Car troubles

Our elder son had to use our car to get home today (to London) as his car would not start. I think he needs a new battery. The rain last night probably did not help as some of the leads would have been damp. The joys of autumn and cooler, wetter times!

We now have pansies planted in the rear garden. These should be in flower until the spring.

UPDATE 1320z: Green Flag (rescue) have now been and said the battery is charging OK and had loose connectors. It has been left running for 15-20 minutes. Our son will collect on Wednesday.

A breakthrough in battery technology?

The ExtremeTech website has reported a possible major major (i.e. game changing) breakthrough in Li-Ion battery technology with the headlines:  New lithium-ion battery design that’s 2,000 times more powerful, recharges 1,000 times faster

If this turns out to be technology that can indeed be commercialised, then just imagine the possibilities: (1) electric cars with far lighter batteries, or electric car batteries with much greater range, (2) mobile phones with tiny batteries that can be charged in a minute or so, (3) portable HF transceivers that last for days between charges.
