Solar Cannonball

Solar-powered Cannonball runs represent the frontier of sustainable transportation records. Unlike electric vehicles that can recharge at stations, solar cars must generate all their energy from sunlight. This means strategic planning around daylight hours, weather patterns, and terrain. The challenge is as much about energy management as it is about driving — you can only move when the sun provides, and every watt counts. The gap between the purpose-built Sun Strider (13.6 days) and the production Tesla approach (57 days) shows how much vehicle design matters when your only fuel source is photons.
