Question |

Bicycling up a hill
versus walking:
Bicycles are incredibly
efficient machines. However, the other day I
noticed that walking up a hill was much easier than
riding my bicycle up it as I had done on a prior
day.
So this week's
question is a double question: 1) Why is it so much
easier to walk up a hill then it is to ride up the
hill? And, 2) How could a bicycle be
re-engineered to provide for easier hill climbing?

A word about our art.

Thrust Vectoring
Motorcycle Fairing
A windshield on a motorcycle, car or any vehicle
serves the purpose of pushing the flow of air out of
the way of the passengers. The thrust
vectoring motorcycle fairing replaces a windshield
with a ducted fan that directs a blast of air up
from the front of the motorcycle. As the
vehicle travels forward the jet of air is angled
back and over the rider. The rider ends up in
a comfortable bubble of calm air.

Hybrid Hot Hydrogen Balloon
The hybrid hot hydrogen balloon combines two lighter
than air technologies: a hot air balloon and a
hydrogen balloon. A hot air balloon works by
heating the air within the balloon. The air
expands which causes the mass of air contained
within the balloon to be less than the surrounding
air. The result is that the hot air balloon will
rise. A hydrogen balloons works well without
adding heat because hydrogen is lighter than air.
Now suppose the hydrogen is heated the way a hot air
balloon is heated? The efficiency of the
hydrogen will increase.

Hybrid Multi-bike Car
The hybrid multi-bike car unites two efficient vehicles types; a small
electric car and up to three electric bicycles.
As electric vehicles increase in popularity more
families will end up with a mixture of electric cars
and electric vehicles. Perhaps it might be
beneficial for the electric car to act as a sort of
docking station where up to three bicycles could be
connected to the rear of the car. The added
bicycles, complete with their own batteries and
motors could help power the car and also provide a
novel way for small groups to pool their resources
together for a commute and then break apart to reach
their final "last mile" destinations.
