Thrust of the Paper: How to Learn In a New Cross-Disciplinary Area
Fertile area of R&D at interface between space and terrestrial micro renewable energy.
End-to-end efficiencies are small, even with space systems.
Innovation focus on sustainable alternatives for high Figure of Merit.
Steep cross-disciplinary learning curve.
Approach based on courses, testbeds, knowledge base development, learning resources, individual and team projects.
Testbeds approach enables hands-on experience, test cases for simulation, and enables continued advances to provide greater functionality for the same footprint.
Organizing testbed developments poses tradeoffs between timeliness, depth and breadth.
Evolved method of organizing and assessing student team activity is summarized.
Fertile area of R&D at interface between space and the terrestrial micro renewable energy.

MICRO RENEWABLE ENERGY SYSTEMS
Terrestrial Micro Renewable Power
Requirements for terrestrial micro energy systems
2. Efficiency is small even for Space power systems!
Issue is to achieve high Figure of Merit (but not above 1!!!!)
1. Low thermodynamic efficiency of heat engines with small temperature gradients
2. Large surface area per unit mass, resulting in high friction and heat transfer losses.
3. Highly fluctuating power
4. High fixed costs of power control and transmission subsystems per unit power transacted.
5. Generally high mass per unit power.
6. Need for energy storage
3. Innovation focus on sustainable alternatives that achieve high utility.
4. How To Deal With A Steep Cross-disciplinary Learning Curve
1. Two co-taught courses, set at 4xxx and 8xxx levels.
2. Continued knowledge base development using the courses and student reports
3. Development of testbeds through research Special Problems
