PlanetWEST Introduces its “No Harm” Delivery Truck Concept
A large fleet of delivery trucks equipped with PlanetWEST's MIDAC (Mobile Intelligent Direct Air Capture) system could collectively process an enormous volume of atmospheric air each year. Based on fleet size, vehicle operation, and daily driving routes, a distributed network of MIDAC-equipped vehicles could process hundreds of cubic miles of atmosphere annually.
The concept highlights an important intersection between two different environmental strategies: emissions prevention and active atmospheric cleanup. While transitioning transportation away from combustion can prevent new emissions, MIDAC is designed to address pollutants that are already present in the atmosphere.
PlanetWEST's MIDAC system is designed as a distributed, mobile direct air capture network. Rather than relying exclusively on massive, energy-intensive stationary facilities, the technology can be integrated directly into the cooling and airflow systems of moving vehicles.
As a truck travels its daily routes, ambient air naturally moves through the vehicle's front grille and cooling system. MIDAC is designed to leverage this existing airflow to filter targeted pollutants—including black carbon (soot), PM2.5, and other fine particles—capturing solid carbon at street level where pollution concentrations can be highest.
This creates the possibility of transforming ordinary vehicles into distributed atmospheric cleanup platforms.
Emissions Prevention vs. Atmospheric Cleanup
The environmental impact of a MIDAC-equipped vehicle depends in part on its powertrain.
Combustion-Powered Trucks: Source Capture + Ambient Cleanup
When MIDAC is installed on existing diesel or other combustion-powered trucks, the system can function as both a source-capture mechanism and a mobile ambient air filter.
The vehicle can help capture black carbon and particulate matter generated by its own operation, while simultaneously filtering pollutants already present in the surrounding environment—including emissions from nearby traffic and other combustion sources.
In this configuration, MIDAC provides an opportunity to address pollution while transportation systems continue their transition toward lower-emission technologies.
Zero-Emission Trucks: Pure Ambient Cleanup
Electric vehicles have no tailpipe emissions, making them an especially interesting platform for mobile atmospheric cleanup.
When a zero-emission vehicle is equipped with MIDAC, it can travel through urban environments without generating tailpipe CO₂, black carbon, or PM2.5 while actively filtering pollutants already present in the surrounding air.
The result is a fundamentally different transportation model: vehicles that not only avoid adding certain pollutants to the atmosphere, but potentially remove existing particulate pollution as they travel.
The volume of air processed by a vehicle depends on factors including its frontal surface area, speed, operating schedule, airflow, and cooling-system design. Across a large commercial fleet operating continuously throughout cities and major transportation corridors, those individual volumes can accumulate into a substantial atmospheric footprint.
A distributed network of MIDAC-equipped vehicles could therefore target pollution hotspots across dense urban areas, logistics corridors, ports, industrial districts, and other locations where particulate concentrations can be elevated.
Black carbon is particularly significant because it is a powerful short-lived climate pollutant. Removing black carbon and other fine particulate matter can potentially provide both climate and public-health benefits, particularly when pollution is captured close to ground level and near population centers.
The Takeaway
The transition to cleaner transportation is an essential component of reducing future emissions. But preventing new pollution is only one part of the challenge.
PlanetWEST's MIDAC concept explores a complementary approach: actively removing existing particulate pollution while vehicles are already moving through the environments where that pollution is concentrated.
Instead of viewing transportation solely as a source of emissions—or simply as a system that must be electrified—MIDAC proposes a new possibility: vehicles that can become part of a distributed atmospheric cleanup network.
From delivery fleets and commercial trucks to municipal vehicles and other high-mileage transportation platforms, mobile air capture could provide a scalable way to bring atmospheric cleanup directly to the places where it is needed most.
