Yes, but unless the factory is right on top of the sand pit, someone
still has to excavate the sand and deliver it.  Even if this was done by
people with buckets they would need to eat to refuel, the food they
consume would somehow have used power to be grown and harvested (water
irrigation, etc).  And the unknown is always environmental impact, who
knows what impact a great big sandpit will have.

You can keep going forever, hence the ease of making any form of energy
seem better than others.
