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.

Video Friday: Strandbeest

Cars That Think

During the summer I do all kinds of experiments with the wind, sand and water. It’s the most zoomed-in, highest frame-rate observation of a Phobos solar eclipse ever taken from the Martian surface. [ Strandbeest Evolution 2021 provides an update on the evolutionary development. Every spring I go to the beach with a new beast.

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

Green Car Congress

In the future, hydrogen produced through water electrolysis is expected to be used to store energy as a way of compensating for solar or wind power’s intermittent output. In addition to being a carrier of energy, hydrogen could also be a source of energy, and its combustion would emit water (H 2 O) instead of CO 2.

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.
