Hoppy beers do that to me. This beer was different. The water used for the brew came not from a river, a reservoir, or even a well. Instead, the water was sourced from a wastewater treatment plant located along the South Platte River. This simple fact didn’t bother me at all.

To be clear, I’m not a risk taker. Never skydived. Never paddled down Class V rapids. Never swallowed goldfish on a dare. But from what I’ve learned about purification processes for reclaimed water, drinking this limited-edition beer was eminently safe. The pilsner, blonde and translucent, like a Coors, looked and tasted like any number of beers made from water freshly obtained from creeks and rivers tumbling from Colorado’s mountain peaks. As for the strawberry-kiwi wheat beer ordered by my companion, I would have nothing of it. “That’s not beer,” I harrumphed, “that’s a fruit bowl. Undrinkable.”

I was at Declaration Brewing Co., located in Denver’s Overland neighborhood. The brewery and also a winery, InVINtions, located in Greenwood Village, were part of a regional effort. Water for the one-time specialty beverages produced by both came from the PureWater Colorado Demonstration Project. In the demonstration that was conducted in spring of 2018, water providers, engineering companies and water reuse advocates collaborated to showcase direct potable reuse treatment technologies. The water was treated using five different processes until it met federal and state drinking water standards, suitable for human consumption.

CAPE CANAVERAL, Fla. (AP) — The first astronauts launched by SpaceX are breaking new ground for style with hip spacesuits, gull-wing Teslas and a sleek rocketship — all of it white with black trim.

The color coordinating is thanks to Elon Musk, the driving force behind both SpaceX and Tesla, and a big fan of flash and science fiction.

NASA astronauts Doug Hurley and Bob Behnken like the fresh new look. They’ll catch a ride to the launch pad in a Tesla Model X electric car.

Henry Ford’s Model T was famously made partly from hemp bioplastic and powered by hemp biofuel. Now, with battery-powered vehicles starting to replace those that use combustion engines, it has been found that hemp batteries perform eight times better than lithium-ion. Is there anything that this criminally-underused plant can’t do?

The comparison has only been proven on a very small scale. (You weren’t expecting a Silicon Valley conglomerate to do something genuinely groundbreaking were you? They mainly just commercialise stuff that’s been invented or at least funded by the state.) But the results are extremely promising.

In March, Lauren McDonald was on hand for GM’s EV Day, during which much of the discussion was about the new Ultium batteries GM and LG Chem will be manufacturing at a new battery factory just down the road from the former Lordstown, Ohio assembly plant. That factory is projected to have an annual capacity of 30 gigawatt-hours of battery cells. While GM made a bunch of grandiose claims about its campaign to bring electric cars to market that day, few actual details about the Ultium battery emerged during the presentation.

As a life support engineer at NASA Ames Research Center, it’s Michael Flynn’s job to keep astronauts alive in space, making sure they have the basic necessities like clean water to survive. But launching clean water into space is cost-prohibitive, so for years, Flynn and his team have been working on new ways to recycle waste water into safe, drinking water. SmartPlanet visits Flynn’s lab and looks at how he’s doing it through a process known as “forward osmosis.”

Using Houston as a model, researchers at Rice’s Brown School of Engineering have developed a plan that could reduce the need for surface water (from rivers, reservoirs or wells) by 28% by recycling wastewater to make it drinkable once again.

While the cost of energy needed for future advanced purification systems would be significant, they say the savings realized by supplementing fresh water shipped from a distance with the “direct potable reuse” of municipal wastewater would more than make up for the expense.

And the water would be better to boot.

Good news.

In a paper published last week in Nature, though, researchers from Hong Kong University of Science and Technology devised a way to build photosensors directly into a hemispherical artificial retina. This enabled them to create a device that can mimic the wide field of view, responsiveness, and resolution of the human eye.

“The structural mimicry of Gu and colleagues’ artificial eye is certainly impressive, but what makes it truly stand out from previously reported devices is that many of its sensory capabilities compare favorably with those of its natural counterpart,” writes Hongrui Jiang, an engineer at the University of Wisconsin Madison, in a perspective in Nature.

Trying to determine how negatively charged ions squeeze through a carbon nanotube 20,000 times smaller than a human hair is no easy feat.

Not only did Lawrence Livermore National Laboratory (LLNL) scientists do that but they found that those ions are unexpectedly picky depending on the anion (a negatively charged ion). The research appears in ACS Nano.

Inner pores of carbon nanotubes combine extremely fast water transport and ion selectivity that could potentially be useful for high-performance water desalination and separation applications. Determining which anions are permeable to the nanotube pore can be critical to many separation processes, including desalination, which turns seawater into fresh water by removing the salt ions.

Mazda yesterday began production of the all-new, all-electric Mazda MX-30 at its Ujina plant No. 1 in Hiroshima, Japan. The company is keeping its first pure EV moving forward to answer the demand for electric vehicles in Europe where stricter CO₂ reductions are in place.
