The calculation used actually 50 meters for light penetration as infrared light penetrates deeper, but algae still use it.

70% of the earth is covered by water. If light penetrated about 20 m, it corresponds to a volume of 4.46x10^9 km^3. In these 4 billions of cubic kilometers of water there are lots of algae, sucking CO2 and transforming them into life. Say each building makes up for 10 cubic meters of water to grow algae (10 cubic meters are 10,000 liters), we would need only about 4 x 10^15 buildings (or about 500,000 buildings for each man on the planet) to affect a 1% of CO2 absorption. Can we develop industrial and agricoltural processes that avoid polluting our waters instead?

David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
