Better have the sugar juices hooked up into your blood, you cannot breathe and drink at the same time.

Taking on hydration/nutrition drinks without breaking effort or position is a triathlete specialty. So, coincidentally, is pedalling for hours and hours.

Almost calls for an HPV triathlon: bike, copter, hydroplane...

I’ve often wondered what the efficiency of these fully mechanical systems is, and whether a completely electric system (without a battery or other energy storage) would be more compact, lightweight and efficient at allowing human powered hovering.

A Toaster like any other resistive heater is about as efficient as it gets in terms of power efficiency.

This guy won't make any copter fly, unless loosing 50kg.

human powered helicopters were an obsession of Leonardo Da Vinci. He spent so long trying to solve this problem and never could figure it out, amd here we are 500 years later, a little closer, but still a far way off
