The First Practical Heliostat

Rohr had originally intended his heliostat system to be used for indirect space heating and water heating. After failing to raise money to develop advanced components for those applications, however, he shifted to simpler lighting and direct heating applications. The rest will come later, he says. While the heliostat relies on sophisticated engineering and software to make it work, the end product is extremely simple in its function, he told
