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. Isobutanol produced from starch or biomass is dehydrated over an acidic catalyst to produce isobutylene, which is then further reacted to product mixtures of longer chain aliphatic hydrocarbons.

UT Austin team develops new family of high-capacity anode materials: Interdigitated Eutectic Alloys

Green Car Congress

Researchers in the Cockrell School of Engineering at The University of Texas at Austin have developed a new family of anode materials that can double the charge capacity of lithium-ion battery anodes. It is a simple, low-cost approach that can be applied to a broad range of alloy systems with various working ions such as Li, Na, or Mg.

make a low-cost “appliance”-type computer that would be as easy to use as a toaster. Mr. Jobs contributed relatively little to the technical design of the Macintosh, but he had a clear vision of the product from the beginning. One of the designers’ sidelines was to dissect the products of their competitors.
