Wow, that's tiny. I think solar modules have efficiencies up to 40% these days (47% in the lab), with 20% to 30% efficient modules being very common. But I gue

But I guess if land use isn't an issue, the algae could potentially be cheaper on a dollars per watt basis? Floating algae farms in the oceans and such.
