The Problem
- The United States has 7 million miles of power lines – enough to go to the Moon and back 14 times.
- >50 % of power flows through transformers ≥30 years old, the age at which failures become common.
- Power‑line conductors are bare metal (4 kV–765 kV) on ceramic insulators, usually mounted on wooden poles.
- When wood rots or a cotter pin fails, a live conductor can fall onto a dead tree on a windy day, sparking catastrophic wildfires (e.g., the Palisades Fire in LA, 2022).
Current Inspection Methods
| Method | Cost / Limitations |
|---|---|
| Foot patrols | Linemen inspect 50‑150 poles/day. Small rural co‑ops (~20 employees) own ~50 k distribution poles → ≈10‑year inspection interval. |
| Helicopters | $25 k per flight; high fatality risk. |
| Satellites | Insufficient millimeter‑level precision. |
| Drones (existing) | Limited by battery life and BVLOS regulations. Utilities often send pilots in trucks to collect data. |
| Commercial “drone‑in‑a‑box” (Skydio, DJI) | One‑drone concurrency, expensive (≈$250 k/box), range ≈15 mi, not scalable. |
Result: Drones are the most promising solution, but current implementations don’t scale to the size and ruggedness required for utility networks.
Our First Attempt (Why It Failed)
- Goal: Harvest power inductively from the magnetic field around power lines using a split‑core current transformer clamped to the conductor.
- Outcome: Successfully recharged a few batteries in the field after ~4 months of development (proof‑of‑concept).
Show‑stoppers
- Insufficient current on distribution lines – need ~1 MW (≈1 000 homes) to charge a drone at useful rates.
- Risk‑reward mismatch – utilities already use permanent inductive sensors (e.g., Heimdall Power “Neuron”). Landing a drone repeatedly on many points is deemed too risky.
Rethinking the Architecture
Instead of expensive, over‑engineered boxes protecting fragile drones, we flipped the paradigm:
- Ultra‑rugged drones that can survive months outdoors.
- Cheap, attritable charging stations (a few thousand dollars each).
What We’re Building Now
-
Weather‑hardened, long‑range fixed‑wing drones
- Range: >70 mi per flight
- Endurance: months of outdoor operation
-
Inductive charging pads (no connectors or moving parts)
- Cost: ≈$2 k per pad
- Deploy a few pads along a transmission corridor; drones hop between them.
- Coverage estimate: 1 000–5 000 pads could span the continental U.S.
-
Data backhaul via the charging station
- Drone offloads terabytes of LiDAR / high‑res imagery to a local SSD over high‑speed Wi‑Fi.
- Station pushes data to the cloud via Starlink, LTE, or fiber asynchronously, freeing the drone for the next mission.
Key Benefits
- Eliminates battery‑swap logistics and BVLOS constraints.
- Enables reactive inspections (e.g., harmonic detection, post‑storm scans) within minutes.
- Reduces reliance on costly, slow‑moving contractor crews.
Potential Markets
| Sector | Why It Matters |
|---|---|
| Power utilities (primary) | Faster, cheaper, safer inspections; real‑time fault detection. |
| Telecom | Inspecting fiber‑optic and microwave tower corridors. |
| Rail | Monitoring right‑of‑way vegetation and infrastructure. |
| Oil & Gas | Pipeline integrity checks. |
| Forestry | Health assessments, fire‑risk mapping. |
| Search & Rescue | Rapid deployment in remote terrain. |
| Agriculture | Large‑scale field scouting, irrigation monitoring. |
Note: We are committed to responsible use; we do not support a surveillance‑state application of our technology.

Overview
Aging weaponized, and examples of government overreach are numerous (case in point: Sonoma County, California spying on landowners). We have zero interest in supporting uses like this.
Our Backstory
Ronan has always had an unhealthy obsession with flying machines, from designing remote‑controlled planes growing up, to building eVTOL tech for DARPA and the Air Force while still a university student.
Warren and Ronan met during a startup competition with a UAV solution in agriculture.
Hayden, a childhood friend of Ronan, was deeply ingrained in the power‑utility space and realized the true pain point there.
Shortly after graduating, Ronan, Hayden, and Warren quit their jobs to take the idea full‑time in the summer of 2025.
Around the same time, Avi dropped out of college, bringing sales skill and regulatory expertise as our fourth co‑founder.
Recent Milestones
- First major contract secured – we are finalising pilot details with several large utilities.
- First paid flight scheduled for mid‑April.
- Business model: Inspection‑as‑a‑service, charging per pole or tower.
Request for Feedback
We are very interested in your opinion! If any of you work in the energy industry and know a thing or two about infrastructure inspections, we would love to learn from you. All feedback—good or bad—is welcome.
