Battery based electric vehicles of today and tomorrow.

I’ve never been swayed by the “it takes too much energy to make hydrogen argument.”
If my solar panel makes hydrogen fuel that’s equivalent to a gallon of gasoline, but I had to collect the solar equivalent of 10 gallons of gas, so what?

Because you could have had the equivalent of 10 gallons of gasoline rather than just 1.

Or, you could have built your solar system for 1/10th the cost.

The cost of solar generated electricity depends on the time value of money. There is very little ongoing maintenance or repair cost.

It’s one thing, if we have to grow 100 acres of corn to get (say) 20 acres worth of ethanol out of it because the refining process consumes the other 80 acres (that 80% going into the environment prior to consumer use). Or if you need 100 barrels of oil to make 50 barrels of fuel, etc..

Ethanol and hydrogen are the same sort of fool's errand. Neither is sustainable. Both require cheap energy from other sources to be anywhere close to economically viable.

But when wind or solar is powering the process, and the ingredients and final exhaust is water, so what? It would seem the efficiency matters less.

"Solar and wind" are only a small part of the ingredients. The hardware to convert solar and wind to useable energy is the greatest consumer of resource. Then amortize this cost over its useful life.

The incremental cost of utility power generation is only about 1.5¢/kWh. Delivered to your home the cost is over 10¢ to pay for the generating facility and distribution grid.

Curious how quickly one forgets, "time to break even", when it is not convenient to one's argument.

I'm a bit confused.... Why does a wind generator need huge amounts if any of rare earth elements?
A wind generator is just that... a generator
What is so different than our car generators.
We have had wind generators for years before rare earth elements even were a thing.

It is a false argument to accept at face value the claim "rare earths" are actually rare. Rare earths are plentiful but for how globalist politicians granted a monopoly to China. There is no reason Americans can not process rare earths every bit as cleanly as everything else we do.

Permanent magnets in generators benefit from alloys of rare earths. The stronger the magnet in the smaller the space the denser the fields and more efficient the generator (or motor).

Is also false to pretend "rare earths" are consumed. Rare earths in magnets or batteries are still there waiting to be recycled or repurposed. Just as we find with aluminum beer cans. Or lead-acid starter batteries.

I read excerpts from his book that were pretty well sourced. He said the giant windmills you see contain large amounts of rare earth metals
Im guessing the motors or other parts have rare earth magnets?

Rare earth elements are common - they're spread all over, but concentrated deposits are rare (that's where the term comes from).

Hydrogen fuel makes more sense then batteries, IMHO. Hydrogen is the most common element, virtually inexhaustible.

Can we all produce enough of our own hydrogen at home to run our cars and trucks? power our chainsaws and generators?

Are lithium batteries really here to stay? batteries had a huge boost when Alkaline came out. didnt last.. Lead – Acid is fading out. Ni-Cad is going away. Why not Lithium? Given its chemical makeup of rare earth elements it cant last.
Why not salt?
There is a huge push for using plain old salt to power the next generation batteries.
Sodium-Ion is doing very well in testing. Japan it testing cell phone batteries, Storage batteries are showing promising results for fast charge and long term performance.

Combine a new battery technology with solar charging we can see tremendous change very soon.

A lot of you say solar cant perform but the world says different. Many countries including ours are spending bazillions of dollars not only in research but building megawatt infrastructures.

Its going to be a exciting change! Battery power is coming.

Gale...

Your spreading and thinking click bait claims are going to be real into the future.

It's a cult...

Okay then I'll cut your five mandated clicks on this thread down to three per day.

I'm guessing your Dad will never own an EV.

And he heats his house with his own gas well.

Check the master breaker in your electrical distribution panel.

I have 200amp service. That will cut the cost of installing a 240V charger that draws 80amps.
Tesla - 80 amps
Dryer - 30 amps
Microwave - 10 amps
Double oven - 50 amps
TV/ lights/ coffee maker - 3 amps
A/C - 20 amps. (nat.gas furnace and hot water heater and stovetop)
Total = 193 amps.

If I had an all electric house I would have to get 250 amp service or just be cautious of what I'm using when the Tesla is charging.

Waymo will partner with China's Geely to develop electric robotaxis

Waymo, the self-driving arm of Google's parent company Alphabet, and Chinese carmaker Geely have partnered to build electric, fully autonomous ride-hailing vehicles to be used across the united States.

This is another article on UK looking at ending car ownership but they already have places where gas cars can't go in some cities that have been longstanding.
