Broadcast power.

Very interesting technology breakthrough: the use of metamaterials to harvest microwave energy and convert it to DC (direct current), with an efficiency on par with the best solar panels.  From EurekAlert:

With additional modifications, the researchers said the power-harvesting metamaterial could potentially be built into a cell phone, allowing the phone to recharge wirelessly while not in use. This feature could, in principle, allow people living in locations without ready access to a conventional power outlet to harvest energy from a nearby cell phone tower instead.

“Our work demonstrates a simple and inexpensive approach to electromagnetic power harvesting,” said Cummer. “The beauty of the design is that the basic building blocks are self-contained and additive. One can simply assemble more blocks to increase the scavenged power.”

For example, a series of power-harvesting blocks could be assembled to capture the signal from a known set of satellites passing overhead, the researchers explained. The small amount of energy generated from these signals might power a sensor network in a remote location such as a mountaintop or desert, allowing data collection for a long-term study that takes infrequent measurements.

This is a fundamental breakthrough, and one which will have a lot of applications/implications far beyond just those mentioned above. Consider what you could do with even our current electronics technology if you didn’t need to have access to charge batteries/capacitors. Already many devices are charged through induction, though that has a relatively short-range effect, and the magnetic fields used create their own problems (and are relatively inefficient).

Combine this with RFID technology as well as nano-sized processors/memory, and you quickly get to the point where ubiquitous computing becomes not just possible but economically viable. Fascinating.

“A Look Behind the Future.”

Via Open Culture, this brilliant, and fairly hilarious, promotional documentary about the ‘forthcoming’ movie 2001: A Space Odyssey:

 

As the Open Culture post says:

The Apollo 11 moon landing would, of course, come just three years later. A Look Behind the Future reflects the enterprising if square technological optimism of that era, a tone that perhaps hasn’t aged quite as well as the haunting, bottomlessly ambiguous film it pitches.

Perzactly.

I said this in passing back in August:

Anyone who has read my blog for a while knows that these topics are ones I have discussed at some length in the past, well before the latest news. Just check the “Constitution“, “Government” or “Privacy” categories or related tags, and you’ll see what I mean.

And the things I have had to say in the past reflect a lot of what informs the background of St. Cybi’s Well.  I don’t want to give too much away, but a lot of the book is concerned with what happens when a government uses tools intended to protect its citizens to instead control them. And working off of what was already in the public domain about the different security programs, I made a lot of projections about where such things could lead.

Then came the Snowden revelations and subsequent discussion. As it turned out, I was very accurate in my understanding of the spying technology and how it could be used. Almost too much so.

 

Yeah. From the close of a long, disturbing article:

Another former insider worries less about foreign leaders’ sensitivities than the potential danger the sprawling agency poses at home. William E. Binney, a former senior N.S.A. official who has become an outspoken critic, says he has no problem with spying on foreign targets like Brazil’s president or the German chancellor, Angela Merkel. “That’s pretty much what every government does,” he said. “It’s the foundation of diplomacy.” But Mr. Binney said that without new leadership, new laws and top-to-bottom reform, the agency will represent a threat of “turnkey totalitarianism” — the capability to turn its awesome power, now directed mainly against other countries, on the American public.

“I think it’s already starting to happen,” he said. “That’s what we have to stop.”

 

Perzactly.

Back to writing. Before my predictions of dystopia all become entirely too real.

New perspective.

Via Phil Plait, had to share this:

Saturn

Saturn, obviously. But from a new perspective, as Plait explains:

But dominating this jaw-dropping scene are Saturn’s magnificent rings, seen here far more circular than usual. Cassini’s mission has been to observe Saturn and its moons, which means it tends to stay near the planet’s equator. But now scientists are playing with the orbit more, to do more interesting science. The spacecraft is swinging well out of the equatorial plane, so here we see the rings at a much steeper angle, and they are less affected by perspective.

And here’s the link to the full-size image, which is definitely worth a look.

Welcome to the paleo-future.

I grew up reading stuff like this:

R is for rocket.jpg

And even had a really cool metal rocket based on the images from Destination Moon which one of my relatives made and gave me. For the longest time those sleek rockets landing and taking off again (what NASA calls ‘Direct Ascent‘) defined what space travel meant, and I loved watching early launches which hinted at Things To Come.

