oh ffs.

for starters, killing our magnetic field, removing the protection we enjoy from solar radiation that also keeps our atmosphere from blowing away in the solar wind. There wouldn't be anybody left to enjoy the irony of actually destroying our planet while trying not to make it too warm.

An eight-car pile-up on Nov. 24, 2022, on San Francisco’s Bay Bridge. Photo: California Highway Patrol highway surveillance footage from Thanksgiving Day shows a Tesla Model S vehicle changing lanes and then abruptly braking in the far-left lane of the San Francisco Bay Bridge, resulting in an eight-vehicle crash. The crash injured nine people, including a 2-year-old child, and blocked traffic on the bridge for over an hour....The driver told police that he had been using Tesla’s new “Full Self-Driving” feature, the report notes, before the Tesla’s “left signal activated” and its “brakes activated,” and it moved into the left lane, “slowing to a stop directly in [the second vehicle’s] path of travel.”

If you like listening to talk, checkout the Joe Rogan Experience on Spotify, Episode 1914 released on 12/22, Kara Siddharth.

The subject is cobalt mining which is necessary for any car or electronic device that runs on a battery. The main focus is the Congo which is where 70% of the worlds cobalt is. All the horror of how the miners are treated. Many missing limbs or get killed in mining accidents. Miners can start working in their teens, or as soon as they can break off cobalt. Mothers with children on their backs getting caked in toxic cobalt dirt.

If you want to hate electric cars a little more, listen to this episode. Then bring this up whenever someone says that electric cars are better for the environment.

To be fair, you've just described nearly every coal town in the U.S. and Europe during the Industrial Revolution, and nearly every current gem mining town outside of North America. The Race to the Bottom is nothing new...

yep. My grandfather was a coal miner in western Pennsylvania in the early 20th century. Very dangerous work, at the time. Although perhaps not quite as dangerous as his involvement in unionization of the mines. There is a pic of he and a friend standing next to his buddy's bullet ridden Model A courtesy of mining co. strike busters.

My grandfather was a coal miner in Harlan County, Ky during the same time. My father remembers hearing the gun fire way up in the hollers at nite as a very small child, and was pulled out of school for several months. This was the coal war of winter 30-31. When he did go back to school, there were bullet chips in the bricks of the schoolhouse. I guess that was why my grandfather decided to become a Methodist minister instead!

Or you could recognize that it isn't an EV problem and that it is Chinese businesses and the Congolese government who are allowing those people to be abused. Then do something productive like help apply pressure our government to apply pressure on the Congolese to make it stop and also to help make domestic battery production more viable so hopefully more ethical US companies are the cobalt buyers.

We really need a heart emoji!

Well said - and to add - not only pressure on our government but also our private companies. There's a massive ESG movement going on, much of which is not getting airwaves, at some very large corporations (both internally and from outside pressures, including investors).

Hi, Lesson for today:
1. The sun is 1,300,000 times as big as the earth.

2. The sun is a giant nuclear furnace that controls the climates of all its planets.

3. The earth is one of the sun’s planets.

4. The earth is a speck in comparison to the size of the sun.

5. Inhabitants of the earth are less than specks.

Study Question: How do less-than-specks in congress plan to control the sun?

Listen to the episode. The point is that people in our government would deny that anything bad is going on.

Help apply pressure? Ok, now we're assuming that US, China, and Congo don't have corrupt government, and that we actually have a voice and could make a difference. That's not reality. The politicians are going to follow whatever their supporters say they should follow.

Meanwhile, the environmentalists will keep telling you that EV cars are better for the environment. Maybe if you ignore where that cobalt is coming from. Also ignore that once the battery dies in the car, it is worth nothing and is now also a problem for the environment. At least it's not burning as much gas though. So that's better, at least while the car runs and has a working battery.

Then be consistent and hate your flashlights, headlamps, phones, tablets, and all the other items that use Li-ion battery chemistry. And hate all the things manufactured in China by Uyghur and other slave labor. It's an ugly world with lots of inanimate things to hate.

And I am very familiar with what is happening in the Congo. It isn't like you are the first to discover and write or post the info.

Wow, that's a lot of stuff to read. After reading sf most of my life, studying physics and engineering for ten years, and driving for 55 years, here is my take:
Today's EVs are a transition technology. We do not have the infrastructure to support widespread use of EVs. They are OK for short range commuting, but most people can't afford separate vehicles for commuting and regular driving. Most of the rhetoric I hear is from politicians who don't know a Watt from a bowling ball.
Any conversion of energy from one form to another has losses. Gasoline to mechanical; coal, solar, wind, or natural gas to electric; nuclear to electric; and electric to mechanical. Beat that problem and you might have something.
I think I will keep my '06 TJ and wait for Mr. Fusion. A flying Jeep - now you're talking!
