WebApr 12, 2024 · Here, we propose and experimentally realize a photon-recycling incandescent lighting device (PRILD) with a luminous efficacy of 173.6 lumens per watt (efficiency of 25.4%) at a power density of 277 watts per square centimeter, a color rendering index (CRI) of 96, and a LT70-rated lifetime of >60,000 hours. WebJul 12, 2024 · As a result, the efficiency of the fuel cell skyrocketed from below 15% to 60%, he and his colleagues reported last year in Energy & Environmental Science. The result has since improved to 70%, MacFarlane says—but with a tradeoff. The ionic liquid in his fuel cell is goopy, 10 times more viscous than water.
