Bionavitas Devised a Way to Grow Algae Thick Within Ponds
You are at: Oilgae Blog.
Bionavitas proposes to place thin glass rods inside a pond or container and let light from the surface travel down the rod.Each rod transmits solar energy beneath the surface, allowing algae to grow at depths otherwise darkened by surface-growing organisms.
Bionavitas said it hopes to sell its light technology to other firms producing algae for biofuel.
It also plans to use the light rods itself for growing algae that can soak up heavy metals and other contaminants at old mining sites.
