So where's your evidence?

See below.

The only thing that is shown below is your inability to calculate
volumes.

In the real world bioethanol cannot be 'easily produced'. It requires
a lot of energy, loads of CO2 emissions and fertilisers etc. Biofuels
from waste are still a distant prediction which may or may not become
viable. Until then they are produced mostly from food crops.

In what way is using the "scrap" from sugar beet that would normally be
thrown away using food crops, surely it making best use of the crop?

"For Each tonne of Sugarbeet: 0.108m3 of bioethanol is produced."

Correct me if I am wrong but I make that a mere 1.08 litres of fuel.

I've no doubt someone will.

So why am I still waiting?

Perhaps because you have blinkers on?

And indeed many others debunking your fuckwitted claims.

Strange, I don't see anything there which provides an alternative
calculation or source. Actually its not surprising at all, just par
for the course as usual. Either put up or shut up.

<sigh>

You really do enjoy digging yourself into a hole, don't you Dougtard?

Have a look at this:http://ts.nist.gov/WeightsAndMeasures/Publications/appxc.cfm#4e

It is a table of conversions provided by the US National Institute of
Standards and Technology. Find section 4, headed "TABLES OF UNITS OF
MEASUREMENT". Look at the eighth table. It helpfully states that 1
cubic metre equals 1000 litres.

With me so far?

Now, let's look at the actual numbers posted. The link referred to
says "For Each tonne of Sugarbeet: 0.108m3 of bioethanol is produced."

Do you know how to multiply by 1000? You move the decimal point three
places to the right (do I need to post a link to prove this, or can we
assume some basic maths?)

So, moving the decimal point three places to the right gives ... 108
litres. Wowee. So you were two orders of magnitude out. Just as
everyone said.

Now put that spade down - the good people of Sydney do not want you
emerging in their back yard.

At last, someone has managed to come up with the goods. it took you
all long enough.

<s***>

No, Duhg, we just underestimated what a retard you are. I guess
nobody thought we'd actually have to prove that 1 cubic metre is 1000
litres.

So lets get this straight then shall we, you lot all approve of
present aggrofuels, despite the considerable problems they present. So
no more trying to balance on the fence if you please.

No, I don't approve of the current policy. However, I do approve of
using waste products, such as sugarbeet residues, to make fuel.
Particularly when you can get 108 litres from a tonne.

Yes but the sugarbeet source and calc I gave wasn't based on waste was
it. No doubt if sugarbeet waste was used the yield would be much
lower. BTW, what part of the sugarbeet is waste?

Um, Schmoug, in the case you chose to refer to, all of it is waste,
because it is grown on land that is currently set-aside. In other
words, land that is not currently used to grow food. Please explain
why you think that using currently unused land could affect food
prices.

IIRC Steve F mentioned that a lot of the land being used for biofuel
crops isn't fit to grown crops suitable for humans to use as food.
