“A concept for AV expressways promises to reduce travel times, but falls into an old trap of car-centric planning.”

“In May, GM spent $1 billion to buy Cruise Automation, a small startup with promising self-driving software.”
The July 29, 2017, tests hit record test speeds traveling nearly the full distance of the 500-meter DevLoop track in the Nevada desert.
‘This is the beginning, and the dawn of a new era of transportation,’ said Shervin Pishevar, Executive Chairman and Co-founder of Hyperloop One.
‘We’ve reached historic speeds of 310 km an hour, and we’re excited to finally show the world the XP-1 going into the Hyperloop One tube.

Paint these days is becoming much more than it used to be. Already researchers have developed photovoltaic paint, which can be used to make “paint-on solar cells” that capture the sun’s energy and turn it into electricity. Now in a new study, researchers have created thermoelectric paint, which captures the waste heat from hot painted surfaces and converts it into electrical energy.
“I expect that the thermoelectric painting technique can be applied to waste heat recovery from large-scale heat source surfaces, such as buildings, cars, and ship vessels,” Jae Sung Son, a coauthor of the study and researcher at the Ulsan National Institute of Science and Technology (UNIST), told Phys.org.
“For example, the temperature of a building’s roof and walls increases to more than 50 °C in the summer,” he said. “If we apply thermoelectric paint on the walls, we can convert huge amounts of waste heat into electrical energy.”
