Ocean carbon: A dent in the iron hypothesis
Oceanographers Jim Bishop and Todd Wood of the U.S. Department of Energy’s Lawrence Berkeley National Laboratory have measured the fate of carbon particles originating in plankton blooms in the Southern Ocean, using data that deep-diving Carbon Explorer floats collected around the clock for well over a year. Their study reveals that most of the carbon from lush plankton blooms never reaches the deep ocean.
The surprising discovery deals a blow to the simplest version of the Iron Hypothesis, whose ... |

How much wind is needed to power a home turbine?
First do you have what it takes? Whether you are considering a small rooftop unit or a large residential turbine you need to know how much wind power is in your area. Wind resource maps, published by the US Department of Energy show airflow speeds at 50 meters (150 feet) above the ground and are a great resource in deciding if you are in a viable location. That`s great if you are installing a larger 10 kilowatt turbine which is typically installed on a 100 foot tower and has a rotor diameter of ... |
