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
