I used to live 8 miles from MIA, and I thought it was bad, but walking 10 blocks south from my house I met the people who really suffered, they got the climb out blast pointed at them on over 1/2 of the northbound takeoffs.
I moved 16 blocks north, not really to escape the noise just to get a bigger house that I could afford, and it was like another world - you could still hear them, but they were never too loud to talk over in a normal voice.
Show me one school that will take the time to monitor what kids are learning online... they won't, it's boring for the teachers / monitors and they'd much rather shut it all down rather than take the chance that a 7th grader will pull up a picture showing a nipple, or maybe learn how to trade (illegal).mp3 files, or find the instructions on how to build a pipe bomb.
The teachers are outnumbered and under-motivated to oversee any kind of free-form dynamic interaction between students and the real world. There's too much danger out there.
Anyway, the only lesson they really teach in K-12 school is to "do what you are told to do." Everything else is just a pretty window dressing on that single concept.
FedEx used to throttle up for climb out with their engines pointed at my house, the windows would rattle for 2-3 minutes. How do I know it was Fed-Ex? because I complained to the airport, they took the information and sent me a radar track with an ID of the aircraft that matched my complaint time and location. I asked if they were going to do anything about these jets that are making a mockery of the intended flight path (climb out was intended to be over water, but being a cargo jet, they would pull it hard left as soon as they passed the "gate"), answer was that they would continue to track the planes and please keep the complaints coming, because it justifies his job as complaint tracker (translation: no,...or, are you high man? we can't do anything about how the pilots chose to fly their planes - it's called air traffic control, but it's really more like a polite request).
Lucky you, the AMC theaters around here typically have light pollution behind the screen and cracked speakers that are still turned up too loud. But, hey, what do you expect for $9/ticket?
Ok... point taken, but you must agree about the deaf guy also feeling it go by. Also, it's kind of hard to hit a target when you're pushing close to Mach 1.
Central... some places in the everglades, and really all the way up to just south of I-4, there are places you can get a several miles away from the nearest roads with 40MPH+ traffic. We've got a place in Desoto county where we camped out one new year's eve and listened to a couple have a screaming fight over 1/2 mile away, they were just a little louder than the passing jets.
Sure, they will never be silent, but they haven't been doing much improvement in the last 30 years. The old 707 engines were remarkably loud - going to turbo-fans made a big improvement, but I feel like they haven't made any further reductions since the "hush kits" of the late 1970s.
The entire Florida peninsula is severely noise-polluted from aircraft. Even when they are flying over at 30,000 feet, they're louder than the breeze in the trees, or an idling car engine, 6' away. If they can reduce the sound output to where the noise from a jet at cruising altitude is less than normal ambient noise in a suburban neighborhood, that would be a big accomplishment. I doubt they'll get it down to where you can't hear them while standing in a quiet field away from air-conditioners noise of passing cars - but they can try....
Also, don't forget the military aspect of this - F4 Phantoms were intimidating, but they certainly wouldn't sneak up on anyone, even if the person was deaf they could feel an F4 coming. F16s are a huge improvement, noise wise. I've never heard a stealth fighter in person, but I assume their noise signature could be reduced too. A fighter jet capable of silent approach and supersonic response speeds would have plenty of applications.
I really don't need 1080p to enjoy a movie. Most theaters I've been to lately seem to have about 600 line equivalent resolution - really big screen, but not too sharp.
I buy my music on CD - still - because I am used to being able to copy them onto MP3s using tools of my choice, at compression quality of my choice, without DRM. Yeah, downloading an.MP3 might be easier, but the bulk of my CD collection is 20+ years old, I can't imagine keeping track of a DRM restricted song file that long, therefore it is of much less long term value to me.
If I want short term music enjoyment, I'll listen to the radio, or lately net-radio, or actually go see a live performance. If I'm buying a copy of music, I expect that copy to be durable enough to pass down to my children, just as I have inherited 78 RPM Pathe' discs from my grandparents.
