i was thinking more along the lines of space. were always getting told theres a shortage of space for housing etc where are they suddenly going to find the space to grow it all and continue to farm conventional crops and livestock ?

dont know if you seen the last series of top gear but the previous series they planted a field of rapeseed to make their own bio fuel, which ended up being bio diesel as wrong crop used. This only gave them enough to last the a 24hour race at silverstone. Granted that the car was driven harder than what it would have been on the road so more fuel would be consumed but still... it was a big field

lpg think the main problem with that was the price i was quoted £1300 to convert the car and it would take around 4 years to reclaim the cost. unless your a very high mileage driver then chances are you may be thinking about getting rid of the car by the time you recoup the cost of the conversion. even if you are a high mileage driver then chances are you would be driving a diesel, 55mpg compared to around 35mpg ( motorway driving )
