Comment: Re:Small Airports Have Advantages (Score 3, Informative) 203

I would love to see these large airports replaced with multiple smaller airports. A larger percentage of the population would have an airport nearby, and average travel times would be reduced significantly. It seems to me that planners are optimizing for everything except your personal experience when they design and advocate for mega-airports.

There is a challenge with replacing all large airports with smaller ones, when using a hub and spoke model. If you have smaller airports, you have fewer destinations, and fewer connecting flight options. NYC (DC, LA, SFO, Boston) as a gateway to the US from overseas makes some sense - lots of O/D traffic, and for those that want to continue onward, they can. I fly from my local smaller airport, which I love. And whenever I can, I use my smaller regional airport. But it doesn't always reduce travel time - it often increases it due to the need to connect for most destinations. In fact, it'll be faster for me to drive to JFK (two+ hours) for an upcoming trip to eliminate a nearly three hour flight and one hour connection - in the "wrong" direction.

You can also install the Crashplan client on a device like a ReadyNAS - which would run 24x7 and not require their computer to be on. Offer to host one for your neighbor in your basement as well.

Bonus points for figuring out how to route between your house and your neighbor's without going to the Internet provider and back - point-point WiFi and a nice router?

I have a three-way backup scheme going, with our home computer and my parents' and in-laws'. We live close enough that if a catastrophic data loss occurred on one machine, it would be fairly easy to sneakernet over one of the backups, but far enough away that it would take a very significant event to affect all our backups.

Disney uses induction charging in (at least) three attractions - Ellen's Energy Adventure (formerly Universe of Energy) at Epcot, and two at Disney's Hollywood Studios - Great Movie Ride and Tower of Terror. (I imagine other Towers of Terror use the same technology, but I'm not familiar with them)

Ref: http://land.allears.net/blogs/jackspence/2010/10/universe_of_energy_1.html

For power, each vehicle carries eight automotive batteries. Of course, these batteries need to be recharged frequently so within the attraction’s two turntables are “charging plates” that contain electromagnets. The magnets work in conjunction with onboard magnets that create an electric current that is transferred to the vehicle’s batteries. No actual physical connection is made between the charging plates in the floor and the onboard magnets. This technology, although improved, can also be seen on the Great Movie Ride and the Twilight Zone Tower of Terror at Disney's Hollywood Studios.

Comment: 180,000 more pax a day? (Score 3, Interesting) 134

TFA:

The backscatter machines were pulled three weeks ago from New York's LaGuardia and JFK, Chicago O'Hare, Los Angeles, Boston, Charlotte and Orlando airports. The move was designed to speed up security lines at checkpoints there.

Sanders said it's worked and that lines at those airports are now moving 180,000 more passengers each day.

I find this confusing. Were the TSA lines the gating factor in keeping 180,000 passengers from flying each day? According to A4A, 2.4 Million Passengers will fly on 11/25/2012. 180,000 passengers is 7.5% of that figure. An average travel day in the US looks to be roughly 1.8 million passengers. 180,000 is 10% of that figure.

What did those 180,000 people do? Wait in line until it closed/they missed their flight, then try again another day? Decide not to fly?

I mean which free and open Internet apps can help countries and people move to better governments without warfare and fratricide?

  I mean serious applications that can facilitate voting, constructive partisan organization, democratic government and economic re-balancing?

I have yet to see any problem, however complicated, which, when you looked at it in the right way, did not become still more complicated. -- Poul Anderson
