The Physics is against you:
1. Batteries are not energy dense. They don't hold much energy given their weight.
2. Batteries immediately begin to discharge after charging. So they don't hold their charge well.
3. Batteries are environmentally damaging to make. Very damaging to make which is why their metals are only mined in a few places.
4. Batteries require expensive rare earth metals to make. They are only going to get more expensive with increased demand.
5. Batteries are difficult and environmentally damaging to dispose.
Hydrogen is a far better alternative. Burning Hydrogen, i.e., good old fashioned combustion, produces only water vapor as a byproduct.
Electric cars are a temporary measure until we switch to a hydrogen based economy. I'd say by mid-century.

@HoraceGreenley this is true though the government is not yet invested in Hydrogen pumps nor are there many hydrogen fuelcell cars for that reason

@SW-User Yeah, well at this point, Hydrogen on an industrial scale is not available. There are only two ways to make industrial quantities of Hydrogen:
1. Strip it off hydrocarbons. But this entails using fossil fuels witch defeats the purpose of avoiding fossil fuels.
2. Electrolysis of water. Cracking water into Oxygen and Hydrogen is the better alternative. You then keep the Hydrogen and discard the Oxygen into the atmosphere.
To make enough Hydrogen this way requires a lot of electricity. That means either using nuclear power and/or solar power.

@HoraceGreenley that is true also the cars are incredibly expensive 60,000 or so for Toyota Mirai

@SW-User Yeah, well the unit costs will come down with more being built.
SW-User
@HoraceGreenley would hope so
HoraceGreenley · 56-60, M
@SW-User Same thing is happening with electric cars now
SW-User
@HoraceGreenley thats true

@SW-User that's economics

@HoraceGreenley indeed well who knows what will be driving in years to come still hoping my next car is more affordable electric car after that shall see what’s available
