Thank you all for these comments but I have to bring some more information here.
As many of you have seen wacky concepts appear with amazing numbers.
Furion is a team of 8 independent engineers, some of whom are internationally recognized for their work on hybridization, connectivity and electric power.
They are academic partners including 2 schools of engineers specializing in congestion, calculation of structures and embedded intelligent systems.
It is a group of professionals, more than a delusional idea of ​​a single person ;-).
For information also, the rotary motor is no longer current for several months (the deployment despite the evolutions remains delicate and its price is dissuasive). Currently the demonstrator is realized around a motor of Yamaha R6 and has a motor of 15 KW. And the weight of the machine is closer to 240 Kg than to 200 Kg.
The site of Furion will soon be recast (it dates from a year ago, the French publications in the press are more recent) and the translation will also come and it will shed light on this adventure.
Thank you for taking this message, sorry for my rusty English.
Sportively
Marc
