Or they could carry about 2 liters of kerosene.

Kerosene contains 10 kWh of potential energy per liter (about 800g). So yes you’d need 3kg of kerosene to provide 24kWh of energy. But that is heat energy.

An efficient gasoline generator produces 1.7kWh per liter. So for 24kWh, you’d need to consume 14L of gasoline and also carry around the generator. I would personally prefer the battery option.

And how much does it weigh?

The smallest one I can easily find is 10kg.

My 1.6 KW generator is around 40 lbs. without fuel. and about the size of a carryon. Not at all practical compared to a battery.

Plus a machinery to convert it to electricity :)

Perhaps convert an old lawnmower and power drill to power one’s desktop PC? Simple and perfectly safe/convenient with additional respirator and ear defenders.

Cue this old Nissan Leaf ad: gas powered everything

Wow 11 years ago. i switched to an electric car recently and still frequently smell exhaust fumes from cars that are running rich or burning motor oil. I might be alive to see the end of internal combustion engines in cities which seems inevitable now.

Living in a urban area I can see the end of the ICE in the next 10-15 years. The game changer in my opinion is the ebike, if we can get just a slight shift in thinking, eg taking the ebike to the gym or store instead of driving an ICE car doesn't stand a chance in the city.
