Eminent domain can be used: in solar farm operations. To place “micro apartments” underneath the solar grid. So long as you pay for the change, and accept all legal risks. As well as accounting for any diminished: “of income”, as could occur do to your change. The right is simple; a public need exists; and it costs the solar farm operations; absolutely nothing. Therefore it is a non-starter in court. Because these are set into place for a minimum of twenty years; and using property that is otherwise abandoned underneath that emplacement of a business: without disrupting the business or its income; is within public rights. To house its citizens appropriately; while not abusing the property or causing it “general harm”. If the property is changed from a solar energy producer; first chance to buy belongs to the “government entity”; in charge of providing housing. Claims of “not in my back yard fail”; policing and its methods will fall in place accordingly. People NOT suited to “living here” will be removed to other places, and will not come back.
The simple way to raise the solar field is: hook up large sections to a small crane. Then cut the lower frame structure; lift, and then weld in structure as is appropriate to the job. Adding stabilizers to the micro apartments, will keep it all in place.
