K-VEC in synthesis
Quick recharge of a pack of ultracapacitors on board the vehicle, at every charging station;Automatic 5”/20” connection between the vehicle and an
energy “feeding carpet” set on the road surface, will allow a 1-10 km trip.

Quick recharge
A plate (9a), set underneath the bus, made of“spring” prods (9b, 9c), lowers at every station and pressing the “contact

and pressing the “contact carpet” “sucks” the energy from it.
Actuators (9d) are
required to allow the plate to move up and down

Solar energy PV shelter
The station may be partially/completely
self feeding, thanks to a PV roof which permanently
recharges the ultra-capacitors of the station
