Re: Electric planes?
Electric batteries are about fifty times the mass of airline fuel for a given amount of energy. Plus the batteries aren't consumed during flight, so the landing mass is the same as at take-off. And solar doesn't help - a panel the size of the aircraft would only produce a tiny fraction of the required energy.
The only realistic way to reduce airline fossil fuel consumption at the moment is to fly a lot less. And we're currently proving that this is perfectly viable.