Then space technology advanced, and I got a little older. Rockets were no longer cool. With all the wisdom and knowledge of a 14 year old, I dismissed the idea that anyone would want to use them for anything other than lobbing other things into orbit, and even at that they would be soon surpassed by more efficient and reusable shuttles and aerospace vehicles.

I’m glad not everyone was so easily distracted:

Welcome back to the future of my youth.

Sometimes the future is cool …

… and sometimes it is just chilling.

First, meet Seth’s grandpa:

Watson is a cognitive capability that resides in the computing cloud — just like Google and Facebook and Twitter. This new capability is designed to help people penetrate complexity so they can make better decisions and live and work more successfully. Eventually, a host of cognitive services will be delivered to people at any time and anywhere through a wide variety of handy devices. Laptops. Tablets. Smart phones. You name it.

In other words, you won’t need to be a TV producer or a giant corporation to take advantage of Watson’s capabilities. Everybody will have Watson — or a relative of the Watson technologies — at his or her fingertips.

Indeed, Watson represents the first wave in a new era of technology: the era of cognitive computing. This new generation of technology has the potential to transform business and society just as radically as today’s programmable computers did so over the past 60+ years. Cognitive systems will be capable of making sense of vast quantities of unstructured information, by learning, reasoning and interacting with people in ways that are more natural for us.

Next, consider the implications of this idea:

Now think of another way of doing this. Think of a website that is a repository of all these IDs, and is government-owned or certified. Why can’t I just visit a police station once, pay a fee (so the government doesn’t lose money on this), show all my documentation, have the government scan and upload everything so that all policemen and pertinent authorities can have access. Then my car insurance company, my health insurance company, the car registration agency can all notify this government repository if I stop paying, or if my insurance policy is not valid anymore.

Imagine a world in which the police has tablets or smartphones that show nice big pictures of you, in which whatever they currently do secretly with NSA-type agencies they do openly instead. If they find you without an ID they ask, “who are you?”, and once you give your name, they can see your photo and a ton of information about you. It would be so hard for anyone to impersonate you. I find it paradoxical that while some government agencies spy on you and know all about you, others pretend to know nothing until you show them a piece of plastic that if you lose, somebody else can impersonate you with. We need to evolve from this. We need to evolve into a system in which we have no wallets and a safer world!

Yeah, safer

TrackingPoint, the biggest name in “smart” scope technology today, is rolling out their next big project. Not too surprising, it is a military endeavor. Called the “Future of War,” TrackingPoint is gearing up for a new market.

The company has been getting a lot of attention with their high-end big-bore hunting rifles that are designed to track targets up to 1,000 yards away. The “smart” aspect of the scope technology is a host of rangefinders and sensors that, combined with optical image recognition software, calculate the ballistics of the shot and compensate for it automatically.

TrackingPoint’s hasn’t exactly concealed their intentions to develop arms for the military market. That was always a possibility and something they all but confirmed when they began talking about their second-generation precision guided rifle systems that, chambered for .50 BMG, are expected to be effective well over 3,000 yards. The cartridge, .50 BMG, is a devastating long-range anti-personnel and anti-material round.

From TrackingPoint’s website:

Target handoff can be achieved by leader touching a smart rifle icon and map location at which point the designated user will see an arrow in his scope directing him to look at handoff location. Whether from shooter to shooter, leader to shooter, drone to leader to shooter, shooter to leader to drone, handoff is a simple touch interface via a mobile device and mobile apps augmented by the appropriate a la carte communications gear.

Emphasis added, because:

The MADSS is one mean robot. Developed by defense industry leader Northrop Grumman and currently being showcased at the Fort Benning, Ga. “Robotics Rodeo,” the MADSS is a 1 1/2-ton unmanned ground vehicle designed to provide soldiers with covering fire while cutting down targets.

Make no mistake, it’s an automatic shooting machine, But it requires people to operate it and set targets. The MADSS — Mobile Armed Dismount Support System — tracks and fires on targets only once it gets the green light. It won’t shoot unless a soldier is directing it.

It’s half killer robot, half killer giant remote-control car.

