Can someone explain how or direct me to informtion regarding the power signatures of AC motors (pumps) responds as load (head) increases? I have a pump in my aquarium that is rated at 120watts, but installed with the plumbing it only draws about 55 watts (measured with a kill-a-watt device). This surprised me, but apparently it shouldnt. Any details would be great, but i'd really love the technical side/equations. Thanks!!

Why do you have to have a battery connected to a grid-tie wind power system? Can you connect your wind power devices to an inverter then to the grid? (PMG capabilities would not be greater than the inverter's normal wattage limits)
