It’s the work of some incredibly bright sparks at Airbus.
The aircraft manufacturer has unveiled the world’s first plug-in plane at the Paris Air Show.
Achieving speeds of up to 136mph, the E-Fan 2.0 prototype is, so far, able to stay airborne for one hour. The two-seater is also CO2 emission-free and nearly silent in flight.
It’s not really practical, but that’s how you get to practical. Start with a prototype, learn how things work, and what doesn’t, and improve the technology.