But you know, not all cars need someone in control of them these days:

In Silberg’s estimation, the reason is that Audi, BMW, and Mercedes-Benz drivers are “already accustomed to high-tech bells and whistles, so adding a ‘self-driving package’ is just another option.” Throw in the possibility of a special lane on highways for autonomous vehicles and the ability to turn the system on and off at will, and premium buyers were sold on the option full-stop.

Considering that Audi, BMW, Cadillac, and Mercedes-Benz all plan to have some kind of semi-autonomous, traffic jam assistance feature either on the market or coming in the next few years, and it’s obvious that luxury brands are well aware of what their buyers want.

Draw your own conclusions.

The Source?

Got an email from an old friend and fan of Communion of Dreams which consisted of a link and this comment: Couldn’t resist…when I read this, all I could think was, “they’ve found the gel!!” 🙂

From the article at the link:

A nearby alien planet six times the size of the Earth is covered with a water-rich atmosphere that includes a strange “plasma form” of water, scientists say.

Astronomers have determined that the atmosphere of super-Earth Gliese 1214 b is likely water-rich. However, this exoplanet is no Earth twin. The high temperature and density of the planet give it an atmosphere that differs dramatically from Earth.

“As the temperature and pressure are so high, water is not in a usual form (vapor, liquid, or solid), but in an ionic or plasma form at the bottom the atmosphere — namely the interior — of Gliese 1214 b,” principle investigator Norio Narita of the National Astronomical Observatory of Japan told SPACE.com by email.

You should read the whole thing, it’s pretty cool.

And yes, there is a reason why the prequel to Communion of Dreams is based around visits to holy wells in Wales … 😉

Fearless.

At about 7:45 in this interview:

NPR: “I wonder: your original CD together Realtime is so beloved by your fans, does that make you just a tad nervous about how this much-anticipated follow-up might be received? Or do you just block that stuff out?”

O’Brien: “Ah, you know, I’m gettin’ over that.”

NPR: “But not yet? You’re still working on it?”

 

* * * * * * *

It was a hard week. He may have been only a dog, but his absence was entirely too distracting.

 

* * * * * * *

The other night I played supportive spouse and accompanied my Good Lady Wife to a professional meeting she had at the Lake of the Ozarks.

The Lake (as people in Missouri almost universally refer to it) is an interesting sort of place, from a purely anthropological perspective. Originally built to help generate electricity, it then became a tourist trap in the 1960s, then evolved into something of a Spring Break party spot for college kids throughout the state. It still has something of that reputation, though it has now branched out a bit into being a general purpose convention/resort area. I’ve written about it previously.

Anyway, like these sorts of meeting things go, the first night there was a cocktail party with an open, but limited selection, bar.  I walked up to the bar, nodded to the nice very clean cut young man behind it, asked “Got any Fat Tire? ”

“Sorry, just domestic beer. ”

I blinked, a bit stunned.

He explained further “We don’t have any of those Belgium beers.”

O’Brien:“Well, there is a sort of a fermentation that happens in people’s minds, and I guess it happened in my mind too, that you know, what, can we do that again? Can we go back to that? And then, at some point I just said ‘well, you know, if we don’t try we’ll never do anything together again'”.

Scott: “To me the word is ‘fearless’. Putting it out there, and then, with the right ingredients it’ll probably turn into something edible.”

 

Something edible, indeed. Back to work.

30 billion Earths.

How many Earth-like planets are there in our galaxy? Ones which are reasonably like ours, in terms of size, density, and location relative to their sun’s ‘habitable zone’? That’s one of the basic components of the Drake Equation, and until fairly recently all estimates were little more than speculation.

Enter Kepler:

Expanding our view from Kepler’s corner of the galaxy to show more of the Milky Way, the sky fills with billions of potentially life-bearing worlds. If we showed them all, the sky would be a mass of green. So now the green dots illustrate stars that might host such planets, visible with a good pair of binoculars on a dark night here on Earth.

From this perspective, the chances that we’re alone in the cosmos seem very slim, indeed.

The final answer? 15 – 30 billion Earth-like planets.

