  1. 75% of Duke's generation mix is coal or natural gas. So, rather than offset any of that base load with a 2.2 GW nuclear facility, they'll supplement demand growth and cover peaks with solar and keep burning the coal and gas. It's cheaper and they get to wave the green flag etc.

    Gas right now is so cheap and you can get 10 year contracts so it is killing any other generating source economically.

    Power sources should really be categorized in one of three classes: 1. Flexible on-demand (natural gas, hydro, battery storage); 2. Base load (nuclear, coal); 3. Uncontrolled generation power (wind, solar).

    They already are: Baseload - plants that you run full bore 24x7 Mid - cover the fluctuations between base and below peak Peakers - plants that can come online quickly to satisfy demand during peak hours.

  3. all the utilities has to do is install batteries for incoming solar generated power, simpler and faster to bring that online when needed.

    And then charge those selling power back to the utility for the capital and O&M costs of the batteries; rather than charge all consumers so a few can sell power.

    Tax breaks mean that the public costs involved in starting up that new plant have to be borne by other taxpayers, other companies.

    You may not care about the free market, but this is a case of the government picking winners and losers.

    Exactly, and for government the most important things is the winners are the incumbent politicians the next time tehy are up for election. Thus, all the "We created X jobs..." when all they really did was throw a bunch of money at a company that was going to build somewhere, and may leave when a better offer comes around.

  12. The "break even" in TFA is only based on tax revenue. Governments don't exist to collect taxes, they exist to serve the people. If you look at the overall gain in secondary business and employment the break even is way sooner than two decades.

    A lot depends on how many people they actually employ and where they live. If the live across the border much of that money will wind up there. While it s true that secondary economic effects will reduce the payback time the tax breaks will be a, if not the, most significant impact on the return.

    None the less, these tax breaks are really just a prisoner's dilemma. State offer them because other states offer them, but they would all be better off if no one offered them, and factories were optimally placed based on other factors. We would likely all be better off if there was a federal law to ban this nonsense.

    I agree that it is just a race to the bottom for localities. However, there will never be a Federal law because Congress likes to play the same game by brining in "directed spending" (i.e. pork barrel spending) to encourage companies to locate somewhere and bring in jobs. That doesn't create jobs all it does is pick winners and losers.

It might not be accurate enough closer to shore but in deep water it should be serviceable until GPS is restored.

    Until we develop a way to block, or spoof, the sun and the stars there is a reliable and accurate backup for navigation. You need a precise time piece, sextant, nautical almanac, and charts along with a mariner who knows how to shoot the stars. The Nav on a frigate I was on did a daily celestial fix to double check our position with the radio fix. he could get a set of readings very quickly so the line of position produced a very tiny box for our fix. I'd bet my life on his fix before the radio fix.

    The downside is you need to be trained and practice to keep sharp. I used to be good at it but couldn't get a fix to save my life now. With computers you could input the readings and get it to give you lat/long so there is no need to draw LOP on a paper chart. In a pinch you could send that out as you position.

  15. For example any driver who dropped off and came back when surge pricing started could simply not be given ride opportunities until the surge ended.

    Another way of looking at this is that some of the drivers are unwilling to drive when fares are at "normal" price but figure it is worth it when surge pricing is available. Perhaps there is not even collusion in this and Uber is spinning it as collusion to introduce new rules...

    But then, if those drivers were not willing to drive without surge pricing, changing the rules will not make them more willing to drive when fares are low.

    Possibly, but the drivers in TFA basically said they are colluding to drive up fares. It is in Uber's interest to stop such behavior; which is different from drivers individually, at varying times, decide not to drive.

    we wouldn't be having this conversation. The drivers would have stopped doing this when they saw it didn't work. It worked because most Uber drivers also drive for Lyft since neither company pays enough to make it to your next rent payment.

    While it may work short term I doubt it is sustainable long term strategy, at best it will work in areas with few drivers who can maintain the agreement. Otherwise, drivers who don't sign off to drive up pricing will get the higher fares; which increases the pressure on drivers to either not collude or jump back in before the others do. In addition, Uber can adapt it's software to identify such actions and make them unprofitable. As for transparency, as people learn that Google offers fare comparison as well as booking from maps; gaming the system will simply drive down demand as riders chose the other service or, as a link in TFA says, rides will learn to simply wait a few minutes until the surge passes. I've done that and seen prices drop to a third of the surge price in minutes. Can the drivers pan work? In localized areas probably for a while, is it scalable, no.

    Sorry braw, but the free market fails here. That's why we regulated cab companies in the first place.

    While cab regulation has benefits for the rider such as vehicle and driver safety requirements, fixed fares, etc it also benefits drivers and owners by limiting competition by controlling the number of licenses, does not ensure your driver will pad the fare by taking a longer route (scubas often happens in Ls Vegas on trips to the airport), and sometime results in monopoly franchises at high traffic areas.

    Should Uber be regulated more? Sure, but brah, regulation is not a panacea either.

    Yup. People learn how to use the system to their advantage. One problem with this sytem is Google. If you set a destination and get directions under hire it will show Lyft and Uber fares so if ine has surge and not the other guess who will get the business? Fare transparency overcomes collusion in this case. Unless most drivers drive for both and do this in both cases it is not a good long term strategy. In addition, Uber and Lyft could monitor the drivers and penalize collusive behavior. For example any driver who dropped off and came back when surge pricing started could simply not be given ride opportunities until the surge ended. Thus drivers who didn't game the system would get the benefits while those who do lose money from their collusion.

    an EPIRB doesn't summon the boat half a mile away from you to come and help. EPIRBs are a godsend offshore, or in truly isolated areas, but they're not a substitute for making that call over the radio. On the water, everyone be they coastguard or not, is expected to respond to a distress call if feasible and safe to do so. One of the "good" things about being a slow sailboat is that we're rarely in a position to respond, but over the years I've done so twice. In one case, it was to bring in a disabled runabout that was lost in a fog bank with a disabled engine (we just happened onto him), and the other was picking up a kite surfer who was stranded a mile offshore with his lines all in tangles and kite under water.

    Basically, it's not just the coast guard who responds, but any available boat or mariner. If I ever wind up in trouble, I hope that someone else will come and give me a hand.

    All good points, and certainly any mariner should respond to a distress call; and I agree there is no substitute for voice calls. Auto beacons are great as set and forget tools but as you and others point out they are a one way communication.
