You may not have a choice in the matter as more and more countries are thinking of/implementing ICE bans in the near future.

We do have a choice because, on paper, we do have a choice in choosing those countries’ politicians. I know I’ll never give my vote to a politician keen on banning gasoline cars. It’s sadly also true that the technocrats actually taking those decisions are a lot less directly accountable, but nothing that a second “yellow vests” movement won’t be able to fix.

They're unlikely to succeed because if the massive tax on poor people (ICE bans) actually gets implemented, all of the poor people who are forced to buy an unaffordable EV will vote for populists promising to unwind the bans.

Let's consider Cessna-172S ([4]). Its characteristics: - 130 kW engine, Lycoming_O-360 that weighs 117 kg. For comparison, an electric motor of this range would weigh 11-13 kg (at 10-12 kW/kg, [2]). That saves 100+ kg weight immediately and we can put 50+ kWh batteries instead. - It carries up to 200 liters of kerosene ([3]), which weighs 164 kg. We can place 82 kWh of batteries instead. - The engine consumes around…

> quite practical for recreation and short flights Perfectly agree with everything, but 1.5hr may be very short if you need to have 30 minutes of reserve at landing. On the saving side, you don’t have to have an alternator to transform ICE energy into energy for the dashboard instruments. On the downside, you now need to heat the cabin manually, rather than reusing the ICE heat.
