Plant based plastics. đ
German chemists have developed two sustainable plastic alternatives to high-density polyethylene that can be chemically recycled more easily and nearly 10 times as efficiently, thanks to âbreak pointsâ engineered into their molecular structures.
Using state-of-the-art plasma technology to make cheap fertilizer for small farmers may sound like magic, but it has now become reality. Researchers at Eindhoven University of Technology (TU/e) have built a small plasma-powered plant that produces nitrogen-based liquid fertilizer only using sun, water and air. âThe plant is easy to set up, sustainable and very efficient,â says TU/e researcher Fausto Gallucci, who together with partners in Africa, Germany and Portugal has done successful tests of the device in Uganda. âWe now want to bring the mini-plant to the market, so that it becomes available to farmers around the world.â
No fuel. No electricity. Just the power of nature! This pump harnesses the flow of rivers to bring water to farmers over a mile away! Itâs an affordable and sust⊠See More.

All of the Eskimos met at the Copenhagen Global Warming Summit and together they asked for NASAâs focus. In the end, they managed to get the publicity they wanted, and with it, they carried out a deadly premonition. They claimed that the atmospheric patterns of the earth are increasingly shifting, being changed by emissions to the extent where weâre not going to have much longer on this planet if we donât change our way. The Sun is no longer rising from where it is meant to or so they say, and they state that the day no longer seems usual.
Rice University engineers have suggested a colorful solution to next-generation energy collection: Luminescent solar concentrators (LSCs) in your windows.

Right now, the entire electric VTOL scene is a house built on a foundation of faith. Faith that the hordes of researchers beavering away on next-gen battery technology will achieve an enormous energy density breakthrough, or faith that hydrogen fuel cell powertrains will prove safe, reliable and practical in an aviation context.
Both seem likely, eventually, but the urban air taxi industry is pushing to be up and running within five years, and right now thereâs no powertrain on the market that can keep these energy-intensive vertical-lift birds in the air long enough to be practical in a commercial sense.
Franceâs Ascendance sees an opportunity for an intermediate step. The company was founded by four ex-Airbus employees who worked on the groundbreaking E-Fan project, which back in 2015 became the first electric aircraft to cross the English Channel. Now, the team is working on a hybrid initiative to make long-range, low-emissions VTOL flight a reality even before the battery and hydrogen guys make their breakthroughs.
Changing literally everything to get emissions to zero.

So you like a leather wallet? Check out this sustainable alternative made from banana tree waste! After banana trees are harvested, theyâre chopped down to make way for younger fruiting trees, and their waste can become SO MUCH STUFF! Cruelty-free and super cool, whatâs not to love?
Advances in astronomical observations have resulted in the discovery of an extraordinary number of extrasolar planets, some of which are believed to have a rocky composition similar to Earth. Learning more about their interior structure could provide important clues about their potential habitability.
Led by Lawrence Livermore National Laboratory (LLNL), a team of researchers aims to unlock some of these secrets by understanding the properties of iron oxide âone of the constituents of Earthâs mantleâat the extreme pressures and temperatures that are likely found in the interiors of these large rocky extrasolar planets. The results of their experiments were published today in Nature Geoscience.
âBecause of the limited amount of data available, the majority of interior structure models for rocky exoplanets assume a scaled-up version of the Earth, consisting of an iron core, surrounded by a mantle dominated by silicates and oxides. However, this approach largely neglects the different properties the constituent materials may have at pressures exceeding those existing inside the Earth,â said Federica Coppari, LLNL physicist and lead author on the study. âWith the ever-increasing number of confirmed exoplanets, including those believed to be rocky in nature, it is critical to gain a better understanding of how their planetary building blocks behave deep inside such bodies.â
