Aboard an enclosed recumbent bicycle in Nevada today, Canadian Todd Reichart has claimed the world record for human powered speed. The annual World Human Powered Speed Challenge draws cyclists from around the world seeking to push the limits of pedal-powered motion, but it was the 33-year-old who left the competition in his wake to clock a top speed of 85.71 mph (137.9 km/h).
...
The pilot sits in the recumbent position, with their legs out in front of them, in an enclosed capsule crafted with aerodynamics as a driving principle. Using a camera mounted to the top of the vehicle and a video monitor to see ahead, Eta was expected to offer around a one percent improvement on performance compared to its predecessor, according to the team's computer simulations.
Pretty cool, but their human-powered ornithopter is possibly cooler.

Why would a bicycle count and not, say, a jet engine, or climbing then jumping?
What if the fuel for the jet were synthesized using a human-powered energy source?

The sythesis/human-to-fuel process would have to *also* be human-powered.

Looks like using legs or arms are the only way to qualify as "human-powered".

It is all about direct and continued (individual?) human effort to produce motion. Jet engines and motors of all types are produced by humans, but the motion they give rise to is produced by using external chemical means to directly drive external machinery--no humans necessary. (I won't contemplate humans as fuel.) With jumping, cannons, slingshots, etc, no continuous effort is involved. I'm sure using skates, a skateboard, or a non-motorized scooter would count under the same conditions as the bike.

I got a big beef with saying it’s human powered when there’s a camera and display involved.
If he petals a generator to power them, then why can’t he petal a generator all night long and use an electric motor to power the bike the next day?

I would have that beef too if the video is battery powered rather than from a generator driven by his pedals in real time, which I doubt.
In organised cycle racing, things using batteries like radio contact with the team manager and heart rate monitors are allowed (but not always), it being arguable that they are not essential to the performance. In the case of this record however, the camera and display do seem to be essential, to see where he is heading. He could have used a mirror somehow to save argument.
