National power grids and nuclear powerplants are somewhat irrelevant to putting electrical airplanes in the air.

If you could achieve the energy density required for aircraft batteries with electric, major airports would require their own powerplants.
ATL would need at least 4 reactors due to the down time for refueling.

At least 100 nucular panner plants, that's my new job when the autobots take over the flying.

Incorrect, obviously. They wanted to kill certain groups of people for their own gain.

We will work together to reduce Our Earth's population, at some point. The sooner we do it, the less deaths from wars/disasters we will experience...

…just a layman’s perspective – I’m for whatever the hell works
Boeing and Airbus have been working on electric taxi motors powered by the APU, so you don't need to start the engines until you are close to takeoff time. No tug or towbar needed...

GF
It's mostly in deficit spending that future generations will have to pay. There is a large amount in subsidies to businesses. For example, all pax aircraft made today are subsidized about 50%, so when an airline buys one, they pay about 1/2 the actual cost. Trucks driven in the US pay a fee to use the US highways, that cover about 10% of the actual cost. There is quite a bit in general taxation, however.

It will be quite difficult for all of us to work together to achieve the population goal that we will pick, but we will do it, because we will be forced to do it.

What he's saying is the AMOUNT of solar (and other renewables) required to generate our power needs is astronomical. Especially when you start transitioning transportation infrastructure to electric as well.

Nuclear is very safe, what has made it (somewhat) unsafe is using 1950's design...no new modern nuclear plants have been built.

China and India currently produces 60%+ of their power with coal (and increasing). Replacing that with renewable is a pipe dream. Nuclear would provide instant reductions in smog and contaminates. And it would also provide the needed power without sending people back into caves.
China is shutting down 1700 coal electrical plants, and ramping up solar and wind, and electric vehicles, ASAP, using LARGE amounts of gov't funding to aid in the transition.

That’s news to the Chinese and Greenpeace.
