The Laptop, Circa 1968 120

Harry writes "In 1968, computers tended to occupy entire rooms, and were therefore hard to take with you. But Computerworld reports on Anderson Jacobson's 75-pound Teletype-terminal-in-a-case, an early attempt to let folks compute from anywhere. (Well, anywhere they had power and access to a telephone for the Teletype's acoustic coupler.) Wheels were optional."

New Video of Tesla's Mass-Market Electric Car 462

Slatterz writes "The Tesla Roadster has almost mythical status among electric car enthusiasts. It's fast, with high torque over a wide RPM range, and can beat a Ferrari in terms of acceleration. Now Tesla has released new video of its upcoming new electric car, called the Model S, which Tesla Motors claims is the world's first mass produced fully-electric vehicle. Unlike the Lotus-Elise based Roadster, the Model S is a traditional sedan of the type millions of commuters might actually drive. Tesla claims it will fit seven people (if two of them are 'children under 10'), and has mounted a rather large 17in LCD in the dash. Key to Telsa's future will be the evolution of lithium-ion battery technology. Tesla Motors claiming the new Model S can travel up to 300 miles on a single charge, but the battery will still take 45 minutes to quick-recharge." (And for those in countries where it matters, this article mentions that it should also be available in right-hand drive.)

CrunchPad Will Be a 'Dead Simple Web Tablet' 145

Hugh Pickens writes "TechCrunch's Michael Arrington has been talking for a year about building a touch-screen tablet for Web surfing and now it appears that the CrunchPad is close to becoming a reality. 'We're going to make some really big announcements,' said Arrington, who predicted a prototype would be ready for unveiling by the end of July. The purpose of the CrunchPad will be very simple: surfing the Web. Turn it on and up comes a browser — 'an Internet consumption device,' for reading, checking e-mail or watching video. The CrunchPad will not have a hard drive or keyboard and photos of the latest prototype show a device with a 12 inch screen. 'The screen is now flush with the case and we've decreased the overall thickness to about 18 mm,' writes Arrington. 'The case will be aluminum, which is more expensive than plastic but is sturdier and lets us shave a little more off the overall thickness of the device.' The CrunchPad boots directly into the browser with a Linux-based operating system and a WebKit-based browser. A video of an earlier CrunchPad prototype in action shows a device which, unlike the iPhone, runs flash. 'The next time we talk about the CrunchPad publicly will be at a special press and user event in July in Silicon Valley,' writes Arrington. 'We're full on. These prototypes are real.'"

Generating Power From Ocean Buoys and Kites 131

cheezitmike writes "Researchers at Oregon State University are testing a new type of wave-energy converter to generate electricity from ocean waves: 'Even when the ocean seems calm, swells are moving water up and down sufficiently to generate electricity. ... For decades the challenge has been to build a device that can withstand monster waves and gale-force winds, not to mention corrosive saltwater, seaweed, floating debris and curious marine mammals. ... In the most recent prototypes, a thick coil of copper wire is inside the first component, which is anchored to the seafloor. The second component is a magnet attached to a float that moves up and down freely with the waves. As the magnet is heaved by the waves, its magnetic field moves along the stationary coil of copper wire. This motion induces a current in the wire — electricity.'" Meanwhile, researchers at Stanford are working to design "turbine kites" that operate at 30,000 feet, where air currents flow much faster than they do close to the ground. Ken Caldeira, a Stanford associate professor, said, "If you tapped into 1% of the power in high-altitude winds, that would be enough to continuously power all civilization."

Is the Kindle DX Worth the Money? 263

An anonymous reader writes "Now that some little time has passed, and the hype has died down a bit, I'm wondering if anyone has taken the $500 plunge and gotten a Kindle DX. From the academic-paper-reading-geek perspective, is it worth the money? How well does it work with PDFs, and is it easy to get them on and off? I haven't been able to find any good reviews on the interweb that address its usability as I would like to use it."

Squeezing a Wikipedia Snapshot Onto an 8GB iPhone 169

blackbearnh writes with this excerpt from O'Reilly Radar "Think about Wikipedia, what some consider the most complete general survey of human knowledge we have at the moment. Now imagine squeezing it down to fit comfortably on an 8GB iPhone. Sound daunting? Well, that's just what Patrick Collison's Encyclopedia iPhone application does. App Store purchasers of Collison's open source application can browse and search the full text of Wikipedia when stuck in a plane, or trapped in the middle of nowhere (or, as defined by AT&T coverage...)"

First Fully Programmable Gesture-Recognition Glove, Cheap 77

Al writes "The AcceleGlove from AnthroTronix, is the first fully programmable glove that records hand and finger movements. Other gloves — like 5DT's Data Glove, which is used primarily in virtual reality — normally cost $1,000 to $5,000, but the AcceleGlove costs just $499. The AcceleGlove comes with software that lets developers use Java to program it for any application they wish. AnthroTronix initially developed the glove with the US Department of Defense for robotic control but it could also be used in video games, sports training, or physical rehabilitation."

