>How much energy does hyperloop use to decompress the entire tunnel, run the air locks, and move the trains? whether it is more or less energy than it takes to keep an airliner aloft is kind of moot. Transport systems attached to the ground can be connected to the power grid, which is legally required to be at least 33% renewable energy by 2020. Jet engines can really only be powered by jet fuel, and exhausted directly into the stratosphere.
