Whilst in the meantime the 40% efficient auto diesel engine is a likely
possibility in the near term. Ships' diesels can already exceed 50% efficiency
and with co-gen can get up to about 70% or so. I don't see a problem with 70%
efficiency.

I see that you made about 5 posts in this thread in under 10 minutes,
not a sign of thought in any of them. I don't owe you anything, google
for batteries and you will find out all you need to know.
