"A former Google engineer who worked on the company's infamous military drone project has sounded a warning against the building of killer robots," reports Business Insider.

Long-time Slashdot reader sandbagger quotes their report: Laura Nolan had been working at Google four years when she was recruited to its collaboration with the US Department of Defense, known as Project Maven, in 2017, according to the Guardian. Project Maven was focused on using AI to enhance military drones, building AI systems which would be able to single out enemy targets and distinguish between people and objects. Google canned Project Maven after employee outrage, with thousands of employees signing a petition against the project and about a dozen quitting in protest. Google allowed the contract to lapse in March this year. Nolan herself resigned after she became "increasingly ethically concerned" about the project, she said...

Nolan fears that the next step beyond AI-enabled weapons like drones could be fully autonomous AI weapons. "What you are looking at are possible atrocities and unlawful killings even under laws of warfare, especially if hundreds or thousands of these machines are deployed," she said.... Although no country has yet come forward to say it's working on fully autonomous robot weapons, many are building more and more sophisticated AI to integrate into their militaries. The US navy has a self-piloting warship, capable of spending months at sea with no crew, and Israel boasts of having drones capable of identifying and attacking targets autonomously -- although at the moment they require a human middle-man to give the go-ahead.

Nolan is urging countries to declare an outright ban on autonomous killing robots, similar to conventions around the use of chemical weapons.

In the Bulletin of the Atomic Scientists, Slashdot reader Dan Drollette describes visiting one of North America's biggest experiments in renewable energy, off the coast of Rhode Island.

As the only commercial offshore wind farm in North America, Block Island is "setting the stage for what could be a rapid explosion in the number of commercial offshore windmills on the entire East Coast of the United States, assuming they leap the latest set of ever-changing legal hurdles set by fossil-fuel friendly regulators in Washington, DC." The goal of the Block Island test wind farm -- which started construction in the summer of 2015 and started generating some power in December 2016 -- is to see if it is technologically, environmentally, and scientifically possible to transfer offshore wind power technology from Europe to North America... This five-turbine, 30-megawatt endeavor has been effectively acting as a multi-year, real-world experiment in offshore wind power for the United States, paving the way for offshore wind farms on the northeast coast and the mid-Atlantic that could each be as much as 600 times the size of this test site, with hundreds of turbines generating electricity for hundreds of thousands of homes from just one full-scale, industrial-sized wind farm. There are more than a dozen large offshore "wind lease areas" suitable for wind farms currently up for bid from the federal Bureau of Ocean Energy Management, stretching from Massachusetts to North Carolina. Massachusetts alone is soliciting contracts for 1,600 megawatts of offshore wind development (half have now been sold), which is more than 50 times the size of this pilot project off of Block Island.... Once it is built and running, the Massachusetts project off Martha's Vineyard alone will provide enough energy to power at least 230,000 households, or about a third of the state's residential energy demand.

Other states are working on a similar gargantuan scale. All told, there are 28 offshore wind projects in the works on the East Coast, with a total capacity of 24 gigawatts, or 24,000 megawatts. To give a sense of the massive size of the generating power of the wind farms now in the works, the first commercial civilian nuclear reactor in the United States -- Massachusetts' Yankee Rowe Nuclear Power Station, now decommissioned -- generated just 185 megawatts at its peak. But after decades of false starts and tangled litigation, a sea change appears to be occurring for offshore wind in the United States, as this country races to catch up with Northern Europe, where this renewable energy source has become increasingly mainstream and increasingly cheap... And these offshore wind projects could have a big impact on the environment. The Union of Concerned Scientists estimates that the newly contracted wind farms would offset carbon emissions equivalent to removing about 270,000 cars from the road. They could play a key role in reducing the region's climate change footprint, while allowing the New England economy to grow...

Consequently, this handful of windmills in one test plot have been closely watched, studied, and debated, from multiple points of view, by many different "stakeholders," as the parlance goes -- including Wall Street analysts, investment firms, engineers, economists, sociologists, fisheries experts, environmental activists, historic preservationists, ornithologists, marine mammal biologists, Native American tribes, scallopers, long-liners, oystermen, sport fisherman, real estate investors, the tourism industry, and homeowners. And, of course, lawyers. Many, many lawyers...
The article notes that often windmill power companies "can piggyback on existing infrastructure, in the form of the high-tension power lines built for decommissioned nuclear plants or retired coal-fired plants such as the 1,500 megawatt Brayton Point Power Station on the mainland -- the last coal-burning plant in Massachusetts, which was shut down in May 2017..."

After talking to several locals, he concludes that "If there is a common thread to the comments, it is that the windmills are quiet and distant, and that with a steady and predictable source of power, islanders no longer have to worry about blackouts or brownouts... If nothing else, wind had turned out to be more reliable than ferrying barrels of diesel fuel to a generator located on an island 13 miles out to sea."

Initial results from NASA's InSight lander suggest that Mars' magnetic field wobbles in inexplicable ways at night, hinting that the red planet may host a global reservoir of liquid water deep below the surface. National Geographic reports: In addition to the odd magnetic pulsations, the lander's data show that the Martian crust is far more powerfully magnetic than scientists expected. What's more, the lander has picked up on a very peculiar electrically conductive layer, about 2.5 miles thick, deep beneath the planet's surface. It's far too early to say with any certainty, but there is a chance that this layer could represent a global reservoir of liquid water.

On Earth, groundwater is a hidden sea locked up in sand, soil, and rocks. If something similar is found on Mars, then "we shouldn't be surprised," says Jani Radebaugh, a planetary scientist at Brigham Young University who was not involved with the work. But if these results bear out, a liquid region at this scale on modern Mars has enormous implications for the potential for life, past or present. So far, none of these data have been through peer review, and details about the initial findings and interpretations will undoubtedly be tweaked over time. Still, the revelations provide a stunning showcase for InSight, a robot that has the potential to revolutionize our comprehension of Mars and other rocky worlds across the galaxy.
