Technology: The Most Powerful Force in the World  

Posted by Big Gav in , ,

Kevin Kelly is continuing to put out material for his forthcoming book on "The Technium" fairly regularly - the latest in stall looks at the power of technology - The Most Powerful Force in the World.

Even counting vast tracks of agriculture, the technium entails fewer than one percent of the atoms on the Earth's land surface. Yet the impact which this minute fraction of technological mass and energy has on the planet is in far disproportion to its size. Measured by impact per gram or calorie, there is nothing comparable to things we invent. Technology is the most powerful force in the world.

From the moment Sapiens emerged from Africa to colonize every inhabitable watershed on this planet, their inventions began to alter their environment. Sapien's hunting tools and techniques had far reaching affects: their technology enabled them to kill off key herbivores (mammoths, giant elk, etc.) whose extinctions altered the ecology of entire grassland biomes forever. Once dominant grazers were eliminated, their absence cascaded through the ecosystem, enabling the rise of new predators, new plant species, and all their competitors and allies, surfacing a modified ecosystem. Thus a few clans of people shifted the destiny of thousands of other species. When Sapiens gained control of fire, this technology further modified the natural terrain on a massive scale. Such a tiny trick — burning grasslands, controlling it with backfires, and summoning flames to cook grains — disrupted vast regions of the continents.

Later the repeated inventions and spread of agriculture around the planet affected not only the surface of the Earth, but its 100 km (60-mile) wide atmosphere as well. Farming disturbed the soil and increased CO2. Some climatologists believe that this early anthropogenic warming, starting 8,000 years ago, kept the next ice age at bay. Widespread adoption of farming disrupted a natural climate cycle which would have ordinarily refrozen the northern most portions of the planet by now. In other words, agriculture made (and still makes) the world safe for more agriculture. Like most complex technologies, agriculture — the integrated system of domesticated crops and animals, irrigation infrastructure and soil management — is self-sustaining and will alter its environment to further its own benefit.

Of course, once humans invented machines that ate concentrated old plants (coal) instead of fresh plants, the mechanical exhalations of CO2 furthered altered the balance of the atmosphere as the number of machines multiplied. The technium bloomed as machines harnessed this source of abundant energy. Petroleum eating machines not only transformed the ease, productivity, and spread of agriculture (accelerating an old trend), machines also drilled for more oil faster (a new trend), accelerating the rate of acceleration. Today the CO2 exhalation of all machines greatly exceeds the exhalation of all animals, and even approaches the volume generated by geological forces. Alan Weisman, writing in the World Without Us, suggest that the modern technium is the geological equivalent to a series of ceaseless volcanoes: "by tapping the [fuels of the] Carboniferous Formation and spewing it up into the sky, we've become a volcano that hasn't stopped erupting since the 1700s." And this impact is not only global, but extremely persistent: "Among the human-crafted artifacts that will last the longest after we're gone is our redesigned atmosphere." Climatologist Tyler Volk estimates that a natural geological cycle — with no technological mitigation — would take 100,000 years to return the agricultural and industrial induced CO2 atmosphere to pre-technium levels.

Each year the technium consumes more than 40 trillion pounds of coal, 1.6 trillion pounds of iron, 200 billion pounds of gypsum, and 1.2 trillion pounds of wheat, just four inputs among thousands of others needed to appease its appetite, and all those totals grow more than 5% per year. On average the technium must process twenty tons of atoms per year to support each man, women and child in the modern world.

The technium gains its immense power not from its scale but from its self-amplifying nature. One breakthrough invention, such as the alphabet, the steam pump, or electricity, can lead to further breakthrough inventions, like books, coal mines, and telephones. These advances in turn lead to other breakthrough inventions, such as libraries, power generators, and the internet. Each step adds further powers while retaining most of the virtues of the previous inventions. Someone has an idea (a spinning wheel!) which can hop to other minds, mutate into a derivative idea (place the spinning wheel beneath a sled to make it easy to haul) which disrupts the prevailing balance, causing a shift. That shift will often suggest another idea to someone else (use a cow to pull the wheeled sled), which in turn produces yet another disturbance, another rebalancing, another shift. Once started the teetering continues for many generations. As one ideas sparks two new ones and two ideas spark four, and four eight, this chain reaction of technology reverberates through the society, always gaining in accumulating energy and ceaseless movement. Efficient machines enable industry to make even more efficient machines. Smart chips assist humans in making even smarter chips. These virtuous circles are like rubbing the genie's lamp and getting three more wishes for the last wish. Magical self-amplification is a story retold in every domain of technology.

