Claim:
1. A system comprising: a source of an oilseed product that comprises a storage vessel containing the oilseed product or a processor that converts an oilseed into the oilseed product; a source of supercritical carbon dioxide; a source of alcohol; an extractor in communication with the source of an oilseed product and the source of supercritical carbon dioxide, the extractor being constructed in a manner that affords suitable mixing of the oilseed product and the supercritical carbon dioxide under conditions effective to extract seed oil from the oilseed product, wherein the extractor has an exit port; a reactor in communication with the exit port of the extractor and the source of alcohol, the reactor being constructed in a manner that affords suitable mixing of the seed oil with the alcohol under conditions effective to transesterify the seed oil, thereby producing a biofuel product, the reactor having an outlet; a power source that operates on a biofuel energy source to produce heat, wherein the power source is in communication with the outlet of the reactor to utilize a first portion of the biofuel product as its biofuel energy source and wherein the power source is selected from group consisting of an engine, a generator that also converts mechanical power into electrical power, and a direct-fired heater; wherein the system further includes at least one of (i) a heat transfer mechanism that transfers heat from the power source to the extractor, the reactor, or both the extractor and the reactor, and (ii) a collection reservoir that receives a second portion of the biofuel product.
