Okay, according to theory it is possible to use that heat. But it would be economically unsound.
Most efficent heat transfer can be achieved by convection using materials (fluids) with high absorption of heat (as water) and movement of said fluid (now hot) to the power generator. The size of the required devices would be the size of your desktop at least. At they would be expensive too.
And, as all thermal and mechanical processes, they are not 100% efficient (2nd law of thermodynamics) nor in the CPU side neither in the turbine side. So your generator would also dissipate heat (and it is noisy too).
As for the methods using temperature differentials, I am not expert but IIRC they are not so efficient or at least are slow (they need large masses of matter to be practical because the ratio of electricity generation / time is low). So, they could not transfer heat fast enough for your CPU to cool off.
"The books of chess, dice and backgammon", in old Spanish: "Los libros de acedrex dados e tablas" by King Alfonso X, the Wise, 1283 AD.
Book with an interesting introduction in the form of a tale. A Indian king asks 3 wise men which is better to have: intelligence or luck? and to show a concrete example. The first wise man says it is better to have intelligence, and teach the king the rules and strategy of chess. The second one says it is better to have luck, because with very bad luck, no matter how intelligent you are, you are doomed, and discuss the game of dices. The last one says it is better to have intelligence for deal with both bad and good luck, and shows this by discussing backgammon.
Your conclusions are interesting. But I can not understand what do you mean by "when to think"... A "professional education system" is not also intended to teach "how to think"? or by "professional" do you mean "trade school"? Please, show some examples that could explain your points better.
that his ADSL line in real life can download at a speed around 20 Mbps, 40 Mbps is the best case, but because he is lucky and lives at only 1 block from the NTT building, where the access point to the national or regional backbone is installed, and it may act as a hub for his city (small city). He also told me that people 2 km farther from the hub would get only 2 Mbps in average.
Why the cost of living in USA (or any First World country) is expensive and why you can not bring it down? I am not American and I have been there only once in my life for only a week, so I don't know much about life in the USA. But I suppose that if the unemployment is high and people stop spending for fear of being layoff, then nobody buys and the prices must go down. What is stopping prices from going down? What components of the average american's cost of life are not getting cheaper? I would guess medical services and real state, but soon or later those two will be cheaper, or I am wrong? In that moment, I suppose that the cost of living and the salaries would get in line with the rest of the world, and any advantage of cheap labor would be lesser.
Yes, It's not going to happen again. Like in Ender's Game: "this is going to work only once, so let's do it big", speaking about the MD device. Once your enemy knows your new trick, you can not use it again. The terrorist will have to invent new tricks.
Wireless power transmission has already be done, I think, or has been finished in the drawing board at least, to transmit power between satellites and ground stations, using microwaves and arrays of antennas. The problem is to build an efficient, multi-purpose power transmitter. Small devices has not enough area to put an efficient directional array of antennas, and it would require some complex circuits to change the directionality when you move the device around the house. Wireless power transmission is not the norm because it radiates a lot of wasted power into the space, and your neighbor can use part of your power without pay for it (poor Nicola Tesla).
There simply is no other way to rectify this issue. Even if the US pulled out of the Middle East and swore off the oil habit and simply ceased dealing with that part of the world. The minds behind these murderous fundamentalists would not change. They would still plan their assaults and still carry out what they are able to carry out.
Yes, modern reality is harsh, and sometimes no perfect solution is possible. Overall, I agree with you except in the point of pulling out of the Middle East.
If USA pulls out its forces of Middle East, the terrorist, fanatics and fundamentalist zealots will be really busy the next 10-20 years overthrowing the Gulf goverments and installing theocratic goverments like the talibans. So, I think the western world would be quite safe in the short term.
The problem is the next years. Because then they would use oil price and supply as a weapon, first to isolate Israel and create a Palestinian state. Then, they may content themselves with easy petro-money and cultural isolation, or they may try to further the spread of Islam by force or by money.
Of course, the real solution would be to ease the dependence on oil, but there is a lot of Big Corporations what stand to lose a lot. They have big long-term investments in oil dependant industries, so that will never be possible. And the American electorate will not be very pleased with the goverment in the big economical slump because the structural adjustment (just remember what happened to Bush Sr.)
We need to analyze this move from MS. Many goverments want to be sure there is no backdoors or time bombs hidden in the OS (for the sake of national security), and they are beginning to look toward Linux. So MS needs to counterattack and it offers some access (read only) to the source and customization of encryptation. But if they want the goverments to forget Linux, they will need to disclose ALL the code, because a back door could be hidden anywhere. No matter if the goverments sign an NDA, some information about the source code is going to slip outside. Specially the premium and hidden APIs that MS uses to have an advantage against the competition in the applications business. That APIs allows MS to get better features and integration months before the competition can catch up. But if they begin this program, they can say goodbye to one of their main (unfair??) advantages in the application business. Well, it is better for MS to lose only part of the applications business than both OS and application segments.
Translation Lima, Peru June 17 2002 Esteemed Sir, I have the honor to address you in order to express our concern about recent proposals in the Congress to limit the Peruvian Goverment's adquisitions to only "open source" software or "free software" (Note: free as in freedom). I consider important to remark that our Goverment (USA) does not oppose the development of that type of software. In the contrary, we support a free market in which this software and patented software - both locally produced or foreign produced- can compete directly such as the best product can satisfy the need in the most appropiate way. If the patented software is excluded of goverments purchases, it would cause a serious effect in the growth of Peruvian software developers - a industry with the potential to create 15,000 new jobs in Peru. Therefore, that exclusion sends a confusing signal about investment policies to foreign corporations looking to expand business in Peru. In that ground, I beg you to consider a law offering opportunities to a level playing field competition for both free software and patented software.
