    Hi Frosty,
    As with advanced societies with readily available electricity, - That sounds like it... In PNG the serrated spoon thing is called a "se-crub" - also the term used when one is itching for sex ? :eek:

    The flesh from a mature coconut has oil and gentle simmering that desiccated mix with the coconut water will release the oil which will rise to the top as it cools over night...

    Oh --thanks mas,-- I wont tell any body.

    Err,-- how many mature nuts to a liter of oil. Do you do anything else to it before decanting into your tank--what about a bit O diesel in with it.

    Commercial Coconut oil is $US1,170.00 per metric tonne,(http://www.apccsec.org/document/PRICES.PDF) so thats about $1.20 a litre.

    The concept collecting. splitting, scraping and boiling 100's of coconut for fuel (after collecting all the husks for cooking the stuff) seems a bit impractical to me. I bet there aren't too many people who would run the stuff through their $15,000 engines, especially a long way from land.

    It also solidifies under 22c http://www.sivglobal.org/?read=118, and at seas, that would happen a fair bit in the tropics. I don't fancy cleaning out the injectors every morning, assuming you can reach them easily

    Hey - i just found a calculator for converting nuts to oil - (13 nuts per litre) http://www.sivglobal.org/?read=118

    Once filtered to finer than 5 micron. as good as the best diesel at your local service-less fuel-stop... In the remote islands of Melanesia you will not find any of those around the next intersection, and unless you prearranged and pre-paid - not likely there will be any available in 200 l drums either... I have used it, and I would rather that than rely on drifting... (Coconut oil solidifies at about 24 degrees Celsius)...

    At US$1170 per metric tonne, That is way cheaper than diesel at Urangan Marina, Hervey Bay, where I paid Au$2.75/litre, just 3 weeks ago.... S.G. (specific gravity) is around .8? so about 1250 litres, so that is Au$1064 (US$1.10 per AU$) per 1250 Litres or Au$0.85 per litre - - less than a THIRD of the Urangan PRICE I paid :eek: :) :)

    It would be a miracle if you could find diesel filtered better than 50 microns at most pumps. My system for my truck filters it down to 1 micron and its not all that easily done. You have to heat it in order to get that kind of purity with any kind of reasonably priced filters. Basic Purilators work fine but they are designed for oil at 140°F+ - a few. Not cold diesel fuel.

    I often laugh at people with 5 micron filters on there engines.I think gas pumps are filterd to 30.

    I mean 5 microns thats ---err well,-- very small.

    Do not heat diesel to 140°C as that is close to the flash point, I am told.... I filter to 5 micron now... What are your injectors? 10?

    Dunno --I rely on Yanmars engineers for the final filter, If it good enough for them its good enough for me which is Toyota filters with water alarms in the bottom.

    different fuels = different flash points, Motor oil is about 450°F+ diesel fuel is about 150 or something like that. Motor oil in the basic engine is runs at a slightly higher temp that the coolant temp, Most coolant runs at about 140°F+-. The whole oiling system is geared to run at a specific temp, the filters don't operate ( pop valves may be open ) when the oil is to cold to run through at a given volume. Deal is if you want an oil filter to filter oil properly you have to heat the oil. If you want a fuel filter ( diesel ) to filter down to say 1 micron or even 5 your way better off pre heating the fuel to some fraction of its flash point. Its different for each type of fuel but by preheating it you not only increase atomization out of the injectors but you also run cleaner fuel through the filters.

    My system runs on motor oil so optimizing one for diesel is something I haven't done, but the lower flash point does make the fuel less stable and the risk of accidental detonation ( frosties point is well taken ) a very real possibility

    That price is for commercial quantities, as it is quoted as 'ex Malaysia'. You would only get that price if you bought a commercial quantity (half a tanker ? ) of it.

    We only pay $1.40 in civilized Australia for Diesel, so you trying to buy small quantities of Clean Coconut Oil (CCO) in primitive far off lands (PFOL) for less than Diesel with a purity of a 44 gallon drum left on a wharf for 6 months, seems really remote. The availability of CCO suitable for engine use will be even more remote than prepaid commercial fuel.

    Even if you can get CCO without water, fibre, particles etc, it solidifies at 22C - 25C, it is no better than 'drifting' - because that what you would be doing.

    "You have used it " ? - maybe, but not in those new motors of yours ever, or anytime soon.

    http://www.kokonutpacific.com.au/CoconutBiofuelKP.php puts a bit more realism into it eg.
    " A coconut oil/diesel fuel blend currently being used in Vanuatu initially mixes 20 parts coconut oil with one part kerosene. This blend is then mixed 2:1 with diesel to give an effective 64% coconut oil bio-fuel. "

    "It runs best with indirect injection systems"

    "It is NOT successful with Lucas/CAV rotary injector pumps and the more modern engines but older style engines coming out of China and India are much more suited as is gravity feed fuel tanks."

    Vanuatu has a night temperature on windless nights too cold for neat CNO, hence the blend... In Honiara I drove a 1991 toyota landcruiser 4x4 ute that had been run solely on CNO... A ***** to start as the mornings were a bit cool there too, but NO HASSLES once running...
    Up around PNG and the northern parts of the Solomon Islands - http://www.bom.gov.au/oceanography/forecasts/idyoc13.shtml?region=13&forecast=1 - you will note that the sea surface temperature NOW, IN MID WINTER is still quite warm - mostly above 26°C ... In Summer, expect the water temperature around 32°C...

    CPL in Rabaul used to sell CNO by the tonne... and the illustration above was that of "an illustration"... The price used to be set and applied for all Coconut oil...

    Hey Mas, why don't you simply get someone to travel with you when you need to move the boat, put an ad on the marina notice board, or place an ad in fleabay, i bet there would be travellers just busting to go somewhere on a boat. I will if you pay my airfares, but surely someone will if they get a trip, many think it an adventure to "go to sea".

    Err but the reliability factor concerns me a bit... Whoever goes up will need to come back with me... and being on a pension, would need paying crew... :eek:

    Nil insurance, - once 200 mile off-shore most declare "all bets are off"...

    I got coverage whilst in marinas for the mandatory 10million in 'third party' and 'public liability', beyond that they are talking 10% and more PA... WTF ???

    I still need to save up for the 3 blade fixed 15" x 11.5" pitch propellers, and would really appreciate being able to satisfy myself to make CNO ship-shape for remote operations - - as far as mast, sails, Christie Engineering battery charger & water-maker...

    Hey Mass, old friend, explain if you would the insurance thing, I'm way out of the loop but hoping to begin soon as Iget the truck out of the shop. So whats the deal with insurance at the marina.

    Mas, if you are interested in cheaper than 10% let me know, cos I can get it for 1%...I am a shippy remember.
