What do you consider current rates? They improve slowly, maybe 3-7% a year. Last I looked, batteries are so much worse in terms of specific energy than fossile fuels that we're looking at several decades before electric flight becomes practicable (except for very short distances and training flights).
- rictic 5y ago7% a year means doubling every decade, 3% means doubling every two. Fossil fuel efficiency isn't moving at nearly that rate. If current rates continue, battery powered jetpacks should be compelling within 60-120 years
