You can't drive to the grandparents on the other side of the state... You can't do most of the things that I do with my cars... Until this changes, these battery powered cars are good for the metro areas only!
Surely there must be a way to throw a diesel-powered generator on the bed of that Cybertruck and use it to range-extend the vehicle. I have no idea what the efficiency of that would be but perhaps someone with gas-generator experience knows how much charging can be done per volume of fuel, and what size generator you would need to keep up with the current drawn from the battery. In a pinch, you would never be out of juice... no more range anxiety. And when you can charge up from the grid you do that.
I'm guessing running the Tesla (or DeLorean) on the fuel-powered electric generator wouldn't be as efficient as directly driving a car on fuel. Then again, you would be charging up batteries with it so whether you are moving or standing still, that generator will always be going towards charging you up which can allow you to use that energy later (again assuming you pick a generator with an output greater than you are consuming as you drive the vehicle).
Any back-of-the-envelope calculations by someone who knows the output of a generator and the fuel used per kWh of electricity produced? Apparently Tesla batteries have somewhere between 60-100 kWh capacity. I'm looking at a 2200 Watt generator on Amazon and it says something like this:
Truepower technology provides clean, stable power ideal for sensitive electronics, tools and appliances while the 1.2 gallon fuel tank allows 10.75 hours of run time at 25-Percent load.
So does that mean 25% load on a 2200 W generator is 550 W? So it could deliver 550W for 10.75 h on a 1.2 gallon fuel tank? How does this translate to trying to charge a Tesla? Apparently it can take up to 4 full days to charge up a Tesla fully on 120V outlet.
