That&#x27;s why i said blimps are the way to go.
Lifting body also has it&#x27;s limit, at the end solar just can&#x27;t provide enough thrust for heavy lifting, if the lifting it self is done through other means such as buoyancy then it&#x27;s not an issue as solar can provide enough thrust for actually going forward as well as power the compressors to control the buoyancy of the craft.<p>Anything that will be dependent on aerodynamic lift alone literally won&#x27;t be getting of the ground with any significant payload.
