An electric vehicle (EV), also referred to as an electric drive vehicle, uses one or more electric motors or traction motors for propulsion. Three main types of electric vehicles exist, those that are directly powered from an external power station, those that are powered by stored electricity originally from an external power source, and those that are powered by an on-board electrical generator, such as an internal combustion engine (a hybrid electric vehicle) or a hydrogen fuel cell. Electric vehicles include electric cars, electric trains, electric lorries, electric aeroplanes, electric boats, electric motorcycles and scooters and electric spacecraft.

Electric vehicles first came into existence in the mid-19th century, when electricity was among the preferred methods for motor vehicle propulsion, providing a level of comfort and ease of operation that could not be achieved by the gasoline cars of the time. The internal combustion engine (ICE) is the dominant propulsion method for motor vehicles but electric power has remained commonplace in other vehicle types, such as trains and smaller vehicles of all types.

Robert Llewellyn (born 10 March 1956, in Northampton, Northamptonshire, England) is an English actor, presenter and writer. He is best known as the mechanoid Kryten in the hit sitcom Red Dwarf, and for his role as presenter of Scrapheap Challenge.

Llewellyn's first foray into the world of show business started out as a hobby, organising a few amateur cabaret evenings in a riverside warehouse overlooking Tower Bridge in London. The shows were a great success and he eventually helped form an alternative comedy theatre group called the Joeys. Within six months he had stopped working as a shoemaker and started performing professionally with the group alongside Bernie Evans, Nigel Ordish and Graham Allum. The group toured the UK and Europe in the early 1980s with an initial idea of exploring sexual politics between men. Llewellyn wrote much of the material, and also began writing novels. The group split in 1985, having toured for years and done thousands of shows.

Llewellyn's involvement with Red Dwarf came about as a result of his appearance at the Edinburgh Festival Fringe, performing in his comedy, Mammon, Robot Born Of Woman. The story is about a robot who, as he becomes more human, begins to behave increasingly badly. This was seen by Paul Jackson, producer of Red Dwarf, and he was invited to audition for the role of Kryten.
