Which is exactly what what such a study would have led to, exploration of non-cylindrical fuel rods more resistant to blockage by thermal expansion. DuckDuckgo for such studies, there are a few but not enough.
Tigerdirect parent Systemax bought some compusa stores after their bankrupcy and are most likely monitoring the response to the alternate branding. Compusa became a nerds hell a decade ago, Tigerdirect was a change for the good, but is regressing to purgatory in the store I am familiar with. At least their web site seems sync'd with the retail stores.
More people is a good thing too? Everyone in the world coming up to US energy consumption? Another way to get more energy per individuals is to have fewer individuals. Now that would be progress!
The NRC view has historically been "if it can't be fixed it ain't broke". Thermal expansion of the fuel rods due to an excursion can completely block water cooling, whether in the reactor or in storage, thus no funding is provided for such studies. Maybe we live in a Brave New World, but it seems much like the Brave Old World.
I bet your proof will involve very short values of TIME:)
What the QC adherents don't seem to take into account is that detecting the quantum result is a statistical process. Getting those statistics may involve more time and energy than just running the calculation through a Turing machine.
Well...only in approximation. An infinite array of points emitting coherently will have arbitrarily narrow diffraction pencils which can miss the objective aperture, but fewer points whether coherent or not will always put some power into the image. Two points have an intensity dip of ~20% when spaced at the first Bessel zero, and 20% was chosen by Rayleigh as the *subjective* criterion for resolving two lines in a spectroscope, that being exact in the 1D case involving the first sinc zero. 20% continues to be used as the basic Strehl resolution of a lens with aberrations.
But any TV camera can do better than 20% if you crank up the contrast, and resolution is ultimately limited only by signal to noise. If you can track the target with no intervening atmospheric disturbances you can do much much better. Or so I suppose.
Paradoxically, high power does not automatically give long distance since it is usually coupled with modulation for high data rates. For device discovery low power with low bandwidth modulation techniques can give greater range. When you want to send data, switch in a LNA and change the modulation for faster rates.
Many 802.15.4 systems on a chip can do these things at $5 a pop; e.g. 250K to 2M bits per second, switchable 20dB amplifier, switchable antennas. It is just a matter of writing the software. Probably wifi and bluetooth also have such capability.
Agree that signal stength or LQI is no indication of distance indoors. Maybe the existing and proposed sub GHz bands would improve that, I only have experience with 2.5GHz. Fixed devices can report their location, "Fourth floor skunkworks chromatograph", but "Joe's laptop" is less informative.
Getting rear ended at a stoplight did the modification. Rust allowed the mounts to give way, nothing got bent and it would just slide in and out after that.
Getting parked in was common in Chicago in the '70s, but my solution was push-in bumpers on the old volkswagen. Of course I always had to pull them out after parking. In this case leave the car expanded and just fold to get out. Assuming they keep the nifty remote control feature, or that you're a contortionist.
Path of least resistance does not apply to electricity. It follows every field gradient and takes every path as fast as it can. The current through each path is limited by the reduction of the gradient caused by the charge already along the path, a.k.a. resistance.
TARP looks like a success on paper, but a big chunk of another $3 trillion was involved to prop up the assets of those companies so they could repay the TARP loans with subsidized valuations. Fannie May and Freddie Mac took the heat for a lot of those losses. http://pra-blog.blogspot.com/2011/03/true-costs-of-tarp.html
Free market could handle this were it not for the lobbies and regulations that favor big business. Why *must* automobiles have airbags and be built to survive impacts of 100 km/hr? So drivers don't have to worry about messing their hair with helmets? A $10000 car with 1000 km range could easily be fielded, and let the courts decide who is to pay when the occupants are smeared by an SUV.
A $3K electric bicycle can easily carry 200 kg with 100 km range at a top speed of 50 km/hr. It would be illegal in most civilized countries:)
We're not just lifting it out of the ground. We're exploring, drilling, fracking, refining, and transporting. Transportation being the killer for most centralized biomass processes.
Efficiency of solar panels has no effect on EROI per se. If it takes 100kWh to make a panel that will generate 200kWh over its lifetime that's a 2:1 EROI independent of the efficiency. But the point is that 5:1 is just enough to maintain automobile transportation as it is today, the energy to run the cars is a small fraction of the energy needed to maintain the infrastructure.
Not bashing the idea, but simply replacing fossil fuel is no solution. Sustainable transportation requires a sustainable infrastructure, and the estimates for the energy used for road infrastructure is somewhere around 4 times the energy used in fuel for the vehicles that travel along those roads.
That means the energy return on energy invested (EROI) has to be at least 5x if we are to continue to use automobiles for transportation. The EROI for oil wells within the United States dropped from >1000x for the first gushers to ~5x in 2007. Solar, wind, hydro have similar EROI limitations, so we will have to rethink the energy cost of transportation infrastructure if we want any energy left over to grow food or enhance our lives with cell phones.

Is E85 Dead Now?

As I understand it, along with the subsidy expiration is the elimination of the tariff for Brazilian sugarcane ethanol, which was being imported anyway to the US because of the higher tax credit for sustainable EtOH when used for making E90 (US production being exported to Brazil to pay for it). So ethanol will actually become cheaper! A few gas stations near boating facilities have been selling unblended gas http://pure-gas.org/ but most wanted the 5 cent per gallon credit for E90. Many small airports will let you buy leaded aviation gas for two cycle engines.
My chainsaw seized after overheating last month, after which I measured the ethanol content of my fuel mix to be 17.7% (add 100 ml of gas to 50 ml of water in a baby bottle, cap and shake well, read the water + ethanol level after it separates again). I am using $5/gallon aviation fuel in my new chainsaw. Using E85 voids the Husqvarna warranty!
Gandalf was afraid to take the ring because the promise of such power was too alluring. In the right hands (i.e. my hands) it could be used to right all the wrongs of the world. Would the Eagle chief be less susceptible? Would *you* trust him to destroy the ring?
Hobbits were resistant to the allure of power because of their live-and-let live ethics, even Gollum showing strength against the ring. The redolent Bombadil episode probably was left in solely to make the pont that the ring had no use for him, nor he for it. It would have been fascinating had Tolkien developed the potential of the ring to other groups like the treelike Ents. But maybe he thought the story was getting overlong.
A little bit of DucklDuckGoing will show that hospice patients, who are treated with painkillers and sympathy instead of aggressive testing and IV management, actually live longer for a variety of illnesses, including some cardiac conditions. When the end does come there is something to be said for dying comfortably at home with family instead of spending your last couple of days in a hospital bed cursing your caregivers.
Safety was pushed as a primary consideration, wrongly IMO but necessary to market a billion dollar device regardless of how many volunteers would be willing to take the risk. Sending a teacher just for the ride gave the usual result of excessive hubris, incidentally validating the 5% failure rate that any sensible person would have predicted from the start.
Since the danger you pose to others goes as m v squared, why not use the continuum instead of none or all. Under 50 km/hour in a 500 kg vehicle, text or pop zits all you like, and society even benefits through Darwinism. Above that be required to pay maximum attention so as not to endanger others.
Well actually two successive "photons" do interfere in a manner rather simply explained by classical electromagnetism but which can also be explained using QED through consideration of the correlation of their emission http://en.wikipedia.org/wiki/Hanbury-Brown_and_Twiss_effect.
When an antenna radiates RF a stupendous number of "photons" have to interfere constructively to generate the additive EM field amplitudes. Are such photons a sensible explanation of Tesla's ball lightning?

At a gigaflop per watt that's 24 MWh a day, $1.3 million a year in power bills at $0.15/kWh.
