Researchers demonstrate effective silicon-based thermoelectric generators

Green Car Congress

A University of Texas at Dallas physicist has teamed with Texas Instruments Inc. to demonstrate thermoelectric generators (TEGs) created using nanostructured silicon thermopiles fabricated on an industrial silicon complementary metal–oxide–semiconductor (CMOS) process line. The marginal cost is a factor of 100 lower.

Profiteering Hampers U.S. Grid Expansion

Cars That Think

At the heart of the problem are utility companies that refuse to pursue interregional transmission projects, and sometimes even impede them, because new projects threaten their profits and disrupt their industry alliances. The goal is to keep the lights on at a low cost by utilizing an efficient mix of power plants.

Gevo to supply alcohol-to-jet fuel to Virgin Australia

Green Car Congress

Gevo will supply the ATJ from its hydrocarbon plant based in Silsbee, Texas. The Queensland government is supporting the arrangement as a first step in the development of a renewable jet fuel production industry in the state. We believe Queensland offers huge potential for low-cost, biomass-based feedstocks to produce biofuels.

b) Comparison of tensile strength and strain to failure (elongation) of Ti-185 alloy with other commercially available Titanium alloys. However, wide scale adoption of β-titanium alloys in transportation applications has been limited due to its high cost. a) Ultimate tensile and yield strength of Ti-185 for three STA conditions. (b)

GWU team demonstrates one-pot process for optimized synthesis of controlled CNTs from CO2; coupling cement and C2CNT

Green Car Congress

This research article focuses on a highly favored route to the synthesis of controlled nanostructures at high rate, high yield, and low cost by molten carbonate electrolysis. A challenge to the economics of carbon capture at a cement plant is the relatively higher cost of capture compared to other industrial products.

make a low-cost “appliance”-type computer that would be as easy to use as a toaster. Briefly he considered building the plant in Texas, but since the designers were to work closely with the manufacturing team in the later stages of the Macintosh design, he decided to locate the plant at Fremont, Calif.,
