EVs and Maintenance Costs
Is the creator of the meme at left serious? From this piece:
Electric Vehicle Drivetrains Only Have 20 Moving Parts Compared to Over 200 in Conventional Automobiles – This means lower maintenance costs and a radical shift in auto industry job skills.
While most of the media attention focuses on the big picture issues of how green-energy EVs are destined to help mitigate climate change by eliminating use of fossil fuels and will ultimately lower the costs of driving for consumers, there is another significant impact that deserves more attention too. That is the relative simplicity of EV powertrains and implications for lower maintenance costs.
Many EVs don’t even need a transmission. Those that do use a much simpler, single-speed system as opposed to the multi-speed gearboxes in gas-burning vehicles. For example, Tesla’s electric motors only have two moving parts and use single-speed “transmissions” with no gears. The company says its drivetrain has about 20 moving parts compared with 200 in conventional drivetrains. Similarly, the all-electric Chevrolet Bolt has 80% fewer moving parts than a comparable car with a gasoline engine.
And absent the power train, think about other entire systems that do not even exist in EVs, e.g., fuel delivery, pollution control, and exhaust.
This is why auto dealers dislike EVs; electric transportation virtually kills two profit centers: parts and service.
Re: the meme here, astrophysicist Neil deGrasse Tyson has said, “If we can explore colonizing Mars because we’ve ruined Earth, we can certainly fix Earth.”
As shown at left, Trump’s reverence for the world’s authoritarian figures is among his most obvious, most glaring characteristics.
What physicist Brian Greene says here is true.
From the Wall Street Journal:
…. seems to have dried up.
Most American women who live within, say, 25 miles of downtown anywhere are educated and career-oriented. They deeply resent the Republicans’ far-right position on abortion, and oppose most of the other principles of Trumpism, e.g., white nationalism, the rejection of science, and the Big Lie.
As astrophysicist Neil deGrasse Tyson puts it, photos like the one here are evidence that we live in a country with a) free speech and b) failed education.
There has been much discussion concerning the relationship between educational levels and political leanings. There is no doubt, for instance, that one is more likely to encounter a Trump supporter running a hardware store in rural Mississippi than teaching cardiology in a university hospital in Massachusetts.
The numbers at left re-enforce my belief that Lincoln should have accepted the secession of the Confederacy in 1861, telling them:
