DR Congo Ring May Be Giant Impact Crater 96
Phrogman writes "The BBC is reporting that deforestation has 'revealed what could be a giant impact crater in Central Africa, scientists say. The 36-46km-wide feature, identified in DR Congo, may be one of the largest such structures discovered in the last decade.' If you search Google Maps for 'Omeonga Democratic Republic of the Congo,' you will be right in the middle of the suspected crater."

It is kind of hard to make a straight-line irrigation beam extend and contract to form a hexagon as it goes around. These plots are irrigated from underground aquifers. There's a well in the middle and then a long irrigation beam that goes in a circle around the well. The pressure is controlled so the sprinkler heads near the middle release less water (since they cover less ground).

No, you've fundametally misunderstood the problem. If you were to fit the circles inside of hexagons instead of inside of squares you'd find that 10% more area fits inside the circles.
The GP was not saying use hexagons instead of circles, he was saying hexagons instead of the squares AROUND the circles.
