  1. Re:Why not a solar roof over the road? on China Is Building a Solar Power Highway (electrek.co) · · Score: 2

    I absolutely do not understand why anyone would consider embedding solar panels underneath clear concrete[1] for a road.

    I'm not an engineer but wouldn't the weight and/or vibrations from cars and trucks, over time, possibly mess up the electrical connections or the panels themselves?

    I don't know but It sure is nice that somebody is ready to build something like this and find out. This is not the first project like this, there is 1km stretch of solar road in Tourouvre-au-Perche that powers the village's entire grid of street lights. Meanwhile Trump is working hard to take America back to good'ole patriotic coal, oil and gas (cue patriotic music and warm fuzzy patriotic feelings). Renewable energy companies in N-Europe, Germany and China are celebrating Trump as a bonus period of 4-8 years in which to leave the United States behind in renewables research and development. The best part is that US conservatives are still harping on about how gas is way cheaper than solar repeating the old mantra about how China is not taking responsibility and that the US won't do so until China does and yet the Chinese and the Germans/Britons/Dutch/Scandinavians combined are plowing well over a trillion dollars into renewables over the next two decades.

  2. +1 for mentioning HEMA. It's a great sport and my brother is very good at it. Is it European only?

    I haven't been doing HEMA long but there is a lively community in the US, Canada and down to S-America judging by the people I ran into at the last newbie course I attended. Japanese fencing does not really come under HEMA since it is European only but many people who go to these events come there from Kendo or from Olympic saber fencing like I did but it is still fun to mix things up and see what happens, like Rapier vs. Katana or Walpurgis sword and buckler vs. Katana (or even arming sword and full sized shield vs Katana or Katana and Wakizashi) which is another thing I'd like to seen in Star Wars, force-field shields and bucklers there is no reason for not having hand held shield generators if you can fit enough energy to contain a plasma stream in a sword hilt.

    Hell they didn't even get the name for the stupid light_sabers_ right? Sabers are _curved_, that's what differentiates them from a sword.

    Firstly, sabers are swords just like a Ferrari is a car. Secondly, while the saber started out as a curved bladed adopted by Europeans through contact with the Ottomans, by the 19th and early 20th century sabers became progressively more straight bladed. The US Model 1913 Cavalry saber for example, had a completely straight blade as did many other contemporary sabers. but you are right in that the 'light saber' has nothing in common with any kind of saber. If the lightsaber is anything it's a kind of 'laser shikomizue' or something (one of the few straight bladed Japanese swords I can think of other than a Shinobigatana). Kylo Ren's weapon is more of a 'laser longsword' and he uses it a bit like one too. That was kind of interesting to watch because the 'light sabers' in Star Wars are used in a somewhat 'katana-esque' manner and it is always fun to see Talhoffer and Liechtenauer's ideas clash with the Japanese mindset. Mind you it's way more fun to watch at a HEMA event where the Longswordsman and the Katanna fanboy are both purists and both of them actually know precisely what they are doing.

  4. "Subsidies for renewables, which far exceed those of fossil fuels, are used to make them appear cost effective."

    No, they are used so that people will have an incentive to adopt renewables, thus creating an economy of scale whereas renewables become commonplace. It's not just "for looks"

    That statement should be in the past tense. Fossil fuel extraction costs are an upward trending proposition because of increasing extraction costs. Once in a while you get dips like you got with the shale bubble but on the whole the trend is upward. The price of renewable energy technology is on on a downward trend due to economy of scale, you don't have do drill through the earth's crust or dig away mountains to get sun and wind. We are now at a place where renewables are getting cheaper than coal and gas without subsidies. With battery technology undergoing an economy of scale and engineering revolution things do not look good for fossil fuels. Anybody buying a coal or gas fired power plant these days is being sold a pup.

    To be fair "these days" was referring to 2011, when that article by Sanders was written. A time when the Venezuelan economy was rebounding. Two years before Maduro was even sworn in.

    To be really fair, when someone predicts something and their prediction turns out accurate, then their hypothesis is *probably* correct.

    Like if, for example, someone in 2011 said "Socialist policies don't really work, mostly", and Sanders points to Venezuela as an argument that they do indeed work, the future collapse of Venezuela provides support for the statement "Socialist policies don't really work, mostly", not for whatever counter-argument Sanders was attempting to make.

    Another example to clarify: if I were to say, right now, that BTC is not really a currency and you point to its use by $fraction of retailers as proof that it is a currency, any future decline in BTC acceptance by retailers adds support for my assertion, not for your counter-argument. A future rise in % BTC acceptance by retailers may provide the support for your counter-argument, but current cherry-picked examples do not.

    Predictive power beats single-data-point examples when proving or disproving a hypothesis. Pointing to a single example only works when the assertion is an existentialist one ("All $FOO are unworkable" needs only a single counter-example to disprove, while "$FOO is not long-term viable" cannot be disproved with a single counter-example).

    The FUBAR otherwise known as the Venezuelan economy is what happens when you over-leverage your economy and bet on oil prices permanently remaining at an all time high. Conflating Bernie's brand of social democracy with Chavista style socialism and then pointing at Vesezuela as an example that Bernie's ideas don't work is simplistic to say the least.

