"and we're excited to be the first to bring you news of it!" From Sandia National Laboratories report January 2020: Conclusions and future directions Experimentally demonstrated • optimum spacing between foils (not shown) Observed asymmetries likely due to flow instabilities • reduces viable AoA range • most dramatic in closed air-jet and no-load configurations 18% (-1/3 of Betz limit) mechanical efficiency achieved in stable operation • -1/2 of Betz limit intermittently achieved in unstable mode
