Higher Education’s Next Wave

I whole heartedly agree with a move to a system of incremental learning and a focus on mastery and relevance as discussed in this article. I even feel it should filter down into the post elementary, even elementary school, so that the line between home, public and private schooling becomes blurred.

It’s interesting that the Internet is leading to the disintermediation of an ‘industry’ once more, ‘getting rid of the middlemen’ who add minimal value while sucking $ out of the revenue stream (i.e. the now obscene number of administrators in education.)

Incremental learning would focus people more on life long learning instead of the ‘boost and glide’ model we have today, I know that I am a far better student today than I was as an undergrad and know far more about what I should be learning and could use. There are many people in mid career who if the education were available and cheap could potentially make career changes and add great value to society/industry if their practical knowledge were supplemented with more analytical/academic background.

Many (guys in particular) are still too immature at 18 – 22 to know what they want to do with their lives and have a hard time sitting through “bullshit” pre requisite courses that would probably do them much more good a few years (or a few months) down the road when they understand the value. It’s not like this is the last bulwark of good English, that line fell long ago.

One downside to this in some people’s minds might be the loss of ‘life insertion support’ that university provides. This has been a accepted (not always gracefully or willingly) part of a university’s job from their origins in the middle ages.

On the upside, does it provide the opportunity to look towards a trainee and apprenticeship model of life insertion? Our current over protective society has progressively withdrawn our offspring from the real world over the past 100 some years with the most radical shifts in the early and late decades of that period. This is making it harder and harder to ‘lifestream’ them.

The child labor laws today are blanket and draconian because that’s the habit from early on when otherwise enforcement was all but impossible. Also recognize that the laws were a form of price support for adults by getting cheap labor off the market. Today monitoring is much easier and safety really is important, why not let the kids start working at earlier ages, especially if they can structure education around their work schedule, and learn life lessons much earlier and hopefully more gradually. If education becomes a life long goal, like good health, exercise, good citizenship, etc, then the first 12 years of your public life could perhaps be much more fulfilling and broad as well.

What I have sketched here is a bit of a forward into the past scenario, this would be more like it was in the past before vast bureaucracies and their one size fits all models took over from the chaotic getting along going along organization of the nineteenth and early twentieth century.

We can perhaps see what is happening as the collapse of the bureaucratic model of organization as ‘the Internet’ and reasonably capable software eliminate the need for a one size fits all models which have tried to ‘adapt’ to an un-regimented populace by the ‘cushioning’ of thousands of special assistants, ombudsmen and administrators of this that and the other.

A few chemicals and a microwave and see what you get

Zapping raw materials in a microwave oven and drying the resulting solution produces a black powder (top) made of hexagonal bismuth telluride nanoplates (bottom).

High-efficiency thermoelectric materials could lead to new types of cooling systems, and new ways to scavenge waste heat for electricity. Researchers at Rensselaer Polytechnic Institute in Troy, New York, have now developed an easy, inexpensive process to make such materials.

The materials made by the RPI team already perform as well as those on the market, and the new process, which involves zapping chemicals in a microwave oven, offers room for improvement. “We haven’t even optimized the process yet,” says Ganpati Ramanath, a materials science and engineering professor at RPI. “We’re confident that we can increase the efficiency further.”

What caught my eye here is that the material is a form of nano particulate, its produced in an evidently very simple process and it has a very high efficiency.  This type of technology as the article notes could have a great number of applications.  In a car one could conceive of replacing the mechanically driven alternator with something like this or supplementing it, this would essentially be using waste heat to provide electricity and would increase gas mileage.  There are many other places where heat scavenging would make sense and have an impact if the materials and system were cheap enough.  This goes back to a fundamental issue, energy efficiency costs money and if the cost of burning a tiny fraction more fuel over the life of the system (which can add up to biggish $) is less than the energy scavenging equipment then the equipment will not be installed unless the added cost is passed on to someone. 

 

Algae to the rescue

Green tea: Joule Energy's SolarConverter turns carbon dioxide and sunlight into ethanol fuel at a pilot plant in Leander, Texas.

 Technology Review| Photosynthesis Fuel Company Gets a Large Investment:  Joule Unlimited will build a production plant for turning sunlight and CO2 into liquid fuels.

The company is combining many technologies to move to direct creation of biofuel precursor liquids.  The algae is similar to that others are experimenting with but excrete the molecules into the water instead of retaining inside the cells.  This way the harvesting ‘only’ entails fractionating the liquid from the flow.  The bioreactors are essentially double panel windows with the algae filled liquid flowing inside.  The water gets CO2 from a power plant which scrubs it out of the plant effluents and one guesses that in cooler climates the water could be warmed in the cooling cycle of the same power plant so the system could operate year round.

The company calculates that their system can produce a great deal more, more easily refined biofuel precursor liquids than the alternates. Which mostly involve growing various kinds of plants and then converting them to biofuels in either chemical or bio reactors.

Aerovironment micro UAV

20120116-223425.jpg

AeroVironment’s Hummingbird NAV shown in the palm of a hand to give it scale. The company has been able to fly the NAV (nano air vehicle) indoors and outside, including flying it through doors and down corridors into a workshop and office environment.

From the SAE aeronautics eNote. Not new news but best picture and ‘technical’ description yet.

AeroVironment has captured the imagination of a worldwide audience with news of a major extension of its activities into nano air vehicles (NAVs). Ever since human beings first discovered the basic principles of lift and the importance of wing shapes, the necessary muscle power and control movements of birds defeated all attempts to emulate the mechanical process of using wing flapping to beat gravity. The hummingbird’s amazing ability to conduct a perfectly stable hover has long fascinated students of aerodynamics, especially when slow-motion film footage displays the complexity and perfection of its ultrahigh-speed wing flapping movements.

