That the oleoresin called copaiba could be obtained by incising the trunk was first reported in England in 1625, in a work published by Purchas, "...a single tree is said to yield about 40 litres." (Grieve, 1931, reprinted 1974). Quoting nobel-laureate Calvin, Maugh says (1979), "Natives ... drill a 5 centimeter hole into the 1-meter thick trunk and put a bung into it. Every 6 months or so, they remove the bung and collect 15 to 20 liters of the hydrocarbon. Since there are few Rabbit diesels in the jungle, the natives use the hydrocarbon as an emollient and for other nonenergy-related purposes. But tests have shown, he says, that the liquid can be placed directly in the fuel tank of a diesel-powered car." (Maugh, 1976). The copal is used in lacquers, massage preparations, medicines, and paints. Wood and resin can be used for fuel. The wood is used in carpentry (Burkart, 1943).

Although not specifically recommended as a firewood, the balsamiferouswood, with density of 700-900 kg/m3, should burn readily, perhaps even when green. Calvin (1980) reports yields of 40 liters of hydrocarbon per tree per year, which can be "used directly by a diesel-powered car." Calvin sent a sample to Mobil Corporation to obtain a cracking pattern. "It produces the same kind of mixture in general as the oil from the E. lathyris [mostly aromatics (50%), LPG (25%), and low-molecular-weight fuel gas (3 to 4%) and coke]." (Calvin, 1980). In his seminar at Beltsville, Calvin (1982) seems to favor the terpenes of Copaifera to those of Euphorbia and hopes, by somatic hybridization to develop a Euphorbia, suitable for our climates, which will produce the sesquiterpenes. Apparently N-fixation has not been reported for this species.

When you are you going to show me your oiling upgrades fattywagonman?

I'll take some pics soon...

Hi Doug,
I know you think a Koel engine may have a lot better quality but don't count on it.... I'll bet a lot f the parts in your gus could be found in a Koel...some friends work at a local machine shop dedicated to natural gas compressors / engines... a lot of the Cummins NG stuff comes from india... now you would thing Cummins would be Cummins quality no matter where it's made... well they told  me horror stories about the indian cummins engines... poor fit, rough castings, dirt... yes dirt... in a cummins... Petteroid and listeroids may be the bottom of the barrel... since more folks can make them... but I have to think the real problems.... or should I say challenges come from the indian culture of "that's good enough for what it will be doing"...
Maybe Koel would be interested if you were ordering 50 engines... but for a one engine sale I think these folks have bigger fish to fry..

Yea, but 2 pole 3600 rpm for anything less than 19 kw.

Sorry but I don't understand what you meant by this?

Hi Daniel,
First Welcome....
And I'm really impressed with your press and blending and website... great information...
I'd have to say I agree with Dana that calling your VO / RUG (regular unleaded gas) blend biodiesel is a bit misleading... but lots of folks call veggieoil fuel biodiesel.... Sometimes it's a little frustrating for us greaseburners... Dana and I and about 1,000 others regularly post on the infopop biodiesel forum...
http://biodiesel.infopop.cc
You should visit... there's a lot of folks who would love to hear from you... and also a bunch of other blenders like yourself to collaborate with... 
Anyhow, good luck, welcome and thanks for sharing your information...
John

It has been discussed here how an induction motor would suffice in this regard as it would stop producing power as soon as the feed from the utility went away.  This doesn't do you any good as a backup system though.

BTW an induction motor can be modified to work as a generator... If you want a simple  / reliable / cheap net metering system... overspeeding an induction motor can't be beat... it also stops making power when the grid is down... but a circuit of capacitors could be switched in for off grid generation... 

I believe this might be the simplest way to have both net metering and standby power...

I see we lost another good resource of information...  Lister Mike left a while back... got pissed off by Mobile bob... and now apparently Doug is gone???
Pissed off by one el retardo mentalbum...
Gee with a name like that how can you take the guy serious??? actually he seems well informed... and entertaining...
But Doug had like 4,000 posts... not really but it was up there... and he was always helpful... and super knowledgeable about how sparks are made...
Some guys take this forum stuff pretty seriously... I know I've gotten it too deep on the infopop forum from time to time...
Maybe a little break might be a good thing?
Anyhow Doug, thanks for all your advise...
and if you are really gone be sure to drop me a line when gus is up and running... 
Good Luck,
John
