Surely the future of fuel?

<< < (3/4) > >>

I've been using B100 for about 2-3 months now bought straight from the pump in rowley regis @ 72p per litre.
However, i read on one forum that you can test whether the oil is affected by using biodiesel by seeing how many times it drips from the dipstick.
The website suggested testing the oil twice a week and looking for it dripping from the dipstick 2-3 times, any less and the oil is being contaminated by the fuel?
Since doing pump mods to my 200tdi Discovery and increasing the boost I have gone back to dino-diesel fearful of what is happening to the engine as when i checked the oil which was new 5,000 miles ago there was no dripping from the dipstick whatsoever.

its a good idea but the vast tracts of land that would have to be given up to grow it would negate the benefits as the world would starve  :?
if it was grown and every one converts you would have to pray for a good harvest if it fails your stuck with no fuel
its not strictly neutral as large diesel powered machines would plant it, crop spray it and harvest it, if its wet when harvesting then it needs to be dried using more fuel

Wonder what the yield is in terms of litres per acre?  (Or gallons per hectare :) )  Apparently rape seed oil gives the most efficient yield.

Had a quick google (tm) but can't see anything.

i saw a program about orangutans in borneo. they were massively wiped out of thier habitat because the government wanted the land for massive plantations of oil producing plants. they messed it up big style and the land went to waste. because there were trees lying about everywhere, there was a massive fire that produced something crazy like 30% of the worlds carbon emissions for that year. i, personally think we need to start putting more pressure on america, a country that has 4% of the worlds population yet uses 25% of the world oil production and still moan about 50p/ltr prices. if we're gonna fight thier wars for them than they should at least do thier bit. new technology means that we are getting more and more efficient engines. we don't need alternatives (although every little helps). we need to all pull in the same direction.

No, I was wrong.

Feedstock   US Gallons/acre   Litres/hectare
Soybean   40   375
Rapeseed   110   1,000
Mustard   140   1,300
Jatropha   175   1,590
Palm oil   650   5,800
Algae   10,000   95,000

In which case, for me to run the Discovery for a year and do 25,000 miles would take an acre of palm oil, give or take...  But I could run for about 20 years on an acre of algae.

Interesting...