    Bollocks, republic and democracy are not mutually exclusive things. The USA is a democratic republic, or more specifically a federal republic with features of a representative democracy where where elected individuals represent the citizen body in government. If you require further proof read the writings of the founding fathers, the federalist papers and a whole mountain of other literature on the subject although most of us don't need to do more than note the fact that every two years you guys go out and directly elect congress critters and senators that are supposed to represent you in the US congress. Furthermore every four years you also directly elect a bunch of people that in turn elect a president on your behalf. That last bit is a quite strange arrangement to be sure but most of the rest of your process of choosing your leaders makes the US a republic with a form of representative democracy even if it has some esoteric features. What the US isn't is a pure direct democracy but then very few countries practice pure direct democracy except maybe certain parts of Switzerland where all the oath brothers and oath sisters (aka. the citizenry) assemble in public places all over each canton (since even the Appenzellers have finally been dragged kicking and screaming into the modern age and now allow women to vote) and the entire citizenry then votes on legislation without any representatives acting as intermediaries. Obviously such a system would have been rather hard to coordinate in the US of the 18th century so, unsurprisingly, the founding fathers of your country went the representative way. The problem the USA has, like many other countries with representative democratic systems, is that not only have your democratically elected representatives come to believe that they are elected by you, the people, to serve the interests of the oligarchs who stuff their pockets full of money, they have convinced large portions of the electorate of this as well. In my estimation and that of many Americans this is a process that is in dire need of begin reversed and Ajit Pai is just one living breathing and smugly grinning example of why.

    Yeah, they have been doing some really shady shit.

    . . . the major problem with the FCC’s move: It forced ISPs into an 80-year-old framework designed for the telephone monopolies of a much different era. Those regulations were more concerned about things like controlling market power than, say, promoting innovation.

    Except this is exactly the issue we are worried about. How is it a much different era? Did companies stop being greedy? Did they stop consolidating to control massive swaths of customers? How is this era any different?

    I don't think companies stopped being greedy. What is different is that the idea the internet should be a level playing field has breathed it's last breath because Google, Facebook, Twitter, Apple, Hulu, Netflix, Amazon, and the rest of the big players who used to fight for net neutrality realised they can afford to pay the extortionists their pound of flesh, that given the utterly corrupt nature of the Trump administration they have to and finally that the real threat is not the extortionists, it is scrappy startups with a better business model and product than them. These startups will from now on be competing at an even greater disadvantage because people have now accepted that is both normal and desirable for the extortionists to ensure that the bandwidth of smaller players is limited and their customer's connections are regularly interrupted by 'technical problems' unless they pay a ransom. The death of net neutrality will work to the advantage of both the extortionists who will now get their regular infusion of mafia style protection payments and the established big players. So in future expect any upcoming competitor who threatens somebody like Google for example and starts to chew up their dominant market share to die a death of a million connection error messages because Google felt threatened and and crapppified their service by pulling the protection money strings so that Google can eventually buy up the corpse and its patents and technology with it. Just ask Eric Schmidt, he'll be the first to tell you how proud he is to call this: "capitalism working as intended" (... and to hell with Adam Smith).

It was Iranian, American and even European backed forces that did just as much if not more to destroy ISIS in Iraq and the same goes for large parts of Syria. It was US/German/French training and delivery of Milan missiles along with US and Iranian small arms and ammo deliveries that stopped ISIS from overrunning the entire north of Iraq while the Iraqi national army that Nouri al-Maliki purged of any soldiers who knew what they were doing was still trying to figure out which end of their rifles was the one the bullets come out of, and lets not forget the importance of US/NATO and even Iranian air support either.

    A wind farm with 100 turbines would produce about 2-4 GW of power depending on the type of turbine. Larger wind farms are usually smaller than that. They consists of turbines in the 1.-4 Mw range but I have seen bigger ones. A wind farm of 2 MW producing 200 MW occupies an area of about 12 x 12 km. But building nothing but big wind farms is not what normally happens. What they are doing in Germany and Denmark for example is mixing together large wind farms with small clusters of them, dotted over the landscape and supplementing that with rooftop solar installations and batteries. Many farms in Northern Germany for example have wind turbines in the fields and every roof of every building and rain shelter on the farm is completely covered with solar panels. Same for the surrounding towns and villages. Apartment blocks in cities often also have their roof covered in solar panels and you are now seeing wind turbines even inside cities.

    As for carbon footprint. A wind turbine represents a fairly large carbon footprint during manufacture and after that a minimal carbon footprint during decades of maintenance and operation. A coal plant represents not only a large carbon footprint during construction but also a large and steady carbon footprint during decades of operational use and it also generated other forms of pollution like for example sulphur dioxide. Gas plants also represent an enormous carbon footprint in construction and especially over their lifespan. The idea that a wind farm over 30 years of operation is going to match the carbon footprint of an equivalent (in power output) coal plant or even a gas power plant is quite frankly laughable. All studies I have seen show an order of magnitude lower carbon footprint (kg of CO2 per KWh) for solar and wind compared to coal, gas and biomass and it is usually wind that has the lowest footprint at about 1/4th the footprint of solar which itself has about 1/20th the footprint of coal/gas.

The fossil fuel pundits never count the cost of the enormous carbon footprint of coal/oil/gas and the cost of the damage that carbon footprint does.

The basic truth is that coal/oil/gas are wreaking havoc in the life support system of this planet (hint: the part of your environment that produces oxygen for you to breathe) that makes them a liability, economically, environmentally and even in the USA they will eventually become a liability politically. Coal/oil/gas is already a political liability in much of the rest of the world.
