An old man has built his beautiful house on an unused bridge for excellent scenic views of the landscape. However there is a problem, demolition crew has arrived and have set charges to the sides of the bridge that connect it to the land-masses. The demolition crew does not know of the old man and vice versa, because the bridge is very long and the old man has resided in the middle of it. Meanwhile, the old man while enjoying the natural scenic vistas is about to set all possible positions on a 3x3x3 Rubik's Cube, he has clumsy hands and can only do one position per second. He is daring to do this because he has stopped aging, and thus he can live forever, provided nothing physical happens, such as the destruction of the bridge. The bridge measures in height of 20,000 feet and in length an impressive 1.9x10^15 km. The bridge is only linked on either sides of land-masses and is not a suspension bridge. There is standard atmospheric pressure and gravity, just like on Earth. At 20,000 feet, the old man's house is pressurized. Also, he has several massive stockpiles of food that will last for almost unlimited amount of time. He spends 9 hours on sleep, 3 hours on food and exercise, and from now on will be spending 12 hours on Rubik's Cube in a single 24 hour day, everyday. Sadly, just as he makes his first position on the Rubik's Cube, the charges are detonated. How many position(s) of the Rubik's Cube was the old man able to do before he died?
