In this exciting experiment, we explore the concept of using elastic rubber to store mechanical energy, turning it into a Lego-powered 'battery.' By releasing the stored kinetic energy ...

This is similar to shooting an arrow with a bow. When you draw the bow, you store elastic energy. Upon the release of the arrow, that elastic energy is transformed into kinetic energy – movement.

Biomass is an abundant renewable resource in Nigeria. Comprising crop and animal residues, manure, charcoal and wood, it accounts for about 80 per cent of Nigeria’s total primary energy consumed.

Researchers developed a nano-spring coating with carbon nanotubes on battery electrodes to absorb strain, prevent cracks, and ...
