The "$1 per Watt" barrier may not sound as impressive as the sound barrier, but this next-gen wind turbine is the first, and has an unusual design. The AeroCam's horizontal-axis, flat-blade shape has blades that're dynamically angled to maximize wind-catching. It's also compact, so can fit into urban environments, and captures wind from any direction. Plus, AeroCam turbines make less noise and vibration than conventional ones, wear out less quickly and cost less to build. They may even be cheaper than solar panels, so it seems like a win-win-win. Since a 250kW unit will cost $250,000, it'll be your energy suppliers, not you, that ends up owning one. [EnergyDaily and Inhabitat]
