An electrical heater is not a system, it's just part of one. The system itself would at least involve the energy source and the transporting medium, where the losses continue to hold true the fact that there's no 100% efficiency in any system. If there were, Entropy would have no meaning.
If you take the isolated case of the heater as being 100% efficient because in itself it's able to convert 100% of its input energy into wanted heat (which itself is discutable, since there may still be losses through electro-magnetic emissions, vibrations, etc. that would not be captured by the room and transformed into heat, even though all that would be as negligible as contesting gravity acceleration as not being 9.8m/s^2 in most cases), you'd just as well pick a heat pump which, with the same amount of input energy, "produces" 3 times more heat.
Heat pumps are 300% efficient. Maybe we should use heat pumps instead of electric cars.
What I meant is that the fact seems to be "electricity is way more efficient than combustion" rather than "electricity is 100% efficient. Gas is not".
As far as my ignorance in the laws of Physics goes, it's simply impossible to have any system running at 100% efficiency because it automatically implies zero loss of energy.
Electric systems lose energy everywhere: conduction materials have impedance, motors have friction *and* generate inductive impedance, photons are created...
I think you may have gotten your fact wrong.
Superman is an alien, brought to Earth on a spaceship, and has super powers. WHAT DID YOU EXPECT?
How about playing the evil guy to unite the Earth governments under a single goal and thus avoid the general destruction of humanity? Hmm, that sounds familiar.
Ok, I got it! Fight AGAINST the destruction of OTHER impressive things like the Great Wall of China, the Everest, Iguassu Falls and such, instead of DESTRUCTING a Manhattan-like city while fighting the enemy.
Thank you for putting into words what I have been feeling since I watched it.
What I kept from the film was interminable mass-destruction scenes with little care to a believable script. A waste of good character canon. I can't imagine why any significant number of (new) fans would look for any other merchandising or media after that.
Road maintenance is already a problem on many a government's budget. I have the impression that adding a complex system of energy delivery which includes encryption and selective power-up seems too complex.
I can understand why a group interested in justice and equality would expose the sensitive details of people in the databases.
I understand that as meaning "this group doesn't know how to pick their targets".
And it's not like there's not already a whole lot of danger and unfairness in South Africa -- the "net condition" will not really change.
So let's put people trying to make things better at risk?
(...)Pubic awareness and especially global public awareness will have been raised
The awareness I get from this is that hackers can give a huge blow against whistle blowers with no real "net gain" to any cause.
No, because it puts an end to "long term". To maximize entropy over time, one needs to keep as many options open as possible, so that one pushes the "end" to as far as possible.
Isn't it interesting, though, that if the Universe really follows this principle, that such a system would evolve into finite lives?
he took the design of the wright flyer and bolted wheels onto the bottom of it
The only thing the two designs have in common is that they both have wings. This is the model that Santos Dumont successfully presented in 1906. And this is the model that the Wright Brothers used to be the first to fly an airplane.
Note that Santos Dumont's model takes off on its own and lands, while the Wrights' model is launched by an external device and cannot land without crashing (since it doesn't have wheels).
(...) and you could pile on as many statements into that line as was sensible (...)
Actually, I seem to remember my MSX-Basic 1.1 to be limited to 255 characters per line of code.
I can't think of any particular ulterior motive that they could have to withholding a digital release.
Ok, what about "digital release makes it extremely easy for the consumer to decide which songs are worth buying"?
I suppose the 30kg Roman welfare might have changed also. But if we take the GP's hypothesis at face value and consider the outcome of the Roman Empire, I wouldn't say they were such a good example
