• ZipDialog Roundup for Tuesday, August 1

    Articles chosen with care. Your comments welcomed. Linked articles in bold purple

     Comment: What the Scaramucci ouster shows:

    • The initial appointment was another of Trump’s unforced errors
    • John Kelly has quickly asserted control over White House staff, obviously with Pres. Trump’s blessing
    • The White House desperately needs to assemble a stable, competent communications team (Rumors are that Kellyanne Conway could be the new Communications Director; she would be a good choice.)

    ⇒ More at a separate ZipDialog post here.

    If anybody can run this circus, it’s Kelly. The biggest question is whether he can get the Ringmaster to restrain himself. Conway did it for several months as campaign manager. Perhaps Conway and Kelly can do it again. But they are facing an impulsive, temperamental, thin-skinned boss.

     More night-time lights in North Korea show an improving economy, despite sanctions  (Fox)

    Comment: Blame China. They’ve played the US for years. Trump, James Mattis, Nikki Haley, and Mike Pence have all declared that the time for talk–and waiting for China’s voluntary assistance–is over. Easier to say than to do.

    The question is whether any pressure on North Korea, either directly or via China, will stop them? China will only act if they fear a dreadful alternative. The only possible alternative short of war that they might fear is a nuclear-armed Japan. Moving in that direction is obviously fraught with dangers.  Before that, expect more anti-missile batteries, possible shoot-downs of North Korean launches, and economic sanctions against Chinese banks and trading companies.

     Pres. Trump himself dictated Jr’s misleading statement about meeting with Russian lawyer  (Washington Post)

    Comment: It’s hard to be stunned by this White House–or the leaks–but this qualifies. It is almost certainly not obstruction of justice in its own right, but it will undoubtedly attract the interest of Special Council Robert Mueller, who will look for a pattern.

     Venezuela sinking into a chaotic dictatorship, with economy in free fall  (Washington Post)

    Comment: The US is imposing more sanctions and could impose even more stringent ones. If so, expect the Iranians, Russians, and Chinese to step up and offer support in bids for more influence. The Iranians already have big-time connections there, forged under Chavez.

     Alabama inmates escaped using peanut butter. In jam after capture.  (Washington Post)

    They used peanut butter to renumber the jail cells and fool an inexperienced guard.

     Alphabet (Google) working on new way to store lots of energy; alternative to lithium-ion batteries (Bloomberg)

    They have a “skunk works” operation that tries to develop these long-shot projects. The idea here is to send energy to a heat pump, some of which will supercool antifreeze (or some alternative liquid), some of which will heat molten salt. When air from the separate hot and cold tanks are combined, they produce wind vortexes that spin turbines and generate electricity.

    Alphabet is working with prototype plants now and could be ready to work with a manufacturer soon to build a real-world version. The plants could range in size from as small as a garage to as large as a conventional electric plant.

    Besides scaling up, the researchers are looking for ways to build the plan with cheaper materials.

    Storage like this is crucial if renewable energy sources are to play a larger role since most renewables only produce power intermittently (when the sun is shining, the winds are blowing, etc.).
