Possibility of Building an Electric Plane: Starting from Existing Designed Models

Entering the 21st century, searches for alternative energy have become more and more significant to mitigate the gradual deterioration of the environment and the dearth of fossil fuels such as petroleum. As a result, plenty of scientists start resorting to electricity, one kind of clean energy produced by natural power like wind and water. Electricity has recently been applied to vehicles after decades of research, and the technology of the application doesn’t stop progressing. However, the application on vehicles is not just a destination but a starting point for electric aircraft. Nowadays, the research of electric aircraft has been started by several companies. This review begins with the rapid development of new energies, summarizes current existing models of electric aircraft from Airbus, Boeing, and other companies and agencies, considers the possibility of electric aircraft, and provides the prospect of building an electric aircraft in the future. The review concludes that while building electric airplanes is possible, and the size is restricted to be small enough due to the restriction of the energy density of the battery.
