Lithium ion batteries have lower energy density than goose fat but completely redesigning the plane could still enable an electric plane revolution
Pratt and Whitney’s Michael Winter gave an overview of future plane engines. He noted that lithium ion batteries have lower energy density than goose fat and honey. Rechargable batteries are not that far off in terms of cost for energy compared to fuels. The near and mid-term is larger and more efficient turbine engines. Electric …
