Private Enterprise- To mars

I was actually thinking of "solar power" for heat and light and possibly electricity.  Cosmic material striking the outer hull would be repelled by the nanotubes that are 900 times stronger than diamonds.

A business plan in what area?  One where we get people to donate to science so the kinks can be worked out?  Or one that finances the crystal farms?  Or one that invests in making the graphite sheets?  Or one that invests in miniature robot production?  Or.........what?

I think we should get investors to finance a space probe to Iapetus so we can see how it was constructed and use it as a blueprint
