Start-up Climos, which wants to experiment with large plankton blooms to mitigate climate change, gets $3.5 million from Braemar Energy Ventures.
Is fertilizing the ocean with iron to grow plankton a viable way to fight global warming? Climos, and its backers, want to find out.
Climos looks for more funding; solar power for Fenway Park; more green building materials for Serious Materials; and "burpless" grass to reduce cows' methane emissions.
A geo-engineering technology called ocean seeding is gaining interest from green tech entrepreneurs but criticism from some environmental groups.
Trying to mimic the cooling effects of volcanic eruptions by injecting sulfur into the atmosphere would badly damage the ozone layer, an NCAR study concludes.
Researchers find that seeding ocean with iron to feed plankton and sequester carbon has flaws, while debate continues over land use affects carbon emissions from ethanol.
Plastic pollution in the Pacific Ocean is only getting worse and there's no clean tech solution, according to oceanographer Charles Moore.
Oil giant Total invests $45 million plastic solar cell company Konarka, while DARPA funds a project to make jet fuel from algae for military planes.