Of course, that doesn’t include the rest of the Drake equation values. Such as: what percentage of planets which could potentially develop life actually do so? Then what percentage of those planets develop intelligent, technologically sophisticated life? Then what percentage of such intelligent species develop interstellar communication capabilities? Then how long will such a civilization survive, out of the billions of years of history?

The last time I played with the numbers, the best guess from Phil Plait was that there were some 2.5 billion potentially habitable planets. Kepler indicates that number was too conservative, by something on the order of a factor of 10. Running the rest of the equation is largely just an experiment in gut feelings (since we don’t yet have any real data), but what is impressive is that at each stage as solid data has become available, we’ve had to adjust our “best guesstimate” numbers *upwards*. Meaning that the the total number of technologically sophisticated civilizations capable of interstellar communications out there at this point in time also goes up.

From Chapter 4 of Communion of Dreams:

“But in any event, as Arthur Bailey said this morning ‘where are they?’ Where are the aliens? That’s what’s bothering me.”

Where, indeed? I came up with my own answer, explained in Communion.

But I wonder what the real answer will be.

Limits of perception.

From the beginning of Chapter 18 of Communion of Dreams:

“But there’s something else going on. Perhaps I was being too hasty in considering this to be just a four-dimensional problem.”

“Sorry? You lost me there,” said Jon.

Gish ignored him, his attention turning in on itself. “Yes. Clearly there’s a proximity effect. Perhaps anyone who touches the artifact becomes somehow connected to the outer surface of the bubble.”

“Wait, you mean that the artifact is some kind of doorway to another dimension?”

Gish looked at Jon, annoyed. “What? Doorway? No, just that the surface of the isolation field may not conform to our simple space-time geometry.”

Not too surprising that Robert Gish was aware of this recent theory, since he’s some 39 years in our future:

A Jewel at the Heart of Quantum Physics

Physicists have discovered a jewel-like geometric object that dramatically simplifies calculations of particle interactions and challenges the notion that space and time are fundamental components of reality.

“This is completely new and very much simpler than anything that has been done before,” said Andrew Hodges, a mathematical physicist at Oxford University who has been following the work.

The revelation that particle interactions, the most basic events in nature, may be consequences of geometry significantly advances a decades-long effort to reformulate quantum field theory, the body of laws describing elementary particles and their interactions. Interactions that were previously calculated with mathematical formulas thousands of terms long can now be described by computing the volume of the corresponding jewel-like “amplituhedron,” which yields an equivalent one-term expression.

It’s an absolutely fascinating article & theory, and deserves consideration: that many of the observational problems with quantum mechanics may be due to our limited perspective from this space-time, just as our perspective from one reference point gave rise to the notion that there is something which could be considered a “universal time” — a notion which a certain Mr. Einstein dealt with.

Which, while all the math is completely beyond me, makes a certain amount of intuitive sense from the history of science. Which is: the slow progression of realization that none of our privileged positions are true. That the Sun doesn’t revolve around the Earth. That humankind isn’t different from all the other animals. That our perception of time isn’t the only one. So why should this set of spacial dimensions be the basis for reality?

Which is why I felt comfortable coming up with the “theoretical discovery” at the heart of Communion of Dreams, as discussed in this passage from Chapter 3:

Apparent Gravity was the third major application of the theories set forth in Hawking’s Conundrum, the great opus of Stephen Hawking which was not published until after his death in the earlier part of the century. He hadn’t released the work because evidently even he couldn’t really believe that it made any sense. It was, essentially, both too simple and too complex. And since he had died just shortly before the Fire-flu, with the chaos that brought, there had been a lag in his theory being fully understood and starting to be applied.

But it did account for all the established data, including much of the stuff that seemed valid but didn’t fit inside the previous paradigms. Using his theories, scientists and engineers learned that the structure of space itself could be manipulated. The first major application led to practical, safe, and efficient fusion power. Rather than forcing high-energy particles together, the forces keeping them apart were just removed. Or, more accurately, the manifestation of space between them was inverted. It took very little energy, was easy to control, but only worked in a very localized fashion.

And just for fun, here’s a little hint from my work on St. Cybi’s Well: there’s a character in there who has something of the perspective of the people working on the “amplituhedron theory” and applies it in his own way to explain the dark matter/dark energy problem. Well, it amuses me, anyway.

And I should get back to work on that.
