To me it a logical operation is part of an equation and symbols make much more sense than abbreviations. Mixing symbols and mnemonics just confuses things.
So what kind of zoning should be between the residential and commercial zoning? You will find that commercial zones abut residential zones pretty much everywhere.
If the datacenter was "not too noisy after all" then nobody would have complained/protested.
For some people any perceptible change in noise it too much noise. That is a subjective standard. The area is probably zoned for a certain noise level and seems to be within that objective standard.
Energy density may indeed be "the most important characteristic," but charge time, available power, and reliability over repeated charge cycles are also things consumers care about.
The biggest limitation on electric vehicles is the energy density of batteries. The other factors are important too but if there is not enough energy density the other factors are meaningless.
Perhaps with further research, their 10x energy density with 100% oxygen can translate into a 1.5x energy density in normal open air. I'd still be pleased with that.
It might be equally likely that the other components of air will make the batter not work at all. Even if they get a 1.5x energy density that is an incremental change and nowhere near their claim.
Have you ever heard the story of the boy who cried wolf? By making unfounded, sensationalist statements like this so often when a real breakthrough is found no one will believe you. That leads to less investment in real breakthroughs. It is already happening now. Look at the comments.
Now if a for profit company wanted to do this they would have had to do the following; 1. Environmental impact studies, 2. Local consultation 3. Easement/right of way purchase/contracts I am also wondering who does the maintenance/customer service for this system?
A local group just doing something is very different than a corporation doing it.
Go anywhere that ice melts slowly and you will see that kink of darkness in the fall. That dark layer is covered up by snow next year.The question is whether or not the snow is darker that is was. Has that darkness been increasing? One set of photographs will not tell us that and even photographs over they years will not usually suffice as exposures, contrasts, medium will make a difference. To make a valid comparison there needs to be a common reference that is in all the pictures so that the brightness measurements can be calibrated. I seems that the satellite did not do that.
Lithium-oxygen batteries, also called lithium-air batteries, have the potential to deliver the desired power thanks to a high energy density - a measure of energy stored for a given weight - that could be 10 times that of lithium-ion batteries and approach that of gasoline.
Energy density is the main overall measurement for the efficiency of a battery. It is the most important characteristic.
The "10 fold" statement only refers to one characteristic of a battery, and TFA states that there are other tradeoffs that may diminish any improvement.
Then why make the outrageous claim in the first place if there is little possibility of it coming true?
It also claims that lithium oxygen batteries are the same as lithium air batteries with they then contradict by stating that regular air does not work in the battery and that it needs pure oxygen.
the limitation of needing pure oxygen rather than plain old air.
This article spells of over promising to get research grants for something they already know won't work.
The difference is that articles like this claim dramatic increases, in this case 10 fold, that never seem to appear. Doubling over ten years is not a breakthrough. It is incremental refinements. The cost decrease is mainly due to economy of scale and refinements in manufacturing.
Sorry but how will they differentiate between the one who actually do the analysis and the ones that just click buttons to get the reward? I thought about speed but some people are pretty good a pattern recognition and will be fast.
rig strobo lights or loudspeakers or something to drive away whatever birds wander near?
Airports have been trying to drive birds away and have had little success. If jet engine noises wont drive birds away then neither will loudspeakers. Birds get acclimatized to situations.
Putting electric heaters inside a pump would make the pump more complex and therefore more expensive and prone to breakdown. See how the complexity of pumping molten salt around quickly rises?
Good job living up to your user name. I should have looked at that first before replying. Why should I have to figure it out your position when you could just as easily state it? Just because something is relevant does not mean you interpret it the same way I do.
This thread is about whether or not the school is a government entity. Since you all you did was contest my argument I assumed you has the same opinion as the other person I was talking with. How about you state your opinion at to whether or not the school is a government entity.
A school thet is 90% funded publicly and uses both US and Colorado flag on their home page is acting like a government entity.
Here is their description of a Charter School;
A charter school is a public school operating within a public school district. A contract with the local board of education allows a charter school to operate free from specified district policies and state regulations thereby allowing more flexible and innovative ways of educating children.
