I just happened to see this topic....
There is quite a bit of theory that global warming (and cooling) is actually linked to the sun's output, which varies cyclically over time, but not in a simple way, as there seems to be many cycles which interact. The shortest cycle is the one many are familiar with, the 11 year one where the sun's magnetic field swops over, but there are also (apparently) 50 ish, 200 ish, and 1000 ish year cycles too, and probably more. The Earth got quite cold in the dark ages ( I wonder if that's not just a name?) and later in the 1700s (ish?) but was warmer than today in Roman times (apparently the Romans grew grapes in York UK, which is far too cold today, and over huge time periods Earth has been all over the place climatewise.
Anyway, that seems to make more sense to me that the CO2 stupidity, especially when other gases like SO2 have FAR more impact (so I'm told) ans mankind has pumped quite a lot of sulphurous stuff out as well....
Fuel savers - seen a few over the years, many in the carb days were simply an air leak, which weakened the mixture a bit, so quite a few actually worked, at the risk of overheating the valves of course. There's also the still going "run your leaded car lead free" out here in NZ (and UK) with these things you put in the fuel tank...Their testemonials are good too, but I still don't beleive it.
