Preparing for the Future

Sailing into the future...

How stunningly weird is it, that we’ve been in space for almost 60 years… and our first real-genuine experiment deploying a solar sail is about to be launched (by the Planetary Society), later this month? A human lifespan… to get around to trying something to simple, obvious and inexpensive?   The delay is so strange and unlikely, it almost makes one conjure up sci-fi/thriller/paranoid explanations. 

Support the solar sail on Kickstarter.  Something worthwhile.

Other interesting things, in the offing...

Innovating for the future: an interesting article about the history of and the death… and rebirth(?) of corporate research labs, reports that "innovation may no longer be in corporate-affiliated research parks, but is cropping up in unexpected places... which goes hand in hand with rapid shifts and expansions in the information landscape." 

Ah, but as you'll hear me repeat, those who have sabotaged investment in U.S. research are traitors and enemies of our children.  No less.

Financing the future...will we see...an attack of the algorithms? In a disturbing trend, monetary funds run by robots now account for $400 billion of the worldwide economy.

Mining for the future...Last summer the UN's International Seabed Authority issued the first deep sea exploration permits, allowing companies to start actively looking for places to mine Manganese nodules and other sources of rare earth elements from the ocean floor. As I forecast in EARTH (1989). Might this be a way around the current Chinese near-monopoly on rare earths production?

In the short term. Maybe.  But till we're mining asteroids (including "davidbrin") we won't yet be rich enough.

== Powering the Future ==

Speaking of solar... Bike lanes covered with solar panels follow the median of highways in South Korea: “...for 20 miles between the cities of Daejeon and Sejong, they can be running down the median of a six-lane highway. And what's really special about this one is that it is covered with solar panels, generating electricity and shading the cyclists as they ride,” reports this article in TreeHugger. Sounds nice -- till you factor in noise, danger and exhaust fumes.  Reboot idea source.  Try again.

My own passion is to see solar panels running along the west’s great aqueducts, shading the water and reducing evaporative losses. The energy that’s generated would benefit from a clear right-of-way for cheap power lines.  Add a bike-path? Sure!

Better yet, the aqueducts are (not-quite but sort-of) perfect for Elon Musk’s Hyperloop transport system! The main California Aqueduct runs roughly along the I-5 interstate freeway – with, admittedly, a few more twists. The point is that Elon might be able to flexibly hop from one to the other, with the aqueduct portions being much, much cheaper to acquire and build upon than portions running down an interstate median. Now, to power with that water-and-electricity-saving roof of solar cells.

Been musing this idea more and more…

One of you did some of the math: “Just the California aqueduct is 1129 km long and 10 meters wide.  That figures to a surface area = 1.129E7 m^2.  Now, assuming solar energy 1.2 KW per M^2, with 20% conversion efficiency: then this surface area would generate 0.27E7 KW… or 2.7 GigaWatts. Out of California’s current electrical demand ~50GW, that’d be a whopping 6%. Compare this to existing California solar = 6GW, so a complete solar roof over the CA Aqueduct (and that is only the largest of California’s many water channels) would provide half again the existing solar power base in California alone.”

It's been done in India: a canal in Gujarat topped with solar panels. See the picture to the right.

Hm, well, the numbers can be quibbled in either direction.  But not by enough to refute the notion. Now factor in all benefits:

1) No appreciable environmental tradeoffs. Very little additional land need be set aside for this power plant, unlike the vast solar arrays now being erected in sensitive desert areas.

2) Access is simple and secure. The roads and infrastructure needed for construction are already in place.  Indeed, the accompanying power lines can simply follow existing aqueduct rights-of-way, saving time and expense.

3) Excess power has an immediate use, pumping water over the Tehachapis to holding reservoirs that can then be swiftly tapped for hydro power, when clouds come in.

4) Prevention of evaporative loss from the aqueducts themselves.  This is, of course, the biggest win-win benefit, in times of drought. And this is where a call to the smart mob comes in.  Can anyone find estimates of what this saving would amount to?  

Indeed, one must wonder about unintended consequences, as some evaporation would then condense on the solar roof’s support structures. Anti-corrosion will have to be part of basic planning.  Still, here's the capstone that makes all of this sound plausible --

Elon Musk tweeted, "Have asked SolarCity if we can do something philanthropic with the CA aqueducts to help the water crisis. Investigating…"

And...what about the All American Canal as well?

