Cars are ready to tour

Hmmmmm, I don't see an exhaust pipe/stack........Is this more like a jet, using Ayeman Ohltfahrdt's principle to convert the energy of Bio-Gas technology into a form of maneuvering "thruster" ??
In any case, that white car, won't be white for long !

I never asked the designers "how" it works either But it does move!! It's noisy too

It's running with an old trolley drive underneath and the gears are just a bit loud