But not all changes induced by technology are magically positive. Industrial scale slavery, like that imposed upon Africa, was enabled by sailing ships which transported captives across oceans, and encouraged by the mechanical cotton gin which could cheaply process the fibers the slaves planted and harvested. Without technology, slavery at this massive scale would have been unknown. Thousands of synthetic persistent toxins have caused mass disruptions of natural cycles in both humans and other species, a huge unwanted downside from small inventions. War is a particularly serious amplifier of the great negative powers brought by technology. Horrific weapons of destruction, capable of inflicting entirely new atrocities upon society, spring directly from the most powerful force in the world.

On the other hand, the remedies and offsets to the negative consequences also stem from this most powerful force. Local ethnic slavery was practiced by most earlier civilizations, and probably in prehistoric times as well, and still continues in sporadic remote areas; it's overall diminishment globally is due to the technological tools of communication, law, and education. Technologies of detection, and substitution, can remove the routine use of synthetic toxins. The technologies of monitoring, law, treaties, policing, courts, citizen media and economic globalism can temper, dampen, and in the long run diminish the vicious cycles of war.

All change in society can be traced back to the products of our minds. The history of civilization is an ever up-cascading sequence of social organization that we invent. Societies begin as leaderless bands of hunter-gatherers, and over generational time acquire chiefs, put down roots (literally) with farms, land and water rights adjudicated by authorities, hatch cities, and eventually become states and nations. Each step in civilization is characterized by more social organization, more different kinds connections between people (beyond family relations), more webs of interdependence, producing more of what Robert Wright, author of Non Zero, calls "non-zero-sumness," that is, self-reinforcing mutual benefit. Each emergent organization in the evolution of society serves as a platform for citizens to birth yet more new ways to organize. This self-improving recursive "3-more-wishes" loop goes round and round, amplifying its original force.

The power of cooperation is not new, but this virtuous circle is more than ordinary altruism, because participants are often not consciously cooperating, and may in fact compete, or even be parasitic. A merchant in Athens selling a barrel of raisins is not cooperating with the grower of grapes in Macedonia, or the speculator in Corinth hoarding stock, but the three form a system (an emergent market) that expands all their interests. It's a win-win condition. This kind of accumulating social organization exhibits an almost mathematical flavor that transcends neighborly kindness. Rather than happy camaraderie, this increasing structure is built on information flows that tighten both trust and rivalries into a web of interdependence. As these links increase, so does the power of amplification and acceleration.

Progress, even moral progress, is ultimately a human invention. It is a product of our wills and minds, and thus a technology. We can decide slavery is not a good idea. We can decide that evenly applied laws, rather than nepotic favoritism, is a good idea. We can outlaw certain punishments with treaties. We can encourage accountability with the invention of writing. We can consciously expand our circle of empathy. These are all inventions and as much products of our minds as light bulbs and telegraphs.

The larger point is that this cyclotron of social betterment is not propelled by ethics or religion, but by technology. Society is evolved by injecting it with incremental doses of that most powerful force in the world; each rise in social organization throughout history is driven by an insertion of a new technology. ...

Name a disruption in culture today, either positive or negative, and if you press far enough back you'll find an tangible invention that sets off the imbalance. Globalism? Cheap, ubiquitous global communications. Social Security overhang? Medical advances for increasing longevity and decreasing fertility. Obesity epidemic? Cheap monoculture food system combined with passive entertainment technology. Gay rights? Emboldened by science showing gender preferences are biological. Celebrity obsessions? Broadcast media. Militant jihadism? Islam has been around 1500 years. But an imbalance between a medically enabled population explosion without a corresponding explosion in economic or political progress disrupts the former social equilibrium.

