A desalination membrane acts as a filter for salty water: push the water through the membrane, get clean water suitable for agriculture, energy production and even drinking. The process seems simple enough, but it contains complex intricacies that have baffled scientists for decades—until now.

Researchers from Penn State, The University of Texas at Austin, Iowa State University, Dow Chemical Company and DuPont Water Solutions published a key finding in understanding how membranes actually filter minerals from water, online today (Dec. 31) in Science. The article will be featured on the print edition’s cover, to be issued tomorrow (Jan. 1).

“Despite their use for many years, there is much we don’t know about how water filtration membranes work,” said Enrique Gomez, professor of chemical engineering and materials science and engineering at Penn State, who led the research. “We found that how you control the density distribution of the membrane itself at the nanoscale is really important for water-production performance.”

Tesla will need a landing platform to catch the rocket as it lands. According to Elon Musk its to save mass/weight and speed up the rockets readiness for its next launch.

This is for Tesla’s reusable rocket program.

SpaceX aims to develop a fully reusable Starship and Super Heavy launch vehicle, capable of performing multiple flights per day. Musk shared that not adding landing legs to the Super Heavy rocket “Saves mass & cost of legs & enables immediate repositioning of booster on to launch mount — ready to refly in under an hour,” he said. When asked if the decision to eliminate the legs is due to the high stress the vehicle would experience upon landing Musk responded, “Legs would certainly work, but best part is no part, best step is no step,” he wrote via Twitter.

For $140000, you can fly your own electric airplane. The Slovenian company Pipistrel sells the Alpha Electro, the first electric aircraft certified as airworthy by the Federal Aviation Administration (FAA) in 2018. It’s a welterweight at just 811 pounds (368 kilograms), powered by a 21 kWh battery pack—about one-fifth the power of what you’d find in a Tesla Model S. For about 90 minutes, the pilot training plane will keep you and a companion aloft without burning a drop of fossil fuel.

Those of us without a pilot license will have to wait longer for emissions-free flight—but not much. For all its challenges, 2020 has proven to be a milestone year for electric aviation. Electric aircraft set new distance records, replicated short commercial flight paths, won over the US military, and attracted buyers from big airlines.

And in June, European regulators granted another of Pipistrel’s aircraft, the Velis Electro, the world’s first electric “type certification,” deeming the entire aircraft design safe and ready for mass production (airworthiness only certifies individual aircraft).

A Swiss firm has engineered a one-third scale model of a hybrid-electric aircraft capable of vertical take-off and landing (VTOL) or efficient short take-off and landing (STOL) operations. The nifty vehicle will soon be performing its first test flight.

The firm, called Manta Aircraft, says their new model combines the best features of a helicopter and a plane.

Completing the first trip around the world exclusively on solar power, the experimental craft shows what’s possible in energy and flight.

This is some real sci-fi stuff.

Beaming solar power from outer space sounds like a Marvel movie plot, but space could remove barriers to solar acceptance that dominate the Earthbound discourse.

Volkswagen shows mobile charging robot for fully autonomous charging of electric vehicles.

A year ago, Volkswagen unveiled its mobile charging station concept in which an autonomous robot facilitates the charging of the battery of electric cars. And now, after spending a year making the concept a reality, the automaker gives us a first glimpse of the prototypes of its mobile charging robot.
