A "crackpot" design

Hawaii? Alaska? Antarctica? It is only the suburbs.

Our super Crackpot project for the future: building and using a solar sail in order to travel our solar system, to reach the eighth and most distant planet in our solar system, and also the windiest: Neptune. We expect achieving high energy generation by using the solar sail as a kite by 580 m/s maximal wind speed. We hope that this is far enough away so that no one can challenge the results.

Hydrogen and helium would be used for balloons.

Maybe we could set a record for winding the furthest self-winding watch from the sun!
