Portable, durable, integrated solar power generation device

This is a portable solar power device designed to follow the sun. It uses a light sensor to independently adjust multiple motors, ensuring its solar collector is always pointed at the sun. Curved mirrors are positioned around the collector to focus additional sunlight onto it, increasing its power generation.

Why it matters: Filed before the widespread availability of low-cost, powerful microcontrollers and precise sensor arrays. These advancements now make the complex, multi-actuator tracking and light sensing system described in the claims significantly easier and cheaper to implement.
