There needs to be wartime like effort to change our life styles away from fossil fuels. That means there will need to be movement to do things for ourselves, like building your own transportation. Don't wait for politics to fix what is wrong with the world.

Pedal Electric Hybrids
It’s about time that someone by passed the muscle
powered drive chain. But I don't see how you can bypass the batteries and still
climb hill with cargo. So what are the advantages of pedal electric? Charge the
battery a little while you ride? It makes more sense to put all your money into
the latest battery technology.
I am able to generate only about 40watts with my bad knee, and a heavy fly
wheel. Most athletes would not be able to maintain better than 100
The best way to avoid using a fly wheel would be to use a rotor crank:
Use a high voltage motor to generate power at a
reasonable pedaling speed, and then use a hub motor that uses very little
electricity to move.
