    Since you mentioned Superchargers I assume you are specifically talking about Tesla's EVs
    In a Tesla you don't stop for 30 minutes every 100 miles. You start the day with 300+ miles of range and drive for 3-4 hours. Then you stop for lunch. Superchargers are very widespread, and almost always are next to food., A 30 minute stop adds 200+ miles of range, so you can drive another 2-3 hours.
    So there's your 500 mile round mile trip. One stop. You did stop somewhere along the way right? Otherwise why did you make the trip?
    And although there is only one place with the newest V3 supercharger, they will be rolling out, and they reduce the charge time for 200 miles to 15 minutes.

    Heat lags peak solar by several hours. Hawaii's grid can't absorb the excess generated at nonn, and strains to supply the need as consumption ramps up just as solar is starting to fall. Some storage to time shift the produced solar power by a few hours is pretty much mandatory, once solar starts to be a large fraction of the total supply. You also need the storage to smooth out sudden dips likes a storm blowing in. Solar production can drop by 80% in a fraction of an hour. That's not a problem if solar is only a few percent of your energy mix, but it can lead to grid instability if the solar is meeting nearly 100% of the total demand at noon, and the conventional power plant is idling near zero output. Fossil fuel plants take time to ramp up. Battery storage (or other grid scale storage) is mandatory for a stable supply once solar (or solar and wind) become a large percentage of total supply.

  8. As soon as someone mentions "hydrogen energy" I know they can be dismissed as uninformed. Hydrogen is a lousy, inefficient way to store or transport energy. The reasons are so numerous and fundamentally intractable that anyone who thinks hydrogen will be an economical way to power anything on a mass scale has to be lacking in basic science and engineering knowledge. Hydrogen will have niche uses, but is very unlikely to be the fuel of choice for cars.

    But in about 18 - 24 months we will have a definitive answer as to whether or not "actual consumers would voluntarily pay the true cost of these vehicles." Tesla will soon cross the threshold of production volume where the subsidies on their cars phases out. Most of the 330K+ people who have put down deposits to get a Model III will be getting that car after the subsidies end. Or they will cancel. Time will tell.

    The article implies that they plan was to make functional devices with enough explosives to be dangerous. I suppose you could make a false back for an iPad that increased the thickness by 2-3 mm and had enough oomph to blow out a window. But there a million other ways to smuggle in bits of explosive. It wouldn't take any high tech machinery to candy coat a bunch of plastic explosive and make it look like a one pound pack of M&Ms. The ban is stupid.

  19. From the LA Times"
    What about people in the country illegally who are able to obtain driver's licenses in California under a law passed in 2013?
    Padilla noted that there is already a separate process for residents in the country illegally to apply for special licenses. Although citizens are currently offered the opportunity to register to vote at the DMV under an earlier federal law, noncitizens are not. That will continue under the new registration process. People applying for the special licenses will not be asked about their eligibility to vote and will not be asked if they’d like to opt out of registration.

    “We’ve built the protocols and the firewalls to not register people that aren’t eligible,” Padilla said. “We’re going to keep those firewalls in place."

    So merely getting a special CA drivers license does not facilitate illegal voting. And people here who shouldn't be, and who are subject to deportation are in any case unlikely to stick their head up and ask for it by voting when they shouldn't.

  20. The rules of the election are set by the US constitution, which gives electors complete freedom to vote any way they want. Federalist paper 68, the one that discusses the role of the electors, specifically states the electors have a charge to overrule the popular vote if they have been duped:

    From Wikipedia -"Hamilton focuses on a few arguments dealing with the use of the Electoral College instead of direct election. First, in explaining the role of the general populace in the election of the president, Hamilton argues that the, "sense of the people", through the election of the electors to the Electoral College, should be a part of the process. The final say, however, lies with the electors, who Hamilton notes are,

    "Men most capable of analyzing the qualities adapted to the station and acting under circumstances favorable to deliberation, and to a judicious combination of all the reasons and inducements which were proper to govern their choice."

    Therefore, the direct election of the president is left up to those who have been selected by the voters to become the electors. This indirect election is justified by Hamilton because while a republic is still served, the system allows for only a certain type of person to be elected president, preventing individuals who are unfit for a variety of reasons to be in the position of chief executive of the country.

    This is reflected in his later fears about the types of people who could potentially become president. He worries that corrupted individuals could, particularly those who are either more directly associated with a foreign state, or individuals who do not have the capacity to run the country. The former is covered by Article II, Section 1, v of the United States Constitution, while the latter is covered by Hamilton in Federalist 68, where he notes that the person who will become president will have to be a person who possesses the faculties necessary to be a president, stating that,

    "Talents for low intrigue, and the little arts of popularity, may alone suffice to elevate a man to the first honors in a single State; but it will require other talents, and a different kind of merit, to establish him in the esteem and confidence of the whole Union, or of so considerable a portion of it as would be necessary to make him a successful candidate for the distinguished office of President of the United States"

  22. It is a capacitor. That means the voltage is directly proportional to the charge. That doesn't make it useless, but to extract most of the stored energy you need a load that can work over a 5:1 or more voltage range. (at 20% of peak voltage you have extracted 96% of the energy because the store power is proportional to the square of the voltage.) A Tesla battery pack can supply more than 1500 amps at 300 or more volts even when it is at 100% charge, and almost just as much current, at almost the same voltage, when it is at 10% or less of full charge. A giant supercapacitor that was designed as a replacement, might, just for example, have a full charge voltage of 600 volts, and be designed to work down to 120 volts, and would have to supply, in this scenario, 750 amps at 600 volts, increasing to 3,750 amps at 60 volts to deliver constant power. A challenge to the power control circuits indeed.

  25. There is a large and very consequential difference between a 30 minute stop and a 4 hour stop. My wife has a Tesla S80, and a lunch stop at a supercharger station halfway towards Reno from the SF bay area makes the trip easy. The stop is usually more like 40 minutes, and that gets the car pretty full. If it took 4 hours to do the same, we'd take our ICE vehicle instead.
