Tesla Tuesday

TempPics 001

Stationary coils with a neodymium magnet filled rotor when assembled together makes a very strong motor/generator.

Tesla’s shift to a magnetic motor using neodymium in its Model 3 Long Range car adds to pressure on already strained supplies of a rare earth metal that had for years been shunned because of an export ban by top producer China.

Efforts by governments around the world to cut noxious emissions produced by fossil fuel-powered cars is driving demand for electric vehicles and the metals used to make them, such as lithium and cobalt which are key ingredients for batteries.

Now the spotlight is on neodymium. Several auto makers already use permanent magnet motors that rely on the metal because they are generally lighter, stronger and more efficient than induction motors that are based on copper coils.

But it is the switch to neodymium by Tesla, an auto maker that has staked its future solely on the electric vehicle, that is showing the way the industry is moving and the direction of demand for the rare earth metal.

    Well…another day of chaos.

    We can speculate until the cows come home, but we will probably never know the specific reasons Trump ousted Secretary Tillerson.

    Both men are inexperienced in diplomacy, but I believe it’s fair to say, that Tillerson has better skills in that department than our shoot-from-the-lip president.

    Tillerson and Trump disagreed on very important policies: the Secretary of State preferred dialogue on the North Korean nuclear crisis; he wanted the U.S. to remain in the Paris climate accord; supported the Iran nuclear deal. Trump was against him on all of those policy positions.

    Tillerson, a one-time head of the Boy Scouts of America, was aghast when Trump would not denounce white nationalism at a BSA gathering that the president turned into a political event.

    Tillerson never had a chance in this White House. I give him credit for sticking around as long as he did.

    Yea and Pompuseo is his replacement, yikes!

    The are rare earth concentrations, mineable as ores when the price is high enough, in Australia and in Nevada or Utah, I forget which.


    • David B. Benson says:

      Probably both Nevada and Utah. For years Reed and Hatch would introduce in the Senate an act requiring the DoE to buy the mine tailings from such mines. The tailings are the best source of thorium so there was a justification. But the bills never progressed although somehow the DoE has several hundred thousand tons of such tailings at the Nevada Proving Grounds.

      And locally, maybe we are going to have a bit of sun.

        The show Timeless got me to read the wiki page of Marie Skłodowska Curie. Fascinating person, did not know she was a Polish citizen by birth.


        • §º¿º§ Carol says:

          Since my dad was Polish, I’ve always known Curie was Polish. My father-in-law was Hungarian so I always knew of everyone who was Hungarian. Joe Namath, for instance, and he changed the spelling of his Hungarian name from Nemeth to Namath.


        • §º¿º§ Carol says:

          I can’t watch Timeless until I have two recorded. My Bob is going to miss the new season. 😦 Missing the new season of a lot of things.

    Once again 65 minutes to go up to the TVD bridge and back to the Old Post Office. Some roosting pigeons and flying magpies this grey day.


    • David B. Benson says:

      A total of 94 minutes today. Away to the southwest rain is falling from clouds but evaporating before it is half way to the ground.

      Day 3: 145+94=239 minutes.


  5. §º¿º§ Carol says:

    Had my 4 week check up on my left eye, all is good, my retina is still attached. The doctor wants to see me again in a year.

    The good news is if the retina detaches, they can fix it so I’m really happy I decided to take my eye in 4 weeks ago. It was funny, Pete and Jill were here when I told them about my eye and the flashes of light I was seeing, they insisted I call right then for an appointment and damn if the office didn’t tell me to get my butt over there right away. Instant appointment.

    I ordered the two DNA kits from Ancestry.com! One for me and the other one they are mailing to Bob’s brother. Barbara called me yesterday and I talked to Steve and asked him if he would do the test, and he said “sure.” WOO HOO! The tests are going to find out that Bob and I are as white as they come. European white. My grandparents came from Poland and Lithuania which was Russia, I think. And Bob’s grandparents came from Hungary.

    Poured rain all day here

    Big solar storm coming, Den.


  9. Den says:

    This is a “coronal hole”–a region where the sun’s magnetic field opens up and allows solar wind to escape. Coronal holes appear, in various shapes and forms, several times each month. This one is unusually wide, stretching more than 800,000 km across the face of the sun.

    And that ain’t all!

    A newly discovered asteroid designated 2018 EZ2 will flyby Earth at a distance of 0.56 LD / 0.00144 AU (~215 420 km / 133 856 miles) on March 14, 2018. LINK
