Doc Brown could have been driving the Rolls-Royce Hybrid Aircraft instead of a Delorean when he said, “Road? Where we’re going, we don’t need roads.” Unveiled at the 2018 Farnborough International Airshow, the Rolls-Royce EVTOL (Electric Vertical Take-Off) vehicle was designed to be adapted as personal or public transportation, with use in logistics and military applications as well.
The hybrid aircraft uses gas turbine technology to generate the electricity needed to power the six electric propulsion units. Because of the hybrid nature of the vehicle, noise emissions are kept low. Battery storage is projected to be enough to carry four or five passengers at speeds of 250 miles per hour for an estimated 500 miles before requiring re-charging.
Back to the subject of roads, because the wings can rotate 90 degrees, the vehicle can take off vertically, meaning that you only need a landing pad, such as those already at heliports and airports. Once air born, the propellers on the wings can fold away, leaving just the two rear propellers for thrust.
By the mid 2020s, the Rolls-Royce Hybrid Aircraft will be in production and available, leaving the question of what to do with all these roads we have now.
