Georgia Tech team simulates risks of hacked connected vehicles; stalling 20% of cars could gridlock Manhattan

Green Car Congress

In their simulations of hacking internet-connected cars, the researchers found that randomly stalling 20% of cars during rush hour would mean total traffic freeze. Not all cars on the road would have to be connected—just enough for hackers to stall 20% of all cars on the road. Credit: Yunker lab. Yunker, Jesse L. Yunker, Jesse L.

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

Green Car Congress

Proving such a system could work with current technology was a complicated puzzle that required fitting together a lot of different pieces: high-tech cameras, vehicle datasets, artificial neural networks, and computerized traffic simulations.

The X-Ray Tech That Reveals Chip Designs

Cars That Think

In a modern processor, interconnects are built in more than 15 layers, which from above look like a map of a city’s street grid. As you ascend the interconnect layers, the features become sparser and bigger, until you reach the top, where electrical contact pads connect the chip to its package.

This Nigerian Startup’s Minigrid Began as a School Project

Cars That Think

Minigrids use distributed off-grid energy solutions that operate independently from the national transmission grid. Orajaka says his off-grid system of the first of its kind developed and implemented in Nigeria. Orajaka and the other founders have set their sights higher than just providing off-grid rural areas with electricity.

Market Update: How Battery Pack Costs Declined Since 2008

Blink Charging

Electric vehicles, renewable energy systems, and grid energy storage all rely on efficient and affordable energy storage solutions, primarily lithium-ion batteries. A battery with a capacity of one kilowatt-hour that once cost $7,500 in 1991 was only $181 in 2018, marking a remarkable 97% decrease in just three decades.
