eVTOL company Joby and NASA collaborate to measure noise footprint of electric air taxi

Green Car Congress

As part of the two-week test campaign at Joby’s Electric Flight Base near Big Sur, California, NASA and Joby will join forces to study the acoustic signature of the all-electric Joby aircraft, which the company intends to operate as part of a commercial passenger service beginning in 2024.

ORNL researchers use stop-light cameras to reduce fuel consumption of less-efficient vehicles via traffic management

Green Car Congress

Once vehicle-classification labels were applied using commercial software, and DOE fuel-economy estimates added, the team had a unique dataset to train a convolutional neural network for vehicle identification. That was a bit of an effort, too, but that’s what it’s all about. —Thomas Karnowski.

Project shows maritime fuel cell generator can increase energy efficiency by up to 30% at part load; reliability and cost issues

Green Car Congress

Project goals were to demonstrate the use of the generator in the maritime environment, identify areas requiring additional research and development, analyze the business case, and address regulatory and other market barriers. A recent project demonstrated a 100 kW fuel cell generator with 72 kg of hydrogen storage for marine applications.

The Case for Nuclear Cargo Ships

Cars That Think

The IMO’s previous goal was a 50 percent reduction by 2050 in comparison with 2008 levels. Based on the number of players in the United States that are quite far advanced in their development, like TerraPower, my rough guess is that in 10 years we will see the first commercial civilian vessel with [next-generation] nuclear power,” says Lien.

The question becomes at what level—cell, module or pack—and when will it be validated for actual commercial use and not just sampled for proof of evidence. Therefore, the more appropriate commercial performance metric would be “ $/kWh of usable energy.”

Magnesium (AZ or AM series commercial alloy). Applications must include an existing baseline production assembly; specific targets for assembly mass; technical approach to meet targets; and a technology transfer /commercialization plan. In this AOI, solutions should be capable of being commercially manufactured.
