Roadbed tribological energy harvester.
Article in Science advances, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Roadbed tribological energy (RTE) is a promising recoverable resource with an estimated potential on the terawatt scale, generated annually by the interaction between tires and road surfaces. However, RTE remains underutilized due to the lack of effective energy harvesting technologies that can address its high-entropy characteristics. Here, we present a revolutionary harvester formed by a freestanding layer triboelectric nanogenerator array embedded in the road. The harvester effectively converts low-grade vibratory RTE into electrical energy. It demonstrates the potential to achieve a peak power of 16.409 milliwatts and an average power of 2.2 milliwatts from a compact 78-square centimeter road area under a single tire impact, with a triboelectric conversion efficiency of 11.723%. In addition, we developed a self-powered intelligent and connected transportation system (SP-ICTS), integrating a five-in-one harvesting array. Experimental findings show that the system can meet the SP-ICTS's electricity requirements along a 1-kilometer segment with a 50-meter harvester.
