Very interesting research which could have a major positive impact in the environment, I look forward to seeing your advancements!
I have a question about the 1/4" grid mesh. Surface waters usually carry sediment and other debris along its path of movement. When the units are placed into the streams, rivers, etc. is there a concern for sediment and/or debris buildup on the mesh eventually blocking flow entirely? If the diameter of your PVC is only 2 inches I feel like the buildup could happen quickly, even a leaf could block all flow in an instant.
Also, what is the lifespan of the calcium tablets? How often will more need to be added?
Thanks so much!
