The Netherlands has developed an electric "super bus" that can carry 23 passengers and reach a top speed of 250km/h.

The vehicle is the brain child of Wubbo Ockels, the Netherlands' first astronaut and currently a professor of aerospace sustainable engineering and technology.

The aim is for the bus, which cost 13m euros to develop, to become a new form of public transport.

In May Mr Ockels will put the bus on show at a trade fair in Dubai.