Charles Darwin and Alfred Wallace both realized from reading Malthus's work on population that natural selection is propelled by the difference between two growth patterns in the wild: population versus food. The greater propulsion of population growth could not be contained in the lesser geometric gains of its food production. This tension between the overwhelming multiplication of population and the slower expansion of its material container is the drive behind evolution.



The evolution of the technium likewise gains its unmatched power from the difference between two growth rates. The number of ideas and their transmission via computers, books, telephone lines, patents, and so on increases in an exponential fashion. Information is, in fact, the fastest growing thing on this planet. Information is especially conducive to amplification and compounding. As the number of facts increase, the connections between facts increases exponentially faster. Because the mathematical law of combinations, the number of links between pages explodes faster than the number of pages increases. New inventions in certain fields like communication, which are powered by increasing combinations of connections, can increase the speed of invention overall, revving the engines of creation. Everywhere we look, the technium is wired with self-amplifying loops ballooning up the scale of change. Fundamentally, discoveries in the science of how to discover, and inventions in how to invent (the genie process we call science) accelerate the rate of discovery and invention everywhere.

But our human ability to absorb or process this explosion of ideas increases only linearly at best. Despite years spent in education, or bathed in the best nutrition, our brains are not doubling in speed, memory, and insight every 18 months, as computers do. In fact, biologically speaking, our brains are remarkably similar to the brains of the first Sapiens 50,000 years ago. The smartest humans are not exponentially smarter than the average ones, and the average IQ of a human is only slowly increasing over time by the most minute amount (a few percent per decade in modern times). Even collectively, unaided human intelligence is only growing in tandem with the number of humans. The gap between the escalating growth of information generated by us and our machines, and our tiny marginal improvements in being able to understand the oceans of information and make meaning from it is the driver behind the rapid evolution of the technium.



The work of understanding all this information is migrating from humans to the technium. We can no longer keep up with our own creations, and so we are constructing an apparatus to structure what we think, in the same manner that we first used writing on paper to extend our memory. Now we are offloading other mental functions. The technium contains an elaborate knowledge processing system consisting of encyclopedias, classification indexes, cross references, search engines, footnotes, citations, hypertext, and the web. These technologies organize the output of our collective minds — both intangible ideas and tangible inventions — into a semantic structure, much like an ecosystem. This incredibly complicated mesh of connections, interdependencies, associations, and emergent structure gives the technium a "meaning" that is outside our of understanding.

It's reasonable to figure that since the technium is simply "that which the mind produces" then at its root the most powerful force in the world must not be technology but the human mind. If this were so we'd have to recalibrate the equation above to state that the origin of all change in our lives lays in the mysterious force of intelligence and consciousness hiding between our ears. (That assertion reminds me of a joke I heard from a friend who said "whenever I get the idea that human mind is the most powerful thing in world I just remember what it is that is telling me this.") But the claim that the human mind is foremost power is not valid. No matter how much we use our biological mind's awareness to reflect upon our mind's workings, this type of mental introspection and self-improvement leads to extremely limited improvement at best, and usually none at all. Contemplation (even in a zen position) to optimize our own mind just doesn't scale up. Unaided, the mind makes very little headway in amplifying itself.

However, the technium, which is a product of our brain, can alter the circuits that produced it. People who grow up immersed in the technologies of writing and reading think differently. I don't mean humans think differently while reading. Reading and writing are cognitive tools that, once acquired, change the way in which the brain memorizes facts and conceptualizes ideas, and these changes stimulate abstract thinking. When psychologists use neuroimaging technology, like MRI, to compare the brains of literates and illiterates working on a task, they find many differences in how their brains work whether or not they are reading. Researcher Alexandre Castro-Caldas discovered that processing between the hemispheres of the brain was different between those who could read and those who could not. A key part of the corpus callosum was thicker in literates, and "the occipital lobe processed information more slowly in individuals who learned to read as adults compared to those who learned at the usual age." Psychologists Ostrosky-Solis, Garcia and Perez tested literates and illiterates with a battery of cognitive tests while measuring their brain waves and concluded that "the acquisition of reading and writing skills has changed the brain organization of cognitive activity in general… not only in language but also in visual perception, logical reasoning, remembering strategies, and formal operational thinking." Literacy — a human invention — rewires the human mind.

