Peter Curran attempts a pioneering 4500 mile drive round Europe in a battery-powered electric car.
Peter travels through Denmark, Norway and Sweden, countries he finds to be very eco-friendly - though at this time of year also very rain-sodden.
He visits Samso, known as Denmark's Energy island and is invited to lead a 100 electric car convoy round Olso, one of the largest ever gatherings of electric cars.
