Abstract: A polyalphaolefin composition is provided comprising trimers of C12 alpha-olefins and dimers of C14 alpha-olefins, where the ratio by weight of C12 trimer to C14 dimer is within a range of 4:1 by weight to 1:4 by weight, where the C12 trimer enriched polyalphaolefin has an average branching ratio <0.2 and the C14 dimer has an average branching ratio of >0.20, and where the average branching ratio for all C12 trimers and C14 dimers is between 0.19 and 0.26. The composition has a boiling point distribution where less than 30% by weight of the composition has a boiling point between 420° C. and 455° C., and the resulting base oil has a kinematic viscosity of about 3.3 to 4.7 cSt at 100° C.

Abstract: A dielectric fluid and coolant for electrical apparatuses such as transformers. In one embodiment, the fluid contains more than 25% biobased base oil, such as a biobased hydrocarbon oil, which has a molecular weight greater than 300 g/mol and less than 595 g/mol. The biobased base oil may optionally be blended with other oils, such as mineral oils and vegetable oils.

Abstract: The application provides a base stock or a lubricant composition comprising the substances derived from algae by chemical modification of algal oil, including compositions comprising estomers. Methods for obtaining the same are also provided, including chemically modifying the algal oil with a saturated fatty acid under conditions favorable to the formation of a poly-estomer.

Abstract: Concentrating solar collector systems that utilize a concentrating reflector to direct incident solar radiation to a solar receiver are described. In one aspect, the reflective surface is arranged to direct light to the receiver in a non-imaging manner in which the solar rays reflected from the opposing edges of the reflective surface are generally directed towards a central portion of the solar receiver. Rays reflected from selected central portions of the reflective surface are directed closer to the edges of the receiver than the solar rays reflected from the edges of the reflective surface. The described reflectors are generally intended for use in solar collector systems that track movements of the sun along at least one axis.

Abstract: In one embodiment, a concentrating solar energy collector, which tracks movements of the sun along one axis has a reflective trough, at least one solar receiver mounted above the reflective trough and configured so that incident sunlight striking the reflective trough is directed toward the at least one solar receiver, and a reflector extender coupled to a first end of the reflective trough and configured to capture and direct incident sunlight towards the at least one solar receiver. In another embodiment, one or more extended end reflectors is attached with a reflective trough of a solar energy collector.
