  2. TFA is nonsense anyway. The actual paper appears to be this one: http://pubs.rsc.org/en/content...

    The abstract says:

    We analyze 36 years of global, hourly weather data (1980â"2015) to quantify the covariability of solar and wind resources as a function of time and location, over multi-decadal time scales and up to continental length scales. Assuming minimal excess generation, lossless transmission, and no other generation sources, the analysis indicates that wind-heavy or solar-heavy U.S.-scale power generation portfolios could in principle provide â¼80% of recent total annual U.S. electricity demand. However, to reliably meet 100% of total annual electricity demand, seasonal cycles and unpredictable weather events require several weeksâ(TM) worth of energy storage and/or the installation of much more capacity of solar and wind power than is routinely necessary to meet peak demand. To obtain â¼80% reliability, solar-heavy wind/solar generation mixes require sufficient energy storage to overcome the daily solar cycle, whereas wind-heavy wind/solar generation mixes require continental-scale transmission to exploit the geographic diversity of wind. Policy and planning aimed at providing a reliable electricity supply must therefore rigorously consider constraints associated with the geophysical variability of the solar and wind resourceâ"even over continental scales.

    Which contradicts what is said in the summary and TFA. In fact it seems like the author of TFA is illiterate and can't understand clear, simple English statements.

    I have watched a ton of documentaries and presentations by scientist, grid specialists and people from the energy industry and they all agree that you can replace between 70 and 80% of your energy generation with renewables. A lot of the renewable energy generation will take place in very close proximity to the consumers. This will take the form of wind generator parks, solar generation parks and a considerable amount of renewable energy generation will probably take place on the roof of the consumer's house or in their back yard with a corresponding reduction in the need for grid infrastructure. Throw in some storage, 20 to 30% always-on power generation (nuclear/gas + carbon capture), smart grid technology, maybe even super conductors, cutting edge computer model aided planning of wind/solar park location and a generally modernised grid and you have the future of energy production. The Germans aim for 80% replacement with their 'Energiewende' move to renewables but they also factor in a certain amount of always-on power-plants. This is what the experts say and it is also what that abstract is basically saying as well. Now did anybody expect a bunch of German engineers to decide you can cover the vast majority of your energy needs with renewables without first doing the math on the problem first? The idea of going for 100% renewables is not viable, it never has been, you will always need some always-on power-plants in your mix. Focusing on the 100% renewables case when the one everybody is aiming for is the 70 to 80% case is simply a cheap attempt to find material for some good old fashioned FUD that can double as clickbait.

  3. It's irrational rationality. Running an unsafe nuclear power plant because you don't like paying taxes and don't trust the government is irrational. But if you've already accepted that level of irrationality then the next rational thing to do is not run the plant in the first place.

    If I understand what you're saying, you're suggesting that nuclear power plants will be privatized, and therefore unsafe? Maybe you are suggesting this because of what happened with Fukushima?

    The thing is, a majority of nuclear power plants in the U.S. are already privatized (but heavily regulated). That exact arrangement has provided the extraordinary safety record that we observe from nuclear energy. Why would you think things would be any different in the future? There's no movement I'm aware of to abandon those proven safety regulations, and so the most reasonable expectation is that nuclear energy will continue to demonstrate the same, exceptional level of safety and reliability that it always has.

    Why would we think things would be any different in the future? Because whenever the damn Republicans start handing out deregulation cool-aid it has a tendency to end badly. It just plain scares me to think of what may happen if the Republican deregulation brigade ever ever decides to aggressively deregulate the energy industry with the usual set of dumb ideas like: "you can't pass a new a regulation unless you abolish three old ones", and then decide this should apply to nuclear safety regulations as well because the nuclear safety regulations are a totally unnecessary bureaucratic abomination that only 'stifle the economy and hinder growth'.

  4. No one's disagreeing with you there. But this hardware is being sold like an "appliance" and it isn't failing as an appliance - it's being effectively remotely disabled.

    There are DVD players still going strong after 20 years of use. VCRs still kicking after 30. AM/FM Radios still going after 50+ years. There is still no question that the obsolescence was built into the Apple TV by virtue of how it is designed and what it's required to rely on. And in the end, you're still effectively renting the hardware - but it's being treated for most legal purposes like a purchase.

    Products get obsoleted, it's a fact of life and I somehow doubt that your Google, Amazon, etc. streaming boxes will still be going strong and getting steady updates in 50+ years so any 1st gen Apple TV owners probably haven't been screwed any worse by Apple than if they had done business with most other streaming box manufacturers 11 years ago. Would I like to wring a few more than 11 years out of my 4th gen Apple TV? Sure, but I somehow suspect the games I like to play will no longer be playable on that thing in 11 years, it will be starting to show all kinds of other signs of age and I will have saved up for a new one by then. Having said that, and assuming you are the kind of person who'd even buy an Apple TV (which I doubt), if you really want to keep using your 1st gen. Apple TV there are plenty of media centre packages available and none of them looks terribly complicated to install. You can even choose from among several smartphone remote apps. This is something I could see myself doing to my 4th gen Apple TV in 10 years if I decide to I go out and buy a dedicated gaming console instead of an Apple TV but we'll see. Ten years is a long time.

