Come on guys, lets' not get this started again.
Brown's gas generators do not and can not work.
They are all a scam, and no one that understood simple physics would even consider them.
So, if you post that you know someone who knows someone who thought that they got better mileage or hp, then know that you've been lied to.
Repeat, they do not, and can not work.
In fact, there is even a sticky on this subject, and I know that there are some "shade trees" out there that think they can get by physics, but if you're not smart enough to pass the class, then you're not smart enough to beat God.
So, let's be done with this.