NASA Suggests Nano Robots To Explore Mars 104

destinyland writes "'We're going to have to do extensive robotic exploration,' says the director of NASA's Ames Research Center, suggesting nanotechnology to build self-replicating robots on Mars. Genetically engineering extraction and construction microbes could 'grow' electrical components, and eventually convert carbon dioxide on Mars into oxygen. 'If we really want to settle Mars, and we don't want to have to carry millions of tons of equipment with us to duplicate the way we live on Earth, these technologies will be key.' This interview with Peter Worden, the director of NASA's Ames Research Center, was just featured in the summer issue of H+ magazine, and he also argues that robots will be necessary to first survey Mars for underground microbes and protect the unique Martian biosphere, since it may contain clues about earth's own first life forms. In fact, given the water and carbon that's been discovered on Mars, the possibility of underground microbes is still considered real, and Worden argues that Mars 'may already be supporting life.'"

Record-Breaking Solar Cells Tailored To Location 133

Urchin writes "The quality of sunlight varies depending on where you live, but off-the-shelf solar cells are all identical. A new solar cell designed by UK firm Quantasol is easily tuned to adapt to the local light conditions, which boosts its long-term performance. Its short-term performance isn't bad though — the single junction solar cell has a peak efficiency greater than any previous device, beating a world record that's stood for 21 years."

What the US Can Learn From Europe's Pollution Credit System 425

Al writes "Technology Review discusses what a US carbon trading scheme could learn from the flawed European experience. Advocates of carbon-trading schemes like to point to Europe's cap-and-trade program as a model worthy of emulation, but the reality has been less than perfect. A glut of pollution credits, distributed without cost during both the first, transitional phase of the program and the current working phase, drove down the value of the EUAs. As a result, Europe's carbon dioxide emissions remain priced well below 20 euros per ton. With the price of pollution so low, economists say, industries that generate and consume energy have no incentives to change their habits; it is still cheaper to use fossil fuels than to switch to technologies that pollute less. Establishing a carbon price in the US system now, and tightening the system later, could send a dangerously wrong signal to financial markets looking to invest in new energy technologies."

Flapping NAV Performs Controlled Hovering Flight 128

An anonymous reader writes "AeroVironment, Inc. was awarded a Phase II contract extension in April from the Defense Advanced Research Projects Agency (DARPA) to design and build a flying prototype for the Nano Air Vehicle (NAV) program. As part of this program AV has accomplished a technical milestone never before achieved: the controlled hovering flight of an air vehicle system with two flapping wings (video) that carries its own energy source and uses only the flapping wings for propulsion and control. Two wings for propulsion and control, nothing else."

Jim Zemlin Pitches Linux App Stores For Telcos 83

angry tapir writes "Mobile carriers may start giving away netbooks for free, and Linux-based application stores could help them profit by doing so, the Linux Foundation's Jim Zemlin argued at a recent forum in Beijing. 'Selling discounted netbooks to users who buy a mobile data subscription would extend a sales strategy widely used for mobile phones. Carriers often sell phones for below retail price and let a user's subscription fees make up for the loss. AT&T already sells subsidized 3G netbooks in the US, and China Mobile has announced similar plans. Carriers worldwide are likely considering the option, which lets them charge for added services like downloads of music, videos and software, said [analyst Jack Gold]. Those downloads could come from platforms like the iPhone App Store that target mainly mobile phones today. Competition could push netbook prices down as more carriers subsidize them, which would make putting Linux on the laptops an attractive way to cut costs, said Zemlin.'"

Comcast Bringing Metropolitan WiMAX To Subscribers 71

RickRussellTX writes "Comcast plans to offer 4 megabits/sec WiMAX services to customers in Portland, Oregon starting tomorrow. Branded as 'Comcast High-Speed 2go' and '4G,' the service will require a $44.99 per month subscription in addition to existing Comcast home service. For $69.99 they will offer a dual-mode card with access to both Comcast WiMAX and Sprint's national 3G wireless network. Future rollouts are planned for Chicago, Philadelphia, and Atlanta. Say what you will about Comcast (and I know many Slashdot readers have plenty to say about Comcast), this is a daring attempt to bypass entrenched cell phone companies with a direct-to-consumer wireless service."

In Defense of the Classic Controller 251

Kotaku has an opinion piece by Leigh Alexander singing the praises of classic, button-rich controllers for the level of precision and complexity they offer. While the Wii Remote and upcoming motion-control offerings from Microsoft and Sony are generating a lot of interest, there will always be games for which more traditional input devices are better suited. Quoting: "With all this talk about new audiences — and the tech designed to serve them — it's easy to get excited. It's also easy to feel a little lost in the shuffle. For gamers who've been there since before anyone cared about making games 'for everyone,' having that object in our hands was more than a way to access the game world — it was half the appeal. Anyone who's ever pulled off a chain of combos in a console fighter can tell you about the joy of expertise and control. ... Gamers may suffer some kind of identity crisis as the familiar markers of their beloved niche evolve — or disappear entirely. The solution to that one's easy: Get over it. Like it or not, it's clear that gaming's not a 'niche' anymore, and its shape will change. The more pressing issue is whether or not controller-less gaming will truly make the medium richer. Making something 'more accessible' doesn't necessarily make it better."
