If I've just done my maths right then an AA battery is enough to lift 360 metric tons up 1m.
Edit: out by a large factor. Should be that many kg, not tons.
So lifting trains into the air is going to have its work cut out to match plain old battery technology.
- wmwmwm 6y agoI think that’s about a 1000x overestimate - about 1Ah * 1.5v * 3600s = 5400 J - that’d lift 540kgs up a metre (Maybe double that for an alkaline one)
- AndrewDucker 6y agoThank you.
- kmm 6y agoAn AA battery holds about 4 watt hours of energy, or 14.4 kilojoule. Dividing by 9.81 m/s^2 times 1 meter, yields about 1.5 metric tons. Not quite 360, but still quite a lot.
