And, you never followed up on a post, from a long time ago, on this very topic. Nice claim you have there....... Nice snip about the working class. Do you hear your brain rattle when you fool yourself? Maybe, harvest h202 from Venus brad, will be you sock puppet.... I don't see 'Eric Gisin' sucking on your shorts like you would have wanted. You are such a looser. But, keep claiming otherwise.......

No. Like 160 grams of CO2 / km. Graham

Care to remind me what it was ? > Nice claim you have there....... Nice snip about the working class. The rural Indian population will undoubtedly be very happy for the additional emplyment jatropha cultivation will provide. India's hardly short of the necessary workforce. > Do you hear your brain rattle when you fool yourself?

I notice you can't refute the fact that jatropha grows wild with no attention and even does so quite happily on marginal land. Graham

Shipping the stuff half way round the world to use it in the UK makes no sense at all. The only good thing that can be said for cultivating jatropha as a bio fuel in the tropics is that it probably does provide a reasonable net return on the minimal energy input needed to grow it. That is not so clear for bio ethanol production from grain at temperate latitudes. And anyway turning useful quality food into a poor fuel is insane on multiple levels unless you are a grain farmer. Some calculations suggest that the net energy returns from bio-ethanol production may be less than zero when you include all the energy costs of industrial scale planting, fertiliser, irrigation, harvesting, fermentation and distillation. > > But even more important is the paltry impact on world demand for liquid > fuels that these crop fuels will have.

Of course. I don't envy the poor sods that will have to work the crop. But I guess compared to something really chemically nasty like harvesting cashewnuts it will be a walk in the park. I hope it doesn't prove to be the invasive pernicious weed in some places that my instinct says it might be. I have grown some of them in a UK greenhouse - a few species are quite ornamental and will flower when still small... Regards, Martin Brown

His number seems quite reasonable to me. I can't see the USA giving up on ugly monster gas guzzling cars until either Washington takes a direct hit from a category 5 hurricane or oil becomes seriously scarce and expensive. Both of these are long way into the future (unless Saudia Arabia falls prey to Al Qaida). Even modest growth in car use in India and China would take the numbers up at least that far. > > The EU is already in the process of introducing astonishing standards for fuel > comsumption. My saloon car in the UK has its maximum fuel efficiency at a speed just above the national speed limit. It has a lifetime fuel consumption over 4 years of 56mpg (diesel). The new model is a less appealing shape, but with a 6 speed gearbox and aerodynamic tweaks is a few percent better still on paper. US cars still struggle to do 20mpg, and half decent acceleration is rare in vehicles with less than 4L engines. The EU attempts to encourage and sponsor wind farms is a joke though. I pass 3 big ones most days on the A19 and 2 of them are typically out of service (sometimes all 3). I can't remember when I last saw all of them turning. They are being built to qualify for grants and not to generate electricity! There are some better maintained ones up at the Nissan plant in Sunderland. 5 out of 6 of those are usually running. But the one that failed spectacularly in flames a couple of years ago closed the road. One of the major UK offshore windfarms isn't connected to the grid at all becuase the dozy b*stards did not bury the cable. Regards, Martin Brown |
