(There is NO pointof the Earth's surface that has continuous sunlight.) In addition, note that the sun's angle changes. If the moon's equator IS aimed at the sun, then only half of the sun is visible from the poles, and you would need a tall tower (built againstgravity, don't forget) and a rotator to take advantage of the continuous power available.
