A new innovative irrigation system called Airdrop, that literally pulls water from dry skies, has won this year’s James Dyson Award. The Airdrop irrigation system is a low-tech, self-sufficient, solar-powered atmospheric water harvesting technology developed through working with irrigation manufacturers and local farmers.
It has been designed by Swinburne University of Technology student Edward Linnacre, making it the second year in a row an Australian design has won the James Dyson Award. Watch the video after the jump to learn how the low-tech irrigation system works.
How the Airdrop System Works
Within the Airdrop system, a turbine intake drives air underground through a network of piping that rapidly cools the air to the temperature of the soil where it reaches 100% humidity and produces water. The water is then stored in an underground tank and pumped through to the roots of crops via subsurface drip irrigation hosing. This method ensures that water is delivered directly to the plant roots, minimizing evaporation and maximizing efficiency.
The Airdrop system is particularly beneficial in arid regions where traditional water sources are scarce. By harnessing the moisture present in the air, even in dry climates, the system provides a sustainable solution to water scarcity. The technology is not only innovative but also environmentally friendly, as it relies on solar power to operate, reducing the need for external energy sources.
Benefits and Potential Applications
The Airdrop irrigation system offers numerous benefits beyond its primary function of water harvesting. For instance, it can significantly reduce the dependency on groundwater and surface water sources, which are often over-exploited in agricultural regions. This reduction can help in preserving natural water reserves and maintaining ecological balance.
Moreover, the system’s low-tech design makes it accessible and affordable for small-scale farmers who may not have the resources to invest in high-tech irrigation solutions. Its self-sufficiency means that it can operate in remote areas without the need for extensive infrastructure, making it ideal for use in developing countries where water scarcity is a critical issue.
The Airdrop system also has the potential to be adapted for various scales of agricultural operations, from small family farms to larger commercial enterprises. Its modular design allows for easy expansion, enabling farmers to scale up their irrigation capacity as needed.

The success of the Airdrop system highlights the importance of innovative thinking in addressing global challenges such as water scarcity. By leveraging natural processes and renewable energy, the system provides a sustainable and practical solution that can be implemented worldwide. As climate change continues to impact water availability, technologies like Airdrop will become increasingly vital in ensuring food security and supporting agricultural productivity.
