whatWhat will happen if the sun is concentrated by directing sunlight to mirrors that are facing each other? i know that mirrors absorb light and dont reflect 100% but will the efficiency increase due to the multiplication of the sunlight over the multitudes of reflections? if this can be done with arrays of micro heliostats with programmable motion controllers, the reflection of the sun can be tracked and the beams within the reflections also tracked to produce an enormous amount of heat.......wont it? isntIsnt it going to be more efficient than this: https://www.youtube.com/watch?v=LMWIgwvbrcM ???http://www.youtube.com/watch?v=LMWIgwvbrcM ?
