A substitute for crude oil
Electronic crude oil — batteries!
This is a classic example of "substitution effect" in economics
The substitution effect refers to the change in demand caused by a change in the relative price of goods,
while consumers' actual income remains unchanged.
— Economist John Hicks
But I also want to share some of my thoughts,
Previously, I mentioned airplanes,
Due to the limitations of thrust-to-weight ratio,
Hydrogen-powered airplanes might be better,
And the retrofit costs are also lower.
The plan was set as early as 2022 for test flights in 2026,
Sometimes I feel like the timeline of this world isn’t real…
It’s as if there’s a destined arrangement behind the scenes!
Amazing!
