Molecular mechanical computing design 2000 times more energy computation efficient than the upper bound estimate for the human brain

Up until now computer designs that have been theoretically known have been less energy efficient than the human brain. We could project supercomputers that could reach an exaFLOP and perhaps a zettaFLOP but the designs typically need megawatts to gigawatts of power. ExaFLOP (10^18 operations per second) Onchip photonics at low power a key aspect …

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 …
