Some countries have already committed to using electric aircraft on domestic routes. These aircraft could slash costs and emissions on some of Australia's busiest flight routes.
The battery technology and cooling systems needed for electric aircraft to lift people and cargo are getting closer to reality, but they're still very different from electric cars and trucks.
MIT researchers have built ion thrusters with no moving parts pave the way for silent drones.
Ionic winds – charged particles flowing through the air – can move airplanes using only electricity; no propellers or jet engines needed. The scholar who led the project explains how it works.
The airline industry's promised technological solutions have not arrived, and they never will.
With emissions targets to hit and oil running out, it's time to take electric planes seriously.
