The End For Electric Cars? VW Develops New Hydrogen Tech: 2,000 Km On A Single Tank

Sure. Why not?
After all, they normally do (using an alternator) to charge their own starter batteries. How much electricity? There is actually a way to calculate that for the size engine you want to use.

Engines can be rated in watts or in horsepower (726 watts). Generators too are rated in watts (whether it's an alternator or generator). Simply put, the engine has to put out as much power as you hope to get out of the generator.
Watts is power.

Let's just take a simple example, using a Yanmar engine (found in small tractors such as the John Deere 1025R). This engine has a displacement of 0.638 cubic inches and can develop 10HP at 2400rpm, or 7260 watts. If you hook one up to a generator, the most you can get out of the generator is going to be 7260 watts.

It's a capable engine for these little tractors because you can hook it to a hydraulic pump and lift 800 lbs using the bucket (although slowly) and then drive off with it.

Can't the output wattage be amplified somehow?

What if the little diesel engine was spinning a large flywheel at a constant speed which makes the electricity by being hooked up to a generator/alternator with an inverter too?

PS: I doubt any tractor engine has only .638 CI displacement. 2/3 of 1 cubic inch? That's like plane-on-a-string territory.

You may mean liter, which is still like 638cc...I'm thinking something in the 2-500cc range and definitely diesel because it produces the most torque and high compression with a turbo for efficiency, 4v/cyl..and built heavy duty to power

a big sturdy electric motor for the drivetrain. Pretty much like a modified train engine, but with less torque. (as not THAT much is needed for a personal vehicle.)

Lithium is typically mined as spodumene (an ore based on lithium, aluminum and silicon, then smelted into lithium metal. The ore is typicall obtained through deep pit mining. Lithium mines are primarily in Australia, Chile, and China. There are large deposits in the United States, but it's difficult to get at due to lack of water and due to ecology laws.

Boron is mined from deposits of boron trichloride via surface mining. The US has a large mine in Nevada, U.S. It is also found in the SDTC, Chile, Argentina, China, Turkey, Russia, and Peru.

You're making shit up, dude.

Salar de Atacama in the Atacama desert is a shallow lake that produces half of the world's lithium. It is the largest salt flat in Chile.

No. You cannot create energy out of nothing.

A flywheel does not create energy. It's only a ballast of mechanical energy.

Wups. Yes...I meant liters. :doh:

Okay. So you are thinking of a smaller engine than what I gave the example for. You will have correspondingly less power available from the generator.

Watts is watts, dude. HP is just another unit like watts.
You can't create energy out of nothing. You can't 'amplify' the energy into more energy...not by using a flywheel or any other device.

I'm telling you it could work. Also an oil/steam compressor could work.

Nope. You cannot create energy out of nothing. Using an external combustion engine won't do it either.
A compressor doesn't run itself.

I do like the steam cars that Jay Leno has been collecting and restoring. Call me nostalgic, but I remember my days of working on a railroad that used steam locomotives. Great machines. That characteristic sound of a steam driven vehicle. I'll always have a soft spot in my heart for it.

Solar can.

Two things. First the numbers don't support your claim that an EV has to go over 80,000 miles before it produces less GHG than an ICE vehicle. Your source says it can range from about 15,000 miles to about 90,000 miles. That is a rather large range based on old data from as far back as 2013. You seem to not want to include the lower range in your claims.

Furthermore a lithium ion battery has a minimum life of 5 years of 2,000 charging cycles
Tesla warranties its battery for 8 years. So the average life of a lithium ion battery is not 5 years. The minimum life is.

Yes, I was citing an old article I read. 90K Is more than 80k. :dunno:


"That could be a problem for the U.S. Electric cars rely on lithium-ion batteries. China produces 76 percent while the U.S. makes only 8 percent.Jan 18, 2022"

https://www.grid.news/story/global/...roblem for the U.S.,U.S. makes only 8 percent.

White libs are so myopic and small minded. They can never see the Big Picture. :palm:

And the CO2 all this subsidized energy "saves" is a fart in a hurricane in the Big Picture. The $20 trillion that has spent promoting the hoax would have been better spent buying up pristine habitat and turning it into nature reserves and paying rangers to protect endangered wildlife.
 
.
The mid-March assessment by the battery supply chain research outfit shows that battery-grade lithium carbonate (EXW China, ≥99.5% Li2CO3) is averaging $76,700 a tonne, up 10% over just two weeks and 95% since the beginning of the year. A year ago, the commodity was trading at $13,400 a tonne.

As a result Tesla have been paring costs on their batteries.

Big difference. Electric cars exist. The means to manufacture them is in place.

EVs are made to run on coal. :palm:

Why do you think China is building a new coal plant every week. They purchase over half the world's production of EVs.

Because they have a terrible pollution problem., they are into solar, wind, and all forms of alternative energy more than we are.https://www.scmp.com/business/china...enewable-energy-leader-strong-capacity-growth People who think like you are spectators in the future energy development and the businesses they create.

China is the number one burner of coal in the world. Do you give a fuck?!

It would not be possible to run a car on coal without your precious EVs, ... unless we went back to steam cars. :palm:

Not only do I, but so does China. they are deep into alternative energy for that explicit reason. The tension is due to their financial expansion and the growth of wealth among the people. The demand is greater and greater. They have had a long history of coal plants. The future plans are to replace them. They are not old and stupid as the rightys. They are working for the future. https://www.nature.com/articles/d41586-020-02464-5 They are not "thinking" like you.
