This research redesigns long wind-turbine blades for low-wind-speed sites by shifting structural strength from the internal spar to the aerodynamic shell. The new “eggshell-like” design reduces bending under the blade’s own weight, requires less material, and lowers costs—helping make wind power cheaper than fossil fuels without relying on political action.

This research improves the lifespan of sodium-metal batteries, a cheaper and greener alternative to lithium-ion cells for renewable energy storage. By replacing copper with zinc as the supporting material, sodium forms smooth, stable deposits, extending battery life 15-fold. This innovation could deliver affordable, sustainable grid-scale energy storage.
