from the recruiting-early-for-spacex dept.
HughPickens.com writes with news that Elon Musk has established "Ad Astra," a small, private school for grade-school-age kids. His goal for the school is to eliminate actual differences between the grades. The school had only 14 students for the past year, but will likely expand to 20 next September. Musk says, "It's important to teach problem solving, or teach to the problem and not the tools." As an example, he says teaching kids about tools should be more about taking an engine apart and learning about neccessary tools as the need arises, rather than just dumping information on them about a bunch of tools in an abstract way. "Musk's approach to delete grade level numbers and focus on aptitude may take the pressure off non-linear students and creates a more balanced assessment of ingenuity."

DaveS7 writes: There's been no shortage of high profile people weighing in on the subject of AI lately. We've heard warnings from Elon Musk, Bill Gates, and Stephen Hawking while Woz seems to have a more ambivalent opinion on the subject. The Epoch Times has compiled a list of academics in the field of AI research who are offering their own opinions. From the article: "A 2014 survey conducted by Vincent Müller and Nick Bostrom of 170 of the leading experts in the field found that a full 18 percent believe that if a machine super-intelligence did emerge, it would unleash an 'existential catastrophe' on humanity. A further 13 percent said that advanced AI would be a net negative for humans, and only a slight majority said it would be a net positive."

The Brainteaser Elon Musk Asks New SpaceX Engineers 490

Nerval's Lobster writes: The latest biography of Elon Musk, by technology journalist Ashlee Vance, provides an in-depth look into how the entrepreneur and tech titan built Tesla Motors and SpaceX from the ground up. For developers and engineers, getting a job at SpaceX is difficult, with a long interviewing/testing process... and for some candidates, there's a rather unique final step: an interview with Musk himself. During that interview, Musk reportedly likes to ask candidates a particular brainteaser: "You're standing on the surface of the Earth. You walk one mile south, one mile west, and one mile north. You end up exactly where you started. Where are you?" If you can answer that riddle successfully, and pass all of SpaceX's other stringent tests, you may have a shot at launching rockets into orbit.

How SpaceX and the Quest For Mars Almost Sunk Tesla Motors 126

braindrainbahrain writes: Elon Musk and his rocket company are well known to Slashdottters. This article and book excerpt tell the story of the creation of SpaceX and how it almost sank Musk's other company, Tesla Motors. Musk recalls, "I could either pick SpaceX or Tesla or split the money I had left between them. That was a tough decision. If I split the money, maybe both of them would die. If I gave the money to just one company, the probability of it surviving was greater, but then it would mean certain death for the other company." But then, at the last moment, years of work at SpaceX finally paid off: "[O]n Dec. 23, 2008, SpaceX received a wonderful shock. The company won a $1.6 billion contract for 12 NASA resupply flights to the space station. Then the Tesla deal ended up closing successfully, on Christmas Eve, hours before Tesla would have gone bankrupt. Musk had just a few hundred thousand dollars left and could not have made payroll the next day." Also, it turns out the inspiration for SpaceX was the idea of sending mice to Mars.

An anonymous reader with the news, as reported by Ars Technica, BGR, the WSJ, and more, that Tesla, in the course of the company's most recent earnings call, has announced plans to show off its much-anticipated Model 3 in March, 2016, and somewhat more tentative plans for actual availability; "late 2017" might be optimistic, but it's a start. You can listen to the whole earnings call here. Other bits gleaned from this call include a "late summer" planned delivery for the Model X SUV, and the fact that the PowerWall household battery is sold out until the middle of next year.

"Our 110,000-lbf thrust liquid hydrogen, liquid oxygen BE-3 engine worked flawlessly, powering New Shepard through Mach 3 to its planned test altitude of 307,000 feet. Guidance, navigation and control was nominal throughout max Q and all of ascent. The in-space separation of the crew capsule from the propulsion module was perfect. Any astronauts on board would have had a very nice journey into space and a smooth return." Here are the images and video.

Tesla Announces Home Battery System 514

Posted by Soulskill
from the no-plans-for-a-1.21-gigawatt-model dept.
An anonymous reader writes: Early this morning, Elon Musk finally revealed Tesla's plans for the home: battery systems designed to store up to 10 kWh of power. The company is leveraging the battery technology they've developed for their electric cars to enable more people to switch to renewable power for their homes. There will be two models of the battery. The 10 kWh version will cost $3,500, and the 7 kWh version will cost $3,000. They can deliver power at a continuous rate of 2kW, with peaks up to 3 kW. Crucially, the batteries will be warrantied for 10 years. Musk thinks the market for home batteries will expand to at least two billion, eventually. But even a much smaller uptake for now will validate the creation of Tesla's "gigafactory."