Skynet it’s not yet, but one has to wonder…

Police Drone...
Skynet’s distant ancestor

The fact of the matter is that this, like so many other things, is coming.  I used to laugh at some ‘SciFi-ish’ cartoons for their depiction of flying drone/droid/robo cops, but then I’ve never been any better at predicting the future than most other engineers, we always dive way too deep into the details far too quickly unless we have something keeping our head out of the water long enough to figure out if we are in the ocean, sea, lake, pond, swamp or whirlpool. 

But there is the issue of privacy and the increasing ability of ‘the system’ to keep track of citizens 24/7/365.  Save a few puppies and a kid or so and we’re all for giving up a little bit of something for increased safety.  But at what cost, and have ‘we’ ever considered that we may be being manipulated?…..Anyway….

This post by Babbage at the Economist covers the ground pretty thoroughly, at least for the near term.  I think the killer app here is the comment about replacing choppers which cost a couple of million up to operate along with expensive maintenance and aircrew tails. Smaller police forces will be able to have an air contingent and big forces will have a lot of these things (hopefully replacing most if not all the choppers, which are IMO a waste of taxpayer money.)
 
UAV’s , particularly like the one in the picture have a lot of advantages they :
  • can fly in a wider weather window than crewed craft.
  • are harder to see and hear
  • can land and sit/monitor for long periods
  • could operate 24 hours with rotating crews or units
  • can travel ‘as the crow flies’ instead of around buildings, fences, traffic etc
That’s in the near term, 2-3 years, what about the middle Future (4-7 years)?:
  • Wide area surveillance from solar powered (maybe a SolarSaurs?) high altitude platforms.
  • Add ‘Gorgon’s Stare’ technology, constant surveilance with roll back capability.
  • UAV’s the size of a bird it could follow a perp under cover.
  • UAV’s that can launch a smaller pursuit drone with a TAZER ?…a bit like this
  • What about a humingbird UAV?

And as you add those capabilities my libertarian hackles go up more and more.  None of the above should be given by a free citizenry to a gov’t that is actively growing and actively misusing its powers or taking advantage of congressional stupidity.

…Maybe I’d be happier if…..I had the right to pot one of the little puckers if it was over my property without my permission?  Hey it would create a new market, for home ultra short range anti aircraft systems!  Maybe these guys would have a head start?

Creative destruction in it’s meme’s

20120110-232657.jpg Steve Jobs, our Guttenburg, RIP

VodkaPundit, via Instapundit, has a very good point to bear in mind in this the season of CES(RIP?)

When jobs came back to Apple he brought a self operational version of Creative Destruction, the dynamic heart of real capitalism we saw at work in the late eighties to early oughts, the idea that products, product lines even companies do not, should not, live forever but be overtaken by better solutions.

The iPhones 5 years old, it seems reasonable to think there is something next and no reason for it not to be targeted at eventually gobbling the iPhone as we know it.

What set of features would you build into a new personal product that might change the world?

The Instant Mall of the Future….an interesting idea

London’s new Containerized Mall

This  article A Walk Through London’s Boxpark, the Temporary Mall That’s Probably Coming Soon to a City Near You in the The Atlantic magazines Cities section talks about Boxpark, a containerized mall in london.  The structure are modified shipping containers with added insulation and fittings to make them into stores.  The whole thing was assembled on an empty lot in a few days and will be removed when construction starts on the building that’s going to go there permanently, in 5 years.  This is the next phase of the pop up store phenomenon, a pop up mall and there no longer needs to be an empty storefront available.  Also this would work to experiment with new store concepts, new locations, and even just to ‘freshen up’ or ‘change up’ a stale section of real estate. 

Also a dig for the Atlantic, which can be cranky liberal but is generally pretty even-handed and has some very good articles.  Their web page is pretty darn good and the Cities section has some fascinating off the beaten track articles.

Cool picture of a TerraFormed Mars

Awesome picture from this article. Wether we should TerraForm Mars. For you non geeks Terra = Earth TerraForm means to ‘adjust’ a worlds Environment to fit humans and life forms from Earth. Now on a world with existing viable ecology (life) this would be unconscionable but on a dead or dead ended environment I’d vote ASAP. … Arguments can be had on both sides, I just hope we get to have those arguments.

Future of Computing…Circa 2012…..

20111228-224416.jpg
Just eye-candy from APODnothing to do with computing

Several article/posts at PCMag.com that paint interesting picture of the near future. This one by M. Miller in Forward Thinking discusses next generation chips, tablet chips but also the direction of all chips. At the latest AMD chip conference

…strongly pushing the idea that the future of microprocessors will not be just traditional CPUs, or even the combination of CPUs and graphics processors (GPUs), but instead will consist of all sorts of “heterogeneous” processor cores working together.

In the article there were a couple of interesting tidbits….the doubling in speed with ~doubling of transistors per area faded over the last few years, one of the things driving multi core. Also today’s high end pocketable units have rough equivalency with 2001 supercomputers. Memory and peripheral speed obviously hit that raw performance as well as non optimized development environment.

Then this piece also under Future Thinking, discussing the direction of LCD and AMOELD and related technologies, there are several others not mentioned but this article is a good discussion of the near term mass production technologies.

Then there is an end of 2011 discussion by Tim Bajarin on the coming of Hybrid tablets, something like a Mac Air with a separable screen ~ tablet. I use my iPad (like right now) for a lot of light to medium duty tasks I once had to use my laptop, I sometimes use a Bluetooth keyboard (though not right now.) Can some one could come up with an ultrabook class laptop with enough additional functionality to make the added cost worth it? TB says he thinks WI 8 might be a leader, could be but iOS seems muscular enough….except maybe multi windowing…we’ll have to see.
