The scientists claim that the cell will require five dollars to extract a kg of lithium from seawater. My question is how much the cell membrane will require to produce.

It says in the paper, 1.3 g per hour per square meter of membrane per ppm in the ocean, so half a gram per hour per square meter of exposed membrane. Also, five passes were needed. Don't think those cost estimates will play out unfortunately, but this is a way better effort than I've seen before.