== Preparing for worst cast scenarios ==

Battling infectious diseases: There have been missteps. As this article notes, empty Ebola clinics have been reported: “After spending hundreds of millions of dollars and deploying nearly 3,000 troops to create Ebola remedy centers, the United States ended up creating facilities that have largely sat empty: Only 28 Ebola sufferers have been treated at the 11 remedy units built by the United States military…”

Before getting all outraged at this “waste,” perhaps some perspective? All right, the help arrived a bit late and our civil servants learned a lot, so that they’ll do better next time. Which is… um… kinda the point, yes? For all of its tragedy, this Ebola outbreak was on the medium-small scale, compared with the nightmare scenarios we all might face, next year or next decade.

On that broader perspective, this exercise was, in fact, worth every penny! We’ll be quicker off the mark, next time, better skilled and equipped.

 == Educating for the Future ==

Along the same lines as my posting -- How the American Education System Doesn't Fail -- this article - We don't need more STEM majors, We need STEM majors with liberal arts training --  shows both true wisdom and obdurately silliness.  

Yes, we need to double down on America's investment in "breadth" during college.   All around the world, the normative baccalaureate degree is three years, with 17-year olds diving into narrow fields with utter specialization. 

In sharp contrast, the American (and Canadian) Bachelor's Degree takes four years because all STEM majors are required to take a year's worth of humanities/history/Lit etc... and vice versa for humanities majors needing science survey classes. This article's author is only expressing the value system under which she was raised.  One with which I wholly agree! (As a "scientist/novelist" who earns his living across the entire spectrum.) You want MORE breadth?  Fine. I am down with that.

But to not even acknowledge that's already what we do?  Vastly more than any other nation on Earth?  Did you see her mention that? Even remotely?  Nope, just finger-wagging chiding -- the coin of our era -- instead of constructively pondering how to improve the miracle we already have. Pure silliness.

 == Predicting the Future ==

A reminder to you nit-pickers out there that I am willing to live by the principles that I preach! I have talked a lot about how we need “accountability for those who claim to predict. Actually, my fans have noticed the unusual number of "hits" or predictive successes that seem to have been scored in EARTH. These  accurate foretellings... and some that were embarrassingly off-target(!) are now being tracked at this site.

Feel free to suggest ways in which I have been wrong or right!  Not just in that one novel.

Here’s my essay -- Predictions Registries -- on why we should be doing this for everyone!  Especially politicians and cable news pundits and merchants of fear. 

 = And Finally =

What if...Ayn Rand reviewed children's movies? Hilarious!  

I really like the deep and original song by Big Data - “Dangerous.”  Their video is complex, layered and entertaining, demanding full attention: "How could they know, how could they know.. what I been thinking? Like they're right inside my head because they know, Because they know, what I been hiding..."

Then there’s this more shallow and yet deeply disturbing alternate version. Yeouch!

Resilience and Reliability - keys to tomorrow

Whenever I go talk to corporations, agencies or public groups about the future, one word I emphasize is "resilience." Try as you might, to predict the future and anticipate threats -- neutralizing enemies and preparing your professional responders -- sooner or later some surprise is going to hit, hard.  And when anticipation fails, resilience is our 'other thing.'  Our ability as individuals, families, communities to pull together and maintain islands of civilization -- till the islands can swiftly knit back together again.

That's the theme underlying The Postman, which was my answer to all the gleeful, Mad Max type celebrations of apocalypse. It's why I have pushed peer-to-peer text passing for our cell phones, and other simple reforms that could make a vast difference in our empowerment as citizens, to hang on, till help arrives.  Or to be the help for those across the valley, or the nation, or world.

 ==  Resilience on our rooftops and in our pockets ==

Why Elon Musk's Batteries Scare the Hell out of the Electric Company: “(Elon) Musk’s giant battery factory may soon become an existential threat to the 100-year-old utility business model. Beyond electric cars, the facility will also churn out stationary battery packs that can be paired with rooftop solar panels to store power." writes Mark Chediak in Bloomberg Business.

Musk's SolarCity Corp is already delivering solar panels and batteries to power California homes, schools, government agencies and companies including Wal-Mart, eBay and HP. Tesla plans to allow owners to swap old battery packs for new, with the old ones then being ideal to place in solar powered homes, helping them to get off the grid.

