Two things; first, the power of light itself, and secondly, the momentum of the charged particles in the "solar wind".

Gigantic sails can be used as sun-jammers to propel spacecraft. Unlike a parasol on earth, which is used to block the sun's rays, these contraptions are designed to capture solar radiation and use the radiation energy to accelerate spacecraft.
They use their legs to push themselves off the ground or the water to propel themselves.
Flagellum
They use their tails to propel themselves backwards.
Prokaryotes use flagella to propel themselves. Flagella are long, whip-like structures that rotate like a propeller to move the prokaryotic cell through liquid environments.
Sails on a Tudor ship were essential for harnessing wind power to propel the vessel across the sea. These ships typically featured a combination of square and triangular sails, allowing for better maneuverability and speed. The rigging systems were complex, enabling sailors to adjust the sails for optimal performance in varying wind conditions. Overall, the design and use of sails were crucial to maritime exploration and trade during the Tudor period.
Spacecraft are propelled in different ways depending on their design and mission. Some spacecraft use chemical rockets for propulsion, where they expel propellant out of a nozzle to generate thrust. Other spacecraft use electric propulsion, such as ion thrusters, which accelerate ions to generate thrust. Solar sails can also propel spacecraft by harnessing pressure from sunlight.
The Greek Bireme had only one sail. It's singular sail was a very large square used to catch all the air that it can. For more information go to Wikipedia.org
They use it to stabilize themselves when they swim and they use it to propel themselves for short distances while swimming.
They both use energy to propel the vehicle. Solar cars do not exist in todays world and need serious technology increases before they will be viable.
