It's just depressing how much batteries suck.
Why can't we buy AA batteries that last a month constant usage now? Probably because then we'd buy less batteries, and people are unlikely to buy more expensive batteries.
Anyway, some new startups working to shake things up would be cool IMHO.
- Daniel_Newby 17y ago50 milliamps for a month is equal to the energy produced by 50 grams of TNT. OK, so not kilotons, but not something you want to carry around either.
- axod 17y agoSo build some technology to make it ridiculously safe to carry around. Can't be that hard ;)
- jrockway 17y agoCurrent isn't energy, so no.
- Daniel_Newby 17y agoIn the context of a ~1.5 V AA battery (the grandparent comment's lament), current over time is energy. Regarding internal resistance, the resistance of all materials drops when they get sufficiently hot, and even a volt or two is enough to get an arc going. Once that happens it will spread until the entire battery is converted to plasma. Given the energy densities the other commenter hoped for, the propagation rate is likely to be at the speed of sound, in other words a high-order explosion. Which is not surprising given that such a battery would amount to a stick of dynamite with electrode layers spaced every few molecules.
