Here is an ingenious technique to irrigate plants and save a lot of water!

Water is a precious resource and is becoming increasingly rare, which is why not wasting it has become a priority which no one can afford to ignore. 

Much of the water that is used for cultivation is wasted as it evaporates due to the sun, but today we are going to show you a more sensible and economical irrigation technique: solar drip irrigation.

The goal is to provide an efficient and simple system to install, that favors an increase in production while decreasing significantly water wastage. 

Solar drip irrigation, which thanks to its accessibility is used both in agriculture and for domestic use, employs the energy of the sun as the motor of the movement and distillation of water.

In addition, the system allows for obtaining distilled water; optimal for plants.

Setup could not be simpler: a normal plastic bottle cut in half, topped by a much larger bottle, also cut in half.

The smaller container is always kept full of water.

The two bottles are simply placed on the ground, near the plants to be irrigated; the hay helps to keep moisture in the ground.

The sunrays heat the water in the bottle. The water evaporates but, because of the larger bottle, the water drops cannot escape so they drip into the soil, irrigating it.

Thus, the evaporation of moisture into the air is practically nil and, not least, the plants are irrigated with distilled water.
