As an individual you may not care much, but at a wider scale can be a noticable impact on power usage.
If every household in the US (~120m) draws an extra 10w average power, total requirement is arround 1Gw or 1 extra mid/large size coal/nuclear plant (E.g. Three mile island).
If you start adding all the devices you have on standby (inclucing some of the nasy cable boxes that drew upto 50w standby) it starts adding up. This is esentially where the EU regulations for standby power came from in conjunction that for most devices is it costs almost nothing per device to have it use minimal standby power just a bit or care and effort in the design phase of a hardware project.
* Ignore for simplicity that if running heating power is not really wastes, but if running household aircon essentially you double the power usage.
First issue is economics, fuel cost is 1-3% of launch cost. If you can only get half the payload weight to orbit but get most of your rocket back for reuse (and the first stage is the most expensive bit - 9? engines vs one for second stage), cost per Kg to orbit is still (massivly) cheaper.
Second issue is that the fuel cost for the first stage recovery is quite cheap, you only have to brake and land the engine and (almost) empty fuel tank so they are very light vs the lauch mass. From memory a while ago spaceX started using v2 of there main engine which was ~10% more efficent than the v1 engine; This gave enough increased performance that even with extra fuel to land and the extra weight from the landing legs etc. they could get the same payload to orbit plus do styage one recovery.
However this is not a liquid cooling system of the tiles. The (liquid) gas is pumped through the tiles to the leading edge where it is expected to evaporate. So worst case should be no cooling from the gas or the gas layer as a protective layer between the tiles and the incoming atmosphere.
If designed properly if everything works it is re-useable, and if there is a failure you would hope a production model would be designed to that the tiles would survive a single use even without any gas flow.
The UAC dialog does not actually appear on the users desktop. If is shown on the secure desktop (simular to the desktop you get on xp when to logon or unlock the screen) with a snapshot picture of the users real desktop shown in the background.
We have been looking into this at work, and it is pretty much impossible for anything running outside the core windows kernal to interact with this. I.e. no raising button press messages, so browsing of windows controls to find where to move the mouse, no access to the graphics even if you want to ocr the screen to fake mouse input. Essensially without installing custom graphics drivers (to capture screen) and mouse/keyboard drivers (to fake input the in not suppressed like all the hook methods) you not going to manage this (e.g. unlike xp system services with full privledges cant do it)
And quite frankly if you have installed such drivers you deserve what you get.
Now UAC as it is at the moment is a Pain in the arse (its off on by dev test machine unless i have a specific test to do) but give it a year or two for most open source & commersial application to get a new revision with proper Vista compatability (so all the pointless app dialogs stop) and i think it may work quite well at least to reduce comprimised machines.
Its major security issue is not really anything to do with the one in the artical, in short most of the prople who install Precision Time or some of the other crap they install from the web will enter there admin passord to install the app if required, because quite frankly a non skilled user if asked by their computer to do something (enter a password, click the ok button) will just do it. Might have some impact on things like worm spread/infection rates, because a worm on a machine would almost certainly need some user input to infect out, but the people who earn money from such things will just move over to a different method.
As i see it this has nothing to do with the site that has popup's being shown on it. Just as is i could choose to switch of the site background color in MY browser, or open a second browser window showing a competitors site, or setup a sript to popup a window saying "Armidillo" whenever i open a webpage. Then this is purly my choice as it is my computer.
Now if i have willingly installed some software that does the same thing, or opens some popup advert, again MY computer, i can do what i want. This is in effect what i see this ruling as.
Now the issue of whether the user has really given informed concent for this particular piece of software may be a completely different issue, and outside this ruleing (after all was in the eula oyou agreed to, however dubious asuch a thing may be).
For the analogies being used, if i want to wear a hat that whenever i look at a a house of a judge detects it, an card or heald out before my eye saying "American Justice Sucks", purly my choice as it only affect me, and i can choosen to install that hat on my head.....
Whatever you may think about the moral rights of downloading broadcast TV programs, i think you will find 'quasi-legal' is understatment. You are downloading copyrighted material without the permission of the copyright owner, which i think you will find is plain ilegal under US, Uk and probably all WTO signatury countries laws. (And no i doubt Betamax ruling to allow timeshifting would apply).
Now if you think this should be permited, then start speaking to your political representative/Senetor/Mp etc. and convice them. Or even the tv people direct, particually for non-us residents there is probably quite a market willing to pay access to TV serises for P2P (for a reasonable sum) rather than never see them.
Ah, but what if your leased apartment contains all your property, files for the buisness you run etc. If the goverment take the appartment *and all its contents* sure it might be up to the landlord to sort the appartment out, but it if definatly your right to query over the things within it that belong to you that were taken.
i.e. Surley in the eyes of the law leased property containing stuff belonging to you should be the same as leased server containing data belonging to you!
The main benifits of fusion (assuming it can be got working) are that it has the potential to be extremly efficent, using commonly available fuel.
It does however produce 2 types of radioactive waste. first the byproducts of the fusion reaction, and second the large ammounts of material in the reactor shielding ect.
The big benifit over fission is: a) Less waste should be produced b) The waste that is produced mostly will have a far shorter half life. From vague depths of memmory i seem to recall averaging about 100 year as oppose to 10->100 thousand years for fission byproducts. This means disposale is reasonable easy, as you just need a dposit to keep it safe in for few hundred years instead of the entire forseeable and unforseeable future.

The russion sea planes were nothing of the sort. when in 'flight' then did not touch the water, but instead flew extremely low (10->20 feet as i recall) at high speed. The planes were massive (as far as planes go anyway) as they used the ground plane effect to give them vasly move lift, this effect is caused when a wing is used very close to a flat surface like water or a beech (the seaplane could fly over both). The one I saw was powered by 12 large jet engines, all were required to get the plane out of the water initially, then half of them could be switched off for normal flight.
Note that these plane wew big, they could carry multiple tank and were armored with amored plate from the skins of ship, rather than the more usall planes aluminnum shells.
