Electrical engineers and microbiologists have created a device they call an 'Air-gen.' or air-powered generator, with electrically conductive protein nanowires produced by the microbe Geobacter. The Air-gen connects electrodes to the protein nanowires in such a way that electrical current is generated from the water vapor naturally present in the [...]

Fuel cells turn chemicals into electricity. Now, an engineering team has adapted technology from fuel cells to do the reverse: harness electricity to make valuable chemicals from waste carbon (CO2). [...]

The need to efficiently harvest solar energy for a more sustainable future is increasingly becoming accepted across the globe. A new family of solar cells based on perovskites -- materials with a particular crystal structure -- is now competing with conventional silicon materials to satisfy the demand in this area. [...]

Many greenhouses could become energy neutral by using see-through solar panels to harvest energy - primarily from the wavelengths of light that plants don't use for photosynthesis. [...]
