RE:RE:RE: This is way better than Aurelian (ARU). Consider:.." ... 2 meter by 2 meter square of 6.73 cm thick to get to that 700 kilo weight ..."
Am I missing something here? Dirt or rock of just 2 Meter x 2 Meter x 0.06 Meter (6cm) will give a weight of 700 kg?!
I thought probably 20 kg at most for the dirt. Maybe 80 kg for the rocks.
