There is more at stake in battery development than longer-lasting AAs. In order for electric vehicles to compete with conventional models, car batteries must be cheaper, i.e. more efficient: “If the batteries could store more energy, automakers could use fewer of them, thus saving money. In conventional lithium-ion-battery manufacturing, electrode materials are applied in the form of slurry to metal foils. The thickness of the electrode is limited by the rate at which lithium ions can diffuse out of the material to reach an electrolyte.”
Looking back on our planet's early history offers a new (and less crazy) meaning for the idea of a "flat Earth."
According to the legendary investor, the best method is a blueprint for "extreme success.”
For generations, physicists have been searching for a quantum theory of gravity. But what if gravity isn't actually quantum at all?
