That is an excellent question, thanks!
The first 10,000 tokens sold at 1 Steem are budgeted for the purpose of powering up the @solairitas account. These will never be powered down.
The proceeds from token sales will be powered up and used to upvote until an accepted offer has been made, at which time the necessary amount will be powered down and sold to fiat for the purchase of the land.
Likewise, the sales will again be powered up and then powered down and sold to fiat for the purchase of equipment.
Once the project is built, all income from production will be converted to Steem and powered up for the lifetime of the project (except when necessary to maintain operation - the intent is for this eventuality to be infrequent if not nonexistent).
SOL represents the right to a proportional upvote in perpetuity. There is no promise nor guarantee of profit. SOL is not a security.