  5. Re:$100 million for 2490 classrooms? on Tesla Deploys Over 300 Powerwalls To Give Hawaiian School Kids AC (electrek.co) · · Score: 3, Insightful

    School happens primarily during the day. Heat is primarily a problem when the sun is shining brightest. The schools already have an electrical connection to the grid.

    Explain again why they needed power-wall batteries for each installation instead of just using the solar power directly when it was needed the most (on hot, sunny days, which generate the most solar power) and relying on a little bit of to/from grid action at other times if necessary?

    This sounds an awful lot like a publicity stunt, i.e. kids + batteries + renewable science, now everyone sing kumbaya!!!

    Silly questions but I'll try to answer it in a factual manner. On the Hawaiian archipelago they generate anywhere from 60-75% of their electrical energy (depending on which island you are on) with oil of all things. That and the fact that Hawaii is located in an area where solar panels should be quite efficient should result in there being a a good chance that the energy from the solar installation is considerably cheaper than the mains energy (In 2016, Hawaii actually had the highest electricity prices in the entire USA) so why not maximise the use of every spark of solar energy you can harvest even during periods of low sunlight? ... or should they be maximising the use of oil generated electricity and then sitting around a a big pile of extortionate electrical bills singing jolly songs in praise of the oil companies? If I was a Hawaiian I'd dimension my solar panel installation and battery pack in such a way that I'd never have to tap the grid for a single kilowatt all year round, the next thing I'd do after that would be to buy an electric car.

    Right wing? Check. Fundamentalist Christian? Most definitely. But fascist? Citation please.

    I'm not a fan of Pence either and I disagree with the GP too. I see the difference between Pence and Trump mostly as being that while Pence is a stuffy conservative Bible thumper at least he is a rational, intelligent and an experienced politician whereas Trump really is just a couple of steps down the skill ladder from an organ grinder's monkey. Pence could, for example, be trusted **not to start a nuclear exchange** with North Korea with a stream of late night rage tweets while sitting on the toilet bowel-moving three Big Macs, he could be trusted to stop the systematic disassembly of the state department since even the Pentagon is on record calling the ongoing state department massacre a huge mistake and he would probably go on a world tour repairing the damage Trump has done to America's network of allies which is pretty much the basis of America's power. For the Chinese the Trump administration is a godsend, I just heard an Asian diplomat describe the situation at various important political and economic events over there. What he said was that while the US downsizes its diplomatic corps and shows up with two guys at various international events in Asia, the Chinese show up with several dozen. Now who do you think is having more influence there? The two guys Rex Tillerson deemed it worth while to send (Starve the beast!! Starve the beast!!!) or the four dozen guys that Beijing sent? The difference between the Pence administration and the Trump administration would be minimal in terms of the odiousness of their policies, the big differences/improvements of a Pence admin. would be that (a) the US would have a stable force governing it, a group of people with something resembling a plan, that commands some kind of respect abroad (b) the systematic disassembly of the US's power base would stop and (c) the USA would cease being the biggest laughing stock on this planet.

    You ask me this feature would be a big relief. It is such enormous fun to be made to jump through all the flaming interview hoops only to find out that you are expected to work for a totally unacceptable salary. However, there are other tricks that employers use like offering a flat salary while they retain the option to make you work over time and weekends whenever they want to. At this one place I applied for a job they asked me how well I worked under pressure, I told them I'd finished a Comp Sci degree in the top ten percent of my year, what did they think? Then I asked the HR type: Why do you ask? Will I be spending a lot of time working under pressure? He was not amused. So just some hints for those of you who are just starting out:

    1) If they want you to work for a flat salary with no ceiling on working time and promise it will only be the occasional evening and weekend work only in emergencies that is HR speak for: "We are planning to put you on permanent 24/7 standby without paying you extra for it."
    2) If anybody ever asks you during a job interview if you work well under pressure that is HR speak for: "We are running our company's operations with a skeleton crew to maximise profits, we are always on the verge of missing deadlines and you can expect to be worked to death"

    Also watch out for clauses in the contract that prohibit you from working for anybody else in the industry for N years after quitting at their company. Some employers even add clauses forbidding you to work on any FOSS projects at all. That is bad because FOSS projects are a good way to satisfy the kind of employer that wants you to provide code samples. I'm fine with code samples but I usually don't waste my time on perspective employers who send me math puzzles since I have yet to be offered a job solving math puzzles. One outfit I worked for even tried to get me to sign a new contract that contained a clause so broadly worded that they could have claimed ownership of *any* code I wrote, even on my own time outside of working hours and even if it was unrelated to their business. I'm not going to attribute malice to this, that contract was probably just written by a really incompetent lawyer whose chief qualification was being related to one of the managers but I still refused to sign the damn thing. Now if Linked-in would add a feature that allows me to see shit like this it would make my life even easier than knowing in advance what they are planning to pay me.

Secondly the specification for an exact Bob replacement was so insanely specific it could only have been met if they'd had a backup tape of Bob's brain and then uploaded it into a Bob clone they commissioned from some underground cloning facility in North Korea. The lesson I drew from these experiences is that most employment agencies, head hunters and HR people (with a few notable exceptions) are largely useless in this capacity. I've been interviewed by exactly one HR person who I thought did a really competent job. Other than that the only truly useful job interviews I have had were with the department heads and people I would be working for/with.
