					A dip or hollow increases the energy potential of a 
					certain sector. | 
				
				
					| • | 
					Weights reduce the energy potential of a sector. | 
				
				
					| • | 
					A source of water in a sector of positive energy 
					increases its energy potential, while if water is placed in 
					a sector of negative energy, the potential of this sector is 
					reduced. | 
				
				
					| • | 
					The more a certain sector is covered by a roof, the more 
					its potential is reduced. |
