The future of wind turbines could be bladeless

The design of Vortex's generators offers a potentially revolutionary shift from today's traditional designs, blades and all. One key facet of the Vortex design is that it uses less material than conventional turbines, meaning less maintenance as well as less noise. Vortex is not the only business looking to develop new ideas and technology in the field of wind energy. Kite Power Systems, for example, is a U.K.-based business that wants to use kites to harness wind energy. Earlier this year, CNBC spoke to researchers in the U.S. looking to develop vast wind turbines taller than the Eiffel Tower.According to Vortex co-founder David Suriol, the business is targeting the residential market. "My vision, and I think it's the vision of the team, is to change the landscape," he said.Looking at the bigger picture, the executive director of RenewableUK predicted a bright future when it came to both renewables in general and wind.
