Thousands of people get lost in the desert every year, but these otherworldly solar beacons could save them
They look like save checkpoints in a video game, and they kind of are.
Solar-powered beacons in the Saudi Arabian desert guide lost travelers to water.
Chief among my worries as a kid was what I considered the high probability that at some point in my life I would be trapped in quicksand. It felt extremely important that I remember all the tricks and techniques for getting out — just in case! A close second would have to be getting lost in the desert and dying of dehydration. You absolutely had to watch out for those deadly mirages, where the light on the horizon bends in such a way that you're certain you can see water up ahead.
At least one of those fears was fairly well-founded. All jokes aside, the desert is an incredibly dangerous place. It turns out that thousands of people get lost and go missing in deserts across the world every year. The Sahara Desert, the largest hot desert in the world, claimed a staggering 8,000 lives alone in 2023. These aren't overly flippant explorers, for the most part. Many migrants fleeing conflict zones across the desert become lost and suffer a tragic fate while trying to navigate the 3.6 million square mile area. There are many things that make the desert deadly, but dehydration with no access to water is at the top.
A team in Saudi Arabia has been testing a new technology that could drastically reduce dehydration-related deaths in the country's Al-Nafud Desert, and it looks like something straight out of a video game.
Though the Al-Nafud desert is quite a bit smaller than the Sahara standing at about 25,000 square miles, it can still be daunting to cross. Most years, hundreds of people go missing with several dozen of them perishing in the process.
An explorer named Mohammad Fohaid Al-Sohaiman had a brilliant idea to help lost travelers find water. Having been rescued in the desert himself, even as an experienced survivalist and outdoorsman, he knew there had to be a better way.
“Many people lost their lives in the desert near water resources because they did not know that water resources were close to them,” he told Arab News.
The idea: Beacons made of laser light, shot directly into the sky near water sources such as water wells. These powerful lights could be seen from miles away and would be powered by solar panels, ensuring they never go dark.
The plan is to eventually install 100 of the beacons throughout the Saudi Arabian desert.
The program to install the life-saving beacons began in 2021. It's still getting attention and inspiring awe all over the world.
A recent viral Reddit thread highlighted the innovative laser lights, and users were impressed:
"Absolutely brilliant! The rest of the world should immediately begin to implement this system in their desert areas as well as open oceans where water, food and communication devices could be stored for boaters in distress."
"This is such an amazing idea."
Others joked to the beams look like "save points" or "checkpoints" in a video game. They're not wrong!
Some have criticized the beacons, however, claiming that the light pollution may harm the desert's natural environment and residents like nocturnal animals and insects.
The desert holds vast potential for solar power due to its massive open spaces and plentiful sunlight. In fact, solar farms are common in deserts all over the world.
However, there are a couple of limitations that stop us from covering all the world's deserts in solar panels and completely converting to solar energy.
First, people underestimate how destructive and harsh the desert environment really is. Sand is incredibly corrosive, especially when whipped around in high-powered sandstorms. Maintaining solar equipment in the desert is incredibly challenging and costly.
Second, we think of deserts as open wasteland, but that's a misnomer. They're actually incredibly biodiverse natural habitats, home to many different forms of plant, animal, bird, and insect life. The desert habitat is no less important to preserve than rainforests or oceans.
Third, while solar energy is generally considered incredibly eco-friendly, massive solar farms can actually put off quite a bit of heat. A desert-sized solar farm would emit so much heat that it could negatively contribute to global warming and have devastating effects.
In any case, the life-saving beacons are a genius idea and a fantastic use of solar technology. Once the program is fully rolled out, it could save dozens or even hundreds of lives every year.
Just imagine a similar operation conducted in the massive Sahara Desert, or even in remote stretches of the American southwest.
As one commenter stated perfectly, "Now this is the type of innovation for the future I can get behind."
