Japanese Firm Proposes Microwave-Linked Solar Plant On the Moon 330

littlesparkvt writes "Harnessing the sun's power is nothing new on Earth, but if a Japanese company has its way, it will build a solar strip across the 11,000 mile Lunar equator that could supply our world with clean and unlimited solar energy for generations." Some of the company's other projects look just as ambitious.

Intel Puts a PC Into an SD Card-Sized Casing 219

Posted by Soulskill
from the just-small-enough-to-fit-inside-your-eye dept.
New submitter mpicpp points out that Intel has unveiled a PC called Edison, which fits into a casing the size of an SD card. "Edison is based on Intel’s Quark chip, which it launched last year as its attempt to muscle in on that other flavour-of-the-month market: the so-called Internet of Things. It also reflects the company’s new-found keenness on the 'maker' community. Quark, a 22nm low-power x86 processor with two cores, sits inside Intel’s Arduino-compatible Raspberry Pi-alike Galileo board computer. Edison takes the same chip, connects it to a wee bit of LPDDR2 memory and Flash storage, and plugs in Bluetooth 4.0 Smart — aka LE — and Wi-Fi for broader connectivity."

Google Testing Banner Ads On Select Search Results 185

cagraham writes "Google promised in 2005 to never "ever" put banner ads on their search results, but that appears to be changing. The company confirmed to SearchEngineLand that it is running a "small experiment" involving large-scale banners on searches for Southwest Airlines, Virgin Atlantic, and Crate&Barrel, among others. The ads are being shown in less than 5% of searches, and only in the US, for now. Interestingly enough, the Google exec who wrote the no banner ads promise was Marissa Mayer, now CEO of Yahoo."

This Satellite Could Be Beaming Solar Power Down From Space By 2025 245

Daniel_Stuckey writes "A NASA veteran, aerospace entrepreneur, and space-based solar power (SBSP) expert, [John] Mankins designed the world's first practical orbital solar plant. It's called the Solar Power Satellite via Arbitrarily Large PHased Array, or SPS-ALPHA for short. If all goes to plan, it could be launched as early as 2025, which is sooner than it sounds when it comes to space-based solar power timelines. Scientists have been aware of the edge the "space-down" approach holds over terrestrial panels for decades. An orbiting plant would be unaffected by weather, atmospheric filtering of light, and the sun's inconvenient habit of setting every evening. SBSP also has the potential to dramatically increase the availability of renewable energy."

"Slingatron" To Hurl Payloads Into Orbit 438

cylonlover writes "People have been shooting things into space since the 1940s, but in every case this has involved using rockets. This works, but it's incredibly expensive with the cheapest launch costs hovering around $2,000 per pound. This is in part because almost every bit of the rocket is either destroyed or rendered unusable once it has put the payload into orbit. Reusable launch vehicles like the SpaceX Grasshopper offer one way to bring costs down, but another approach is to dump the rockets altogether and hurl payloads into orbit. That's what HyperV Technologies Corp. of Chantilly, Virginia is hoping to achieve with a 'mechanical hypervelocity mass accelerator' called the slingatron."

Use Tor, Get Targeted By the NSA 451

Posted by Soulskill
from the hop-online-and-disappoint-some-intelligence-agents dept.
An anonymous reader sends this news from Ars Technica: "Using online anonymity services such as Tor or sending encrypted e-mail and instant messages are grounds for U.S.-based communications to be retained by the National Security Agency, even when they're collected inadvertently, according to a secret government document published Thursday. ...The memos outline procedures NSA analysts must follow to ensure they stay within the mandate of minimizing data collected on U.S. citizens and residents. While the documents make clear that data collection and interception must cease immediately once it's determined a target is within the U.S., they still provide analysts with a fair amount of leeway. And that leeway seems to work to the disadvantage of people who take steps to protect their Internet communications from prying eyes. For instance, a person whose physical location is unknown—which more often than not is the case when someone uses anonymity software from the Tor Project—"will not be treated as a United States person, unless such person can be positively identified as such, or the nature or circumstances of the person's communications give rise to a reasonable belief that such person is a United States person," the secret document stated.'"

I agree with you about Blade Runner, but PKD did write one sort-of series: Valis, The Divine Invasion, The Transmigration of Timothy Archer (cf http://www.philipkdick.com/covers/valis_trilogy.jpg )

Certainly there is no need for a sequel here, and I expect that this will be terrible.

Ask Slashdot: Wiring Home Furniture? 235

b1tbkt writes "So it seems that furniture manufacturers have not yet acknowledged the realities of modern life. Kitchen tables could benefit greatly from built-in concealable receptacles. Even more obvious is the need for electrical wiring in couches and coffee tables. I realize that there are safety (fire) concerns but as it stands most families that I know already have power cords for laptops, tables and phones draped over, under and through their couches at any given point. If someone wanted to wire their furniture with AC or some type of standardized LV DC system, what are some dangers to watch for and what, if any, specialized hardware exists for the purpose?"

Every nonzero finite dimensional inner product space has an orthonormal basis. It makes sense, when you don't think about it.
