Claim 0:
1. A solar powered watering system, comprising:
an open air water tank at least partially defining a chamber that receives water therein, and having an at least partially open top portion that provides exterior access to the water in the chamber of the water tank;
a heat exchanger at least partially received within the chamber, and comprising a closed loop tubing component having a thermal transfer fluid circulated therethrough to warm the water in the chamber of the water tank; the closed loop tubing component being at least partially submerged in the water and spaced from a bottom of the water tank;
a heat collector in fluid communication with the closed loop tubing component of the heat exchanger that transfers heat to the thermal transfer fluid as the thermal transfer fluid is continuously or dynamically circulated through the heat exchanger and the closed loop tubing component; and
one or more sensors operable to detect a temperature of the water in the chamber of the water tank,
wherein when the one or more sensors detects that the temperature of the water is below a first threshold temperature, a pump in fluid communication with the heat exchanger starts circulation of the thermal transfer fluid through the closed loop tubing component and the pump turns off when the water is at or above a second threshold temperature greater than the first threshold temperature.
