In fact, it might even help astronomers discover alien life on distant worlds. Source: https://earthsky.org/space/hostile-space-weather-might-not-be-all-bad-for-exoplanet-life…
G.E. Wind Turbine Prototype: 853 Feet Tall, Can Generate 13 Megawatts
Long-time Slashdot reader fahrbot-bot shares a report from the New York Times: Twirling above a strip of land at the mouth of Rotterdam’s harbor [in the Netherlands] is a wind turbine so large it is difficult to photograph.

An anonymous reader quotes a report from The Guardian: PhD in genetics might seem like an unusual requirement for the role of head chef.

Iron Powder Passes First Industrial Test As Renewable, Carbon Dioxide-Free Fuel
An anonymous reader quotes a report from IEEE Spectrum: While setting fire to an iron ingot is probably more trouble than it’s worth, fine iron powder mixed with air is highly combustible. When you burn this mixture, you’re oxidizing the iron. Whereas a carbon fuel oxidizes into CO2, an iron fuel oxidizes into Fe2O3, which is just rust. The nice thing…

Activists Turn Facial Recognition Tools Against the Police
An anonymous reader quotes a report from The New York Times: In early September, the City Council in Portland, Ore., met virtually to consider sweeping legislation outlawing the use of facial recognition technology. The bills would not only bar the police from using it to unmask protesters and individuals captured in surveillance imagery; they would also prevent companies and a variety…
Elon Musk’s Las Vegas Loop Might Only Carry a Fraction of the Passengers It Promised
The Boring Company’s Las Vegas Convention Center loop “will not be able to move anywhere near the number of people LVCC wants, and that TBC agreed to,” reports TechCrunch.
