Pilot Project Sends Kelp–and Carbon–to the Seafloor

Cars That Think

Last January, in the waters off Cebu City in the Philippines, researchers first deployed a huge flexible ring seeded with seaweed and spanned by spokelike ropes and tubes. Every nightfall, cranks mounted on a floating platform lower the ring 25 meters below the surface to expose the seaweed to cooler, more nutrient-rich water.

Study: Atmospheric Engineering with Aerosols Could Reduce Effectiveness of Certain Kinds of Solar Power

Green Car Congress

The atmospheric engineering scheme of using sunlight-scattering stratospheric aerosols to combat global warming could reduce the effectiveness of certain kinds of solar power generation systems using parabolic or other concentrating optics.

Test of Planet-Cooling Scheme Could Start in 2022

Cars That Think

The proposal calls for what’s known as “solar geoengineering”: cooling the planet by deflecting sunlight that would otherwise strike the planet. Little is known about how, or whether, solar geoengineering might work and how the particles would react and move in the stratosphere. Concentrations of greenhouse gases are at.

France’s IFPEN studying industrial potential of onshore sources of natural hydrogen

Green Car Congress

IFP Energies nouvelles (IFPEN) has become one of the first global research centers actively to investigate onshore natural hydrogen emissions after the discovery of offshore sources of the gas in the 1970s. In this environment, volcanic systems create hydrothermal circulation, bringing together sea water and peridotites at high temperatures.
