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
Yes, the Earth orbiting around the Sun is an example of circular motion. The Earth follows an elliptical path around the Sun, but its overall motion can be considered circular due to its continuous orbiting pattern.
a umbrella can be a simple machine but it depends on how it's made
Actually sitting on the earth we feel as if we are at rest. But relative to the pole star we are moving along a circular path. Also relative to the sun we are moving along an elliptical path around the sun. So actually speaking we are not at rest. In the same nothing is stationary. Everything is in motion. Rest means only a relative term.

Sun Machine was created in 1996.
The sun has no motion because it is at the center of our solar system
There are many ways that the sun will make your weather machine. The sun could power your weather machine for example.
Earth is considered to be prograde, meaning it orbits the Sun in the same direction as the Sun's rotation. Retrograde motion typically refers to the apparent backward motion of planets when observed from Earth, but this does not apply to Earth itself.
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 motion of Earth around the Sun is the cause of the seasons.
The Earth's annual motion around the sun is called a revolution.
