Upsetting the applecart #1 - carbon neutral biofuel

Therein lies another problem, because in the developing world there's a lot of burning down of nice CO2-sequestering forests to clear land for biofuel agriculture. It's not a panacea; using less fuel in the first place still has to be the ultimate goal. But still, it's better than dino juice.

As I said earlier, Biodiesel isn't the 'Holy Grail', but it certainly has more positive benefits to using it instead of dino-diesel. Oh, and it's cheaper....I'd certainly rather pay 79ppl for biodiesel than 95-99.9ppl for dino-diesel! :wink:

--- Quote from: "Eeyore" ---As may be so, but the immediate output is a huge imbalance caused by a sudden release of oodles of CO2 and other gaseous contaminents.
Gets back to what I was saying, my fossil fuel is carbon neutral, we're just debating the time-frame of it all. :wink:
But good point, none the less.

The point is, the absorbed CO2 from subduction balances the volcanic output over the course of a year, and the figures for the area we're looking at here for this gaseous exchange of carbon amounts to just 2% of total gaseous exchange of CO2 during the year.
My second point is this, the CO2 has to be absorbed by subduction before release, so if there was a CO2 imbalance (a minor local one in the great scheme of the planet), then the local imbalance before eruption is a loss of CO2 for many years between eruptions.
Just thought I should...er, point this out.
Wireless:
Anyway, the real point is this, us humans are interfering with the natural balance of the Carbon Cycle, which as has been pointed out, is the time frame of gaseous exchange of CO2 in the atmosphere.
The imbalance has caused a steady increase in CO2 in the atmosphere over the last 150 years, any 'Climate Change' is just the planet reacting to the imbalance and changes in weather systems, glaciation, precipitation patterns, and average temperatures on the planet are the result.
There's nothing we can do about the next 3 degrees or so of global warming, thats going to happen anyway, even if we stopped pushing out any more CO2 today for good, but all this crap about using the 'one life, live it' slogan as a genuine reason for ignoring or ridiculing the situation is just stupid.
Millions are going to die, or migrate, looking for land and water, and fighting wars over it, possibly for the next 1,000 years, before the World gets over what we've done to it and re-dresses the imbalance.
I'm just glad I live on a hill overlooking a river valley in a developed country, at least my grand kids have got a chance of owning beach front property when the sea level rises 70 metres.
The situation isn't funny, it's sad, and it's going to get worse before it gets better, and people best wake up to realise this before it's too late.
In the meantime, I'll run (and enjoy) my 11 year old V8 on LPG and save 15% CO2 emissions, and my pocket.

Well said. =D>
Unfortunately, the world is full of folk who bury their heads in the sand and deny that the world is changing.
Comments like "I couldn't give a hoot about my carbon footprint", as written by a member earlier in this topic, don't help. And we wonder why 4x4 owners/drivers get a bad name with attitudes like that!?! :shock:
Eeyore:
Maybe so, but at a local level, the v8 is still producing no less CO2 running LPG than it was, fact is it's probably usuing more due to a lower calorific value and a lower thermal effieciency in the engine. :wink:
The LPG was still pulled out the ground and still processed so I really doubt if the CO2 savings are as real as made out.
Yes, it's a serious issue, but if you want to take it really seriously, a smaller car will burn less lpg per mile and would be even better for enviroment. And if it's an older car it's already been built. :wink:
Be carefull what you argue, there's always a smartypants about :wink:
But at least if we can get the arguements straight in here, we can make a better statement in the bigger world. Which has gotta be a bonus.
Cheers
