The FAA regulates all of them in much the same terms-- lowest common denominator. While this was a puddle jumper, it was a Sky West/United Express flight.
I'm also a million-miler. It depends on the airline and how antagonistic the individual flight attendant is, but for a while United was making an issue with anything over 2 pounds (IIRC) not being stowed as carry-on luggage. They also take issue with anything not in overhead bins on the lie-flat seats.
Local record stores made money, but they were undercut by BB abd Walmart, who used music as loss leaders to get people in the store. As downloads grew, the retail market shrank, and hit the people making profit first. Downloads then further increased, making the loss-leader less effective, and leading to a decline in shelf space and therefore a further drop in retail sales.
The record industry needed to lower prices in the late 90's, but they raised them instead. They needed to embrace digital music at about the same time, becoming leaders rather than followers. Music became a commodity as a result.
My wife actually buys music-- a fair bit of it. (She is a spinning instructor and needs it for classes.) But she has enough of a base that she likely spends under $20 per month. She would have needed to spend 5x that to get the music she wants or needs if she bought by the album.
You might want to double-check that. Our Amex bills for our company break down items like Food, Drinks, Alcohol, and Tip for a restaurant, or Gas, Repairs, or Food for a filling station. It doesn't work for *all* transactions, but many POS systems seem to report it.
Since this keeps getting repeated, I will comment: the flight attendant should be instructing you to stow a large book, binder, and even your iPod sitting in the center console. They might not always do it, but that doesn't mean they aren't supposed to.
The issue is that they have disproportionally emphasized PEDs, rather than giving them equal weight with stowing everything.
Smaller planes do have issues, especially in pilot's headsets and static. While it was a Dash-80 where all 9 passengers and the pilots are essentially in the cockpit together, the pilot demonstrated the static in the headset, and explained the difficulty in hearing ATC and other aircraft during a GSM burst.
The best DC approach is 500+V DC distribution to the rack. The best AC approach is 400V to the rack. Either approach uses redundant low voltage power supplies at the rack level.
The benefit of DC is that you can stick dumb batteries on the bus (with an in-line charger) which eliminates a conversion to AC that would be required from a traditional static UPS.
On AC, the energy saving strategy is different-- do as little work as possible for as much time as possible, and run on "dirty" power until it is really bad. Or, you can use an AC flywheel.
From a distribution perspective, you can get 90% efficiency compared to a traditional 75% for a 480V double-conversion UPS going to a 120/208V PDU.
Then at the rack level you address power supply efficiency.
The idea makes a lot of sense, but the problem with either high voltage (500+V) DC or 400V AC is you have trouble getting the fault current down to under 5,000A per (US) code at the plug. Safety procedures are about 5-10 years out for widespread use of high voltage DC adoption in buildings.
I am honestly curious on this, but the optimist says many companies invested too much in a technology that ended up being superseded by a more efficient solution.
No, you just cover half the available area now, and the other half in 3 years. In 6 years, there might be enough of an improvement to justify selling your original install and upgrading with new equipment....much like many conservative investment strategies.
I was talking to a manufacturer recently, and they indicated about a 20-25% premium relative to SLAB's in terms of first cost. For deep-discharge applications, you would break even in 3 years when you need to replace the batteries.
If it's just as bad as everything else, then we can change it again.
...because taking power back from a highly centralized military organization isn't as easy as it would be under a democracy.
With democracy, you need a high incentive to create major change. That is a difficult barrier to pass, but not impossible. It is basically a means to a peaceful revolution through the election process.
Democracy fails because it is done in much the same way; we rely on others to give us a sound bite of what each candidate stands for. There is no *real* information on what a politician believes or will do, because of the nature of the political process to some degree, and ultimately the lack of benefit to their campaign to be honest and specific.
While the US is a mess in many ways, I think Thailand is a more interesting example of what happens when democracy is truly corrupted with lack of intelligence. I'm not even sure if I can explain why... but it is a good experience to go to the country during an election season and see for yourself. The one advantage they have over us is that the formal campaigns are only a few weeks long, but the power and organization of the political parties makes the individual candidate less critical to the process, and maintains a few real power brokers that are often out of the spotlight. (Much like US politics.)
More specifically, Kodak was in the consumables business, and the consumable portion was replaced with a non-consumable solution. They needed to find something to do with all of the businesses focused on consumables, but that was political suicide since it was 95% of their workforce.
No, what you have to do is spin your market segments into different public entities, and make the top level a holding company. Slowly try and divest yourselves of assets that won't perform long term....kind of what HP tried to do, only the exact opposite. (Or do exactly what they did, and try to be in management of Aligent...)
Metal halide lamsps don't dim well, so the typical solution is to shut off every other light. It takes several minutes to geet up to full power though, so you would need to know well in advance that a car is coming.
The autobahn was designed for higher speeds than highways in the US or UK. That creates fewer congestion areas which require greater visual acquity.
The US has gone nuts with highway lighting. The light levels do generally need to be reduced, but I have trouble believing this type of approach is the right way. They are shutting off alternating lights in Los Angeles in some areas, and it actually leads to fairly uncomfortable walking conditions, even in extremely low traffic, upscale neighborhoods.
You obviously have never started a business! The US is pretty safe on the balance given the rule of law. I've started and operated businesses in the US and Thailand, and investigated starting businesses in Hong Kong, Malaysia, Cambodia, Singapore, Australia, Sweden, and Ireland. While HK and Singapore (arguably Ireland, but that is a bigger reach) are much more tax-friendly than any of the others, each country has significant risks. By comparison, the US is the easiest place to make money and build a long-lasting business.
Now... there are plenty of stupid regulations that you deal with, and there are certain aspects of taxation that are fairly oppressive for a small business (namely being taxed on retained earnings rather than just draw or other money taken out of the business). The whole MAFIAA crap needs to stop, and patent law needs a makeover, to be sure. But, in your daily life you don't have to worry about who needs to be bribed, what regulations exist simply for someone to collect a bribe to look the other way... or what your competitor might be able to do to you without any recourse on your end.
Manufacturing is a different story. And, if you are doing anything borderline illegal, sure... you may have some concerns. Also, things change when your revenue is over a certain amount as to what place is most advantageous.
Specific to JotForm, they got screwed because someone was using their service for phishing. They discovered it, stopped it, and the SS shut them down in parallel. If they needed a service that was more resilient, they could have planned differently.
The moral of the story is plan for confiscation of equipment or domains when running an online business. Maximize resiliency.
The major efficiency improvement in large scale power plants comes from more effective heat recovery streams. You do lose some of that with smaller plants (on a ~100MW plant scale though it potentially a cut from 65% to 63% efficiency. Typical transmission losses are closer to 10% by comparison.
We are a long way from Mr. Fusion being economically viable for powering your car, but dropping from GW-scale plants to 100MW-scale plants is viable-- moreso if the plants are "maintenance free."
Apparently a mid-eastern venture capital firm committed $25MM to SCO to acquire their assets, and committed to funding them for 18 months from April 2011.

In terms of $/kW installed, it doesn't matter. If install makes a big difference, your half is denominated in kW and not area.

Conventional wells last much longer than 1-2 years, but horizontal frac wells are limited to about that duration.

Mining towns to today don't have any bearing on the argument. The concern is what happened 50-75-100 years ago here in relation to China today.
Unless, of course, you want to say that the natural evolution is for better workplace safety and rights over time.
FWIW, Apple's membership into FLA means that their suppliers will get surprise inspections in the future.
Fixed that for you.
