Aachen team develops framework for model-based formulation of biofuel blends with tailored properties

Green Car Congress

A team at RWTH Aachen University has developed a framework for the model-based formulation of biofuel blends with tailored properties by considering the fuel’s molecular composition as the fundamental design degree of freedom. Based on the selection of a palette compound (Stage 1), a conversion pathway is created in Stage 2.

New study finds GHG emissions from palm oil production significantly underestimated; palm oil biofuels could be more climate-damaging than oil sands fuels

Green Car Congress

Business-as-usual’ projections of future conversion rates, based on historical rates over the past two decades, indicate that 6–9 Mha of peatland in insular Southeast Asia may be converted to plantations by the year 2020, unless land use planning policies or markets for products change. —Miettinen et al.

EPoSil: electroactive polymers for generating electricity from wave power

Green Car Congress

A German consortium involving four companies and and two universities is developing dielectric elastomers (electroactive polymers) for the conversion of mechanical energy—in this case wave power—into electrical power. The Technical University of Darmstadt is developing a method for testing the electroactive polymers.

New Review Concludes Very Low EROI of Oil Shale Combined with High Carbon Intensity Likely Makes it an Unsuitable Alternative to Conventional Crude Oil

Green Car Congress

A comparison of estimates of the energy return on investment (EROI) at the wellhead for conventional crude oil, or for crude product prior to refining for oil shale. While one could argue that the char and gas produced and consumed within the shale conversion process has zero opportunity cost—i.e., Source: Cleveland and O’Connor.

In comparison, the state’s goal is to achieve this amount by 2050. This situation is not true universally. Palo Alto’s government has set a very aggressive Sustainability and Climate Action Plan with a goal of reducing its greenhouse gas emissions to 80 percent below the 1990 level by the year 2030.

Electrification has its sustainability challenges,” notes Daniel Ludois , a professor of electrical engineering at the University of Wisconsin in Madison. Krein does not have any financial connection to C-Motive.) For comparison, the relative permittivity of air is 1. For larger motors, however, the opposite is true. “At

New Watch Motor Seeks to Outsmart the Smartwatch

Cars That Think

The company has used silicon microelectromechanical systems (MEMS) to produce an entirely new wristwatch motor for analog watches that’s half the size and roughly three times as efficient in comparison with the standard stepper motor now used in wristwatches. To get rotational motion, levers and crankshafts are connected to the moving combs.
