Nanotechnology mimics plant photropism to provide efficient solar energy collection. Imagine your roof covered in tiny sunflower-like solar collectors that provide all the energy you need to run your ...

One of the most remarkable capabilities of living things is phototropism—in which living organisms track and move with light sources. The most familiar example of this phenomenon is flowers that move ...

Many plants can orient themselves toward a light source to maximize the energy they absorb. Young sunflowers, for example, tilt their heads to follow the sun throughout the day, a result of their ...

Solar panels could be made from rows of tiny artificial sunflowers, which automatically bend towards light. Each artificial sunflower, known as a SunBOT, consists of a stem made of a material that ...
