Aquanis will develop advanced plasma actuators and controls to reduce aerodynamic loads on wind turbine blades, facilitating the next generation of larger (20+ MW), smarter wind turbines. The technology contains no moving parts, instead using purely electrical plasma actuators on the blade that set the adjacent air in motion when powered. This system can change the lift and drag forces on turbine blades to reduce blade mechanical fatigue and enable the design of larger and cheaper blades. Currently effective at laboratory scales, Aquanis plans to improve the plasma actuator capabilities and field test a prototype plasma actuator system on a wind turbine.

Brown University is developing a power conversion device to maximize power production and reduce costs to capture energy from flowing water in rivers and tidal basins. Conventional methods to harness energy from these water resources face a number of challenges, including the costs associated with developing customized turbine technology to a specific site. Additionally, sites with sufficient energy exist near coastal habitats which depend on the natural water flow to transport nutrients. Brown University's tidal power conversion devices can continuously customize themselves by using an onboard computer and control software to respond to real-time measurements, which will increase tidal power conversion efficiency. Brown University's technology will allow for inexpensive installation and software upgrades and optimized layout of tidal power generators to maximize power generation and mitigate environmental impacts.