One thing I mentioned to Elon… and to sober-minded worriers in Washington: Currently a million homes in the U.S. with solar on their roofs will shut down if there is a power blackout. Instead of being islands of power for their neighborhoods, they are just another problem in an emergency.  

This is intolerable! Picture the increased resilience that we might gain, as a civilization, if those million homes could power just one plug in the kitchen, even during outages.  Enough to preserve much of the neighborhood’s perishable food and medicines like insulin, and to run re-chargers by-day, even if it shuts down at night.

This is a problem that’s a matter of national security… like making sure our cell phones have a backup, peer-to-peer text passing capability, if the networks go down.  I have only been preaching about this resilience issue for 30 years.  Maybe Elon will solve it because no one in D.C. seems to have a clue what really matters.

Want a hint of who has been blocking all this?  “The mortal threat to entrenched interests that ever cheaper on-site renewables pose” comes from systems that include storage, said Amory Lovins, co-founder of the Rocky Mountain Institute, a Snowmass, Colorado-based energy consultant. “That is an unregulated product you can buy at Home Depot that leaves the old business model with no place to hide.” And “In Germany, the rapid rise of tax-subsidized clean energy has undermined wholesale prices and decimated the profitability of coal and natural gas plants.”

Ah... yes,  I know some of you (dinosaurs) keep claiming nothing will change! Coal is forever! Fortunately, world changers like Elon are more important than cultish dinosaurs.

Are there other resilience techs that can make a huge difference? Tons!  And some have been reported here, like new systems for water desalination or purification. And local, self-made internet systems.  And the Maker movement, which is restoring can-do competence to new generations.  This should be a priority for our concerned leaders...

... and we citizens should insist.

==  Problems in our roots ==

Very interesting: Sex, Status, and Reproductive Success in the Contemporary United States. Contrary to the anthropological mythology that’s widely spread around, it appears that: 

(1) hunter gatherer (hg) and other low-technology societies have had inter-personal violence rates easily as great as contemporary city populations.  

(2) Those hg and low-tech societies had social stratification, hierarchy and dominance interactions that were statistically similar to modern societies, only without those modern societies’ accountability amelioration systems.  And (3) across the spectrum – even leading to today - high status males appear to both get more sex and reproduce more.

The last seems surprising, in the context of modern, urban society. But we should not be shocked.  This study teases apart high status from high education levels, in which there does seem to be a penalty, the higher you go! What is sad is that the sharpest effect appears to be on women with graduate degrees, whose repro success is severely diminished below less educated women.

 “…for men, intelligence works at cross purposes with income. For men, income increases both potential and achieved fertility, while intelligence decreases potential and achieved fertility for both men and women.”

We cannot get better if we romanticize olden times, or refuse to take into account our biological background.  We can and must choose to be better than our past, baseline modus operandi!  We can transcend best and improve if we admit the baseline was… and remains lurking… and deal with it.

==  Science Miscellany! ==

A clever notion for cooling our cities while side-stepping the greenhouse effect: “There's a kind of heat window in the atmosphere that no naturally occurring substance, trace gas or otherwise, can block.” So?  Use radiative rooftop cooling that emits in these wavelengths that bypass those absorbed by Methane and other greenhouse gases.  I am dubious in the short term.  Still, a “cool” concept!

A startup with $143 million in funding aims to create “a sentient distributed artificial intelligence that sounds like a nice-guy version of Skynet from the cinema flick Terminator.”  One step beyond neural networks? I have my own opinions on what might bring AI of various kinds and threat/opportunity levels.

What are the “Seven Wonders of the Modern World” - to hold up against the Pyramids and Great Lighthouse, of old?  Slate’s compilation ignores feats of architecture in favor of unseen miracles that allow people more leverage and power in life… like the vast network of undersea fiber-optic cables that give us instant connection across the globe, and the air traffic control systems that have quietly allowed us to stack incoming and outgoing flights at busy airports, like boxes on a conveyor belt. Drinking water systems… you get the idea… the things we take for granted.

Catch this: a new gear transmission mechanism with no touching parts, based on magnetic forces that prevent friction and wear and make lubrication unnecessary.  “The design uses a magnetic gear reducer, that is, a mechanism that transforms speed from an input axle to another in an output axle (as in a bicycle chain mechanism or the gearbox of an automobile). But unlike a conventional gear reducer, this transmission is produced without contact between the pieces thanks to the use of magnetism.”
