These were the structures that would be floating at the surface made out of some inexpensive plastic material that'll allow the algae to grow, and we had built lots and lots of designs, most of which were horrible failures, and when we finally got to a design that worked, at about 30 gallons, we scaled it up to 450 gallons in San Francisco.
Мы сделали множество конструкций с разным дизайном, но большинство из них были кошмарными и неудачными. А когда мы, наконец, нашли дизайн, который подходил, мы увеличили их вместимость со 113,5 литров до 1 700 литров. Это все было в Сан-Франциско.
