Yes, actually:
(Besides a 'velomobile', anyway ... which is basically just a bicycle with bodywork for better aerodynamics.)
Death sentence to whoever chose to animate a fake scatter plot over this thing. And yeah velomobiles are just speed-optimized bicycles.
This is so cool. Why do I intuitively expect the efficiency should increase with the Y axis instead through? It feels somewhat upside down?
The Y axis is cost of transport, low cost = high efficiency.
Mice should be ashamed of their inefficiency.
Correct me if I'm wrong, but I assume that the main upside of a velomobile is removing the un-aerodynamicality of the human on it
Which makes me wonder whether a bike without a biker will be more aerodynamic than a velomobile
Finally a graph that dares to compare cows and jet fighters!
Probably not the only graph that does so. Both are relevant sources of greenhouse gas emissions as well, so they probably share some graphs on the topic of climate change.
Now if we could just get a salmon on a velomobile
Velomobile looks like fun but they cost so much. Seems like they are typically custom built and use carbon fibre. So several thousand or more. Meanwhile my bike was like £600.
I wonder if you could produce fairing kits for common recumbent bikes and split the difference.
I think it's because they are made in such small volumes. Shame, as they look cool.
curious where lighter than air vehicles and trains end up on there
Blimp efficiency depends on size, a big one would be on the bottom right. But then some wind would send it tumbling around and it would crash into Jet transport and Horse, rapidly disintegrating as it pulverizes Human on a velomobile against the bottom axis.
Same as sailing ships I suppose, if you are just using the wind like a hot air balloon anyway.
It would be very difficult to measure how much energy (in calories) a sailing ship is using in order to move.
The notion of "fuel efficiency" kinda stops making sense for a sailboat.
