Reserch Institute for Photobiological Hydrogen Production   -A Grand design for large-scale renewable energy production-

We are proposing inexpensive bioreactor

Image of bioreactor on sea surface

Bioreactor: 3-layerd plastic bags 25m width and 200m length
Bioreactor consist of 3-layerd plastic bags.

example of a large bioreactor

Membranes: 0.08 mm thick, 480 cm3/m2 bioreactor surface, $0.48-0.96 /m2 (recycled plastic: $1-2/kg, virgin plastic: $2-4/kg)

Bioreactor consist of 3-layerd plastic bags. It's spread over sea surface.
Fresh-water based medium will spread over sea surface
Fresh-water cyanobacteria (GM) if escaped, will not survive.
