The patent filing shows Seres’ plans for an onboard toilet that slides out from the bottom of a passenger’s seat with a push or through voice-activated commands.
The loo will come with a fan and exhaust pipe to channel odours out of the car, according to the filing on China’s intellectual property administration seen by the BBC.
Waste is collected in a tank that has to be emptied manually. The toilet also features a rotating heating element that evaporates urine and dries other waste.
When not in use, the toilet is concealed beneath the seat, making full use of the space inside a car without requiring more room.


Uhm, excuse me, what is this Panzer?
Btw, i’ve once read a sci-fi dystopia story, where the few humans left all live naked in some vehicle filled with a hydro- and oilophobic smart, uh, slime? Gum? that can freely deform. You piss, the urine gets directed to a opening. You want to procreate, sperm from a matching partner gets exchanged via their vehicle. Stuff like that.
Guess they have this as their vision of the future?
So, Pixar’s Cars?
In “Mother of Storms” by Barn Jones, they had self-driving cars with a built-in toilet for long cross-country trips. I never thought it would actually be built.