They (managers) would learn something, once in awhile, usually after screwing it up for months on end. In addition to stretching the labor laws, my favorite was their way of backing out the sales tax from the night's receipts - one of them had been trained to multiply by 0.95 to get the before (5%) sales tax figure, I suggested that dividing by 1.05 might be more accurate, but that was unthinkable because they had to follow their training... One of my less favorite experiences there was the periodic mixing of bleach and ammonia in a hot mop bucket by some new kid, I don't think there was any permanent tissue damage, but it got really unpleasant several times - I simply refused to enter the area, wasn't popular the first time I did it, but after they stayed in for about 5 minutes they came out too.
To give some fair perspective, these "managers" were about 22 years old with maybe some courses from the local community college... running on "common sense" more than any actual knowledge of the world. Sort of the ignorant riding herd on the naive.
This had nothing to do with labor laws, this was scheduling the employee to work from 4-close, telling them on arrival to not clock until told to do so, which might have happened at 4:15, 4:45, etc. They'd also pull it in the pre-close lull, asking people to take unpaid breaks when there weren't any customers. If you pushed back they were "only asking," but a lot of the kids didn't know that.
Yep, I worked in a scumbag fast food operation that would tell their high-school kids to clock out and take a break for 30 minutes because it was getting slow, this to save the price of a large soda in labor expense. You can scream to whatever labor watchdog you want, but the easy thing to do is just walk away and find a real job.
Would be a tough call for me, if I were living on a 50' boat with the thing. I'd rather sit on diesel tanks than gasoline, but I'd also rather not listen to a diesel run, kinda defeats the point of getting out with nature.
And, can a diesel really generate 2400W on 1/5 gallon per hour? My (admittedly, portable gasoline) Honda generator will suck down roughly 1/2 gallon in about 3 hours if its loaded up to a continuous 800W. That 11% figure also includes generator efficiency, or lack thereof.
As for sending it off to NZ for servicing, that's not a design fault, just the present reality of what's popular in the market. Will Sterlings gain popularity? Probably not, but that doesn't mean they are a flawed concept, or impossible to execute. Rotary (Wankel) engines are superior to piston in power to weight ratio and packaging size, but they never took off, except in certain segments of the light aircraft market. Wankel is hardly a flawed design, and if it were developed to the extent that the piston engine has been, it could make strides in efficiency and its other shortcomings, but it has been mostly forgotten and lags in development roughly back where the piston engine was during WW II, it has seen some basic refinements, but nothing like the billions of hours spent tweaking pistons & valves.
Simple, at least for the egg-beater type turbines, just put a giant disc (aka migratory bird stopover pad) just under the blades and run the magnets around at high speed vs a large number of stationary coils.... minor problems with cost in the coils, and magnet structure, and beefing up the tower to handle the giant disc and its potential windloads, but otherwise - it has to work!
...how something like a CVT would work for a wind turbine.
About as inefficiently as it does in a car. The electric generator has a wide range of RPM in which it can operate efficiently, so you'd be better off with an efficient fixed ratios gearset if you wanted to have a mechanical transmission. Personally, I wouldn't want any gears in the generating system if I could manage it.

That's the ticket - now, we need Fed-Ex to start flying these instead of creaky old 727s to shuttle our eBay purchases around.
Key word: approach
simple physics there, all supersonic approaches are silent, even the in the F86 .
What would be useful on a strafing run would be to fly at something just over stall speed and still sneak up on your targets....

Dunno, I have tons of media that plays fine in Linux, I just didn't try to purchase any of it from downloads@wal-mart.com

I'm still running Tiger on a 2006 MacBookPro - works as well as it ever did.

My new Eee Box tops out at 17W power consumption, and it can play games just as advanced as the Wii can...
Hey man, that swirly thing behind the XMB is majorly important to our cultural heritage... well worth the boxcar of coal it consumes every month.
Yep, I was just thinking that, although Folding@TheServerFarm would probably emit a similar amount of carbon per calculation performed.
PS3 is a space heater at 150W+, and a 42" LCD only draws about 70W, but, yeah, turning it off is the answer, just like anything else.

Yeah, those killer whales are just soulless machines because they don't look like us.
