New Guy Here

Retired draftsman/designer. I’ve always had an interest in electric cars, they truely are the way of the future. I’m especially excited due to the recent advancements that graphene has to offer in battery development. This forum has probably discussed it but here’s a link just the same.

Graphene improves lithium-ion battery capacity and recharge rate by 10x | ExtremeTech

Just a question: If an average size electric car could run on a generator alone how big would the generator have to be, 15kw 20kw?
