Batteries as good as petrol.

Researchers have come up with a battery design that appears to have the charactistics required for rapid charging, thus allowing fast refuelling at refuelling stations.  There may remain issues of weight and recycling but in the balance they are looking like a good energy replacement for petrol in the transport industry.  Clean too.  (Though humanity still uses far more energy than than the  sun offers so we must cut consumption anyway.)
