Comment Re:Storage - Alpha trap (Score 1) 41

Hydrogen is a neutral atom, which made it tricky. But turns out neutral atoms, and even neutral anti-atoms, can be trapped because they have a magnetic moment, which can interact with an external magnetic field.

They are saying it does make economic sense.

From the summary: Google believes that launch costs will "fall to less than $200/kg by the mid-2030s." At that point, the "cost of launching and operating a space-based data center could become roughly comparable to the reported energy costs of an equivalent terrestrial data center on a per-kilowatt/year basis."

If that's true then space based AI farms are inevitable.

Still an order of magnitude safer. 4.6 per million miles vs .41 for waymo.

Waymo's driverless vehicles have reduced injury claims by 100 percent compared to human drivers, with an incident rate of 0.41 per million miles, which is 6.8 times lower than human drivers.

The tundra and much of the taiga – the sometimes swampy coniferous forest of high northern latitudes – were once a grassland ecosystem known as the “mammoth steppe.” It was home to abundant grazing herds of antelope, deer, caribou, horses, bison, and woolly mammoths. At the end of the Pleistocene, these herds vanished leading to an ecosystem conversion away from abundant grasses toward a more shrub-dominated community.

The tundra ecosystem that arose in the absence of these large grazing species is now affected by and contributing to human-driven climate change. Without large animals to compact and scrape away thick insulating layers of winter snow, extreme winter cold does not penetrate the soil. That fact, coupled with significantly warmer summers, accelerates the melting of the permafrost and the release of greenhouse gases that have been trapped for millennia. From a global carbon perspective, the carbon release from the melting of the world’s permafrost is equivalent to burning all the world’s forests 2 ½ times.

The work of Dr. Sergey Zimov shows promise that tundra can be converted back to grasslands with the introduction of grazers even 10,000 years after their disappearance.
