Floor sweeper

The future of battery driven vehicles for specialized purposes, such as the electric locomotives using during construction of the Channel Tunnel which used 100 kWh batteries, or the floor sweepers/scrubbers now used in airport terminals, industrial premises and railway stations, is assured. What is of much greater significance is the future of EVs in the general automobile industry which currently has a turnover of some 500 billion.