A " public school operating within a public school district" funded by the government sounds pretty much like a government entity to me.
I think you missed the main point. The problem is a government entity, the school, endorsing a candidate. The same person who made the school post shared that post along with an endorsement. Every time anyone sees the school post they will also see the endorsement. He could have placed a separate post on his page and there would be no problem. Endorsements are very valuable. A government agency is not allowed to contribute anything to a political campaign.
where the threshold falls where the guarantee of freedom of speech for one person crosses
Notice that the judge only had a broblem with the post on the school page.
Schaffer posted on behalf of the school, a government entity, a link to an article about a political candidate. The post was non-partisan, and factual and probably would not be an issue. He then shared that post in a completely partisan manner where he endorsed the candidate. Because he shared the post there is a link from the government post to the endorsement. Had he just created a new post on his page rather than sharing the original post there would be not problem. Schaffer knew what he was doing. Schaffer is a pretty smart man but not smart enough.
Aren't these tests required to get funding and not regulations and therefore do not fall under the 10th Amendment? If yoy dont want to do the test you just dont get the funding. Same thing with highway speeds a while back.
One trillion connections per year is roughly the size of the traffic the Wikipedia gets.
So one trillion is a big number yes. If there are ten trillion connections that make 10%. If there are 100 trillion that make 1 percent. If there are 1 quadrillion that make 0.1%. Do you see how putting the raw number as a percentage of the whole changes the significance of the raw number?
Wikipedia is one of the top ten sites
So what? That doesn't mean there are not millions of other sites that collectively get much more traffic than Wikimedia. What if Wikimedia traffic is actually less than 1% of internet traffic? We don't know.
What the judge is asking for is an estimate of the number of connections on the internet so that the 1 trillion number has context. He didn't say that they were insignificant. He said that the raw number, without context, is not evidence that they are significant. It is up to the one making the claim to provide evidence proving the claim. A raw number without context is not evidence.
Nitrate salts need to be mixed with other ingredients to become explosive. Nitrate salts alone are not explosive.
The most extended mixture contains sodium nitrate, potassium nitrate and calcium nitrate. It is non-flammable and nontoxic, and has already been used in the chemical and metals industries as a heat-transport fluid, so experience with such systems exists in non-solar applications.
The issue with birds is not a simple matter of using averages over an entire country. Solar plants like this are situated in desert conditions where bird populations are very low to start with. It is not valid to equate the impact of loosing some birds in a high bird population area with losing the same number of birds in a low bird population area. The problem with these collectors is that the brightness attracts insects. The insects attract songbirds. The songbirds attract raptors. Losing 1000 songbirds from a population of a millions is nothing. Losing a few hundred raptors from a population of a few thousand is a big problem. All birds are not created equal. These towers could cause the extinction of some bird species.
The Andasol solar uses an HTF fluid circulating in the solar field. This plant will use molten salt in the collector as well as in the storage medium. This is the big innovation of this new plant as it has higher temperatures and lower transfer loss. My concern is that pumping molten salt around is very different than pumping hot oil around. Oil does not solidify of the temperature drops If the salt solidifies in the tank it is no big deal. You just pump hot oil through the heat exchanger until the salt melts again. If the salt solidifies in the pumps and pipes between the collector and the storage tanks there is a much bigger problem. How do you melt salt inside a pump and hundreds of feet of piping? Another issue is that hot oil is nowhere near as corrosive as molten salt. With the tank method all you need to be corrosion resistant is the tank and heat exchangers in the tank. With the new technology every pipe, pump, solar collector, etc would have to be highly corrosion resistant. That can get very expensive and they may need to be replaced quite often.
A tank of molten salt with a couple of heat exchanges in it is very different than pumping molten salt around.
Take a look at this German production report. Take a look at page 248. That is a weekli production report. Notice that how much solar is actually already being produced. Notice that every day just before solar comes on and just after solar goes off there is a peak of production from other sources. Being able to shift solar production into those areas would mean less coal and gas being burned. As solar becomes more prevalent it becomes even more useful to shift solar production out of daylight hours.
