No need for power lines, no need to buy diesel fuel—sunlight is all it takes to get water to the fields.

Delivering water to the fields used to be a real hassle. Where there was no electricity, you had to run power lines, hundreds of meters long, and the voltage wasn't enough to power the pump. Where there was electricity, the electricity bill was more expensive than the water itself. Using a diesel engine was even more troublesome—queuing to buy fuel, carrying buckets back, the machine roaring, the fumes choking you, and by the end of the day, your ears were ringing and you smelled of diesel.

Then someone told you that you didn't have to go through all that trouble. You just set up a few planks at the edge of the field, put the pump in the well, lay the pipes in the ground, and leave the rest to the sun. As soon as the sun comes out, the water starts flowing; the stronger the sun, the more abundant the flow. No power lines, no diesel fuel, and you don't have to worry about a thing.

You've calculated the money saved. No more diesel fuel, no more electricity bills, no more queuing for gas, and no more hassle of repairing the machine. Over a year, that's enough to buy several bags of fertilizer; over a few years, enough to buy a new farm machine. But what brings you the most comfort isn't the money, but the ease—no more worries about energy, no more anxieties about power.

The sun rises every day, and water is delivered every day. It might be slower on cloudy days, faster on sunny days, but there's always sunshine and water. Standing at the edge of the field, looking at those pumps, you feel they're more reliable than anything else. They don't eat, they don't sleep, they don't complain, they work tirelessly for decades.

No need for power lines, no need to buy diesel fuel; sunshine is enough to deliver water to the fields. The sun understands this, the machines understand this, and now you understand it too.
