All of the Eskimos met at the Copenhagen Global Warming Summit and together they asked for NASA’s 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 we’re not going to have much longer on this planet if we don’t 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 there’s 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.
France’s 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.

– 60 Minutes, the most successful American television broadcast in history, began its 52nd season in September. Offering hard-hitting investigative reports, interviews, feature segments and profiles of people in the news, the broadcast began in 1968 is still a hit in 2020. 60 Minutes makes Nielsen’s weekly Top 10 nearly every week and was the #1 weekly television broadcast three times last season.
The program still averages more than 10 million viewers, more than double the audience of its nearest network news magazine competitor. The average audience for a 60 Minutes broadcast is 150% higher than those of the network morning news programs; the audience dwarfs the number of viewers drawn by the most popular cable news programs.

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 —one of the constituents of Earth’s mantle—at 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.
“Because 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,” said Federica Coppari, LLNL physicist and lead author on the study. “With 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.”
Whether toting the neighborhood kids home after soccer practice or loading up for a road trip, SUVs offer the ultimate in vehicle utility. If you’re in the market for an electric SUV though, the options are both few and pricey. Unless of course you head on over to the coolest little corner of the web, the electric vehicle market on Alibaba.
