https://en.wikipedia.org/wiki/Energy_efficiency_in_transport

that table is thoroughly fascinating. i mean all of them, there's more than one table on that article

apparently walking is the most energy-efficient transport mode of all?!?!? apart from bicycles

what i find mind-blowing is that airplanes consume approximately the same amount of energy as cars and trains. I mean i can easily see cars and trains being on the same level, but i always thought that airplanes consumed like an order of magnitude more fuel than cars. considering how everybody keeps saying that "airplanes consume so much fuel" and such. crazy.

and also boats are less efficient than i thought? boats consume 16 L/100 km while cars, trains and airplanes consume 6 L/100 km?

The bicycle vs velomobile (latter is more energy efficient in chart) is based on high speed. velomobile is heavier, and uses more energy at low speed and stop and go traffic. Parking the dam thing onto a sidewalk is an ordeal that takes energy.

It's unclear that food energy used for exercise should count the same as fuel. Implies Wally lifestyle is bestest.

"On demand" is taxi-equivalents? Transit scores low with low occupancy busses. Air is optimized for most perfect economy, and chart likely created by that industry.

    Why the hell would you park a vehicle on a sidewalk??

    qualifies as a bicycle. OP's velomobile has no power assist. It is a recumbent bicycle (tricycle usualy) with an aerodynamic shell around it.
