Comment Re:Amazon's carbon footprint (Score 1) 100

The datacenters need the power now. From what I know of Amazon, they will upgrade to better energy sources as soon as they become available. They're putting a lot of resources into renewable energy. They're transitioning to electric trucks as fast as manufacturers can build them. Shutting down and waiting isn't an option.

California has been working on the problem for a while. If you count nuclear and hydro as renewable, the state is at about 50% renewable in terms of capacity. When demand doesn't reach capacity, the non-renewables get shut off first. The state sometimes hits 100% renewable sources. There are some big projects going on. One of the more interesting is the project to cover California aqueducts with solar panels. That will both generate a huge amount of power, and conserve a lot of water by reducing evaporation. California has a giant network of large aqueducts.

PG&E (northern california's power utility) have special electric vehicle rate plans. They make it highly advantageous to charge your cars late at night. Many EVs have options to shift charging to whatever time you'd like. Tesla, for example, supports this quite well. Owners who take advantage of this save a lot of money. This has been the situation for years. https://ancillary-proxy.atarimworker.io?url=https%3A%2F%2Fwww.pge.com%2Fen_US%2Fresi...

Some smart thermostats support off-peak timing too (eg. ecobee). And they interact with some utilities (like PG&E) to take extra measures on days with expected high demand. One strategy is to pre-chill the house/building before the peak hits, then hold back afterwards. It works quite well.

Submission + - A Mysterious Flash From a Faraway Galaxy (nytimes.com)

schwit1 writes: It was a spark in the night. A flash of X-rays from a galaxy hovering nearly invisibly on the edge of infinity.

Astronomers say they do not know what caused it.

The orbiting Chandra X-ray Observatory, was in the midst of a 75-day survey of a patch of sky known as the Chandra Deep Field-South, when it recorded the burst from a formerly quiescent spot in the cosmos.

For a few brief hours on Oct 1, 2014, the X-rays were a thousand times brighter than all the light from its home galaxy, a dwarf unremarkable speck almost 11 billion light years from here, in the constellation Fornax. Then whatever had gone bump in the night was over and the X-rays died.

The event as observed does not fit any known phenomena, according to Franz Bauer, an astronomer at Pontifical Catholic University of Chile, and lead author of a report to be published in Science.

The most likely explanation, Dr. Bauer said in the paper and in an interview, is that the X-rays are the afterglow from a gamma ray burst seen sideways. These are caused by the collapse of a massive star into a black hole or the collision of a pair of the dense stellar remnants called neutron stars, and squirt gamma rays but only in one direction. If Earth is out of the beam then all astronomers will see is an “orphan afterglow.”

Comment Pointless for TVs, great for monitors. (Score 5, Interesting) 179

I've had one curved TV, and it was very nice when my head was in the sweet spot at the center of curvature, but anywhere else, meh. Monitors are another thing: I've got one of the 34" Samsung monitors, whose curvature is set for a good reading distance, and it's an awesome experience. I now find extended periods with flat monitors to be awful.
