The air around your home is 78% nitrogen — the same nutrient you've been buying in bags for years. AirFeed captures it, converts it to liquid plant food, and delivers it straight to your garden. No store runs. No bags. No spreading. Ever again.
Technology in development. Specifications below reflect intended design pathway and target performance. Patent pending — four U.S. provisional patent applications are on file with the USPTO (see Patents). Provisional applications do not constitute issued patent protection.
Plants need nitrogen to grow. Air is almost entirely nitrogen. The problem was always getting it from up there to down here — in a form plants can actually use. AirFeed solves that, for the first time, at the scale of your backyard.
AirFeed has no moving parts, no electricity requirement, and no ongoing chemistry you need to manage. Here's what the device is actually doing, in plain language.
The device has air intake slots along the top of its housing. On humid days — mornings, evenings, after rain — moisture-laden air drifts naturally through the device. No fan required. The more humidity in the air, the more the device has to work with.
Before the air reaches the main catalyst, it passes through a surface conditioning mesh coated with humic acid and potassium silicate. This layer does two things: it makes the surface more attractive to water vapor (helping moisture condense out of the air), and it begins delivering potassium and silicon into the liquid that forms on the mesh surface.
This is the core of what makes AirFeed different from anything else in your garden center. The second mesh layer is coated with an iron-based catalyst that breaks apart the nitrogen molecule (N₂) — normally one of the most stable and difficult molecules to crack — at room temperature and ambient pressure.
In industrial fertilizer manufacturing, that same nitrogen-cracking step requires reactors running at 500°C and 200 times atmospheric pressure, burning natural gas. AirFeed's intended design pathway achieves the same result at the ambient conditions outside your back door.
As ammonia forms in water droplets on the mesh surface, it runs down into the sealed collection vessel below. The reservoir is where the liquid becomes a complete plant food — because sitting at the bottom is an AirFeed Pellet.
A standard ¾" garden hose adapter at the base of the device lets you connect directly to your existing hose or drip irrigation system. Draw what you need, when you need it. There's no mixing, no measuring, no sprayer to clean up afterward — just a reservoir of ready-to-use liquid plant food sitting outside your back door.
AirFeed has no circuit board, no motor, no timer. It's a system of two specialized mesh layers and a reservoir — each with a distinct, complementary function.
Attracts atmospheric moisture, begins nutrient delivery. Stainless steel mesh substrate coated with humic acid and potassium silicate.
The core of the device. Intended to convert N₂ from the air into ammonia (NH₃) at room temperature. Iron oxide catalyst with Nafion proton-exchange coating.
Collects the liquid from the meshes. The 30-day dissolving Pellet adds phosphorus, magnesium, and trace minerals to round out the nutrient profile.
The combination of the conditioning mesh, catalyst mesh, and the 30-day Pellet is designed to address all major plant nutrient categories. Here's what comes out of the reservoir, and where it comes from.
"This sounds like a magic box — nitrogen doesn't just come from air."
Nitrogen does come from air — always has. Air is 78% N₂. The challenge has always been fixing it: breaking the N₂ triple bond and converting it to a plant-usable form. Industrial fertilizer does this in massive high-pressure reactors. AirFeed's intended design pathway achieves it on a catalyst mesh at the conditions outside your back door.
"It must use a lot of electricity to do this."
The base AirFeed model uses zero electricity. The catalyst mesh operates passively — driven by humidity and natural airflow. The BoltBrew model adds 50W solar power to enhance nitrogen fixation rate for drier climates, but the passive AirFeed requires no power connection whatsoever.
"If it worked, someone would already be selling it."
Academic groups at Stanford, Eindhoven University, and MIT have all published research demonstrating ambient-condition nitrogen fixation on catalyst surfaces. What hasn't existed — until now — is a consumer-deployable product built around this chemistry. That gap is exactly what C&C's Fertilizer is designed to close.
"What if it doesn't rain? Does it stop working?"
AirFeed works on atmospheric humidity, not rainfall. Even in relatively dry climates, there's enough moisture in the air to run the reaction — output scales with local humidity rather than stopping when there's no rain. The BoltBrew model with active plasma discharge is designed for lower-humidity environments like the Southwest.
