As vital as clean water is for human life, unfortunately it’s not always easy for people to get enough. Adding insult to injury, the stuff is basically always floating around us in the air, unreachable. Now, researchers from the University of California Berkeley have developed a device that can wring drinkable amounts of water out of even the driest air.

The team says this new water harvester can produce more than 1.3 L (5.4 US cups) of water per day per kilogram (2.2 lb) of a particular water-absorbing material. This can be done even at less than 40 percent relative humidity. That’s not a whole lot of water, but it is more than enough to keep a person alive, if a situation was that dire.

The harvester was put to the test over three days in the Mojave Desert. During that time, the device produced 0.7 L (3 cups) of water per kg of material, and even on the driest day the harvester managed to wring 200 ml (6 oz) of water out of air that had an extremely low relative humidity of just seven percent.

Tesla is planning to ramp up installation of its new solar roof, but it needs to figure out a way to reduce installation time.

Now a new patent shows a possible solution by producing and installing solar roof tiles in jointed groups.

At Tesla’s 2019 shareholder’s meeting earlier this year, CEO Elon Musk said Tesla was still working on longevity testing for the new version of its solar roof tiles, Solar Roof V3, and that they are now installing the solar product in 8 states.

General Motors is the latest automaker reported to be working on solid-state lithium batteries, thanks to a $2 million grant from Uncle Sam.

The money is part of a larger grant to develop more fuel-efficient powertrains, CNET reported. The company is expected to use the rest of the money to develop a lighter-weight, more efficient engine for medium duty trucks, perhaps to replace the company’s 6.2-liter V-8.

Solid-state lithium batteries replace the flammable liquid organic solvents such as ethylene carbonate as an electrolyte in conventional lithium batteries with a solid, ceramic electrolyte that isn’t flammable. That allows engineers to cram more lithium atoms into the battery to give it more energy without increasing volatility, which could lead to lighter, batteries for electric cars with longer ranges.

A Tesla Roadster launched into space with a spacesuit-clad mannequin at the wheel has completed its first lap of the sun.

SpaceX, the aerospace company founded by Elon Musk, was blasted into orbit from Cape Canaveral last year and it is hoped that it will veer close to Mars and Earth during the course of its time among the stars.

According to tracking website Where Is Roadster?, the red sports car has now completed a solar orbit, having been cruising through the void for more than 18 months.

Not only are the batteries eco-friendly, but they are powerful as well. The researchers found a way to make them last longer and provide more electricity batteries by using silicon anodes — an electrode through which the current enters into an electrical device — instead of traditional graphite.

“Today graphite is used as the main commercial material for fabricating the anode electrodes,” Cengiz Ozkan, a professor of mechanical engineering at UC Riverside explained.

“We replaced graphite in the anodes with our new nanosilicon material derived from waste glass bottles,” he continued. “In the half-cell configuration, our batteries demonstrate performance about four times higher compared to graphite anode batteries.” Researchers at the University of California, Riverside’s Bourns College of Engineering used a three-step process to use a discarded glass bottle into lithium-ion batteries.

Homicide kills far more people than armed conflict, says new UNODC study

VIENNA/NEW YORK, 8 July (UN Information Service) – Some 464,000 people across the world were killed in homicides in 2017, surpassing by far the 89,000 killed in armed conflicts in the same period, according to the Global Study on Homicide 2019 published today by the United Nations Office on Drugs and Crime (UNODC).

“The Global Study on Homicide seeks to shed light on gender-related killings, lethal gang violence and other challenges, to support prevention and interventions to bring down homicide rates,” said UNODC Executive Director Yury Fedotov. “Countries have committed to targets under the Sustainable Development Goals to reduce all forms of violence and related death rates by 2030. This report offers important examples of effective community-based interventions that have helped to bring about improvements in areas afflicted by violence, gangs and organized crime.”

SAN ANTONIO — April 8, 2019 — A team of Southwest Research Institute and General Electric (GE) engineers have designed, built and tested the highest temperature supercritical carbon dioxide (sCO2) turbine in the world. The turbine was developed with $6.8 million of funding from the U.S. Department of Energy (DOE) Solar Energy Technologies Office (SETO), in addition to $3 million from commercial partners GE Research, Thar Energy, Electric Power Research Institute, Aramco Services Company and Navy Nuclear Laboratory. Additionally, the DOE’s Advanced Research Projects Agency — Energy (ARPA-E) Full-Spectrum Optimized Conversion and Utilization of Sunlight (FOCUS) program provided financial support and extended the test program to validate advanced thermal seals.

On humans are many, and widespread across Earth. Respiratory and cardiovascular effects of air pollution have long been recognised, and account for the majority of air pollution-related deaths. There is also a strong link between poor air quality and the incidence of lung cancer.

Globally, ambient (outdoor) air pollution causes an estimated 25 per cent of all adult deaths from heart disease, 24 per cent from stroke, 43 per cent from chronic obstructive pulmonary disease and 29 per cent from lung cancer. Household (indoor) air pollution also leads to a wide variety of similar diseases and is one of the top five causes for premature death across the world. Current estimates put the death toll from household and ambient air pollution combined at 7 million deaths a year.

Hyundai is teasing a new 1970s-inspired electric car concept set to be unveiled at the IAA Frankfurt Motor Show next month.

Over the last few years, Hyundai has been going through a bit of a transition.

They are one of the few automakers still heavily invested in hydrogen fuel cell vehicles as the alternative to fossil fuels.
