Dear Crispin, On the long chain to short chain bio fuel, would this change take place if say an individual from a village collected cooking oil and ran it through a jompy boiler once maybe twice with caustic soda at 1%, would this be a good supply of fuel for a community generator? Any one up for a trial? Ps look out for BBC world challenge down to business awards 26th November 2011 on world tv. David Osborne