It is not just writing. Music, another invention, also alters the brain in a sustainable way. Many studies have shown how listening to music strengthens the communication wiring between brain hemispheres. Beside fostering an expected growth in auditory regions of the brain, regularly playing musical instruments significantly strengthens the thickness of the corpus callosum fibers and activates the cerebral cortex. Our mind makes a drum and flute, and the drum and flute remakes our mind.


The Last Green Mile  

Posted by Big Gav in , , ,

AlwaysOn has a look at smart grids company GridPoint and their electricity management system - "Gridpoint: The Last Green Mile".

When we caught up with Gridpoint’s Vice President for Product Strategy, Brian Golden, he wanted to make sure it was clear they offer a lot more than storage. Gridpoint’s “Connect Series” product is a turnkey electricity management system that can be installed in light commercial or multi-unit residential buildings or at a utility substation, in order to monitor and manage electricity usage. And Gridpoint, who already counts among their customers virtually every major power utility in the USA, is one of a handful of companies who offer a suite of products to manage electrical resources more intelligently.

But Gridpoint’s “Connect Series” unit, about the size of a small refrigerator, is the only product currently available that not only helps electricity consumers and electric utilities manage energy more intelligently, each unit is also capable of storing up to 12 kWh of usable AC electricity. Gridpoint already has hundreds of these units in pilot installations throughout the USA.

With distributed sources of electricity now arriving in new, innovative forms, and capacity increasing exponentially, distributed storage is the final step necessary to completely transform our energy landscape. Wind power is intermittant, solar power peaks between 11 a.m. and 1 p.m. - but with distributed storage available, it doesn’t matter.

As Golden explained, there are several benefits to distributed storage. During power outages, stored electricity can be discharged back into the grid beyond the break in the line, maintaining reliable constant power. In markets where energy pricing is tiered, electricity can be stored during low off peak rates and discharged when rates are higher. Flattening the load by pushing power into the grid during peak hours of demand from distributed sources can relieve congestion on the grid. And, of course, distributed renewable energy sources such as wind and solar can be captured during their limited hours of collection, and utilized 24 hours per day from storage systems. Without distributed storage, new distributed sources of power cannot make nearly the same impact, and Gridpoint is the first company out there offering a product in the market, right now, that solves this challenge.

When I asked Golden what one of these units cost, he said they are about $10,000 to the consumer. Given the current prices of multi-family dwellings or light commercial buildings, that really doesn’t sound like very much. But as a tool to arbitrage between higher peak demand rates and lower off-peak rates, at $10,000 a pop, the unit has a fairly long payback. As a tool to flatten demand for a utility in order to prevent spot prices from spiking, however, the unit is already economical. It is also already economical for new land developments, where the storage capacity offered by Gridpoint’s products, combined with on-site sources of electricity from (for example) photovoltaics, significantly reduces the need for infrastructure to connect to the existing electrical grid - paying for itself immediately.

In any case, as Golden pointed out, we are only a few years away from batteries becoming far more economical. ...

Renewable Energy Access has an article on the need to commence construction of the smart grid - "Creating a 21st Century Grid".
In 1957, as Eisenhower began his second term as U.S. President, the first satellite launched into orbit and the first commercial nuclear reactor came online, electrical workers all over the country were installing the world's most advanced transmission and distribution (T&D) system. Today, much of that T&D system installed 50 years ago remains in place, holding together a patchwork grid for ever-expanding electricity markets.

Now in 2007 – the age of the internet, personal digital media and distributed energy — the grid has failed to keep pace with the rapidly changing technological landscape. While most industries rely on technologies that have been invented or updated in the last few years, the electricity delivery industry uses technologies that have more or less stayed the same for 100 years.

