Isn’t petrol carbon neutral in its natural state? :D

I fancy an electric Scimitar but that has some of the worst carbon footprint claims of all alternative fuels :P

A Van Diemen RF84 rolling chassis? Is that your plan for an enhanced SS1 Jim????? :wink:

“Plan” is a bit strong Roger - “dream” may be more accurate :D

ethanol is carbon negative
If you ignore any CO2 produced during the creation of ethanol, it can be considered carbon negative until it is burnt when it becomes carbon neutral as you're then producing the same level of CO2 as that absorbed by the plant from which it is made. Still better than petrol, of course.

In truth, the only truly carbon-neutral fuels are wind, solar, tidal and wave as no CO2 conversion or emission is involved whatsoever.
A wave-powered Scimitar, now there's a thought! :)
If you ignore photosynthesis any fuel that burns is carbon neutral, even petrol until its burnt. Electric vehicles are external combustion engines, but the power could be coal, oil, hydro, nuclear, geothermal or wind power. I started using carbon negative on my Facebook page to denote a bio-fuel that was an extremely low carbon footprint. Crude oil is neutral until it gets to the rig head because companies burn the petroleum gas in a flair

But we can all blame ethanol for setting fire to our cars?. :hand:

That's why race cars use methanol all alcohols are less explosive than petrol. In fact, ethanol doesn't vaporize well that's why you have to use multi-point injection so you can squit it accurately into the cylinder, compressing it to heat it, then when it's hot it will vaporize and you can burn it

But it`s the ethanol that rots the pipes and this leads to fires :?:

And how does it get to the rig head :?: how much is a Rig to build, maintain, get to the oilfield. :w it needs drilling out, and then there`s fracking, where do we stop?.
Which is what makes me laugh about wind or wave power being cheap or sustainable, most windmills will never pay back the building, maintenance or connection costs as they can`t/don`t run 24/7.
Then there is the redundancy costs. :W .

Now don`t get me wrong please, I`m not having a go at you, just pointing out a few negatives. :pc

Good One Colin.
A quick look at DVLA says the CO2 emissions are "not available" :doh:

Although I would have thought they would be off the chart. :mrgreen:

But With the age of it, and the relatively low miles it will have travelled it will probably beat a Prius hands down. :idea:

I'm not offended that's why I looked at ethanol what people see as alternatives are not really, the oil companies have a history of manipulation and downright lying, even the American Congress tired of it and broke up Standard Oil.
It happens you just have to use a fuel of higher octane to stop it pinking and have more power/mileage CNG, propane, butane are all fossil fuels you have to drill for them, so the oil companies don't mind if we use them, Ethanol and the other bio-fuels the oil companies hate, they don't make a cut when anyone uses them.
We really ort to get back to the subject of the thread. I asked if Lockheed front brakes could be upgraded with the kit to ventilated disks.
