    I don't even think they can beam power to large (i.e. passenger) aircraft with any nominal success. I encourage you to look at the power output of large jet aircraft - enough power to power a good chunk of a city. (The 777 has 98000 lbf thrust and can go approx 557 MPH at 35,000 ft. This equates to about 108 megawatts - assuming the engines are going full bore at that speed - yeah I know the thrust is probably static thrust at sea level, so it might not be anywhere near 100 MW at altitude, but it's probably still on the order of 10s of megawatts). I don't know about you, but I don't think we have 100+ MW lasers that we can be firing around at aircraft - even if we did, throwing 100 MW at the area of an aircraft would pretty much melt just about every good engineering material of which I can think.

    This is a neat idea, but I don't think it will ever replace fuel-laden aircraft for transportation or cargo. I think the article was right in that it metioned unmanned, lightweight drones flying slowly over a city.

  3. Smallest visible object on the moon from Earth... on New Solar Cells 20 Times Cheaper · · Score: 1
    Umm... the eye doesn't work by seeing a percent of area - the eye has a working resolution, like a digital camera. The question is, what's the resolution of the human eye, and what's the smallest thing that can be resolved by that resolution at the distance of the moon?

    This Article indicates that an average resolution is either 4 arc-minutes or 6 arc-seconds. The 6 arc-seconds makes more sense than 4 arc-minutes (4 arc-minutes is a whopping 1.2 mm at a distance of 1 m (I don't know about you but I can see better than that!), where 6 arc-seconds is 0.03 mm (about .001") at one meter. I don't know about you but I can see a 1-mil thick object at a distance of 1 meter (think piece of paper or something seen edge-on - if lighting is correct). According to this, the moon is 3476 km diameter and averages 384,467 km from the earth. That means the moon covers 31 arc-minutes. 6 arc-seconds at the distance of the moon is 11.18 km. So, your 617-square-mile city will be more than visible, since it's surely larger than 11.18 km in one direction. (sqrt(617 sq.mi) = 24mi on a side = 40 km, so you've got a fudge-factor of 4 on my calculation to be visible. Even your smaller cities of 400 sq.mi. are 20 mi/side = 32 km, or a fudge-factor of 3). (This should also prove that we can see better than 4 arc-minutes, since if the moon only covers 31 (This confirms an average of 31 arc-minutes), we sure can see features more fine than 1/8th the diameter of a full moon - even without magnification!)

    Wow, I keep getting more comments, so here's an attempt to sort some out. And yes, I know I made some gross assumptions and some odd statements about physics, but they're not baseless...here goes:

    Where'd you get the 5kW figure?

    Most houses (well, the last four in which I've lived, anyway) main breakers are rated at around 60 amps. 60 amps times 120 volt mains is actually 7200 W, which is higher than 5000. Usually people don't trip out their mains, though. So 5kW was probably more of a capacity than a usage. Suffice it to say that while the average might not be 5kW, the average peak load is probably 5kW or more. You realize how much power you use if you've ever been in an RV...just running the A/C and the microwave will trip a 20A breaker (2.4kW)

    On seeing stuff on the moon...

    Okay, maybe I do have uncanny vision. Considering the power on my contacts is -2.75, though, I doubt it. Yes, I know that we look through our atmosphere to see the moon, but the lensing effects are very different looking out rather than looking in. And the comment regarding color is correct - sort of. Currently we do see mostly the moon's brightness, and the gross color. It would be hard to make out the color of a large structure, but it would definitely change the appearance of what we see. Sure it might be cool to see a "great monument", but I'd also feel morose about something on the moon. And man-made things don't look like craters (unless we spend extra, I guess). As for building on the dark side... well, I might not be able to see it, but there is then the moral dilemma...

    And In summary....

    Basically this was a semi-technical rant about power consumption, over-commercialization of rare resources, and stuff like that.

    I echo this one. The big issue is not cost of solar, but area. After all, the average home uses about 5kW . A typical estimate of solar load is 1 kW/m2. That means, even with 100% efficient cells, you'd need 5 square meters (~53 ft2) to power your house. Not to mention you'd need more than that to store power for night, cloudy weather, etc. That's going to eat up a lot of roof space... and need to be protected and cleaned as well.

    Yes, being a "valued comanpy" has an effect on the cost of capital - but investing in the company does not affect credit ratings. And if you look, stock price does not determine credit ratings; credit ratings are usually determined by performance (well, expectations of future performance, really). Stock price and credit ratings are supposedly indicators of the same thing, but nobody ever raised the credit rating on a company simply because its stock price went up (at least not that I have observed). So I would have to disagree with you there; buying stocks does not help a company's credit rating. Purchasing goods or services, however, will affect credit ratings: - if I buy a company's product, it gets more revenue, which analysts like. Buying more product will reduce the cost of capital and increase the stock price. Of course, buying a company's product does not always guarantee anything; sometimes companies that post profits with high revenues even get downgraded because analysts typically have depth-perception issues when it comes to analyzing companies' performance.

    Of course, stocks and credit ratings hardly behave in a logical, rational, deterministic manner; they behave the way they do in a disturbingly self-fullfilling and self-realizing fashion. (loosely tied to the performance of a given company or industry).

    Anyway, I think people are forgetting the real issue here. Here in America we have a market economy, and currently people are "paying" ISPs and CD burner companies rather than record labels to get access to music. There is a moral issue here in that ISPs and CD burner mfgs don't give money to artists, but Record Labels do.

