This "world's smallest electric vehicle" is unlikely to be maneuvered by humans. It is very small and is a structurally special molecule that starts to move forward when it receives current, but it travels in nanometers. Calculations.
This molecule has a "spindle" in the middle, with two similar wheels on both the front and rear. If the molecule is touched with a particularly small probe and supplied with current, the four "wheels" will begin to rotate, driving the entire molecule forward. Tests performed on the surface of the copper panel on this electric vehicle show that it can advance 6 nanometers if it is applied 10 times. However, this is an experiment in the low-temperature and high-vacuum environment of minus 200 degrees Celsius, which is still a difficult problem in the conventional environment.
Due to Outside Wall Extruded Polystyrene Board excellent high strength, compression resistance, excellent thermal insulation, light texture, easy to use, high-quality hydrophobicity, damp-proofing and environmental protection performance, stability and corrosion resistance, Yu Ou Nuo exterior wall extruded board has become a new building material widely promoted in the construction industry. It is widely used in wall and floor insulation.
