If it were a viable source of energy do you think maybe somebody might have come up with it by now?

Aside from the lithium foe the batteries, most of the electric cars are made of plastic or a similar composite which is made from... Oil. The tires? Oil required for manufacturing. The fake leather seats (vinyl)? More oil.
Idiots thinking they’re doing something to, “save the planet” not realizing that oil makes up or is required to make their car.
Top Gear some years ago stated that one EV did more environmental damage in their lifetime due to the batteries alone (which have to be replaced once they’re down to 80% capacity - where do you think those go?) than an SUV in its lifetime.
People don’t understand how their prized possessions are made and components shipped for assembly.
Talk about ridin’ dirty.
So tell us how ICE have been detrimental to our planet so far.
Because we’re still driving them and the environment in the US is cleaner now than it was when I was a kid, back in the 60’s.
Getting lead out of gasoline did help reduce lead in the environment.
You are comparing apples to oranges. You’re actually being disingenuous about the comparison.
When you compare 130 years of ICEs to a couple years of EVs, and considering how the ICEs vastly outnumber the EVs, of course it’s going to look like EVs are not as damaging to the environment.
Make it a fair comparison. Compare a certain number of EVs to the same number of ICEs made in the same time period to current pollution requirements, THEN get back to us about which creates more damage to the environment.
you’ve certainly got that climate change kool-aid IV
Why does President Joseph Biden and members of his Administration ride in gas guzzling vehicles? Since they champion EV’s you would logically think they would have EV’s.
Why are Federal Government planes fueled by fossil fuels instead of solar panels?
It seems to me the radicals goal are not EV’s but control of our population. It is apparent to me fossil fuels are necessary for our lives. Farmers use diesel fuel for their farm machinery, truckers use diesel fuel to transport products from farms to warehouses and then to retail groceries. As Henry Kissinger once said, control medicine and food and you control populations.
It would be ironic if lithium production got shut down by the high price of diesel.
Biochemistry.
And, do you have a point?
I simply asked a question.
If it were a viable source of energy do you think maybe somebody might have come up with it by now?
Thanks for your input.

Driving an EV is a riot.
Hardly anyone looks at full-cycle efficiency of anything. All they see is from filling the tank or battery forward.
Unless the energy is free and there is no damage to mother erf, EVs are a lie of efficiency and ecology.
WITHOUT the mining, the drillig or the extraction the EV vs the IC efficiency is almost the same even though the EV is more efficient in burning power.
Gasoline is 33.7 Kwh per gallon and diesel is 40 Kwh per gallon. How much energy does it take to get a gallon of each one of these?
Coal fired steam plants are about 40% efficient and the transmission losses are about 20% and so out of the original 100 units of coal we get 100x.4x.8=32%.
When we put that electricity to work in an EV with a power train including electric motor we get about 77% of the energy stored in the battery back in the form of tractive effort, not including losses owing to the conversion from the plug to the battery. SO, from the original coal, not including mining and transportation energy, we get:
100 x 0.4 x 0.8 x 0.77 = 24.6% of the original energy in a lump of coal going to moving our EV and NOT including the energy it takes to mine the coal or make the battery or build the motor etc.
I wonder what the same number is for an internal combustion engine?
Refineries are about 88% efficient, the IC is between 17% and 30% thermally efficient with some race cars with regenerative features being up to 50% efficient. A similar number for the IC engine compared to the EV would be:
100 x 0.88 x 0.25 = 22% NOT including the energy and cost to drill for and produce the oil or to transport the fuel from the refinery. The number would be about 24% for the most efficient production engines of the day, equal to EV efficiency in full cycle.
Essentially, it looks like a wash in full cycle efficiency for coal to electricity to car vs. oil to fuel to car.
It is folly to think that energy from the sun via turbines or solar cells is “Free”. It is not but that is yet another set of calculations nobody looks at or cares about.
First Law of Thermodynamics, You can’t win. (Energy can neither be created nor destroyed)
Second Law, You can’t even break even. (In every energy conversion or transfer process the sum of the resulting energies will always be less than that of the original sources of energy)
I have to go change the cat’s litter box now.
When I grew up in the 60s/70s, we were told that strip mining was the worst sin ever.
Uh, I just like driving an electric vehicle. Instant silent torque etc. Does that make me immoral? Nothing new in tech as far as gas engines since, what, the Model T? I’m sure a lot of people thought indoor plumbing was immoral too🙄.

AND let’s give a thanks to the child laborers who mine the exotic minerals under the watchful eye of a war lord overseer.
Tesla's best-selling battery pack contains 7,104 individual 18650 batteries.
As I frequently say:

“The rest are really, really, really hard to solve”
