Fuel prices- it's higher here in Souther Oregon than much of Oregon ( end of the supply chain from Puget Sound is a factor ) .  Diesel is at $ 4.85 and the local Biofules place has Biodiesel at $ 5,77 per gallon !
