Battery electric vehicles only run on electricity, while plug-in hybrids incorporate a small internal combustion engine that recharges the battery or directly powers the wheels to improve driving range. Fuel cell electric vehicles convert hydrogen gas fuel into electricity.
Given the vastness of the universe, detecting alien life may require technological progress beyond the limits of what is sociologically viable and physically possible. Although interstellar civilizations are unlikely, messaging techniques and probes may improve the odds of successful communication with other intelligent life.
The "fediverse" is a league of like-minded apps looking to make our digital identities—including posts, followers, activity—move seamlessly between networks. It's a decentralized approach, making various social networks interoperable in contrast to Facebook and Twitter, where content is platform-specific.
