Astronauts would have to fly their rocket into the Spaceline, attach to a solar-powered shuttle and be dragged up to the Moon.

Carbon nanotubes will need to be built on a large scale for the design.

Zephyr Penoyre, one of the Columbia astronomy graduate students behind the Spaceline, told Futurism: The line becomes a piece of infrastructure, much like an early railroad.

As part of continuing efforts to ensure their vehicles are the safest cars on the road, Tesla’s “Bug Bounty” program gives awards to security researchers that uncover vulnerabilities in the company’s various product systems. Perhaps one of the most impressive parts of that program, however, is Tesla’s ability to remedy the flaws quickly. In the most recent example of their dedication to security, a Bug Bounty find from April this year is now being patched via an over-the-air (OTA) update in 2019.32.

Last year, a Tesla Model S key fob was hacked by a team led by Lennert Wouters of Katholieke Universiteit Leuven in Belgium (KU Leuven). The security flaw enabled would-be car thieves to clone a fob in less than two seconds, after which the vehicle could be driven off. Tesla subsequently offered a multi-part fix: PIN to Drive, a software update, and a new fob. Wouters again found a very similar flaw in the new fob, but this time the fix only required an OTA update which patched both the vehicle software and the fob’s configuration via radio waves.

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.

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.

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.

Who knew?

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.

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.”
