As the nation plows an average of $4 million dollars into each mile of fence, the only benefit is the slowed pace illegal crossings. Rael imagines a border blockade that enhances the communities by providing clean energy and water as well as communications and local trade.
His visualizes a large solar electric array along the border (parts of which are the sunniest portions of the US) to provide communities with clean reliable energy. Rael also included plans for integrated solar-thermal vacuum tubes that collect thermal heat in large underground tanks to be used by schools, commercial buildings and factories. The fence could also collect storm water to ease urban infrastructure costs and store and supply clean water.
