NOVELTY - The portable stationary power generation system (10) for producing high quality vegetable oils and biofuels, comprises a source of a seed oil, a source of alcohol, a reactor (40) that has an outlet (46) and affords suitable mixing of the seed oil with the alcohol under conditions effective to transesterify the seed oil, thus producing a biofuel product, a power source (50) that operates on a biofuel energy source to produce heated exhaust that is discharged via an exhaust manifold and is in communication with the outlet of the reactor to utilize a portion of the biofuel product.    USE - The portable stationary power generation system is useful for producing high quality vegetable oils and biofuels, for harnessing the biofuel product to generate heat and electricity, and for operation off a power grid.    ADVANTAGE - The power generation system ensures economical production of the vegetable oils and biofuels with high quality, high throughput and less energy consumption without the risk of fatty acid methyl/ethyl esters decomposition in continuous and less time consuming manner.    DETAILED DESCRIPTION - The portable stationary power generation system (10) for producing high quality vegetable oils and biofuels, comprises a source of a seed oil, a source of alcohol, a reactor (40) that has an outlet (46) and affords suitable mixing of the seed oil with the alcohol under conditions effective to transesterify the seed oil, thus producing a biofuel product, a power source (50) that operates on a biofuel energy source to produce heated exhaust that is discharged via an exhaust manifold and is in communication with the outlet of the reactor to utilize a portion of the biofuel product as its biofuel energy source, a heat transfer mechanism (54) that transfers heat from the exhaust manifold to the reactor, a collection reservoir that is in communication with the outlet of the reactor and receives a second portion of the biofuel product, and an electrical power storage device. The reactor is in communication with the source of the seed oil and the source of alcohol. The power source converts mechanical power into electrical power, and is a diesel engine or a thermal heater. INDEPENDENT CLAIMS are included for:    (1) a biodiesel engine system;    (2) a system;    (3) method of making a biofuel product; and    (4) a biofuel product.    DESCRIPTION OF DRAWING(S) - The diagram shows a schematic illustration of a system for the conversion of vegetable oil to biodiesel fuel.
