Organic electronics, or "polytronics," using electrically conductive plastics, offer advantages like replacing rare materials and reducing CO2 emissions. Polytronics apply carbon-based components in thin layers on flexible substrates, providing wider applications and material savings. For example, ...

Solar airships have the potential to provide environmentally friendly long-distance travel. These airships would be powered by solar cells on their outer skin and lightweight batteries on board, resulting in virtually no harmful emissions. The large surface area of airships provides ample space for...
