The rise of algae-powered fuel cells

Global population is constantly growing, and therefore so does energy demand. Biological solar cells were recently invented, and they use algae's photosynthesis process to convert solar light into electricity. However, charging units, which need to be exposed to direct sunlight, may often conflict with power delivery units, which must be kept cool to convert moving electrons to electricity as efficiently as possible. Researchers have recently managed to build a biophotovoltaic cell with a power density of 0.05 W/ ft2. It's true that this is only 10% of what we've come to expect from solar power cells, but algae have the unique advantage of growing and dividing naturally.
