To be fair, LA is 266 miles away from Las Vegas; drive 1mph slower and you'll make it. Alternatively, they plan to put in a fast-charge station in Barstow (152 miles away) as one of the first 6 fast-charge stations just to make sure people can make it from LA to Las Vegas.
Many families in the US have multiple cars and only take one on a road trip at a time. Most families don't need both cars to be able to go 450 miles on a tank that's fillable anywhere in 5 minutes.
Most people live on the coasts, and are a lot closer to places they'd regularly drive to. You could drive from New York City to Boston or Washington DC on a single 265 mile charge. In southern California, you could drive from LA to San Diego and back on a 265 mile charge. You could even drive around the entire San Francisco Bay Area on a single 190 mile charge (the $60,000 version).
A large number of (wealthy) people in San Francisco, New York, etc. don't even own cars. Surely if they don't need a car then a limited-range EV would satisfy their needs. Sure, EVs aren't for everyone; but a lot of US driving done with gas-powered cars could be easily done with EVs.
That sounds really cool. Or hot since, unfortunately, the close proximity to its star means that it probably has a surface temperature of 1500 K.
I guess I'd be more interested in a different-sized planet a bit further away from its star.
It's not about the concentration (absolute or relative), but the effect. If someone started to double the concentration of O2 in out atmosphere from 21% to 42%, I would call that pollution because of the large number of negative externalities (ie. due to the impact it would have on forest fires). If someone increased N2 concentration from 78% to 89%, we'd all have a harder time getting to oxygen we need to function, so continued willy-nilly dumpin of N2 into the atmosphere would be pollution.
Actually, changes to low concentrations of greenhouse gases has a larger effect than changes at high concentrations. In a simplistic picture where the transmissivity of the atmosphere in a certain band depends on a single molecule, you can write the transmissivity of the atmosphere as I = 2^(-t/h). Where I is the % of the light that makes it out of the earth's atmosphere, t is the thickness of the molecule, and h is the level at which that molecule blocks half the light from making it out of the atmosphere.
Let's assume that 200ppm will block out half the light. At 280ppm, 38% of the light made it through. At 390ppm, 26% of the light makes it through. At 480ppm, 19% of the light makes it through. By 5%, basically no light makes it through, which means that from 280ppm, 480ppm is halfway to 5% and at 390ppm (where we are now) we are a third of the way to the effect of 5%. In actuality, every molecule has multiple absorption bands, and I'm sorry I don't have exact numbers handy. But, this exponential dependence is one of the reasons why methane, which is normally at a much lower absolute concentration, is a more potent greenhouse gas than CO2 (the other reason being that the ocean won't gradually reabsorb it).
When you submit a paper to a journal you typically sign a copyright transfer agreement. These vary a bit from publisher to publisher, but all of the ones I have seen state (and I just checked the two I have in my desk):
1. That the copyright (but not related patent rights) is transferred to the publisher, but the authors retain the right to make personal copies.
2. That it is original work, not published before in any language and is not being considered for publication elsewhere.
IANAL, but my understanding is that the first clause prohibits you from submitting the article to another journal and the second clause prohibits you from having already submitted it to another journal.
As far as I can tell, it's quite effective.
First of all, in 1000 hours (typical incandescent lifetime) a 60W equivalent CFL saves $5.00 in electricity, so if the price premium for a CFL is less than that, it's still the economical choice (assuming $0.11/kWh) even if it lasts no longer.
My main point is that the way various light bulbs (and CFLs in particular) burn out is actually a pretty complicated process, but LEDs are pretty much the best for most non-high-temperature applications (ie. oven lights), and that they aren't lying maliciously; your usage most likely just differs from their test process. The test process for CFLs involves something like turning it on for 5+ hours at a time, which is typical lighting use in commercial or industrial buildings, but in most people's home many lights are on for 5-10 minutes at a time (bathrooms, garages, halls, walk-in closets, etc.) so they are turned on/off 25 times as much for the same amount of runtime---which results in early failure because of the loss of emission mix. Alternatively, if the power from the grid is of poor quality in your home, the ballast or emission mix may contribute to early failure.
First, not everyone has a ID that is valid for voting* and making people who don't have one anyway pay to get one is basically a poll tax. Shouldn't an ID card required to vote be free?
*The following government issued photo IDs are not valid for voting: National Labs ID, State University IDs, Community College IDs, etc.
I don't know why no one includes summary's at the top of EULAs. It's not like it's that hard of an idea to think of and I've yet to hear a single objection (though I'm sure
By the way, this is suggested on page 2 of the article for all of you who either didn't read the article, or refuse to bother going to page 2 of an article that has no reason not to be on a single page.
