New Law Classifies Delivery Robots as “Pedestrians”

Car and Driver reports that the Keystone State technically defines delivery robots as “pedestrians” under a newly implemented measure. The law, which went into effect earlier this year, stipulates that autonomous delivery robots can maneuver on sidewalks, pathways, and roadways in Pennsylvania. They can carry up to 550 pounds of cargo at speeds of up to 25 miles per hour on roadways but must cap their speed at 12 miles per hour in human — presumably — pedestrian areas.

CO2 could become the new jet fuel

A team at Oxford University in the United Kingdom has come up with an experimental process that might be able to turn carbon dioxide—a greenhouse gas emitted by all gas-burning engines—into jet fuel. If successful, the process, which uses an iron-based chemical reaction, could result in “net zero” emissions from airplanes.
