Artificial Intelligence and a blast of steam are all this machine needs to wipe out weeds in your yard — without using a single drop of chemicals.
Mark Boysen, an inventor from Edina, Minnesota, built a device that’s turning heads by combining cutting-edge technology with a genuine concern for the environment. The interesting part is that the foundation of his invention is surprisingly familiar: he transformed a regular lawn mower into a device capable of eliminating unwanted plants in a clean and precise way.
The idea sounds simple, but the technology behind it is pretty sophisticated: the machine uses AI to identify each weed, distinguishes it from the surrounding plants, and then fires a precise blast of steam directly at the problem.
Results show up in about 20 minutes — and the only ingredient involved is water, 100% pure.
That is sustainability in action, without sacrificing efficiency. 🌱
How the Machine Actually Works
The technology Boysen developed combines two elements that, together, form a pretty clever solution to a very old problem. The artificial intelligence built into the equipment was trained to recognize visual patterns of different types of weeds, allowing it to precisely determine which plants need to go and which ones should stay. That level of discernment is what sets this approach apart from any traditional method, where chemicals are sprayed indiscriminately across the entire treated area, even harming the plants you actually want to keep healthy.

In the inventor’s own words: we can detect the weeds with AI, distinguish the difference between a weed and what is not, and we hit it with a blast of steam, which kills using just water, and it eliminates the weed in about 20 minutes, Boysen explained.
Once the AI identifies the target, the superheated steam system kicks in. The equipment directs a jet of hot water straight onto the unwanted plant, hitting the weed’s cellular structure and causing it to break down permanently. The precision of this process is critical: the steam acts exactly where it needs to, without spreading chemicals across the area. Within roughly 20 minutes, the weed already starts showing the first signs that it won’t survive the treatment.
One fun detail that Boysen himself likes to point out is the smell that shows up during the process. According to him, they will be dead in about 20 minutes. You smell it, it will remind you of spinach, and that is the weed cooking. Basically it is the cellular structure breaking down. In other words, you can tell the machine is working just by the aroma. 😄
From Product Coach to Sustainable Inventor
Before founding his company, NAWARE, Boysen spent 12 years working as a product coach, helping companies of all sizes develop products. He worked with everyone from small startups to giants that rank among the largest corporations in the world, teaching them how to structure and launch new products.
It was precisely that background that motivated him to build something himself. I was teaching companies and corporations, from startups to companies at the top of the list of the biggest on the planet, how to basically build products. And then I thought: maybe I should follow my own playbook, now is the time to develop something, the inventor shared. That shift is a great reminder that sometimes the people who spend years guiding others also have big ideas waiting to come to life.
The invention has already paid off for Boysen. He secured a patent for the equipment, entered the project in the Minnesota Cup competition last year, and even took home the sustainability award from Minnesota’s pollution control agency. Recognition that speaks to the real potential of the solution.
Why This Matters for Sustainability
The environmental impact of conventional herbicides is something scientists and researchers have been debating for decades. Chemicals used to kill weeds can contaminate the soil, seep into groundwater, and affect the entire ecological chain around treated areas. Boysen’s machine completely eliminates that variable, since the only input it uses is water, transformed into steam by the equipment itself.
Sustainability here is not just a nice-sounding concept on the product packaging. It shows up in a concrete way in every aspect of how the technology works. Without chemical residues in the soil, the natural fertility of the ground stays intact. And without the need to buy, store, and dispose of herbicide containers, the whole process generates far less waste. For anyone already adopting more conscious habits in their daily life, this machine represents a real and tangible step in that direction.
That focus on safety makes a huge difference for people with families. Ryan Finnefrock, Boysen’s neighbor and father of two young children — a four-year-old and a seven-month-old — explained why the chemical-free approach matters so much to him. There are a lot of products out there that do the job and are very effective, but are they the best for kids? We do not know, Finnefrock said. We know that steam is not going to hurt anything. So it is amazing that he came up with this idea and grew it.
Beyond that, it is worth looking at the bigger picture this invention fits into. Solutions that combine artificial intelligence with natural methods of weed control represent exactly the kind of innovation that can help both residential gardens and larger properties evolve without harming the environment. Boysen’s technology might seem small in that context, but it is exactly this kind of scalable solution that, when adopted on a large scale, has the potential to drive meaningful change. 🌍
Artificial Intelligence Applied to the Real World
One of the most fascinating things about this technology is how it shows that artificial intelligence does not have to live inside corporate servers or smartphone apps to make a difference in people’s lives. Here, it is embedded in a physical piece of equipment, operating out in the open, dealing with variations in light, soil, weather, and the huge diversity of plant species that can pop up in the same yard. Training a computer vision model to that level of accuracy takes serious refinement, which shows there is careful technical work behind what looks like a simple solution.
The AI powering this machine was trained to recognize different types of weeds under different conditions. This machine learning process allows the system to confidently apply what it has learned to brand-new situations it has never encountered before. It is that power of generalization that makes the solution work in the real world, where conditions are rarely ideal and surprises happen all the time. The robustness of the model is just as important as the accuracy of the steam blast, because a wrong identification could damage plants that should be protected.
Boysen’s company, NAWARE, has already developed a smaller version of the machine, designed to be more commercially viable for homeowners who want to keep their yards chemical-free. For now, he chose not to reveal all the details about the new model, saying it is not ready for its official public debut just yet. One version of the invention is already in operation at a vineyard in Arizona, and Boysen even presented his sustainability-focused work at the traditional Minnesota State Fair.
Interest in the product has been so strong that demand already exceeds what he can deliver. We have more demand than we can handle, honestly. It all comes down to how fast I can develop the product from here, the inventor revealed.
This kind of practical application of artificial intelligence is what really fires up the imagination of anyone following the tech space. This is not an AI generating text or images — it is a system that interacts with the physical world, makes decisions in fractions of a second, and delivers measurable, immediate results. The combination of machine learning, robotics, and a commitment to sustainability points toward a future where the tools we use every day will be increasingly smarter, more efficient, and more respectful of the environment around us. 🤖
