A lithium-air battery could have an energy density comparable to that of gasoline, and thus allow an electric car to go a long distance without recharging. There are promising laboratory results.
Autonomous robots are burning unwanted weeds which might lead to higher farming productivity and lower usage of pesticides. These results are not new and the feasibility has been established. A few years ago, one of my graduate students worked on detecting weeds in a field of blueberries using deep learning.
