designer's own words:the pedestrian crossing bears raised danger both to the pedestrian and to the driver of the car. especially danger increases at night time. for reduce risk create eCross. it is a piezoelectric plate will transform energy mechanical to an electricity. process is very simple. Install eCross along pedestrian crossings. during pedestrian crossing moving, the car charges accumulators through piezo elements . with darkness approach, accumulators feed lamps with an electricity for pedestrian crossing illumination. the technology allows to make plates not big height 3-4 cm. but even the barrier of such height creates effect "the lying policeman" that creates even more favorable environment in order to avoid failure. eCross is a safe pedestrian crossing using only green energy.
