Submission + - Tesla Claims Its New $3,000 Battery Will Let Homes Go Off Grid (computerworld.com)

Lucas123 writes: Tesla CEO Elon Musk last night announced a new business line and three new lithium-ion batteries it will sell for residential and commercial use. The wall-hung residential battery — called the Powerwall — has a starting price of $3,000 and holds 7kWh of capacity. A 10kWh model retails for $3,500. The batteries can be ordered today and will be shipping in three to four months. The stylized home batteries come in different colors and protrude just 7.5-in a wall. Up to nine Powerwall battery units can be daisy-chained together on a wall to provide homes with up to 90kWh of power. The new commercial-grade battery, called the Powerpack, is a monolithic tower that will sell in 100kWh modules for $25,000. Musk said the Powerpack can scale infinitely, even powering small cities. The new batteries are being sold to supplement intermittent power like solar and wind, but Musk said the technology, which will be open sourced for other companies to use, can take homes and businesses of the grid. The average U.S. household uses about 20 kWh to 25 kWh of power every day, according to GTM Research." You can take your solar panels, charge the battery packs and that's all you use," said Musk, who is also chairman of SolarCity, the largest installer of solar panels in the U.S. Residential households and companies with a solar power systems can charge the batteries during the day and use them in off peak hours or supplement power use during peak hours to avoid time-of-use tariffs imposed by utilities. Tesla is already manufacturing the batteries in its current facilities, but it will soon turn that operation over to its Gigafactories, the first of which is under construction outside Reno, Nevada and will go online next year. Like the batteries, the Gigafactory process will also be open for other companies to emulate in the hope that renewable power combined with battery storage will someday eliminate the need for fossil fuel production of energy. "This is not something we think Tesla will do alone," Musk said. "There's going to need to be many other companies building Gigafactory-class operations of their own. We hope they do."

Just make the H1B slot an expiring license (say 5 years). Auction it off at the beginning and allow it to be resold on the open market until it expires. Then you can stop bothering with questions about pay gaps and other nonsense. If there's a $10K per year arbitrage opportunity, the market will quickly sort it out.

We could use the spot price of visas at different maturities as a "yield curve" to see what the predictions are for future technical labor demand and as an indicator for how tight labor demand is right now. Best of all, the visas will be used on rock stars who are actually worth importing rather than being doled out more or less at random.

H1B fees and legal expenses are not cheap, nor is paying international relocation expenses for a candidate and his/her family, so we're certainly not saving money by hiring H1B's.

You just described the alternative of paying enough to make your total package competitive as being too expensive. It sounds like you're saving money by that any reasonable definition, even after the government and lawyers take their share. If it wasn't cheaper than raising your pay rates, you wouldn't be doing it.

That being said, I'm willing to grant that a company that hires PhD level people is much more likely to run into a real hard limit when it comes to finding subject matter experts, and they're the types of operations that the H1B system is supposed to work for on paper. If we did the sensible thing and auctioned off H1B slots and allowed them to be resold on an open market, those are probably the types of companies that would buy them.

Submission + - LG G4 And Qualcomm's Snapdragon 808 Benchmarked (hothardware.com)

MojoKid writes: LG officially lifted the veil on its new G4 flagship Android phone this week and the buzz has been fairly strong. LG's display prowess is well known, along with their ability to pack a ton of screen real estate into a smaller frame with very little bezel, as they did with the previous generation G3. However, what's under the hood of the new LG G4 is probably just as interesting as the build quality and display, for some. On board the LG G4 is a Qualcomm Snapdragon 808, the six-core little brother of the powerful and power-hungry Snapdragon 810 that's found in HTC's One M9. The One M9 is currently one of the fastest Android handsets out there, but its battery life suffers as a result. So with a six-core Snapdragon and a slightly tamer Adreno 418 graphics engine on board, but also with 3GB of RAM, it's interesting to see where the G4 lands performance-wise. It's basically somewhere between the HTC One M9 (Snapdragon 810) and the Snapdragon 805 in the Nexus 6 in CPU bound workloads, besting even the iPhone 6, but much more middle of the pack in terms of graphics and gaming.

That always gets me. At 17, you're old enough to enlist in the military, be issued deadly weapons and get shipped over seas to enforce U.S. foreign policy, which may involve killing lots and lots of people.
