Brendan Carroll

Hey! I'm Brendan. I live between Limerick/Ireland and Hamburg/Germany. I'm CEO/Founder @ EpiSensor (IoT Infrastructure for the energy transition) and SuperDangerous (AI stuff). I like surfing, building and writing (traditionally software, mostly just English these days). You can get in touch with me on X, LinkedIn, GitHub or by .

Notes

50x LeverageJanuary 2026 AI can deliver dramatic leverage in specific conditions. The hard part is knowing where it is real. 480k Feeds of DataJanuary 2026 Why Zigbee beats LoRaWAN for dense commercial buildings and how EpiSensor unifies the data layer. Electricity to MoneyJanuary 2026 Rising AI electricity demand will increase grid pressure, making flexible load orchestration strategically important. The Aliens Have Already LandedDecember 2025 AI is alien technology. We don't yet know if it will teach us secrets of the universe or harvest our innards. Founderless and VClessDecember 2025 AI does not remove startup risk, but it can reduce the cost of getting to real market evidence. InterstellarDecember 2025 Gauging AI adoption across the industry and making peace with the pace of change. Choose ProgressJuly 2025 Everything is either energy constrained or intelligence constrained. Solar PV and AI are changing that. Our Fusion Reactor in the SkyMay 2025 Silicon, solar, and intelligence — the cosmic puzzle nearing its solution. Bitcoin Mining and RenewablesOctober 2024 Excess solar PV needs a customer. Bitcoin mining ASICs colocated with renewables might be the answer. Hit Climate Targets by Building the TechOctober 2024 Data centres and other flexible loads can help grids absorb renewable intermittency during the transition. What Happens When the Grid Drops a GigawattOctober 2024 A bedtime story about grid frequency, interconnectors, and why IoT infrastructure matters for the energy transition. If AI Progress Stopped Right NowSeptember 2024 Intelligence has been a limiting factor in many systems problems. AI lowers that constraint, but execution still matters. LoRaWAN is the wrong tech for dense sensor networks in buildingsSeptember 2023 Great range, wrong trade-offs. LoRaWAN cannot handle dense building data or reliable OTA firmware updates. Solar and Batteries Will Win the RaceSeptember 2023 Solar and storage will win. The missing piece is IoT infrastructure that makes assets aware of grid conditions. People Serious About Software Should Make Their Own HardwareOctober 2021 Energy management needs a 10x improvement. That requires vertical integration of hardware and software.
