No, the sun cannot be considered a perpetual motion machine. Scientists and astronomers have found other stars that used to be suns but have now lost the energy required to "operate". Our sun will eventually run out of energy and will stop producing heat for our planet.
if planetary motion is to be considered perpetual , then the answer is yes. Bcoz usage of gravity determined by the temperature of sun and the planet respectively keeps them in motion . similarly designing a machine running on no additional costs, by using forces of nature can also be termed as perpetuals . rather than considering the laws , many of their designs using nature as their support can be at least encouraged to produce power .They can be put to use to provide the needs of the hour for future development. Moreover in this Universe there is no possibility to create a perpetual machine, as any machine/least known particle can never escape the force of gravity. so y not utilise it to create green energies. if that is the case , i have seen and checked thoroughly a working prototype already which can produce 50Mw at only an one time investment of 2.5 million $ for millions of years to come.why not use them instead of dangerous+costly atomic power plants. fred7sofi@yahoo.com
A motor that requires no energy input once it is running
Even though we aren't always conscious of it, the earth, moon and the sun are in constant motion.
the ansewer is not gravity. Gravity is what keeps it around the sun. you see mercury has linear motion, which just means it is going strait. if the sun had no gravity mercury would simply fly past the sun and out of the solar system. Also if mercury had no linar motion it would simply fall strait into the sun. so.. it is the balance of gravity with mercury's linear motion that keeps it in orbit around the sun.
It depend on the sun because it produces energy.

Perpetual darkness
The sun has no motion because it is at the center of our solar system
Sun Machine was created in 1996.
There are many ways that the sun will make your weather machine. The sun could power your weather machine for example.
Replica Sun Machine was created in 2007.
it was very difficult to understand the retrograde motion of other planets if earth was considered to be at the center of the solar system but it could be easily explained if earth is considered to revolve around the sun along wit other planets. So explanation of retrograde motion of other planets made them realize that earth moves around the sun.
The Earth's annual motion around the sun is called a revolution.
The motion of Earth around the Sun is the cause of the seasons.
The motion of the sun will stop because the sun will crush on the earth if the gravitational field of the sun collapses.
