A person on a bicycle is by far the most energy-efficient among animals and machines per distance traveled relative to body weight. The bicycle is magic.

a "wave-piercing trimaran", and it's way high
though catamaran is a lot lower.
Not sure if that catamaran is a hydrofoil
Each appropriate for different kinds of trips.
Sounds like something 30 salmon in a trenchcoat would say.
Still surprised by jets though, but with very long distances it gets easier, I guess. I wonder how Voyager 1 (at 111 AU) would compare.
It's an invention just 200 years old! Imagine how different history would have been if the minutemen or Paul Revere rode fatty!
But walking is as energy-consumptive as a car? Huh?
Out here in the netherlands we were lucky that there was enough public outcry before they decided to bulldoze everything
A car can get places faster than a cyclist.
Jstor gatekeeps knowledge, but Sci Hub is a friend: https://2024.sci-hub.st/6606/19461f1a1e78bc373f865e4d01687ff8/[email protected]?download=true
You should be able to see all replies. 😉
to be fair to the animals you could include things like acceleration and deceleration, which the salmon and bicycle are not optimized to do.
for machines you could use passenger miles, ie add the miles travelled per passenger
This pic in There is No Planet B by @mikebernerslee.bsky.social is why I got my e-bike!
Same little bit of land, but wow look how much further you can go on an e-bike!
Distance record ~ 3000 km

The car with a hollow dot is a full car, which naturally does better than a bus system which is not full 100% of the time.
“looking at the data from Japan in table 20.8. At 19 kWh per
100 p-km and 6 kWh per 100 p-km, bus and rail both look promising.”
Based on the date on the website, the graph is about 10 years old.
Anyone aware of a more recent comparison?
Lots of electrical vehicles have been created in the mean time. Average size and weight of cars has also changed. Electric bikes became popular...

It would be interesting to verify the data in that plot.
I wonder where e-bikes would land in the efficiency plot.
Is that gap between man and man on bicycle where race shops make all their money?
2) Is there a chart with a buzzard on there? They seem stupendously efficient.
Even a slight uphill would decimate the efficiency of the bicycle compared to the change occurred by a pedestrian, let alone a flying bird.
QED.
So a Big Mac is good for 563/10.5 km.
ca. 50km on a Big Mac. Makes sense.
Thanks
