Description:
We are looking for suppliers of flywheel energy storage modules suited for the following requirements for a lunar surface spacecraft:
- Shortly before sunset, temperatures at the surface are 390 K (116.85 °C, 242.33 °F) and we have full power generation from solar panels.
- Shortly after sunset, temperatures drop to approximately 100 K (-173.15 °C, -279.67 °F) and we will need to heat critical components to avoid damage from thermal stress etc.
- We estimate, roughly, that the thermal power we need is approximately 30 W throughout the lunar night.
- Lunar night is approximately 355 hours long.
- Shortly after sunrise, we regain full power generation from solar panels again.
- The lunar environment is a natural vacuum.
- Also note that the nighttime temperatures are cryogenic, enabling superconductivity.
- Low mass is preferred over low size.
We are primarily looking for off-the-shelf products. We do not have money to fund development of new products matching these requirements. --Anders Feder 22:03, 18 February 2009 (EST)
