2. Answers for the each Questions¶
What will it do?¶
give people indoor exercise opportunity, while generating electric power
- This will be used as an electric generator while people get some exercise moving their legs and/or arms.
- Also, the drive simulator motivates ( simple toy car on the rolled paper ) the people to continue the exercise.
- Various people can use this. Two legs, two arms, one leg & one arm, etc. If the drive simulator consists of the thick & rich-texture materials like felt, blind people can touch and feel it.

Project summary, as of this week (2020/04/08)
Who’s done what beforehand?¶
Many people made bicycle type ( or pedal & crank ) generator, but they are not suitable for the indoor use because they are heavy and bulky.
Also, there are many kinds of exercise machines but most of them are just wasting the energy, in other words, just converting the mechanical energy ( from human body ) to heat energy, not producing electricity.
