A brilliant, inexpensive, ecologically sound, healthy, and fun public transportation solution? This is pure genius! Enjoy!
I've loved earth-shelter, solar/wind power, pedal power, people power for 35 years. Why not pedal that generator to watch TV? Run your blender off compressed air? Store energy potentially? Use balance/counterbalance and water to open and close doors?
I am not alone with my simple low-tech solutions. What a great era to be alive! Ever more amazing strides in low power high tech devices and young folks like this with the energy and drive to execute another fabulous idea.
