The mining work would be a lot simpler and more productive if we can deliver and build more power generation on the moon. Here is an analysis for producing solar cells from lunar material Actual experiments have been performed by Alex Freundlich to make lunar glass and 1% efficient solar cells This is examination of large scale lunar solar power
Another $250,000 challenge is the moon ROx challenge. The goal is to produce 5 kilograms of oxygen from simulated lunar soil in continous process within 8 hours.
