Lackner’s carbon-capture technology moves to commercialization

Read the full story from Arizona State University.

Arizona State University and Silicon Kingdom Holdings (SKH) have announced an agreement to deploy carbon-capture technology developed by Professor Klaus Lackner, director of ASU’s Center for Negative Carbon Emissions.

The proprietary technology acts like a tree that is thousands of times more efficient at removing CO2 from the air. The “mechanical trees” allow the captured gas to be sequestered or sold for re-use in a variety of applications, such as synthetic fuels, enhanced oil recovery or in food, beverage and agriculture industries.

Plant cells eat their own … membranes and oil droplets

Read the full story from DOE/Brookhaven National Laboratory.

Biochemists have discovered two ways that autophagy, or self-eating, controls the levels of oils in plant cells. The study describes how this cannibalistic-sounding process actually helps plants survive, and suggests a way to get bioenergy crops to accumulate more oil.

Inorganic perovskite absorbers for use in thin-film solar cells

Read the full story from Helmholtz-Zentrum Berlin für Materialien und Energie.

A team has succeeded in producing inorganic perovskite thin films at moderate temperatures using co-evaporation – making post-tempering at high temperatures unnecessary. The process makes it much easier to produce thin-film solar cells from this material. In comparison to metal-organic hybrid perovskites, inorganic perovskites are more thermally stable.

Record solar hydrogen production with concentrated sunlight

Read the full story from Ecole Polytechnique Fédérale de Lausanne.

Researchers have created a smart device capable of producing large amounts of clean hydrogen. By concentrating sunlight, their device uses a smaller amount of the rare, costly materials that are required to produce hydrogen, yet it still maintains a high solar-to-fuel efficiency. Their research has been taken to the next scale with a pilot facility installed on the EPFL campus.

Big Buildings Hurt the Climate. New York City Hopes to Change That.

Read the full story in the New York Times.

New York City is about to embark on an ambitious plan to fight climate change that would force thousands of large buildings, like the Empire State Building and Trump Tower, to sharply reduce their greenhouse gas emissions.

The legislation, expected to be passed by the City Council on Thursday, would set emission caps for many different types of buildings, with the goal of achieving a 40 percent overall reduction of emissions by 2030. Buildings that do not meet the caps could face steep fines.

The revival pack for tired bees

Read the full story from Planet Ark.

A British community development worker has invented a ‘survival kit’ for bees, and the prototype has shown success at reviving wearied insects.

Bees have notoriously fast metabolisms and quickly run out of energy when out retrieving pollen. In the urban environment pollinating plants can be few and far between, making the task even more difficult.

To address the issue, Norwich local Dan Harris created a credit-card style packcontaining three sachets of beekeepers’ formula sugar solution. The sugar hit can be a life-saver for an exhausted insect, and the handy pack can be kept in a wallet or pocket when out and about.

Think conservation while in the field

Illinois State Conservationist Ivan Dozier said now is the time to give Illinois NRCS a call to help solve common conservation problems, including erosion.

A closer look at Washington’s superb new 100% clean electricity bill

Read the full story from Vox.

The bill contains groundbreaking changes to the way the state’s utilities do business.

What happens to traffic when you tear down a freeway?

There’s a law of economics that says more urban highways mean more traffic. Grist looked at a real-world examples in Portland, San Francisco, and Seattle to see if that’s the case.
