Yes, integrating an energy capture device is not optimal for many/most use cases. A vehicle operating within civilization is better served by having means to receive and store energy. Of energy storage mechanisms, chemical seems more advantageous than kinetic or pressure. From there the question becomes one of ionic or covalent. Covalent has a higher energy density, which is why tanks of hydrocarbons are so ubiquitous.
