Carbon emissions are one of the big concerns impacting climate change, with projects from the development of carbon dioxide-scrubbing plants to businesses pledging to offset their carbon emissions being suggested as ways to reduce our carbon footprint. Now scientists from South Korea have come up with a breakthrough concept which can turn carbon emissions into usable energy.

Scientists from the Ulsan National Institute of Science and Technology (UNIST) developed a system which can continuously produce electrical energy and hydrogen by dissolving carbon dioxide in an aqueous solution. The inspiration came from the fact that much of the carbon dioxide produced by humans is absorbed by the oceans, where it raises the level of acidity in the water. Researchers used this concept to “melt” carbon dioxide in water in order to induce an electrochemical reaction. When acidity rises, the number of protons increases, and these protons attract electrons at a high rate. This can be used to create a battery system where electricity is produced by removing carbon dioxide.

The elements of the battery system are similar to a fuel cell, and include a cathode (sodium metal), a separator (NASICON), and an anode (catalyst). In this case, the catalysts are contained in the water and are connected to the cathode through a lead wire. The reaction begins when carbon dioxide is injected into the water and begins to break down into electricity and hydrogen. Not only is the electricity generated obviously useful, but the produced hydrogen could be used to fuel vehicles as well. The current efficiency of the system is up to 50 percent of the carbon dioxide being converted, which is impressive, although the system only operates on a small scale.

In 2018, scientists announced the discovery of a extrasolar planet orbiting Barnard’s star, an M-type (red dwarf) that is just 6 light years away. Using the Radial Velocity method, the research team responsible for the discovery determined that this exoplanet (Barnard’s Star b) was at least 3.2 times as massive as Earth and experienced average surface temperatures of about −170 °C (−274 °F) – making it both a “Super-Earth” and “ice planet”.

Based on these findings, it was a foregone conclusion that Barnard b would be hostile to life as we know it. But according to new study by a team of researchers from Villanova University and the Institute of Space Studies of Catalonia (IEEC), it is possible – assuming the planet has a hot iron/nickel core and experiences enhanced geothermal activity – that this giant iceball of a planet could actually support life.

The findings were shared at the 233rd meeting of the American Astronomy Society (AAS), which took place from January 6th to 10th in Seattle, Washington. The presentation, titled “X-Ray, UV, Optical Irradiances and Age of Barnard’s Star’s New Super Earth Planet – ‘Can Life Find a Way’ on such a Cold Planet”, was delivered during a press conference on January 10th and concerned findings that appeared in a recent study.

I wonder how many people it will feed.

80 Acres Farms, an Ohio-based vertical farming startup, has raised private equity funding from Virgo Investment Group, a private equity firm from San Francisco for the construction of what it says will be the first fully automated indoor farm.

AgFudnerNews can reveal that the deal was worth more than $40 million in equity capital, according to sources close to the deal.

The funding will go towards the completion of 80 Acres’ Hamilton, Ohio facility, which was announced last year and is set to be partially operational in the next few months.

A new report reveals 42% of global coal capacity is currently unprofitable, and the United States could save $78 billion by closing coal-fired power plants in line with the Paris Climate Accord’s climate goals. This industry-disrupting trend comes down to dollars and cents, as the cost of renewable energy dips below fossil fuel generation.

Across the U.S., renewable energy is beating coal on cost: The price to build new wind and solar has fallen below the cost of running existing coal-fired power plants in Red and Blue states. For example, Colorado’s Xcel will retire 660 megawatts (MW) of coal capacity ahead of schedule in favor of renewable sources and battery storage, and reduce costs in the process. Midwestern utility MidAmerican will be the first utility to reach 100% renewable energy by 2020 without increasing customer rates, and Indiana’s NIPSCO will replace 1.8 gigawatts (GW) of coal with wind and solar.

Lazard’s annual Levelized Cost of Energy (LCOE) analysis reports solar photovoltaic (PV) and wind costs have dropped an extraordinary 88% and 69% since 2009, respectively. Meanwhile, coal and nuclear costs have increased by 9% and 23%, respectively. Even without accounting for current subsidies, renewable energy costs can be considerably lower than the marginal cost of conventional energy technologies.

Innovation in fashion is sparking radical change. In the future clothes could be computers, made with materials designed and grown in a lab.

A new wave of innovation is fueling a radical change in fashion. Wearable technology, data, automation and lab-grown materials will have a major impact on what people will be wearing in the future.

Since the birth of sewing and weaving, technology has always led developments in fashion. The Industrial Revolution mechanized manufacturing enabling mass production. In the 1960s synthetic materials like polyester took off, creating new possibilities for fashion.

Now the convergence of new technologies is opening up previously unimaginable possibilities. Self-styled fashion scientist Dr Amanda Parkes is in the vanguard of the industry’s latest reinvention. She heads up innovation at FT labs, a venture capital firm that invests primarily in disruptive fashion tech startups. Among these startups the race is on to find the next generation of renewable materials that can be grown in a lab. Traditional silk is produced from insect larvae that form cocoons, most commonly silkworms. But rather than relying on these insects bolt threads is creating silk in test tubes. Bio fabricated materials remove the need for animals and insects and they are a more sustainable and efficient way of producing raw materials.

Other companies are creating leather alternatives. Rather than using animals scientists are creating bio fabricated materials from pineapple leaves and even mushrooms. The convergence of fashion and technology also provides opportunities to transform not just clothes but the people wearing them.

Authorities in Denmark plan to build nine artificial islands off the coast of Copenhagen with a total area of more than 32 million square feet (3 million square meters.) The hope is that the new islands, which will be called “Holmene,” will become a futuristic hub for sustainable business and commerce.

“I think this could become a sort of European Silicon Valley,” said Brian Mikkelsen, the head of the Danish chamber of commerce, in an interview with The Guardian.

Homeowners tend to equate termites with property value apocalypse, but ecologically speaking, they’re more a force of stability than destruction. A new study points to how termites can help the rainforests they call home to weather droughts—which are expected to increase in frequency and intensity as climate change causes the tropics to heat up.

Termites are found across the tropics, where they feed on wood and dead leaves and build mounds that can sometimes be seen from space. Despite the wide-ranging influence of these ecological engineers, there’s been little research on how termites impact the ability of the forests they call home to withstand one of the biggest natural disturbances they face: drought.
