Meant to be towed out into the pacific ocean, Hydroelectric Waterfall Prison is meant to play upon the minds of its residents. The only view of the outside world is a desolate blue vastness that stretches beyond the horizon. The only sound from the outside world is the churning of the prison's waterfall. The walls inside are made from semi-transparent optical mirror which provides superimposed views into and through the cells. Oh, and everything is tinted a mustardy yellow. It's enough to drive an inmate mad.
But that's not the full extent of this prison's wonders. The steady lapping of waves against a series of Tyson turbines feeds the structure, powers the waterfall and even exports power to the mainland via a massive tether. All in all, the effect is otherworldly. We'll take two, please.
