You could do even better if the tube were carrying electricity instead of gas. Maybe it would have enough power to carry a whole bunch of people at once? Hey, I

- pcarolan 12y agoAgreed, the south shore chicago trains have feelers to harvest electricity as they go. Maybe a Tesla with a whisker on top could go indefinitely on long stretches of highway.

- ableal 12y ago(0.1 mm^2 is half the cross-section of AWG 24, getting close to hair thin.) I don't think you're correct here. For round numbers, let's take a 100 kW engine (134 hp), and suppose we feed 100 V. At full power, we'd be running 1000 Amps down that wire. Even at 1 kV it would take 100 A. Better get a superconductor. Or a much thicker power cable.
- pdx 12y agoHe was using the wire AWG as a way to visualize the size for those of us that are familiar with human hair, but unfamiliar with visualizing things that are fractions of a mm thick. He was not saying anything about replacing the amazing energy density of gasoline with electricity over a copper wire.
- kitd 12y agoHow about a pressure differential? https://en.wikipedia.org/wiki/Atmospheric_railway https://en.wikipedia.org/wiki/Atmospheric_railway Cross-section of pipe = available power
