Where Science Meets Fiction
Understanding sustainability science.
When the Bullitt Center opened on Capitol Hill in Seattle in 2013, its designers published something most architects never bother with: a full accounting of the carbon embedded in the building before anyone arrived for work. The concrete, the steel, the glass, the insulation – all of it together represented approximately 1,800 tonnes of CO2…
Inside a hollowed-out mountain in northern Wales, 1.7 million cubic metres of rock were excavated over ten years to create one machine. Dinorwig power station, completed in 1984, sits inside Elidir Fawr and looks from the outside like nothing more than a service entrance cut into slate. Inside, its turbines can go from standby to…
In the Energinet control room in Fredericia, the operators running Denmark’s national grid watch a dashboard that updates every five seconds. On a January morning in 2023, wind output on the western interconnect jumped from 3.1 to 4.7 gigawatts in under an hour. The export schedules to Norway and Germany had already been adjusted. The…
In Ulaanbaatar in January, the temperature drops to minus thirty Celsius and the city burns coal. Not just in power plants. The ger districts, traditional felt-tent neighborhoods covering a third of the city, run individual household stoves through the night because stopping means freezing. The smoke has nowhere to go. A thermal inversion layer, cold…
In 2018, the city of Shenzhen finished something no city had managed before. Its public bus fleet, all 16,359 vehicles, had completed a full transition to electric power. Every bus leaving the Longhua depot each morning did so without a combustion event. The fleet covered roughly 1.2 billion kilometres annually and had previously been one…
Bitterfeld-Wolfen sits in the Saxony-Anhalt region of eastern Germany. For most of the twentieth century it was one of the most productive chemical manufacturing zones in Europe, producing dyes, pesticides, chlorinated solvents, and plastics at industrial scale. By the 1990s it was also one of the most contaminated places on the continent. Chlorinated compounds, heavy…
A 2,000-tonne fermentation tank in Blair, Nebraska is filled with something that looks like thin gruel. Corn steep liquor, the aqueous slurry left after wet milling separates starch from the kernel, sits in the tank at 40 degrees Celsius while a carefully managed culture of Lactobacillus bacteria converts dissolved sugars into lactic acid. The process…
In the autumn of 2022, a procurement team at a Tier 1 automotive supplier in Stuttgart spent three weeks trying to replace a single part. The component was a structural bracket inside a door panel. It weighed 340 grams and was currently made from glass-fiber-reinforced polypropylene. The team had been asked to find a bio-based…
In Merseburg, a city in Saxony-Anhalt in central Germany, a facility operated by APK AG runs an unusual version of plastic processing. The mixed polyethylene films entering the plant are not melted and extruded, as conventional recycling does. They are dissolved. A purpose-designed solvent separates the polymer chains from their contaminants, isolates the pure material,…
In 2007, a research team at UC Berkeley put a sample of green sulfur bacterium into a laser spectrometer and watched energy move through its photosynthetic machinery in real time. The bacteria had been collected from an anoxic sulfur spring. The experiment was designed to measure how quickly an absorbed photon transferred its energy from…
Kalimantan, Indonesia. October 2019. Underground peat fires have been burning for weeks across an area the size of Belgium, most of them invisible at ground level. The smoke rises but the fire front does not. Aerial surveillance finds only haze. A ground crew moving into the forest walks over active combustion without knowing it, because…
CO2 storage gets judged in seconds during a damp morning walk, when a white cloud pours upward and the gut reaction says pollution. Carbon capture and storage moves CO2 into long lived confinement, so visible steam rarely tracks climate impact. More cloud does not equal more carbon. Misreading cues risks wrong conclusions, while clear interpretation…
Basics of Photosynthesis in sustainable energy meet reality when balcony plants glow in harsh sun while rooftop monitors show modest power. Photosynthesis is the way living surfaces turn sunlight into stored chemical energy instead of instant output. Many people assume stronger glare on leaves or panels means stronger energy gains, yet more light does not…
