Solar power is now the cheapest source of electricity in history, according to a 2020 report by the International Energy Agency. But there's something holding this clean energy powerhouse back: space. Unlike fossil fuel power stations, solar farms need a lot of room to generate enough electricity to keep up with demand. Most solar farms are composed of ground-mounted panels that take up land that could be used to grow food or provide habitat for wildlife.

Biology
Generally, tendon injuries are caused due to trauma or gradual wear and tear from overuse or aging. Structurally, tendons—as well as their associated extracellular matrices—are comprised of nanostructured materials. Scientists have been focusing on tendon-bone healing using nanotechnology.

Electric aircraft have gained increasing attention in recent years due to their potential for environmental and economic benefits over conventional airplanes. In order to offer competitive flight times and payload capabilities, electric aircraft power systems (EAPS) must exhibit extremely high efficiencies and power densities. While advancements in enabling technologies have progressed the development of high performance EAPS, further research is required.
