Couldn't a small diesel motor make electricity?
No, China has a nice battery tech, they dont sell it to Turkiye. They sell it to many other countries. They were afraid that we will copy it. The battery has a life of 80 years. So you will never have to renew your car's batteries. Classic lithium iom battery has a 5-8 years lifespan and dies, which is currently been used in phones, laptops, electric cars. Its also pretty heavy. The new tech battery can be recharged 30.000-50.000 times, so about 80 years if recharged daily. An electric car with a lithium ion battery needs to be plugged in for 7-8 hours (with slow charge) can be charged in 5-10 minutes with new battery tech. We copied it, we produce its lithium from boron. We spend billions to Turkiye's first car TOGG, which is fully electric powered.
None of this Hydrogen or battery vehicle stuff works when a storm takes the power out.
Gasoline pumps depend on electricity to work. They try to have either a generator or a set of batteries at all gas stations, but there is a need for electricity. In theory, hydrogen would be the same. Batteries can at least be recharged with solar or wind, but gasoline requires a lot of energy connected to grids.

You cannot store or trap heat. Heat has no temperature.
An actual greenhouse works by reducing heat. The enclosed space prevents convective heat, but still allows most radiant heat from the Sun to enter. Infrared light in the sunlight can be absorbed and converted to thermal energy. A greenhouse does not stop radiant heat. It still cools off just the same at night, even if you never open the roof vents (which are there to allow convective heating).
No gas or vapor can prevent convective heating or radiant heating or conductive heating. They are fluids.
The ignorance is yours. You are trying to discard the 1st and 2nd laws of thermodynamics and the Stefan-Boltzmann law.

Nicely put! They also go against scripture from the Church of Green and the Church of Global Warming.

Oddly enough, you will find it tough to pump gas at most gas stations without power as well.
Hydrogen fuel (sold as compressed gas) can be 'pumped' without power, but the metering system that calculates your cost doesn't.
Since hydrogen doesn't naturally exist in the quantities needed, you have to make it. There are two common ways, both of which require power:
1) Catalysis using natural gas, which steals the hydrogen from methane, leaving behind carbon.
2) Electrolysis, which steals the hydrogen from water using an electric current, leaving behind oxygen.
It is possible to run the refinery distillation process without power. Pumping product around requires it though. If necessary, generators can provide that power, and the refinery after all has a ready supply of fuel.
It is possible to hand pump gasoline, or to use a generator to power the pump. Gas stations, after all, have a ready supply of fuel.
But you can't charge an electric vehicle without using fuel to do it (and lots of it).

There are still some issues though. It takes a significant bit of time for a fuel cell to 'power up', so to speak. You want acceleration NOW. To cover this, hydrogen cars have a significantly sized battery to cover the gap. It ballasts the demands of vehicle over the fairly slow ramp up times required for the fuel cell. Once the fuel cell is operating, this ballasting battery is recharged. Other than that, they operate much like a diesel electric locomotive, using fuel to run a generator (the fuel cell) that in turn powers the traction wheels. The only real difference is that hydrogen is used as the fuel, and the generator isn't a mechanical one. The other difference of course, is that hydrogen has much less available power by volume or by weight than diesel fuel does. Hydrogen has more power by mole, but that is not how fuel is sold or stored in tanks.
Another issue is making sufficient hydrogen. This is a power hungry process.
Another issue is compressing and preparing the hydrogen for use as fuel. This also requires a significant amount of power. Hydrogen is compressed to some 3000psi.
Another issue is the fuel delivery problems themselves. Putting hydrogen into the tank of a hydrogen vehicle causes the nozzle to freeze to the vehicle, made cold by the pressure drop (see the ideal gas law). After fueling, you have to let it thaw before you can remove the nozzle. This can take a half hour in some cases. This problem has been noted at hydrogen fueling stations scattered across the southern portion of the SDTC, mostly around L.A.
So while it all sounds nice and eco-friendly (what does that even MEAN??), hydrogen is not all that practical a fuel due to the power requirements of making it and compressing it, and the mechanical problems of storage and delivery to the fuel tank of the car.
I am not against the hydrogen car, the EV, or the ICE car (both gas and diesel). I am against mandates or subsidies favoring one or the other. That is fascism. There is no other word for it. It is government manipulation of markets, in this case, the automotive market.
Let the market decide. If you want to buy an EV, go for it. If you want a hydrogen vehicle, go for it. If you want an ICE vehicle, go for it.
So far, only about 1-2% (depending on you ask) of the cars on the road are EV. Even less is hydrogen. People are choosing to drive ICE vehicles. Yes...new cars sales are mostly ICE vehicles.
The people have already decided what they want to drive.

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.

Lithium isn't boron. Watts is watts, dude. It takes so many watt-hours to move a hunk of anything a certain distance. It is not possible to ram that many watts into anything like a car in 5-10 minutes. Lithium is lighter than boron. It is actually the lightest metal.
Your claims you got from this ad are not possible.

It is an electric vehicle in the same way a diesel electric locomotive is an electric vehicle.

Why do they have to? Why do you support communism like this?
You should stop making precise comments on subjects you dont have enough info about. Lithium is produced from the wastes generated during the processing of boron and there is the only one country (officially) in the World that does this.
Communism? You say the dumbest shit. The government has been involved in research for a century. https://issues.org/bernanke-researc...ny countries directly,like the R&D tax credit). How damn stupid are you?

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.

Why are you so fucking stupid. You have no touch with reality. All industrial countries finance research. https://en.wikipedia.org/wiki/List_of_countries_by_research_and_development_spending I wonder , how damn stupid are you?
