Space rover vehicles

Space rover vehicles[edit]

Manned and unmanned vehicles have been used to explore the Moon and other planets in the Solar System. On the last three missions of the Apollo program in 1971 and 1972, astronauts drove silver-oxide battery-powered Lunar Roving Vehicles distances up to 35.7 kilometers (22.2 mi) on the lunar surface.[62] Unmanned, solar-powered rovers have explored the Moon and Mars.[63][64]

Airborne EVs[edit]

Main article: Electric aircraft

Since the beginnings of aviation, electric power for aircraft has received a great deal of experimentation. Currently, flying electric aircraft include manned and unmanned aerial vehicles.

Seaborne EVs[edit]

Oceanvolt SD8.6 electric saildrive motor

Electric boats were popular around the turn of the 20th century. Interest in quiet and potentially renewable marine transportation has steadily increased since the late 20th century, as solar cells have given motorboats the infinite range of sailboats. Electric motors can and have also been used in sailboats instead of traditional diesel engines.[65] Electric ferries operate routinely.[66] Submarines use batteries (charged by diesel or gasoline engines at the surface), nuclear power, fuel cells[67] or Stirling engines to run electric motor-driven propellers.