    We live in a society where the ubiquitous "content" can no longer be controlled by media distribution, because there is no longer a need for physical "media" on which to transfer the "content". The "media" which is now controllable is the hardware on which the media is played rather than the media itself.

    Think of it this way - before you would buy a record player / tape player / ??? player - some small up-front cost. Then you paid someone to give you a device of some sort which the player would be able to convert into movies or sound or whatever. The producer of the 'small device' was able to pay the "content-creator" based on volume sold.

    So, what have we now? We've got some companies trying to sell devices which aren't needed to get the content consumers desire. Here's an interesting solution:

    ISPs become Record Labels (or Record Labels become ISPs)

    Think about it - you pay your ISP to connect to the Internet and then browse as you feel fit. What if the ISPs had to pay each (commercial content) site to which they served based on the amount of traffic to that site? And what if your ISP bill reflected that? Maybe more artists should work out contracts with ISPs to this nature.

    *GASP* you say! That means they track where I've been! They will know what content I use!

    So you're telling me when you go into Best Buy and plop down $10 (okay, maybe $20) for a CD that's "anonymous"? We (or at least some of us) live in the USA so there is nothing to prevent someone from standing outside the store and knowing that we frequent Best Buy. Also, we don't mind paying "per item" at a grocery store. The same idea of "pay an ISP some fixed amount per month and get as much of all content as I want" would be akin to paying your local grocer a monthly fee but being able to go in and empty the entire place. Hardly equitable, and it definitely seems silly when you think about physical property like food.

    Why is it that people seem to think that if it doesn't have mass and can be beamed around over the internet, it's not real and paying for it is silly? Well, that's only part of the problem, so I'll not linger on it.

    If you're observant, you will note that this (setting up some arrangement with an ISP type place and distributing obtained funds based on content selected) is not a new concept. Some companies (Apple, for instance) actually already do this, and customers don't have a problem with it.

    I could definitely write a dissertation on this topic, but suffice it to say that I understand that people have a problem with the RIAA yapping because they don't get revenue because they have an uncompetitive business model and are resorting to litigation (hrm. sound familiar?

If you really want them to change their prices (and I think I read somewhere that one label is dropping prices), STOP BUYING THEIR PRODUCT!

In physics, one manifestation of an increase in entropy is an increase in the temperature of a gas with a pressure increase that is lower than it would be if it were isentropic. That is, you put in some energy to increase pressure to do some work, but that pressure cannot do as much mechanical work as the energy you put in.

    Well, I know that starting new threads is discouraged, but I didn't think this fit in with any ongoing responses, so here goes one of my usual tirades on the poor use of semantics...

    Analysis of the Issue

    Regardless of the "fault" of piracy, here's an interesting thing I have noticed with most industries where something can be pirated - music, software, literature, movies, and the like. They always claim that "piracy cost us N dollars". Now, how can this be the case? Generally, when you think of "cost", you think of a sum that someone must pay. For instance, when the automotive industry says "warranties cost us $2 billion" it makes sense, because they must spend $2 billion of their own cash to cover the warranties. That means they have to take $2 billion they already have and spend it on something.

    Compare and contrast with "lost sales due to pirating". The music / software industry does not have to give any of the money they already have because of piracy. They still sell some number of product, and obtain revenue from those things they do sell. The question then becomes, if there was no piracy, would they sell more items and thus increase their revenue?

    Any person with a good business brain should see that piracy is not a cost in the strictest sense. It is simply untapped potential, or evidence of a poorly priced product. It is simply supply and demand. The public is willing to purchase a number of items at the set (by cartel or whatever your opinion my be on that one) price. There is demand for more product, but not at the going price, so the public finds an alternative. Because there is an alternative, at a much lower cost (the cost is not dollars but risk associated with ownership of unlicensed product), some people choose the alternative.

    A New Business Model

    A good solution, if the content industries were real business-savvy, would be to find the price at which they would sell the volume they want to sell. If they cannot make ends meet at the revenues they are currently getting, they should implement some other form of cost-cutting or whatever. And in the content industries, cost of distribution is almost zero - CDs cost pennies each, and packaging, printing, and shipping are also insignificant. (Proof - go to NASDAQ and look up M$s financials - note their revenue of $28 billion and cost of revenue is only $5 billion - gross return of 460%. (Constrast with Ford - revenue $165 B, cost = $125 B; gross return 32%) )

    This means that their business structure is not right - they have too much overhead, or are too greedy. Their cost/pricing structure is not sufficient based on the demand for their product at the prices they want to sell. Sure, they will yap that if they sold as many CDs as people are downloading, at the price they want, they would get N more dollars. However, to sell that many more CDs, they'd have to drop the price and only then get M more dollars. But, if by dropping the price 5% increases volume by 10%, then they'd end up with more than they estimate.

    Hypothetical Finances

    Let's say for instance that CDs would retail for $10 each, say $5 wholesale. If you sell 100,000 copies, that's $500k. I'm guessing production costs are around $50k for tooling and such and $0.01 for each disc at that volume - or $1000. So cost of product is only $51 k. I don't know what labor is to make 100k CDs, but I'm guessing the machines can crank out 5000 / day for sure - that's only 20 days of production. At (auto) union costs of $50 / hour, say for 10 employees for those 20 days, labor would cost $80k. So now our total cost of producing those 100k CDs is $131k. That leaves $369k to split between the band (estimate 5 people) and label people (how many does it take to get a record going? Let's be conservative and say it takes 20 people).
