A new company called Otto is planning to build self-driving systems for long haul trucks. The company is founded by a highly professional experts including former members of Google’s car team.
As we all know, every year thousands of people die in truck accidents, so the company has a very tough challenge of producing a safer self-driving truck than the human driven ones. Otto started out with tools to help truck drivers perform their job with increased safety, but now it is working on technology that, in time, can automate parts of the drive on highways.
The company said it has already completed one public highway demo of its system, and it is hatching grander plans beyond that.
The founders noted that manufacturers’ systems would require all-new trucks, unlike Otto, which could be retrofitted.
“If you need to replace all of your trucks to get the technology on it, the rate of penetration you’ll be able to have is pretty low. Trucks last ten years, a million miles.”
Elon Musk’s space company has asked the federal government for permission to begin testing on an ambitious project to beam Internet service from space, a significant step forward for an initiative that could create another major competitor to Comcast, AT&T and other telecom companies.
The plan calls for launching a constellation of 4,000 small and cheap satellites that would beam high-speed Internet signals to all parts of the globe, including its most remote regions. Musk has said the effort “would be like rebuilding the Internet in space.”
If successful, the attempt could transform SpaceX, based in Hawthorne, Calif., from a pure rocket company into a massive high-speed-Internet provider that would take on major companies in the developed world but also make first-time customers out of the billions of people who are currently not online.
The idea of saturating Earth with Internet signals from space has long been the dream of prominent business tycoons, including Bill Gates in the 1990s. But many of these ventures have run into obstacles that Musk is working to avoid. Musk has his own rocket, and he has said his swarm of satellites will be more efficient and inexpensive than relying on a handful of big devices that are difficult to replace.
Dish Network and DirecTV, for instance, have for years relied on a few older satellites that are cast much farther into space and can serve only specific regions such as the United States. SpaceX’s web of satellites would wrap around Earth in low orbit, handing off Internet signals to one another to make connections more reliable and to reach more areas.
The filing, made with the Federal Communications Commission late last month, is the first public glimpse into how Musk will move ahead with the project.
Musk isn’t the only billionaire entrepreneur who is pursuing such an idea. Virgin’s Richard Branson has partnered with a company with similar ambitions. Both ventures would have to succeed where many have failed.
Facebook recently abandoned its plan to build a $500 million satellite that would provide Internet service across the globe, according to the Information, a tech site.
And a previous effort by a firm called LightSquared to use satellites to provide wireless service fell apart three years ago, despite initial backing from the FCC. Military officials complained at the time that the technology interfered with the radar used by planes — a problem that shouldn’t hinder Musk’s effort, industry officials said.
Musk’s FCC filing proposes tests starting next year. If all goes well, the service could be up and running in about five years.
The satellites would be deployed from one of SpaceX’s rockets, the Falcon 9. Once in orbit, the satellites would connect to ground stations at three West Coast facilities. The purpose of the tests is to see whether the antenna technology used on the satellites will be able to deliver high-speed Internet to the ground without hiccups.
Despite a history of failed satellite ventures, wealthy individuals and companies are pouring fresh funds into exploring satellite-based communications. Google and Fidelity recently invested $1 billion into SpaceX, in part to support the satellite broadband Internet project.
A company called OneWeb, backed by Virgin’s Branson and founded by Greg Wyler, has similar ambitions: “OneWeb’s mission is to bring the entire world online to improve quality of life and spur economic and national development where it’s needed most,” Wyler has said.
Wyler was also involved in launching O3b Networks, which already has 12 satellites in space, providing Internet to 40 customers, including Royal Caribbean International, the Republic of Congo and the Papua New Guinea University of Technology, an O3b spokeswoman said.
Some analysts say that while the technology appears promising, the basic logistics are difficult to overcome. In the mid-1990s, Teledesic, a company funded by Gates, legendary wireless executive Craig McCaw and a Saudi prince, tried to employ a similar plan to use low-Earth-orbiting satellites to provide Internet access. But costs ballooned to more than $9 billion, and the venture ultimately collapsed.
