SOME parts of exhaust will rise.... SOME will fall. If they are (roughly) heavier than diatomic Nitrogen, they will fall, and if they are lighter, they will rise.

So, NOx (Oxides of nitrogen, where "x" is generally 2 or 3) will FALL towards the pavement. Since these are the pollutants that this pavement is trying to curb, it is a good solution.

Those lucky Damascusers.


If you didn't laugh at that, try saying it outloud! :^)

That is a very unfortunately-placed play button on that video link.

The tax that isn't being paid isn't sales tax.... it's the road tax. Our roads are paid for by a tax on fuels. If you are creating fuel on your own, you are using the roads without paying the tax. This is the same reason that the DOT of many states will occasionally dip the tanks of on-road vehicles looking for red dye.... the red dye that is added to home heating oil and off-road diesel. Again, you're avoiding paying the tax that is used to fund roads.

So regardless of how much fuel you make, even if you're not selling it, if you're using it on the roads that Caesar built, you need to pay Caesar!

Ugh. stop spreading FUD. Biodiesel from waste oil is not bollocks. (that was the word you were looking for)

It is both energy efficient AND good for the environment.

Now, if you really meant Ethanol, then we could start agreeing on something.

Wow. I didn't know there was such thing as a Ricoh Fanboi! Welcome!
