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.

 




TO UNDERSTAND HOW THIS STYLE  OF  HELIOSTAT  ALIGNS THE MIRROR TO THE  TARGET
LOOK AT THE SUNS SHADOW ON THE PHOTO RESISTORS