The new space entrepreneurs are proposing technology that is smaller, built in-house and therefore cheaper to operate, industry officials say.
“Some people might say the idea of satellite broadband has come and gone. But the cost structure of the business is so much better than when Bill Gates tried it,” said Paul Gallant, analyst at Guggenheim Partners, an investment firm. “I think Musk’s track record of disruptive innovation would make this a really attractive business for the . . . FCC to support.”
SpaceX declined to comment for this article beyond the public document of its plans. The FCC declined to comment, saying the application is under review.
In January, at a private event to recruit engineers to work at a new satellite design and manufacturing plant in Redmond, Wash., Musk predicted that SpaceX’s system would reach remote regions and handle up to 10 percent of Internet traffic in urban and suburban regions, “where people are stuck with TimeWarner or Comcast.” His remarks were videotaped by someone in the audience and posted on YouTube.
It would also be a “real enabler for people in poorer regions of the world,” Musk said, though he later conceded that SpaceX would need permission from countries to operate the service, a process that could be difficult, if not impossible.
In recent years, SpaceX has moved from a spunky start-up with a seemingly outlandish goal of colonizing Mars to disruptive competitor that has remade the rocket launch business. It became the first commercial space company to fly supplies to the International Space Station. Last year, it won a separate contract to fly astronauts there by 2017. And the Pentagon recently qualified the company to compete for lucrative missions to launch national security satellites into orbit.
SpaceX’s main goal remains flying people to Mars, because in order to survive, Musk thinks, humans must become a “multi-planetary species.”
“Mars is going to need a global communications system, too,” he said in his January remarks. “A lot of what we do developing Earth-based communications can be leveraged for Mars, as well, as crazy as that may sound.”
US scientists hail breakthrough in technology they say could provide safer, more convenient, greener alternative for laptops and mobiles.
Scientists say they have invented a new battery that could fully charge a smartphone in just one minute.
The researchers have created an aluminum battery which they hope could replace the lithium models commonly found in laptops and mobile phones.
And as well as the “unprecedented charging times” of their aluminum prototype, the team said it was also safer than lithium-ion batteries as it was less prone to catching fire and more environmentally friendly than alkaline models such as AA and AAA.
Publishing the findings in the journal Nature, Hongjie Dai, a professor of chemistry at Stanford University, hailed it as a breakthrough in battery technology that went further than previous attempts using aluminum.
He said: “We have developed a rechargeable aluminum battery that may replace existing storage devices, such as alkaline batteries, which are bad for the environment, and lithium-ion batteries, which occasionally burst into flames. Our new battery won’t catch fire, even if you drill through it.
“Millions of consumers use 1.5-volt AA and AAA batteries. Our rechargeable aluminum battery generates about two volts of electricity. That’s higher than anyone has achieved with aluminum.”
The prototype was said to be more durable, withstanding more than 7,500 cycles without any loss of capacity and surpassing previous aluminium batteries which died after just 100 charge-discharge cycles, while a typical lithium-ion battery lasts about 1,000 cycles.
“This was the first time an ultra-fast aluminium-ion battery was constructed with stability over thousands of cycles,” the report’s authors wrote.
Dai added that lithium batteries could “go off in an unpredictable manner” and cited a ban by US airlines Delta and United on bulk shipments on passenger planes.
And the new design could be used to store renewable energy of the electrical grid, the researchers suggested.
Meanwhile, co-author Ming Gong said: “Another feature of the aluminium battery is flexibility. You can bend it and fold it, so it has the potential for use in flexible electronic devices. Aluminium is also a cheaper metal than lithium.”
A team of scientists based in Korea and Canada who transplanted human neural stem cells (hNSCs) into the brains of nonhuman primates (NHPs) report that the hNSCs had differentiated into neurons at 24 months and did not cause tumors. The study is scheduled to be published in Cell Transplantation. (more…)
