Hands down the cheapest way to gather the suns energy
How does this Heliostat Work
RASP: Reflector Alignment Sensor Platform
The Alignment device aka RASP is the key to this style Heliostat.
The other style of heliostat needs to know the mirror, sun and targets position in order to move the mirror.
This style of Heliostat which uses a RASP takes the sun's reflection off the mirror to align it to the target.
