I would like to submit this mini article to register my interest in helping to understand how coconuts could be harvested and used in vehicles and for generators as an alternative for regular fuel. From my initial limited reading you take the COPRA (the flesh/kernel but not the shell) or just collect the coconuts and pulp them down, extra purification is needed to get the coconut oil. Some people have had more success using a mixture of diesel and coconut oil, One would like to see a 100% solution for vehicles and generators as then the idea is more pure. Please comment with your knowledge on current projects in the Caribbean on this..
