I haven’t found a related thread for this, “Future technologies and trends” is a broad thread and this area perhaps deserves its own thread.
For over a year, I have been following the development of electric aircraft, especially the eVTOL sector, and particularly EHang and, of course, its competitors.
I personally invested in EHang at a price of 8 and, in retrospect, too little. EHang is now at a price of 40, and the rise has occurred within 2 months.
A similar IPO/SPAC rush can be expected in this area as, for example, in the Lidar area.
There are several players in the field, including EHang, Lilium, Airbus, Kitty Hawk, and Volocopter, as well as several others.
Basic terminology can be found, for example, in EHang’s White Paper EHang UAM Systems White Paper
Among eVTOL devices, the drone-type device, like EHang, is technically probably the easiest to implement.
The more wing area gained during flight, the quieter and more energy-efficient the aircraft is for longer distances. Many eVTOL manufacturers are trying to develop a tilt-wing eVTOL device.
EHang approached the matter differently. They are developing a relatively simple drone-type flying device but are aiming to make it sufficiently safe to transport people quickly.
EHang 184 was released already in 2016, and EHang 216 in 2017. Both were already transporting people at that time.
EHang built its devices to operate without a pilot (AAV, Autonomous Aerial Vehicles).
In addition, EHang built a system for managing multiple AAVs.
So, EHang built a relatively simple flying device but constructed the entire package in a way that enables several business use cases.
EHang calls the EHang 216 structure a platform that can be modified for different use cases, such as logistics, firefighting, etc.
My vision:
As Finnair has stated, larger aircraft are not profitable for short distances (200-300km).
These could perhaps be replaced in the future by smaller electric aircraft. The load factor is easier to increase (several small aircraft vs. one large one).
eVTOL devices do not require large airports, so intermediate stops can be made on a journey from Helsinki to Tampere.
Several aircraft carrying approximately 6-10 passengers on the same route would enable dynamic route formation, depending on where passengers depart from and what their final destination is.
For example, on Helsinki - Tampere flights, some might go via Espoo and some via Vantaa, optimizing the route.
It’s easy to create mobile applications for booking.
It would be great to hear opinions on this rapidly growing area that enables F.I.R.E. for all of us 
Treidauspaikkoja siis luvassa ja jokuhan noista firmoista voi selvitä voittajana. Nyt täytyisi vaan löytää se.
