Here’s a really cool heliostat that can help you track sunlight.
The purpose of this cool solar device is to help you make other solar projects where you “could” make use of constant sunlight to something such as solar power grids. (or somethin’ along lines of that…)
The heliostat is the first step in his solar energy experimentations, and it is designed to keep a mirror aligned so that it keeps the reflection of the sun onto a specific point. Once the energy is focused on that point, it can be harnessed by other devices such as a solar oven. A single unit can be useful, however it gets really fun when you start adding multiple devices to concentrate a bunch of energy on a small spot.
