I thought algae was far more efficient than plants?

I thought algae was far more efficient than plants?
- TheAdamAndChe 10y agoIt is, but where would you get the nutrients needed to grow the algae at a scale needed to offset global climate change?
- jjawssd 10y agoHow about (farm) waste water runoff?
- ChuckMcM 10y agoThis has been suggested before. Scale is still hard. I read an article in the UC Davis algae magazine (http://www.algaeindustrymagazine.com/department/education/west/uc-davis/ http://www.algaeindustrymagazine.com/department/education/we...) a while ago that talked about flooding a fairly large acre (hectare) parcel with water, growing a layer of algae on it, then burying the algae. (process flood, algae mat grows, drain/evaporate, and plow it all under, then repeat.) The algae decomposition process releases methane (worse than CO2).

- bluGill 10y agoonly if we cannot capture methane. If we can capture it, we can run it through an engine and get the energy back. Most landfills are already doing this: it adds some extra profit to the bottom line. I have no idea if this stores any carbon anymore though.
- ramblenode 10y agoThere is research being done on iron seeding/fertilization of barren ocean waters [0]. In such places, iron is the limiting factor for algae growth. [0] https://en.wikipedia.org/wiki/Iron_fertilization https://en.wikipedia.org/wiki/Iron_fertilization
