The Century's Top Engineering Challenges

coondoggie writes "The National Science Foundation announced today 14 grand engineering challenges for the 21st century that, if met, would greatly improve how we live. The final choices fall into four themes that are essential for humanity to flourish — sustainability, health, reducing vulnerability, and joy of living. The committee did not attempt to include every important challenge, nor did it endorse particular approaches to meeting those selected. Rather than focusing on predictions or gee-whiz gadgets, the goal was to identify what needs to be done to help people and the planet thrive, the group said. A diverse committee of engineers and scientists — including Larry Page, Robert Langer, and Robert Socolow — came up with the list but did not rank the challenges. Rather, the National Academy of Engineering is offering the public an opportunity to vote on which one they think is most important."

"Prevent nuclear terror"

[Sylos]

How is that an engineering feat? Seems more like a people feat.

The biggest challenge, by far

[stox]

Getting funding for the top 14 engineering challenges.

Getting funding for the top 14 engineering challenges.

Well that is the point of the exercise here, NSF trying to get money from Congress. But its more of an aspirational list of goals and the real problem is that the feedback system is out of whack.

You might imagine that either industry or academia would care about stopping Internet Crime, but what Industry actually cares about is making the numbers at the end of the quarter and the best way to do that is to make your bank, business or other crime target a less attractive target than the business next door.

Academia is meant to do basic research, but the measurement of production is minimum publishable units, publish or perish. And to get a paper published it has to be novel rather than important or useful. So we know how to do secure email in principle but nobody uses it in practice - across the Internet at least. The academics never quite finished the job and the incentives are not quite right for industry to be bothered.

Often an academic will solve a problem long before it is understood to be a problem. By the time the problem is recognized and the time is right to finish the job and make it useful the field has moved on. Nobody is going to get the credit for pointing out that Fred proposed a solution for a problem twenty years ago.

Most academic papers in info security are describing solutions to boutique cryptographic puzzles. Real world constraints are irrelevant. So at FC this year there was a paper that started with the idea of stopping counterfeiting of currency by printing barcodes on the notes. Good, interesting. The scheme then involved people scanning them with their cell phone camera. WTF ???? Wrong problem, the challenge the fed is trying to solve is to spot the introduction of fake notes quickly, they can do that with scanners in banks. The banks can be persuaded to install scanners but no consumer is going to spend time scanning their change at the convenience store with a cell phone.

I would add:

[Frank Grimes]

I would add: An electric battery with an energy density comparable to gasoline.

Who are these idiots?

* Develop carbon sequestration methods
No thanks, I'd prefer real alternative energy solutions.

* Restore and improve urban infrastructure
Could you be any more vague?

* Prevent nuclear terror
I thought these were engineering challenges.

* Advance personalized learning
Give me a break.

Re:Carbon sequestration

[Raul654]

First, diamonds are *not* a rare commodity. That is a myth that the De Beers diamond cartel has spent a century trying to create. De Beers tightly controls the supply, so that they appear to be rare. It's also a self-reinforcing myth - people think diamonds are rare, so they don't sell old family heirlooms, and thus there is no secondary market for diamonds.

Second, we already have the technology to create diamonds in a lab. See the wikipedia article on the subject. (At this point, I should mention that De Beers also tightly controls the diamond cutter workforce -- any diamond cutter who cuts for a company other than De Beers is immediately cut off from doing any De Beers work)

Re:"Prevent nuclear terror" - also

[sien]

Apparently nuclear war is just dandy. It's nuclear terrorism we have to worry about.

The declared nuclear states (and Israel with it's undeclared undeclared weapons) and their delivery systems and willingness to invade other non-nuclear states is just fine, it's the people with no weapons and little realistic hope of getting them.

Re:Carbon sequestration

[Dahamma]

The technology that's being talked about is carbon mineralifcation - the technology to turn CO2 into graphite, or diamond, or soot. That's would be a huge help in fighting global warming.

Hah. ok, the obvious problem with this is that turning CO2 into coal is the opposite of what we have been doing for the past 200 years. How do you accomplish that? Put the energy back into the coal! But if we could do that, the first thing we'd do is use all of that energy to replace the energy we still obtain by burning coal (and other hydrocarbons) in the first place.

So, it seems like the only way to do that is to solve the "energy problem" that is putting so much CO2 into our atmosphere already. Once we fix that, then the surplus energy can be used to remove all the CO2 we have already put into the atmosphere...

I understand that's a total oversimplification, but the point is: cure the disease, not the symptoms!
