Watt's next for batteries? It'll be more of the same, not longer life, because physics and chemistry are hard

Nice idea; most of us have boxes of Wall-Warts for dead equipment. We are able to wield soldering irons better than many, I expect. Some good work has been done already in adopting figure-8 for input and now we need a standard for DC output cables. But not USB, precisely because it already has a power rating too low to be good. Then what to do about the current rating at each voltage? Mustn't overheat them. ??
I failed to make clear enough that my questions were not about Thumbs but about the 'slider' and whether it should be applied to the >form< or the >content< of the article. I understand thumbs but don't know WHO or WHAT one is Dis/Approving with the slider; the reporting, or the subject of the report.
I'm very pleased to see the amount of care that goes into filtering your posts. Without it the trash level would clearly rise to become unacceptable.
I am curious about the RATING system because I do not understand and cannot discover whether the Rating applies to the form or to the subject of the original article. Much of the reporting is good and some excellent; is THAT what I am rating ??
Some of the proposals/ideas/policies being discussed in articles are rubbish and some are sound; is the raw subject matter of the article what I am rating ??
What makes them different?
Speed Cameras round here are painted yellow so people learn to slow down even if the case contains no active camera. Some social benefit occurs.
What is different about NCPR Cameras? If people knew where they were (and were concerned) they would take care in those neghbourhoods. If people don't know where they are that social benefit is lost.
