Batteries are hot right now - literally in the case of Samsung's Galaxy Note 7.

The investigation into what caused the overheating in the smartphone concluded, unsurprisingly, that it was a fault in the design and manufacturing of the batteries.

But what also emerged was the growing pressure to deliver ever more from a smartphone within a confined space with Samsung's DJ Koh admitting that the company might have been asking too much of the battery.

That pressure will not lessen, either in the smartphone industry or in a range of others dependent on stored energy. If there's one area of technology where most consumers would like to see progress, it's in battery performance.

Whether it be in giving electric cars a greater range or in storing solar energy during the day for use in homes overnight, the race is on around the world to invent better batteries.

Tech Tent: Tech gets ready for Trump


It's safe to say that in Silicon Valley tech companies big and small you'd struggle to find many people who owned up to voting for Donald Trump last November. But an industry which tends to have an optimistic view of the world is already adapting to a political landscape very different from the one it expected.

Ten years ago I was running from San Francisco’s Moscone Centre to a nearby hotel to edit a piece for the Ten O’Clock News when my phone rang.

Those were the days, by the way, when phones were for making calls but all that was about to change.

Computing GCSE 'leaves girls and poorer students behind'

A revolution is under way in the teaching of computer science in schools in England - but it risks leaving girls and pupils from poorer backgrounds and ethnic minorities behind. That's the conclusion of academics who've studied data about the move from ICT as a national curriculum subject to computer science.

Four years ago, amid general disquiet that ICT was teaching children little more than how Microsoft Office worked, the government took the subject off the national curriculum. The idea was that instead schools should move to offering more rigorous courses in computer science - children would learn to code rather than how to do PowerPoint.

On Tech Tent this week we ask whether the tech industry is out of touch with the real world.

In the rush to disrupt every industry and to reinvent the way we live, do the tech utopians forget the negative impact some of their miraculous products can have on the lives and jobs of many people?

A woman browses the selection of ready meals, puts one in her handbag and leaves. Scenes from a viral video - not about shoplifting but about Amazon's vision of the future of retailing.
