1) That’s a boring video
2) No, he does not have a science background. How do I know?
3) The use of the word EFFICIENCY.
Electric drivetrains are around 80% efficient converting electrons to motion.
Gasoline drivetrains are around 20% efficient converting gasoline to motion.
The problem is not the drivetrain, it’s the volumetric and weight ratio to amount of potential energy in the ENERGY STORAGE (for example liquid gasoline’s potential energy vs a lithium battery’s potential energy).
Now, why the big fuss about electric? Well, we have > 100% and no telling how much spent developing the gasoline engine, and it’s still 20% efficient. We have not spent much time on electric drivetrains (for cars) and they are 80% efficient. In fact they recently went from 50% to 80%.
Also, the battery (which determines the amount of electrons stored per cubic foot and per pound) has been improving at an astounding rate. Basically batteries before 1990 had not changed much from 1890.
There are battery technologies in the lab and in development that promise 3x the power ratio, faster charging, and longer life. If those come into commercial use at a reasonable price, you will have a car with 1000 mile range, that refuels in 20 minutes, and the battery would last longer than the car (10,000 cycles) - that’s 27 years of full charge/discharge EVERY DAY.
I don’t give a flip about the so called gloBULL warming, etc. It’s about the best car for the money - best performance, low maintainence, and reliability.
BONUS: Self-Driving will happen. I have an AI background (and a patent). And they will be way safer than you can drive.
So, where does the power come from to charge these EV batteries?
No thanks

They need to bring that old British TV Show "Danger UXB" back to life.
They could set it in Miami and call it "Danger lithium-ion battery UXB."
Each week they would portray a different home or business burned to the ground or a collision that caused the battery compartment to be compromised and ignites on the highway.
“Electric drivetrains are around 80% efficient converting electrons to motion.

Pure BS. You’re comparing apples with potatoes. You’re including the energy generator in the ICE “drive train”. If you look at only the drive train past the engine the efficiencies are not that different.
To do a fair efficiency comparison you have to include the efficiency of the coal fired electric generator to charge the batteries, the transmission losses, the charging and discharging losses, etc.
If you do that, the ICE is actually more efficient.
“BONUS: Self-Driving will happen. I have an AI background (and a patent). And they will be way safer than you can drive.”
Self-driving cars have the possibility of systemic bugs in their AI. In other words, all cars of a particular model (and year) could have the same incorrect AI behavior which is a safety hazard.
We have seen this sort of thing often with conventional cars, where all instances of a model have a safety recall.
Human drivers all drive slightly differently and thus almost never suffer from “systemic failures” (DUI being one of the few exceptions).
Finally, “way safer” for whom? The occupants of the car (you and your family) or the DEI goals of the those who “train” the AI? (Have you looked at the rules by which software development, such as Google’s Gemini AI image generator, has been done recently?)
Good post. The electric cars’ time just isn’t right now. The government forcing them on us is the problem.
And the average EV is an ecological disaster. To manufacture each EV battery, you must process 25,000 pounds of brine for the lithium 30,000 pounds of ore for the cobalt 5,000 pounds of ore for the nickel, 25,000 pounds of ore for copper Digging up 500,000 pounds of the earth’s crust For just - one - battery.
And the efficiency of producing the raw materials? Not saying EVs aren’t the future (they have been the future for over 100 year). But the production and disposal of them seem to cancel out any benefits of traditional petroleum based system. My 30 year old Honda gets 30 per gallon. Will anyone ever be able to say they have a 30 year old battery powered cars. Physics is a bitch

New Attack Against Self-Driving Car AI
[2024.05.10] This is another attack that convinces the AI to ignore road signs:
