The Ultimate Eco-Friendly Commute Solution

The graph shows transport efficiency (calories per gram per kilometer) vs body weight for various creatures and vehicles. And then there's that genius comment: "Imagine how efficient a salmon on a bicycle would be."

Looking at the data points, a cyclist is already super efficient at ~0.15 cal/g/km, while salmon sit at ~0.45 cal/g/km. Combining their powers would create the ultimate transportation revolution! Just picture a salmon pedaling away with its tail, water splashing everywhere. The ultimate eco-friendly commute solution nobody asked for but everyone secretly needs.

Finally, a practical use for all those upstream swimming muscles! NASA engineers are probably kicking themselves for missing this obvious breakthrough in biomechanical efficiency.
