What they cover
Real Engineering (Brian McManus) produces deep engineering analysis of infrastructure, energy systems, and technology. Climate-relevant content covers the engineering behind offshore wind, nuclear power, grid storage, sustainable aviation fuel, and green hydrogen. The channel uses detailed animations, real-world data, and engineering calculations to explain how systems work and where they face physical limits.
Why they matter
Real Engineering brings a level of quantitative analysis that most climate content lacks. McManus calculates energy density, cost per kilowatt-hour, material requirements, and engineering feasibility for every technology he covers. This rigor separates genuine solutions from hype. When he says a technology is viable, you can trust the math. When he says it faces fundamental scaling problems, he shows you the calculations.
