As reluctant as I am to try to add anything sensible to a Zarkov thread ....

Battery technology is one thing I'd really like to see advance soon.
If they could be made with about 1/3 the energy density of regular petrol it'd be a real game-changer. The reason being that a typical petrol engine is about 30% efficient, a good electric motor about 90% or so efficient, so if the batteries were about 1/3 as good a petrol it should be possible to get a car, etc, doing about the same job. (that right?)
But as always, recharge times are likely to be somewhat limiting.
We already know how to make almost totally clean electrical power and many other quite clever things, I'm still at somewhat of a loss to understand why they are not taken up ASAP.
