Overview of Status of Analysis, Design, Fabrication, Tests, etc.

- Friction drive with 2 rotary pumps
  - Status: assembled and tested
- Test results: 3-4 GPM
- Conclusion: need to implement a larger pump rather than 2 smaller pumps with this system to achieve 5GPM reliably

*Focused designs around single speed bike
