1. ERV – Power John Dankanich Task: Provide power all power needed on Mars surface. Given: Electrical Power Requirement Heat Energy Requirement Find:Best Possible Power Source Cost Risk Mass Feasibility

2. Various Power Sources to Explore Generators Solar Fuel Cells Wind Nuclear Starting point: 100 kWe 2,000 kW heat energy (brick making)

3. Generators Advantages: Reliability (99%, Cold Start) Fuel in-situ Cost ($1000/kW) Disadvantages: Feasibility (power to generate fuel) Mass (3500 Kg)

4. Fuel Cells Advantages: Reliability Feasibility Disdvantages: Cost ($3000/kW) Fuel

5. Nuclear Advantages: Feasibility Mass (2,500 Kg) High Thermal Output Disadvantages: Political Radiation Reliability (or cost of testing)

6. Solar Advantages: Reliability (99.9%) mass (2 kg/ m 2 ) Disadvantages: Size (300 W/m 2 ) Cost ($1000/W) feasibility

7. Wind Advantages: Reliability (99%) Lifespan – 30 years Simple Expansion Disadvantages: Cost - Initially high ($1000/kW on Earth) mass (structure) feasibility
