River Current Never Rests – Retrofitting Urban Infrastructure for Hydrokinetic Power

There are roughly 600,000 bridges in the United States alone. A large portion of them cross rivers. Every one of those rivers moves water through city centers, industrial zones, and residential districts, 24 hours a day, without stopping. The concrete piers holding those bridges are already sitting in that current, splitting it, generating turbulence, and…

The Electromagnetic Spectrum: Solar Energy Beyond Visible Light

In the Atacama Desert in northern Chile, the average annual irradiance exceeds 2,500 kilowatt-hours per square meter. No other inhabited landmass receives more solar energy per unit of ground. The panels installed across those high, dry plateaus face conditions that most solar engineers only ever model in software. And even there, at the most favorable…

The Science of Energy Conversion Efficiency

In 2016, a power plant in Bouchain, northern France, reported the highest heat-to-electricity conversion efficiency ever recorded for a commercial gas turbine installation. The plant, built around a GE 9HA gas turbine, hit 62.22 percent. Engineers had spent years refining every stage: combustion temperatures pressed close to the thermal tolerance of nickel-based superalloys, ceramic blade…