"The gigafactory is the recipient of the largest incentive package ever given by Nevada at $1.3 billion, which followed a hotly contested tax incentive bidding war between various states to land the Tesla battery plant. For the investment to pay off, Tesla needs to convince hundreds of thousands of consumers per year to buy its cars and battery products, with the gigafactory serving as a cornerstone to the company's sales strategy. ... An early gigafactory rendering released by Tesla stated that the plant will have an annual battery pack output of 50 gigawatt hours — the bulk of which will go toward batteries for cars with most of the remainder to be allocated for stationary batteries, according to figures mentioned by Tesla's chief technology JB Straubel last year. The gigafactory's sheer scope makes other battery products a possibility as well."

Okian Warrior writes: Billionaire Elon Musk will announce next week that Tesla will begin offering battery-based energy storage for residential and commercial customers. The batteries power up overnight when energy companies typically charge less for electricity, then are used during the day to power a home. In a pilot project, Tesla has already begun offering home batteries to SolarCity (SCTY) customers, a solar power company for which Musk serves as chairman. Currently 330 U.S. households are running on Tesla's batteries in California. The batteries start at about $13,000, though California's Pacific Gas and Electric Co. (PCG) offers customers a 50% rebate. The batteries are three-feet high by 2.5-feet wide, and need to be installed at least a foot and a half off the ground. They can be controlled with a Web app and a smartphone app.

Concerns of an Artificial Intelligence Pioneer 197

Posted by Soulskill
from the nobody-program-it-to-think-humans-can-be-used-as-batteries dept.
An anonymous reader writes: In January, the British-American computer scientist Stuart Russell drafted and became the first signatory of an open letter calling for researchers to look beyond the goal of merely making artificial intelligence more powerful. "We recommend expanded research aimed at ensuring that increasingly capable AI systems are robust and beneficial," the letter states. "Our AI systems must do what we want them to do." Thousands of people have since signed the letter, including leading artificial intelligence researchers at Google, Facebook, Microsoft and other industry hubs along with top computer scientists, physicists and philosophers around the world. By the end of March, about 300 research groups had applied to pursue new research into "keeping artificial intelligence beneficial" with funds contributed by the letter's 37th signatory, the inventor-entrepreneur Elon Musk.

Russell, 53, a professor of computer science and founder of the Center for Intelligent Systems at the University of California, Berkeley, has long been contemplating the power and perils of thinking machines. He is the author of more than 200 papers as well as the field's standard textbook, Artificial Intelligence: A Modern Approach (with Peter Norvig, head of research at Google). But increasingly rapid advances in artificial intelligence have given Russell's longstanding concerns heightened urgency.

Elon Musk Bailed Out of $6bn Google Takeover To Save Tesla From 2013 Bankruptcy 118

from the on-second-thought dept.
An anonymous reader sends word that Elon Musk almost sold Tesla to Google in 2013 when the company was close to bankruptcy. "Elon Musk had a deal to sell his electric car company Tesla, to Google for $6bn (£4bn) when it was heading for bankruptcy with just two weeks' worth of cash left in the bank. During the first week of March 2013, Musk spoke to his friend Larry Page, chief executive of Google, about the search giant buying his car company, which at the time was suffering from falling sales amid technical problems with the few Model S luxury sedan cars it had delivered. Ashlee Vance, author of upcoming book Elon Musk: Tesla, SpaceX and the Quest for a Fantastic Future, claims in an extra for Bloomberg two people 'with direct knowledge of the deal' said Musk and Page agreed to the buyout and shook on a price of around $6bn. This was plus promises from Google to invest $5bn for factory expansion and to not break Tesla up or close it down."

An Engineering Analysis of the Falcon 9 First Stage Landing Failure 113

Posted by Soulskill
from the ground-not-soft-enough dept.
schwit1 writes: AviationWeek has posted an analysis of SpaceX's latest attempt to land its Falcon 9 rocket on an ocean barge. Quoting: "SpaceX founder and chief technology officer Elon Musk tweeted that "excess lateral velocity caused it [the booster] to tip over post landing." In a later tweet that was subsequently withdrawn, Musk then indicated that "the issue was stiction in the biprop throttle valve, resulting in control system phase lag." In this statement, Musk was referring to "stiction" — or static friction — in the valve controlling the throttling of the engine. The friction appears to have momentarily slowed the response of the engine, causing the control system to command more of an extreme reaction from the propulsion system than was required. As a result, the control system entered a form of hysteresis, a condition in which the control response lags behind changes in the effect causing it.

Despite the failure of the latest attempt, SpaceX will be encouraged by the landing accuracy of the Falcon 9 and the bigger-picture success of its guidance, navigation and control (GNC) system in bringing the booster back to the drone ship. The GNC also worked as designed during the prior landing attempt in January, which ended in the destruction of the vehicle following a hard touchdown on the edge of the platform."
In related news, SpaceX is hoping to attempt its next landing on solid ground.

