Advances in electric motors, battery technology and autonomous software have triggered an explosion in electric air taxis.
Larry Page, CEO of Google parent company Alphabet, has invested millions in the aviation start-ups Zee Aero and Kitty Hawk, both of which are striving to develop all-electric aircrafts.
It is assumed that Kitty Hawk has developed a flying car and has already submitted more than a dozen different aircraft approvals to the Federal Aviation Administration (FAA).
Page, who co-founded Google with Sergey Brin in 1998, has personally invested $ 100 million (£ 70 million) in the two companies that have not publicly acknowledged or demonstrated their technology.
The secret start-up Joby Aviation has come a step closer to realizing its flying taxi.
The California-based company, which builds a fully electric flying taxi capable of vertical take-off, has received $ 100 million (£ 70 million) in funding from a group of investors led by Toyota and Intel.
The money will be used to develop the company's megadron, which can reach 321 km / h with lithium-nickel-cobalt-manganese oxide batteries.
The Joby S2 prototype has 16 electric propellers, 12 of which are designed for vertical take-off and landing (VTOL), so no runway is required.
AirSpaceX introduced its latest prototype Mobi-One at the 2018 North American International Auto Show. Like its closest competitors, the electric plane is designed to carry two to four passengers and can take off and land vertically
The plane takes off vertically like a helicopter, before it folds away 12 of its propellers so that it can glide in the air like an airplane.
Airbus is also working on a similar idea: The latest prototype of the Vahana project with the Alpha One brand has successfully completed its first test flight in February 2018.
The self-propelled helicopter reached a height of five meters before successfully returning to the ground. Overall, the test flight lasted 53 seconds.
Airbus previously shared a well-produced concept video that outlined its vision for the Vahana project.
The footage shows an elegant self-flying plane in which a passenger sits under a canopy that retracts like a motorcycle helmet visor.

Like Joby Aviation, Project Vahana is designed to be all-electric, starting and landing vertically.
AirSpaceX is another company that has set itself the goal of bringing commuters to the skies.
The Detroit-based start-up has promised to deploy 2,500 aircraft in the 50 largest US cities by 2026.
AirSpaceX introduced its latest prototype, Mobi-One, at the 2018 North American International Auto Show.
Like its closest competitors, the electric plane is designed to carry two to four passengers and can take off and land vertically.
AirSpaceX even has a broadband connection for high-speed Internet access so you can call up your Facebook newsfeed to work during the flight.
Apart from passenger and freight services, AirSpaceX also allows the aircraft to be used to evacuate casualties and casualties, as well as tactical reconnaissance, surveillance and reconnaissance (ISR).
Even Uber is working to blow up his air service.
Baptized via Elevate, Uber CEO Dara Khosrowshahi tentatively debated the company's plans during a technology conference in January 2018.
"I think that will happen in the next 10 years," he said.
