Re: Battery Times
Sadly electric motors and batteries are all up on the 90% plus efficiency range.
What is missing is a high energy density battery, and those are already approaching the limits of lithium, and lithium is, in the periodic table, the best element there is.
Even lithium air, where at least some of the weight is in the atmosphere to begin with, is only just able to match a tank of hydrocarbon fuel.
And the technology is massively difficult to deploy.
Storing electrical energy efficiently and without a weight penalty is a huge problem which if we could crack it, would transform a lot of things.
Aircraft for example, only fly because of the energy density of hydrocarbon fuel...