The Myth of Going Off the Power Grid 281

Posted by Soulskill
from the tell-that-to-my-hamster-wheel-colony dept.
Lasrick writes: Dawn Stover uses Elon Musk's announcement that Tesla will soon be unveiling plans for a battery that could power your home as a starting point to explore the idea that "going off the grid" is going to solve climate change. "The kind of in-house energy storage he is proposing could help make renewables a bigger part of the global supply. But headlines announcing that a Tesla battery 'could take your home off the grid' spread misconceptions about what it takes to be self-sufficient — and stop global warming." Stover worries that shifting responsibility for solutions to climate change from governments to individuals creates an 'every-man-for-himself' culture that actually works against energy solutions and does little to reduce overall greenhouse gas emissions. Instead, "smart grid" technology would be much more efficient: "With a smarter grid, excess electricity generated by solar panels and wind turbines could be distributed to a network of on-the-grid home and car batteries. Some utilities have also experimented with using home water heaters as an economical substitute for batteries."

Robots4Us: DARPA's Response To Mounting Robophobia 101

malachiorion writes DARPA knows that people are afraid of robots. Even Steve Wozniak has joined the growing chorus of household names (Musk, Hawking, Gates) who are terrified of bots and AI. And the agency's response--a video contest for kids--is equal parts silly and insightful. It's called Robots4Us, and it asks high schoolers to describe their hopes for a robot-assisted future. Five winners will be flown to the DARPA Robotics Competition Finals this June, where they'll participate in a day-after discussion with experts in the field. But this isn't quite as useless as it sounds. As DRC program manager Gill Pratt points out, it's kids who will be impacted by the major changes to come, moreso than people his age.

Steve Wozniak Now Afraid of AI Too, Just Like Elon Musk 294

quax writes Steve Wozniak maintained for a long time that true AI is relegated to the realm of science fiction. But recent advances in quantum computing have him reconsidering his stance. Just like Elon Musk, he is now worried about what this development will mean for humanity. Will this kind of fear actually engender the dangers that these titans of industry fear? Will Steve Wozniak draw the same conclusion and invest in quantum comuting to keep an eye on the development? One of the bloggers in the field thinks that would be a logical step to take. If you can't beat'em, and the quantum AI is coming, you should at least try to steer the outcome. Woz actually seems more ambivalent than afraid, though: in the interview linked, he says "I hope [AI-enabling quantum computing] does come, and we should pursue it because it is about scientific exploring." "But in the end we just may have created the species that is above us."

Musk Says Drivers May Become Obsolete, Announces Juice-Saving Upgrades 341

Posted by timothy
from the dog's-not-that-shaggy dept.
Lucas123 (935744) writes During a discussion at a Nvidia conference, Elon Musk predicted that in the future, consumers will not be allowed to drive cars because it will be considered too dangerous. [Note: compare Lyft CEO Logan Green's opposite view] 'You can't have a person driving a two-ton death machine,' he said. Others agree. Thilo Koslowski, a vice president at Gartner, said instead of laws dictating drivers must cede control to their car's computer, we may someday someday just pass signs requiring drivers to activate auto-drive functionality for certain particularly treacherous stretches of roadway. Kowlowski said fully autonomous vehicles won't be ubiquitous for another 10 to 15 years, but the government could spur that on by offering tax incentives as it does today with all-electric vehicles and hybrids. Related news: it may not be fully autonomous driving, but Tesla S drivers are promised an upgrade a few months from now that gives a taste, with the addition of automatic steering features. And though it's perhaps anti-climactic as a solution to "ending range anxiety," Musk also announced today that Teslas will get in the next two weeks a software upgrade that will greatly upgrade the cars' routing software, integrating "near-realtime" lists of available supercharger stations, and keeping drivers apprised of whether one is within range.

As reported by The Verge, the rule-makers of New Jersey have relented, and will now allow a slightly freer market for cars. Almost exactly one year after it was banned from selling its cars directly in New Jersey, Tesla will be back in business in the Garden State. Governor Chris Christie signed into law a bill this afternoon that reversed last year's ban. The new legislation comes with some limits. Tesla can only open a total of four direct sale dealerships and has to operate at least one service center. But it's a major win following a heated war of words that saw Tesla CEO Elon Musk compare local dealers to a mafia protection racket subverting the democratic process.

Elon Musk Pledges To End "Range Anxiety" For Tesla Model S 286

An anonymous reader writes: Elon Musk has used his Twitter account to announce a press conference on Thursday which he claims will end "range anxiety" for Tesla's Model S sedan. Whatever change they're making will be implemented through an over-the-air software update to the cars, affecting the entire fleet. Range anxiety is the term for a fear that your vehicle won't have enough fuel/charge to reach its destination. It's a common reason for people to avoid buying electric cars, given the much smaller infrastructure build-out compared to gas stations. If Tesla is improving the Model S's range through a software update, then it likely involves optimizations to the battery and to the ways in which power is used. Tesla has also talked about developing a feature called "torque sleep," which puts one of the drive units to sleep while not needed. They say it can wake up and begin delivering torque again "so fast that the driver can't perceive it."