There's a common idiom that goes, “if it ain't broke don't fix it.” While the grid in the U.S. is hardly broken, it is beginning to deteriorate rapidly in some places, and it will need some serious repairs in order to meet the growing demand for electricity in general and distributed renewable electricity specifically.

“We need to see a very substantial transformation of the system,” says David Meyer, Senior Policy Advisor in the Office of Electricity Delivery and Energy Reliability at the U.S. Department of Energy (DOE). “We're outgrowing it in many parts of the nation. It's certainly not the high-capacity, integrated and smart system that we need.”

The current grid is a stiff arrangement of one-way transmission lines, centralized generation facilities and aging substations. The recent emergence of large amounts of renewable electricity in markets around the country are creating new challenges for both the transmission and distribution sectors.

On the transmission side, the issue is whether there are enough lines to bring renewable energy onto the grid. Because many of the abundant renewable resources are far away from load centers, additional lines must be built to bring wind, solar and geothermal energies to market. If plans to construct lines are not on the table, developers will be hesitant to build large projects in these rural areas.

“This is what we call the 'chicken and egg' problem,” says Meyer. “It's difficult to develop new generation without being certain that the transmission capacity is there or will be there. No one wants to be out front taking an undue portion of the risk.”

As planners look to build more of those lines, they may have some emerging technologies to consider; particularly High Voltage Direct Current (HVDC) and wires based on nanotechnology. HVDC transmission is certainly not a new concept — but it's gaining ground in the U.S. as renewable electricity will have to be transported further distances with higher efficiency in the future.

The other technology still in the research and development phase is the “armchair quantum wire,” made from tubes of carbon 100,000 times thinner than a human hair, called carbon nanotubes. When these nanotubes are made into a larger wire, they can conduct electricity far more efficiently and over far greater distances than the copper wires used today.

A leading researcher of carbon nanotubes, Dr. Wade Adams of the Richard E. Smalley Institute for Nanoscale Science and Technology, says that these nanotube wires can theoretically conduct 100 million amps of current over thousands of miles without much loss in efficiency. Today's wires conduct around 2,000 amps of current over hundreds of miles, with about 6 to 8% of the electricity lost in the form of heat.

According to Adams, these armchair quantum wires will also be one sixth the weight of current wires and so strong that they won't need support mechanisms. That means new transmission lines would be less conspicuous, and perhaps not as controversial to communities and interest groups concerned about their impact on the landscape. “That enables us to carry, say, electrical power from vast solar farms in the desert to the Northeast, or maybe from wind farms in Montana or North Dakota down to Florida – and in fact, even from continent to continent,” says Adams.

Of course, transmission lines made from carbon nanotubes are about 10-15 years away from commercialization. But if brought to scale, these new lines could transform how the nation, and indeed the world, transmits large amounts of renewable electricity. The distribution sector, which is made up of facilities that lower voltage for ordinary consumption, faces a different set of issues. One of the biggest challenges for distribution is the emergence of smaller renewable energy generators, which can sometimes cause issues with metering and load flow. This is where the “smart” grid system comes in.

In order to better control electricity entering the grid at the local level, interactive control devices, monitoring networks, energy storage facilities and demand response systems will need to be implemented. As distributed generation becomes more widespread and local communities start generating their own power, the grid must adapt in order to handle a steady two-way flow of electricity. “You have to think much more distributed than centralized, you have to solve the problem of storing energy, and it has to be much more like an internet system than the current grid is today in order to be effective,” says Adams.

These upgrades of the T&D infrastructure won't be cheap and they won't happen quickly. According to the Electric Power Research Institute, a California-based energy think tank, the cost of upgrading the grid with “smart” technologies could be $100 billion. Some analysts have put the figure at around $150 billion. While utilities and other developers would pay for much of the upgrade, ratepayers and taxpayers would also be responsible for the bill.

However, the economic impact associated with a failed grid could rival the price of an upgrade. For example, the 2003 Northeast blackout caused an estimated $6 billion in direct and indirect economic losses over only a few days. ...
