British researcher proposes seeding oceans with iron filings to stimulate algae production; would absorb CO2, produce biofuels

An independent British researcher has proposed “seeding” selected areas of the world’s oceans with iron filings, to promote algae growth that would absorb carbon dioxide and be used to produce biodiesel. The researcher referred to a small-scale experiment conducted in the 1990s which had shown that the process would produce carbon-absorbing algae.
