Rand asks if a lunar colony can be crowd-funded. I ask the same of mars.
Amazingly we have an example for a jumping off point. Looking down the column of perks consider the perks a mars colony might offer in comparison:
Goal: $2b for a fully funded first landing of a dozen colonists.
A framed picture of the first dozen martian colonists. Signed on the back by all. This will be transmitted digitally from mars, but produced and distributed here on earth.
$100 (Limited to first 6,000,000 participants, 30 million after the second landing)
Title to one half acre of mars, selected by you, made available from registered claims in the possession of colonists.
All the above, plus we will rent your property for $20 per month ($240 annual) with annual option to renew. This rent allow us to use your property for industrial production of whatever we need on mars but not the right to remove minerals from your property.
All of the above, plus colonists will pay you $75 per month ($900 annual) for mineral rights with annual option to renew.
Thin film solar panels will be brought to mars. Eventually they will be manufactured on mars. Output: 500 watts per square meter. Cost: $100/m2. Mars One plans to take 3000 m2 (1.5 mW) with them from earth. Owners of property will have a place to put these panels which they may buy from martians and sell the power back to martians. The market place will determine all prices. Dust removal is a free service offered by the martians.
